5 years after a heart throbbing Martian touchdown, Curiosity is climbing Vera Rubin Ridge in search of “aqueous minerals” and “clays” for clues to possible past life while capturing “truly breathtaking” vistas of humongous Mount Sharp – her primary destination – and the stark eroded rim of the Gale Crater landing zone from ever higher elevations, NASA scientists tell Universe Today in a new mission update.

“Curiosity is doing well, over five years into the mission,” Michael Meyer, NASA Lead Scientist, Mars Exploration Program, NASA Headquarters told Universe Today in an interview.

“A key finding is the discovery of an extended period of habitability on ancient Mars.”

The car-sized rover soft landed on Mars inside Gale Crater on August 6, 2012 using the ingenious and never before tried “sky crane” system.

A rare glimpse of Curiosity’s arm and turret mounted skyward pointing drill is illustrated with our lead mosaic from Sol 1833 of the robot’s life on Mars – showing a panoramic view around the alien terrain from her current location in October 2017 while actively at work analyzing soil samples.

“Your mosaic is absolutely gorgeous!’ Jim Green, NASA Director Planetary Science Division, NASA Headquarters, Washington D.C., told Universe Today

“We are at such a height on Mt Sharp to see the rim of Gale Crater and the top of the mountain. Truly breathtaking.”

The rover has ascended more than 300 meters in elevation over the past 5 years of exploration and discovery from the crater floor to the mountain ridge. She is driving to the top of Vera Rubin Ridge at this moment and always on the lookout for research worthy targets of opportunity.

Additionally, the Sol 1833 Vera Rubin Ridge mosaic, stitched by the imaging team of Ken Kremer and Marco Di Lorenzo, shows portions of the trek ahead to the priceless scientific bounty of aqueous mineral signatures detected by spectrometers years earlier from orbit by NASA’s fleet of Red Planet orbiters.

“Curiosity is on Vera Rubin Ridge (aka Hematite Ridge) – it is the first aqueous mineral signature that we have seen from space, a driver for selecting Gale Crater,” NASA HQ Mars Lead Scientist Meyer elaborated.

“And now we have access to it.”

The Sol 1833 photomosaic illustrates Curiosity maneuvering her 7 foot long (2 meter) robotic arm during a period when she was processing and delivering a sample of the “Ogunquit Beach” for drop off to the inlet of the CheMin instrument earlier in October. The “Ogunquit Beach” sample is dune material that was collected at Bagnold Dune II this past spring.

The sample drop is significant because the drill has not been operational for some time.

“Ogunquit Beach” sediment materials were successfully delivered to the CheMin and SAM instruments over the following sols and multiple analyses are in progress.

To date three CheMin integrations of “Ogunquit Beach” have been completed. Each one brings the mineralogy into sharper focus.

Researchers used the Mastcam on NASA’s Curiosity Mars rover to gain this detailed view of layers in “Vera Rubin Ridge” from just below the ridge. The scene combines 70 images taken with the Mastcam’s right-eye, telephoto-lens camera, on Aug. 13, 2017.

What’s the status of the rover health at 5 years, the wheels and the drill?

“All the instruments are doing great and the wheels are holding up,” Meyer explained.

“When 3 grousers break, 60% life has been used – this has not happened yet and they are being periodically monitored. The one exception is the drill feed (see detailed update below).”

NASA’s 1 ton Curiosity Mars Science Laboratory (MSL) rover is now closer than ever to the mineral signatures that were the key reason why Mount Sharp was chosen as the robots landing site years ago by the scientists leading the unprecedented mission.

Along the way from the ‘Bradbury Landing’ zone to Mount Sharp, six wheeled Curiosity has often been climbing. To date she has gained over 313 meters (1027 feet) in elevation – from minus 4490 meters to minus 4177 meters today, Oct. 19, 2017, said Meyer.

The low point was inside Yellowknife Bay at approx. minus 4521 meters.

VRR alone stands about 20 stories tall and gains Curiosity approx. 65 meters (213 feet) of elevation to the top of the ridge. Overall the VRR traverse is estimated by NASA to take drives totaling more than a third of a mile (570 m).

“Vera Rubin Ridge” or VRR is also called “Hematite Ridge.” It’s a narrow and winding ridge located on the northwestern flank of Mount Sharp. It was informally named earlier this year in honor of pioneering astrophysicist Vera Rubin.

The intrepid robot reached the base of the ridge in early September.

The ridge possesses steep cliffs exposing stratifications of large vertical sedimentary rock layers and fracture filling mineral deposits, including the iron-oxide mineral hematite, with extensive bright veins.

VRR resists erosion better than the less-steep portions of the mountain below and above it, say mission scientists.

What’s ahead for Curiosity in the coming weeks and months exploring VRR before moving onward and upwards to higher elevation?

“Over the next several months, Curiosity will explore Vera Rubin Ridge,” Meyer replied.

“This will be a big opportunity to ground-truth orbital observations. Of interest, so far, the hematite of VRR does not look that different from what we have been seeing all along the Murray formation. So, big question is why?”

“The view from VRR also provides better access to what’s ahead in exploring the next aqueous mineral feature – the clay, or phyllosilicates, which can be indicators of specific environments, putting constraints on variables such as pH and temperature,” Meyer explained.

The clay minerals or phyllosilicates form in more neutral water, and are thus extremely scientifically interesting since pH neutral water is more conducive to the origin and evolution of Martian microbial life forms, if they ever existed.

How far away are the clays ahead and when might Curiosity reach them?

“As the crow flies, the clays are about 0.5 km,” Meyer replied. “However, the actual odometer distance and whether the clays are where we think they are – area vs. a particular location – can add a fair degree of variability.”

The clay rich area is located beyond the ridge.

Over the past few months Curiosity make rapid progress towards the hematite-bearing location of Vera Rubin Ridge after conducting in-depth exploration of the Bagnold Dunes earlier this year.

“Vera Rubin Ridge is a high-standing unit that runs parallel to and along the eastern side of the Bagnold Dunes,” said Mark Salvatore, an MSL Participating Scientist and a faculty member at Northern Arizona University, in a mission update.

“From orbit, Vera Rubin Ridge has been shown to exhibit signatures of hematite, an oxidized iron phase whose presence can help us to better understand the environmental conditions present when this mineral assemblage formed.”

Curiosity is using the science instruments on the mast, deck and robotic arm turret to gather detailed research measurements with the cameras and spectrometers. The pair of miniaturized chemistry lab instruments inside the belly – CheMin and SAM – are used to analyze the chemical and elemental composition of pulverized rock and soil gathered by drilling and scooping selected targets during the traverse.

A key instrument is the drill which has not been operational. I asked Meyer for a drill update.

“The drill feed developed problems retracting (two stabilizer prongs on either side of the drill retract, controlling the rate of drill penetration),” Meyer replied.

“Because the root cause has not been found (think FOD) and the concern about the situation getting worse, the drill feed has been retracted and the engineers are working on drilling without the stabilizing prongs.”

“Note, a consequence is that you can still drill and collect sample but a) there is added concern about getting the drill stuck and b) a new method of delivering sample needs to be developed and tested (the drill feed normally needs to be moved to move the sample into the chimera). One option that looks viable is reversing the drill – it does work and they are working on the scripts and how to control sample size.”

Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rover’s long term scientific expedition on the Red Planet.

“Lower Mount Sharp was chosen as a destination for the Curiosity mission because the layers of the mountain offer exposures of rocks that record environmental conditions from different times in the early history of the Red Planet. Curiosity has found evidence for ancient wet environments that offered conditions favorable for microbial life, if Mars has ever hosted life,” says NASA.

Stay tuned. In part 2 we’ll discuss the key findings from Curiosity’s first 5 years exploring the Red Planet.

As of today, Sol 1850, Oct. 19, 2017, Curiosity has driven over 10.89 miles (17.53 kilometers) since its August 2012 landing inside Gale Crater from the landing site to the ridge, and taken over 445,000 amazing images.

Opportunity Starts Historic Descent of Tantalizing Martian Gully to Find Out How Was It Carved

From the precipice of “Perseverance Valley” NASA’s teenaged Red Planet robot Opportunity has begun the historic first ever descent of an ancient Martian gully – that’s simultaneously visually and scientifically “tantalizing” – on an expedition to discern ‘How was it carved?’; by water or other means, Jim Green, NASA’s Planetary Sciences Chief tells Universe Today.

Since water is an indispensable ingredient for life as we know it, the ‘opportunity’ for Opportunity to study a “possibly water-cut” gully on Mars for the first time since they were discovered over four decades ago by NASA orbiters offers a potential scientific bonanza.

“Gullies on Mars have always been of intense interest since first observed by our orbiters,” Jim Green, NASA’s Planetary Sciences Chief explained to Universe Today.

“How were they carved? muses Green. “Water is a natural explanation but this is another planet. Now we have a chance to find out for real!”

Their origin and nature has been intensely debated by researchers for decades. But until now the ability to gather real ‘ground truth’ science by robotic or human explorers has remained elusive.

“This will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, told Universe Today.

“Perseverance Valley” is located along the eroded western rim of gigantic Endeavour crater – as illustrated by our exclusive photo mosaics herein created by the imaging team of Ken Kremer and Marco Di Lorenzo.

After arriving at the upper entryway to “Perseverance Valley” the six wheeled rover drove back and forth to gather high resolution imagery of the inner slope for engineers to create a 3D elevation map and plot a safe driving path down – as illustrated in our lead mosaic showing the valley and extensive wheel tracks at left, center and right.

Having just this week notched an astounding 4800 Sols roving the Red Planet, NASA’s resilient Opportunity rover has started driving down from the top of “Perseverance Valley” from the spillway overlooking the upper end of the ancient fluid-carved Martian valley into the unimaginably vast eeriness of alien Endeavour crater.

Water, ice or wind may have flowed over the crater rim and into the crater from the spillway.

“It is a tantalizing scene,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a statement. “You can see what appear to be channels lined by boulders, and the putative spillway at the top of Perseverance Valley. We have not ruled out any of the possibilities of water, ice or wind being responsible.”

Toward the right side of this scene is a broad notch in the crest of the western rim of Endeavour Crater. Wheel tracks in that area were left by NASA’s Mars Exploration Rover Opportunity as it observed “Perseverance Valley” from above in the spring of 2017. The valley is a major destination for the rover’s extended mission. It descends out of sight on the inner slope of the rim, extending down and eastward from that notch. The component pancam images for this view from a position outside the crater were taken during the span of June 7 to June 19, 2017, sols 4753 to 4765.

“With the latest drive on sol 4782, Opportunity began the long drive down the floor of Perseverance Valley here on Endeavour crater, says Larry Crumpler, a rover science team member from the New Mexico Museum of Natural History & Science.

“This is rather historic in that it represents the first time that a rover has driven down an apparent water-cut valley on Mars. Over the next few months Opportunity will explore the floor and sides of the valley for evidence of the scale and timing of the fluvial activity, if that is what is represents.”

NASA’s unbelievably long lived Martian robot reached a “spillway” at the top of “Perseverance Valley” in May after driving southwards for weeks from the prior science campaign at a crater rim segment called “Cape Tribulation.”

“Investigations in the coming weeks will “endeavor” to determine whether this valley was eroded by water or some other dry process like debris flows,” explains Crumpler.

“It certainly looks like a water cut valley. But looks aren’t good enough. We need additional evidence to test that idea.”

The valley slices downward from the crest line through the rim from west to east at a breathtaking slope of about 15 to 17 degrees – and measures about two football fields in length!

Huge Endeavour crater spans some 22 kilometers (14 miles) in diameter on the Red Planet. Perseverance Valley slices eastwards at approximately the 8 o’clock position of the circular shaped crater. It sits just north of a rim segment called “Cape Byron.”

Why go and explore the gully at Perseverance Valley?

“Opportunity will traverse to the head of the gully system [at Perseverance] and head downhill into one or more of the gullies to characterize the morphology and search for evidence of deposits,” Arvidson elaborated to Universe Today.

“Hopefully test among dry mass movements, debris flow, and fluvial processes for gully formation. The importance is that this will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes. Will search for cross bedding, gravel beds, fining or coarsening upward sequences, etc., to test among hypotheses.”

Exploring the ancient valley is the main science destination of the current two-year extended mission (EM #10) for the teenaged robot, that officially began Oct. 1, 2016. It’s just the latest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004.

Before starting the gully descent, Opportunity conducted a walkabout at the top of the Perseverance Valley in the spillway to learn more about the region before driving down.

“The walkabout is designed to look at what’s just above Perseverance Valley,” said Opportunity Deputy Principal Investigator Ray Arvidson of Washington University in St. Louis, in a statwemwent. “We see a pattern of striations running east-west outside the crest of the rim.”

“We want to determine whether these are in-place rocks or transported rocks,” Arvidson said. “One possibility is that this site was the end of a catchment where a lake was perched against the outside of the crater rim. A flood might have brought in the rocks, breached the rim and overflowed into the crater, carving the valley down the inner side of the rim. Another possibility is that the area was fractured by the impact that created Endeavour Crater, then rock dikes filled the fractures, and we’re seeing effects of wind erosion on those filled fractures.”

Having begun the long awaited gully descent, further movements are temporarily on hold since the start of the solar conjunction period which blocks communications between Mars and Earth for about the next two weeks, since Mars is directly behind the sun.

In the meantime, Opportunity will still collect very useful panoramic images and science data while standing still.

The solar conjunction moratorium on commanding extends from July 22 to Aug. 1, 2017.

As of today, July 27, 2017, long lived Opportunity has survived over 4800 Sols (or Martian days) roving the harsh environment of the Red Planet.

Opportunity has taken over 221,625 images and traversed over 27.95 miles (44.97 kilometers.- more than a marathon.

See our updated route map below. It shows the context of the rovers over 13 year long traverse spanning more than the 26 mile distance of a Marathon runners race.

The rover surpassed the 27 mile mark milestone on November 6, 2016 (Sol 4546) and will soon surpass the 28 mile mark.

As of Sol 4793 (July 18, 2017) the power output from solar array energy production is currently 332 watt-hours with an atmospheric opacity (Tau) of 0.774 and a solar array dust factor of 0.534, before heading into another southern hemisphere Martian winter later in 2017. It will count as Opportunity’s 8th winter on Mars.

Meanwhile Opportunity’s younger sister rover Curiosity traverses up the lower sedimentary layers at the base of Mount Sharp.

And NASA continues building the next two robotic missions due to touch down in 2018 and 2020.

NASA as well is focusing its human spaceflight efforts on sending humans on a ‘Journey to Mars’ in the 2030s with the Space Launch System (SLS) mega rocket and Orion deep space crew capsule.

You can catch a glimpse of what its like to see NASA’s Curiosity Mars rover simultaneously high overhead from orbit and trundling down low across the Red Planet’s rocky surface as she climbs the breathtaking terrain of Mount Sharp – as seen in new images from NASA we have stitched together into a mosaic view showing the perspective views; see above.

Earlier this month on June 5, researchers commanded NASA’s Mars Reconnaissance Orbiter (MRO) to image the car sized Curiosity rover from Mars orbit using the spacecrafts onboard High Resolution Imaging Science Experiment (HiRISE) telescopic camera during Sol 1717 of her Martian expedition – see below.

HiRISE is the most powerful telescope ever sent to Mars.

And as she does nearly every Sol, or Martian day, Curiosity snapped a batch of new images captured from Mars surface using her navigation camera called navcam – likewise on Sol 1717.

Since NASA just released the high resolution MRO images of Curiosity from orbit, we assembled together the navcam camera raw images taken simultaneously on June 5 (Sol 1717), in order to show the actual vista seen by the six wheeled robot from a surface perspective on the same day.

The lead navcam photo mosaic shows a partial rover selfie backdropped by the distant rim of Gale Crater – and was stitched together by the imaging team of Ken Kremer and Marco Di Lorenzo.

The feature that appears bright blue at the center of this scene is NASA’s Curiosity Mars rover amid tan rocks and dark sand on Mount Sharp, as viewed by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter on June 5, 2017. The rover is about 10 feet long and not really as blue as it looks here.

Right now NASA’s Curiosity Mars Science Laboratory (MSL) rover is approaching her next science destination named “Vera Rubin Ridge” while climbing up the lower reaches of Mount Sharp, the humongous mountain that dominates the rover’s landing site inside Gale Crater.

“When the MRO image was taken, Curiosity was partway between its investigation of active sand dunes lower on Mount Sharp, and “Vera Rubin Ridge,” a destination uphill where the rover team intends to examine outcrops where hematite has been identified from Mars orbit,” says NASA.

“HiRISE has been imaging Curiosity about every three months, to monitor the surrounding features for changes such as dune migration or erosion.”

The MRO image has been color enhanced and shows Curiosity as a bright blue feature. It is currently traveling on the northwestern flank of Mount Sharp. Curiosity is approximately 10 feet long and 9 feet wide (3.0 meters by 2.8 meters).

“The exaggerated color, showing differences in Mars surface materials, makes Curiosity appear bluer than it really looks. This helps make differences in Mars surface materials apparent, but does not show natural color as seen by the human eye.”

Curiosity is making rapid progress towards the hematite-bearing location of Vera Rubin Ridge after conducting in-depth exploration of the Bagnold Dunes earlier this year.

“Vera Rubin Ridge is a high-standing unit that runs parallel to and along the eastern side of the Bagnold Dunes,” says Mark Salvatore, an MSL Participating Scientist and a faculty member at Northern Arizona University, in a new mission update.

“From orbit, Vera Rubin Ridge has been shown to exhibit signatures of hematite, an oxidized iron phase whose presence can help us to better understand the environmental conditions present when this mineral assemblage formed.”

Curiosity will use her cameras and spectrometers to elucidate the origin and nature of Vera Rubin Ridge and potential implications or role in past habitable environments.

“The rover will turn its cameras to Vera Rubin Ridge for another suite of high resolution color images, which will help to characterize any observed layers, fractures, or geologic contacts. These observations will help the science team to determine how Vera Rubin Ridge formed and its relationship to the other geologic units found within Gale Crater.”

To reach Vera Rubin Ridge, Curiosity is driving east-northeast around two small patches of dunes just to the north. She will then turn “southeast and towards the location identified as the safest place for Curiosity to ascend the ridge. Currently, this ridge ascent point is approximately 370 meters away.”

Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.

“Lower Mount Sharp was chosen as a destination for the Curiosity mission because the layers of the mountain offer exposures of rocks that record environmental conditions from different times in the early history of the Red Planet. Curiosity has found evidence for ancient wet environments that offered conditions favorable for microbial life, if Mars has ever hosted life,” says NASA.

As of today, Sol 1733, June 21, 2017, Curiosity has driven over 10.29 miles (16.57 kilometers) since its August 2012 landing inside Gale Crater, and taken over 420,000 amazing images.

Now well into her 13th year roving the Red Planet, NASA’s astoundingly resilient Opportunity rover has arrived at the precipice of “Perseverance Valley” – overlooking the upper end of an ancient fluid-carved valley on Mars “possibly water-cut” that flows down into the unimaginably vast eeriness of alien Endeavour crater.

Opportunity’s unprecedented goal ahead is to go ‘Where No Rover Has Gone Before!’

In a remarkable first time feat and treat for having ‘persevered’ so long on the inhospitably frigid Martian terrain, Opportunity has been tasked by her human handlers to drive down a Martian gully carved billions of years ago – by a fluid that might have been water – and conduct unparalleled scientific exploration, that will also extend into the interior of Endeavour Crater for the first time.

No Mars rover has done that before.

“This will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, told Universe Today.

“Opportunity has arrived at the head of Perseverance Valley, a possible water-cut valley here at a low spot along the rim of the 22-km diameter Endeavour impact crater,” says Larry Crumpler, a rover science team member from the New Mexico Museum of Natural History & Science.

NASA’s unbelievably long lived Martian robot reached a “spillway” at the top of “Perseverance Valley” in May after driving southwards for weeks from the prior science campaign at a crater rim segment called “Cape Tribulation.”

“The next month or so will be an exciting time, for no rover has ever driven down a potential ancient water-cut valley before,” Crumpler gushes.

“Perseverance Valley” is located along the eroded western rim of gigantic Endeavour crater – as illustrated by our exclusive photo mosaics herein created by the imaging team of Ken Kremer and Marco Di Lorenzo.

Read an Italian language version of this story here by Marco Di Lorenzo.

The mosaics show the “spillway” as the entry point to the ancient valley.

“Investigations in the coming weeks will “endeavor” to determine whether this valley was eroded by water or some other dry process like debris flows,” explains Crumpler.

“It certainly looks like a water cut valley. But looks aren’t good enough. We need additional evidence to test that idea.”

The valley slices downward from the crest line through the rim from west to east at a breathtaking slope of about 15 to 17 degrees – and measures about two football fields in length!

Huge Endeavour crater spans some 22 kilometers (14 miles) in diameter on the Red Planet. Perseverance Valley slices eastwards at approximately the 8 o’clock position of the circular shaped crater. It sits just north of a rim segment called “Cape Byron.”

Why go and explore the gully at Perseverance Valley?

“Opportunity will traverse to the head of the gully system [at Perseverance] and head downhill into one or more of the gullies to characterize the morphology and search for evidence of deposits,” Arvidson elaborated.

“Hopefully test among dry mass movements, debris flow, and fluvial processes for gully formation. The importance is that this will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes. Will search for cross bedding, gravel beds, fining or coarsening upward sequences, etc., to test among hypotheses.”

Exploring the ancient valley is the main science destination of the current two-year extended mission (EM #10) for the teenaged robot, that officially began Oct. 1, 2016. It’s just the latest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004.

What are the immediate tasks ahead that Opportunity must accomplish before descending down the gully to thoroughly and efficiently investigate the research objectives?

In a nutshell, extensive imaging from a local high point promontory to create a long-baseline 3 D stereo image of the valley and a “walk-about” to assess the local geology.

The rover is collecting images from two widely separated points at a dip at the valley spillway to build an “extraordinarily detailed three-dimensional analysis of the terrain” called a digital elevation map.

“Opportunity has been working on a panorama from the overlook for the past couple of sols. The idea is to get a good overview of the valley from a high point before driving down it,” Crumpler explains.

“But before we drive down the valley, we want to get a good sense of the geologic features here on the head of the valley. It could come in handy as we drive down the valley and may help us understand some things, particularly the lithology of any materials we find on the valley floor or at the terminus down near the crater floor.”

“So we will be doing a short “walk-about” here on the outside of the crater rim near the “spillway” into the valley.”

“We will drive down it to further assess its origin and to further explore the structure and stratigraphy of this large impact crater.”

NASA’s Opportunity Mars rover passed near this small, 90-foot-wide and relatively fresh crater in April 2017, during the 45th anniversary of the Apollo 16 mission to the moon. The rover team chose to call it “Orion Crater,” after the Apollo 16 lunar module, Orion, which carried astronauts John Young and Charles Duke to and from the surface of the moon in April 1972 while crewmate Ken Mattingly piloted the Apollo 16 command module, Casper, in orbit around the moon.

The six wheeled rover landed on Mars on January 24, 2004 PST on the alien Martian plains at Meridiani Planum – as the second half of a stupendous sister act.

Expected to last just 3 months or 90 days, Opportunity has now endured nearly 13 ½ years or an unfathomable 53 times beyond the “warrantied” design lifetime.

Her twin sister Spirit, had successfully touched down 3 weeks earlier on January 3, 2004 inside 100-mile-wide Gusev crater and survived more than six years.

Opportunity has been exploring Endeavour almost six years – since arriving at the humongous crater in 2011. Endeavour crater was formed when it was carved out of the Red Planet by a huge meteor impact billions of years ago.

“Endeavour crater dates from the earliest Martian geologic history, a time when water was abundant and erosion was relatively rapid and somewhat Earth-like,” explains Crumpler.

Exactly what the geologic process was that carved Perseverance Valley into the rim of Endeavour Crater billions of years ago has not yet been determined, but there are a wide range of options researchers are considering.

“Among the possibilities: It might have been flowing water, or might have been a debris flow in which a small amount of water lubricated a turbulent mix of mud and boulders, or might have been an even drier process, such as wind erosion,” say NASA scientists.

“The mission’s main objective with Opportunity at this site is to assess which possibility is best supported by the evidence still in place.”

Extensive imaging with the mast mounted pancam and navcam cameras is currently in progress.

“The long-baseline stereo imaging will be used to generate a digital elevation map that will help the team carefully evaluate possible driving routes down the valley before starting the descent,” said Opportunity Project Manager John Callas of JPL, in a statement.

“Reversing course back uphill when partway down could be difficult, so finding a path with minimum obstacles will be important for driving Opportunity through the whole valley. Researchers intend to use the rover to examine textures and compositions at the top, throughout the length and at the bottom, as part of investigating the valley’s history.”

The team is also dealing with a new wheel issue and evaluating fixes. The left-front wheel is stuck due to an actuator stall.

“The rover experienced a left-front wheel steering actuator stall on Sol 4750 (June 4, 2017) leaving the wheel ‘toed-out’ by 33 degrees,” the team reported in a new update.

Thus the extensive Pancam panorama is humorously being called the “Sprained Ankle Panorama.” Selected high-value targets of the surrounding area will be imaged with the full 13-filter Pancam suite.

After reaching the bottom of Perseverance Valley, Opportunity will explore the craters interior for the first time during the mission.

“Once down at the end of the valley, Opportunity will be directed to explore the crater fill on a drive south at the foot of the crater walls,” states Crumpler.

As of today, June 17, 2017, long lived Opportunity has survived over 4763 Sols (or Martian days) roving the harsh environment of the Red Planet.

Opportunity has taken over 220,800 images and traversed over 27.87 miles (44.86 kilometers) – more than a marathon.

See our updated route map below. It shows the context of the rovers over 13 year long traverse spanning more than the 26 mile distance of a Marathon runners race.

The rover surpassed the 27 mile mark milestone on November 6, 2016 (Sol 4546).

As of Sol 4759 (June 13, 2017) the power output from solar array energy production is currently 343 watt-hours with an atmospheric opacity (Tau) of 0.842 and a solar array dust factor of 0.529, before heading into another southern hemisphere Martian winter later in 2017. It will count as Opportunity’s 8th winter on Mars.

“The science team is really jazzed at starting to see this area up close and looking for clues to help us distinguish among multiple hypotheses about how the valley formed,” said Opportunity Project Scientist Matt Golombek of NASA’s Jet Propulsion Laboratory, Pasadena, California.

Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the lower sedimentary layers at the base of Mount Sharp.

And NASA continues building the next two robotic missions due to touch down in 2018 and 2020.

NASA as well is focusing its human spaceflight effort on sending humans on a ‘Journey to Mars’ in the 2030s with the Space Launch System (SLS) mega rocket and Orion deep space crew capsule.

Trump Proposes $19.1 Billion 2018 NASA Budget, Cuts Earth Science and Education

The Trump Administration has proposed a $19.1 Billion NASA budget request for Fiscal Year 2018, which amounts to a $0.5 Billion reduction compared to the recently enacted FY 2017 NASA Budget. Although it maintains many programs such as human spaceflight, planetary science and the Webb telescope, the budget also specifies significant cuts and terminations to NASA’s Earth Science and manned Asteroid redirect mission as well as the complete elimination of the Education Office.

Overall NASA’s FY 2018 budget is cut approximately 3%, or $560 million, for the upcoming fiscal year starting in October 2017 as part of the Trump Administration’s US Federal Budget proposal rolled out on May 23, and quite similar to the initial outline released in March.

The cuts to NASA are smaller compared to other Federal science agencies also absolutely vital to the health of US scientific research – such as the NIH, the NSF, the EPA, DOE and NIST which suffer unconscionable double digit slashes of 10 to 20% or more.

The highlights of NASA’s FY 2018 Budget were announced by NASA acting administrator Robert Lightfoot during a ‘State of NASA’ speech to agency employees held at NASA HQ, Washington, D.C. and broadcast to the public live on NASA TV.

Lightfoot’s message to NASA and space enthusiasts was upbeat overall.

“What this budget tells us to do is to keep going!” NASA acting administrator Robert Lightfoot said.

“Keep doing what we’ve been doing. It’s very important for us to maintain that course and move forward as an agency with all the great things we’re doing.”

“I want to reiterate how proud I am of all of you for your hard work – which is making a real difference around the world. NASA is leading the world in space exploration, and that is only possible through all of your efforts, every day.”

“We’re pleased by our top line number of $19.1 billion, which reflects the President’s confidence in our direction and the importance of everything we’ve been achieving.”

Lightfoot recalled the recent White House phone call from President Trump to NASA astronaut & ISS Station Commander Peggy Whitson marking her record breaking flight for the longest cumulative time in space by an American astronaut.

Thus Lightfoot’s vision for NASA has three great purposes – Discover, Explore, and Develop.

“NASA has a historic and enduring purpose. It can be summarized in three major strategic thrusts: Discover, Explore, and Develop. These correspond to our missions of scientific discovery, missions of exploration, and missions of new technology development in aeronautics and space systems.”

Lightfoot further recounted the outstanding scientific accomplishments of NASA’s Mars rover and orbiters paving the path for the agencies plans to send humans on a ‘Journey to Mars’ in the 2030s.

“We’ve had a horizon goal for some time now of reaching Mars, and this budget sustains that work and also provides the resources to keep exploring our solar system and look beyond it.”

Lightfoot also pointed to upcoming near term science missions- highlighting a pair of Mars landers – InSIGHT launching next year as well as the Mars 2020 rover. Also NASA’s next great astronomical observatory – the James Webb Space Telescope (JWST).

“In science, this budget supports approximately 100 missions: 40 missions currently preparing for launch & 60 operating missions.”

“The James Webb Space Telescope is built!” Lightfoot gleefully announced.

“It’s done testing at Goddard and now has moved to Johnson for tests to simulate the vacuum of space.”

JWST is the scientific successor to the Hubble Space Telescope and slated for launch in Oct. 2018. The budget maintains steady support for Webb.

The Planetary Sciences division receives excellent support with a $1.9 Billion budget request. It includes solid support for the two flagship missions – Mars 2020 and Europa Clipper as well as the two new Discovery class missions selected -Lucy and Psyche.

“The budget keeps us on track for the next selection for the New Frontiers program, and includes formulation of a mission to Jupiter’s moon Europa.”

SLS and Orion are making great progress. They are far beyond concepts, and as I mentioned, components are being tested in multiple ways right now as we move toward the first flight of that integrated system.”

NASA is currently targeting the first integrated launch of SLS and Orion on the uncrewed Exploration Mission-1 (EM-1) for sometime in 2019.

Top NASA managers recently decided against adding a crew of two astronauts to the flight after conducting detailed agency wide studies at the request of the Trump Administration.

NASA would have needed an additional $600 to $900 to upgrade EM-1 with humans.

Unfortunately Trump’s FY 2018 NASA budget calls for a slight reduction in development funding for both SLS and Orion – thus making a crewed EM-1 flight fiscally unviable.

It was lifted out of the welder (top) after final welding was just completed at NASA’s Michoud Assembly Facility in New Orleans. Credit: Ken Kremer/kenkremer.com

The budget request does maintain full funding for both of NASA’s commercial crew vehicles planned to restore launching astronauts to low Earth orbit (LEO) and the ISS from US soil on US rockets – namely the crewed Dragon and CST-100 Starliner – currently under development by SpaceX and Boeing – thus ending our sole reliance on Russian Soyuz for manned launches.

“Working with commercial partners, NASA will fly astronauts from American soil on the first new crew transportation systems in a generation in the next couple of years.”

“We need commercial partners to succeed in low-Earth orbit, and we also need the SLS and Orion to take us deeper into space than ever before.”

Orion crew module pressure vessel for NASA’s Exploration Mission-1 (EM-1) is unveiled for the first time on Feb. 3, 2016 after arrival at the agency’s Kennedy Space Center (KSC) in Florida. It is secured for processing in a test stand called the birdcage in the high bay inside the Neil Armstrong Operations and Checkout (O&C) Building at KSC. Launch to the Moon is slated in 2018 atop the SLS rocket. Credit: Ken Kremer/kenkremer.com

However the Trump Administration has terminated NASA’s somewhat controversial plans for the Asteroid Redirect Mission (ARM) – initiated under the Obama Administration – to robotically retrieve a near Earth asteroid and redirect it to lunar orbit for a visit by a crewed Orion to gather unique asteroidal samples.

“While we are ending formulation of a mission to an asteroid, known as the Asteroid Redirect Mission, many of the central technologies in development for that mission will continue, as they constitute vital capabilities needed for future human deep space missions.”

Key among those vital capabilities to be retained and funded going forward is Solar Electric Propulsion (SEP).

“Solar electric propulsion (SEP) for our deep space missions is moving ahead as a key lynchpin.”

The Trump Administration’s well known dislike for Earth science and disdain of climate change has manifested itself in the form of the termination of 5 current and upcoming science missions.

NASA’s FY 2018 Earth Science budget suffers a $171 million cut to $1.8 Billion.

“While we are not proposing to move forward with Orbiting Carbon Observatory-3 (OCO-3), Plankton, Aerosol, Cloud, ocean Ecosystem (PACE), Climate Absolute Radiance and Refractivity Observatory Pathfinder (CLARREO PF), and the Radiation Budget Instrument (RBI), this budget still includes significant Earth Science efforts, including 18 Earth observing missions in space as well as airborne missions.”

The DSCOVR Earth-viewing instruments will also be shut down.

NASA’s Office of Education will also be terminated completely under the proposed FY 2018 budget and the $115 million of funding excised.

“While this budget no longer supports the formal Office of Education, NASA will continue to inspire the next generation through its missions and the many ways that our work excites and encourages discovery by learners and educators. Let me tell you, we are as committed to inspiring the next generation as ever.”

Congress will now have its say and a number of Senators, including Republicans says Trumps budget is DOA.

Curiosity Watches a Dust Devil Go Past

Tis a season of incredible wind driven activity on Mars like few before witnessed by our human emissaries ! Its summer on the Red Planet and the talented scientists directing NASA’s Curiosity rover have targeted the robots cameras so proficiently that they have efficiently spotted a multitude of ‘Dust Devils’ racing across across the dunes fields of Gale Crater– see below.

The ‘Dust Devils’ are actually mini tornadoes like those seen on Earth.

But in this case they are dancing delightfully in the Bagnold Dune fields on Mars, as Curiosity surpassed 1625 Sols, or Martian days of exciting exploration and spectacular science and discovery.

This sequence of images shows a dust-carrying whirlwind, called a dust devil, on lower Mount Sharp inside Gale Crater, as viewed by NASA’s Curiosity Mars Rover during the summer afternoon of Sol 1613 (Feb. 18, 2017). The navcam camera images are in pairs that were taken about 12 seconds apart, with an interval of about 90 seconds between pairs. Timing is accelerated and not fully proportional in this animation. Contrast has been modified to make frame-to-frame changes easier to see. A black frame provides a marker between repeats of the sequence. Credit: NASA/JPL-Caltech/TAMU

Furthermore they whip up the dust more easily in the lower gravity field on Mars compared to Earth. Mars gravity is about one third of Earth’s.

Right now it’s summer inside the rovers southern hemisphere landing site at Gale Crater. And summer is the windiest time of the Martian year.

“Dust devils are whirlwinds that result from sunshine warming the ground, prompting convective rising of air that has gained heat from the ground. Observations of Martian dust devils provide information about wind directions and interaction between the surface and the atmosphere,” as described by researchers.

So now is the best time to observe and photograph the dusty whirlwinds in action as they flitter amazingly across the craters surface carrying dust in their wake.

This sequence of images shows a dust-carrying whirlwind, called a dust devil, scooting across ground inside Gale Crater, as observed on the local summer afternoon of NASA’s Curiosity Mars Rover’s 1,597th Martian day, or sol (Feb. 1, 2017). Set within a broader southward view from the rover’s Navigation Camera, the rectangular area outlined in black was imaged multiple times over a span of several minutes to check for dust devils. Images from the period with most activity are shown in the inset area. The images are in pairs that were taken about 12 seconds apart, with an interval of about 90 seconds between pairs. Timing is accelerated in this animation. Credits: NASA/JPL-Caltech/TAMU

Therefore researchers are advantageously able to utilize Curiosity in a new research campaign that “focuses on modern wind activity in Gale” on the lower slope of Mount Sharp — a layered mountain inside the crater.

Indeed, this past month Curiosity began her second sand dune campaign focusing on investigating active dunes on the mountain’s northwestern flank that are ribbon-shaped linear dunes.

“In these linear dunes, the sand is transported along the ribbon pathway, while the ribbon can oscillate back and forth, side to side,” said Nathan Bridges, a Curiosity science team member at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, in a statement.

These new dunes are different from those investigated during the first dune campaign back in late 2015 and early 2016 that examined crescent-shaped dunes, including Namib Dune in our mosaic below.

The initial dune campaign actually involved the first ever up-close study of active sand dunes anywhere other than Earth, as I reported at the time.

By snapping a series of targeted images pointed in just the right direction using the rovers mast mounted navigation cameras, or navcams, the researchers have composed a series of ‘Dust Devil’ movies – gathered together here for your enjoyment.

“We’re keeping Curiosity busy in an area with lots of sand at a season when there’s plenty of wind blowing it around,” said Curiosity Project Scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory, Pasadena, California.

“One aspect we want to learn more about is the wind’s effect on sorting sand grains with different composition. That helps us interpret modern dunes as well as ancient sandstones.”

The movies amply demonstrate that Mars is indeed an active world and winds are by far the dominant force shaping and eroding the Red Planets alien terrain – despite the thin atmosphere less than 1 percent of Earth’s.

Indeed scientists believe that wind erosion over billions of years of time is what caused the formation of Mount Sharp at the center of Gale Crater by removing vast amounts of dust and sedimentary material — about 15,000 cubic miles (64,000 cubic kilometers) — as Mars evolved from a wet world to the dry, desiccated planet we see today.

Gale crater was originally created over 3.6 billion years ago when a gigantic asteroid or comet smashed into Mars. The devastating impact “excavated a basin nearly 100 miles (160 kilometers) wide. Sediments including rocks, sand and silt later filled the basin, some delivered by rivers that flowed in from higher ground surrounding Gale.”

Winds gradually carved away so much sediment and dirt that we are left with the magnificent mountain in view today.

The whirlwinds called “dust devils” have been recorded moving across terrain in the crater, in sequences of afternoon images taken several seconds apart.

The contrast has been enhanced to better show the dust devils in action.

Watch this short NASA video showing Martian Dust Devils seen by Curiosity:

The team is also using the probes downward-looking Mars Descent Imager (MARDI) camera for a straight down high resolution up-close view looking beneath the rover. The purpose is to check for daily movement of the dunes she is sitting on to see “how far the wind moves grains of sand in a single day’s time.”

This pair of images shows effects of one Martian day of wind blowing sand underneath NASA’s Curiosity Mars rover on a non-driving day for the rover. Each image was taken just after sundown by the rover’s downward-looking Mars Descent Imager (MARDI). The area of ground shown in the images spans about 3 feet (about 1 meter) left-to-right. The images were taken on Jan. 23, 2017 (Sol 1587) and Jan. 24, 2017 (Sol 1588). The day-apart images by MARDI were taken as a part of investigation of wind’s effects during Martian summer, the windiest time of year in Gale Crater. Credit: NASA/JPL-Caltech/MSSS

These dune investigations have to be done now, because the six wheeled robot will soon ascend Mount Sharp, the humongous layered mountain at the center of Gale Crater.

Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rovers long term scientific expedition on the Red Planet.

“Before Curiosity heads farther up Mount Sharp, the mission will assess movement of sand particles at the linear dunes, examine ripple shapes on the surface of the dunes, and determine the composition mixture of the dune material,” researchers said.

Curiosity is also using the science instruments on the robotic arm turret to gather detailed research measurements with the cameras and spectrometers.

As of today, Sol 1625, March 2, 2017, Curiosity has driven over 9.70 miles (15.61 kilometers) since its August 2012 landing inside Gale Crater, and taken over 391,000 amazing images.

Outstanding Opportunity Rover Making ‘Amazing New Discoveries’ 13 Years After Mars Touchdown – Scientist Tells UT

13 Years on Mars!

NASA’s truly outstanding Opportunity rover continues “making new discoveries about ancient Mars” as she commemorates 13 Years since bouncing to a touchdown on Mars, in a feat that is “truly amazing” – the deputy chief scientist Ray Arvidson told Universe Today exclusively.

Resilient Opportunity celebrated her 13th birthday on Sol 4623 on January 24, 2017 PST while driving south along the eroded rim of humongous Endeavour crater – and having netted an unfathomable record for longevity and ground breaking scientific discoveries about the watery environment of the ancient Red Planet.

“Reaching the 13th year anniversary with a functioning rover making new discoveries about ancient Mars on a continuing basis is truly amazing,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, told Universe Today.

Put another way Opportunity is 13 YEARS into her 3 MONTH mission! And still going strong!

During the past year the world famous rover discovered “more extensive aqueous alteration within fractures and more mild alteration within the bedrock outcrops” at Endeavour crater, Arvidson elaborated.

And now she is headed to her next target – an ancient water carved gully!

The gully is situated about 0. 6 mile (1.6 km) south of the robots current location.

But to get there she first has to heroically ascend steep rocky slopes inclined over 20 degrees along the eroded craters western rim – and it’s no easy task! Slipping and sliding along the way and all alone on difficult alien terrain.

Furthermore she is 51 times beyond her “warrantied” life expectancy of merely 90 Sols promised at the time of landing so long ago – roving the surface of the 4th rock from the Sun during her latest extended mission; EM #10.

How was this incredible accomplishment achieved?

“Simply a well-made and thoroughly tested American vehicle,” Arvidson responded.

The six wheeled rover landed on Mars on January 24, 2004 PST on the alien Martian plains at Meridiani Planum -as the second half of a stupendous sister act.

Her twin sister Spirit, had successfully touched down 3 weeks earlier on January 3, 2004 inside 100-mile-wide Gusev crater and survived more than six years.

Opportunity concluded 2016 and starts 2017 marching relentlessly towards an ancient water carved gully along the eroded rim of vast Endeavour crater – the next science target on her heroic journey traversing across never before seen Red Planet terrains.

Huge Endeavour crater spans some 22 kilometers (14 miles) in diameter.

Throughout 2016 Opportunity was investigating the ancient, weathered slopes around the Marathon Valley location in Endeavour crater. The area became a top priority science destination after the slopes were found to hold a motherlode of ‘smectite’ clay minerals based on data from the CRISM spectrometer circling overhead aboard a NASA Mars orbiter.

The smectites were discovered via extensive, specially targeted Mars orbital measurements gathered by the CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.

Opportunity was descending down Marathon Valley the past year to investigate the clay minerals formed in water. They are key to helping determine the habitability of the Red Planet when it was warmer and wetter billions of years ago.

What did Opportunity accomplish scientifically at Marathon Valley during 2016?

“Key here is the more extensive aqueous alteration within fractures and more mild alteration within the bedrock outcrops,” Arvidson explained to me.

“Fractures have red pebbles enhanced in Al and Si (likely by leaching out more soluble elements), hematite, and in the case of our scuffed fracture, enhanced sulfate content with likely Mg sulfates and other phases. Also the bedrock is enriched in Mg and S relative to other Shoemaker rocks and these rocks are the smectite carrier as observed from CRISM ATO data.”

Marathon Valley measures about 300 yards or meters long. It cuts downhill through the west rim of Endeavour crater from west to east – the same direction in which Opportunity drove downhill from a mountain summit area atop the crater rim.

Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011. Endeavour crater was formed when it was carved out of the Red Planet by a huge meteor impact billions of years ago.

“Endeavour crater dates from the earliest Martian geologic history, a time when water was abundant and erosion was relatively rapid and somewhat Earth-like,” explains Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science.

Opportunity has been climbing up very steep and challenging slopes to reach the top of the crater rim. Then she will drive south to Cape Byron and the gully system.

“We have had some mobility issues climbing steep, rocky slopes. Lots of slipping and skidding, but evaluating the performance of the rover on steep, rocky and soil-covered slopes was one of the approved extended mission objectives,” Arvidson explained.

“We are heading out of Cape Tribulation, driving uphill to the southwest to reach the Meridiani plains and then to drive to the western side of Cape Byron to the head of a gully system.”

What’s ahead for 2017? What’s the importance of exploring the gully?

“Finish up work on Cape Tribulation, traverse to the head of the gully system and head downhill into one or more of the gullies to characterize the morphology and search for evidence of deposits,” Arvidson elaborated.

“Hopefully test among dry mass movements, debris flow, and fluvial processes for gully formation. The importance is that this will be the first time we will acquire ground truth on a gully system that just might be formed by fluvial processes. Will search for cross bedding, gravel beds, fining or coarsening upward sequences, etc., to test among hypotheses.”

How long will it take to reach the gully?

“Months to the gully,” replied Arvidson. After arriving at the top of the crater rim, the rover will actually drive part of the way on the Martian plains again during the southward trek to the gully.

“And we will be driving on the plains to drive relatively long distances with an intent of getting to the gully well before the winter season.”

As of today, Jan 31, 2017, long lived Opportunity has survived 4630 Sols (or Martian days) roving the harsh environment of the Red Planet.

Opportunity has taken over 216,700 images and traversed over 27.26 miles (43.87 kilometers) – more than a marathon.

See our updated route map below. It shows the context of the rovers over 13 year long traverse spanning more than the 26 mile distance of a Marathon runners race.

The rover surpassed the 27 mile mark milestone on November 6, 2016 (Sol 4546).

The power output from solar array energy production is currently 416 watt-hours, before heading into another southern hemisphere Martian winter in 2017. It will count as Opportunities 8th winter on Mars.

Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the lower sedimentary layers at the base of Mount Sharp.

On the brink of 4600 Sols of a profoundly impactful life, NASA’s long lived Opportunity rover celebrates the Christmas/New Year’s holiday season on Mars marching relentlessly towards an ancient water carved gully along the eroded rim of vast Endeavour crater – the next science target on her heroic journey traversing across never before seen Red Planet terrains.

“Opportunity is continuing its great 21st century natural history expedition on Mars, exploring the complex geology and record of past climate here on the rim of the 22-km Endeavour impact crater,” writes Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in a mission update.

Indeed, New Years Day 2017 equates to 4600 Sols, or Martian Days – of boundless exploration and epic discovery by the longest living Martian rover ever dispatched by humanity to survey the most Earth-like planet in our solar system.

One can easily imagine our beloved Princess Leia gazing quite proudly upon the feistiness and resourcefulness of this never-give-up Martian Princess rover – climbing steeply uphill no less – nearly 13 YEARS into her 3 MONTH mission!!

“Not a boring flat terrain, but heroically rugged terrain,” says Crumpler.

“Hopefully the brakes are good! For a rover that originally landed 12 years ago on what amounts to a flat parking lot, the current terrain is about as different and rugged as any mountain goat rover could handle.”

Indeed she is 51 times beyond her “warrantied” life expectancy of merely 90 Sols roving the surface of the 4th rock from the Sun during her latest extended mission. (And this time round, the clueless Washington bean counters did not even dare threaten to shut her down – lest they suffer the wrath of a light saber or sister Curiosity’s laser canon !!).

Check out the glorious view from Opportunity’s current Martian holiday season exploits in our newest photo mosaics created by the imaging team of Ken Kremer and Marco Di Lorenzo.

“Opportunity has begun the ascent of the steep slopes here in the inner wall of Endeavour impact crater after completion of a survey of outcrops close to the crater floor. The goal now is to climb back to the rim where the terrain is less hazardous, drive south quickly about 1 km south, and arrive at the next major mission target on the rim before the next Martian winter,” Crumpler elaborated.

After surviving the scorching ‘6 minutes of Terror’ plummet through the thin Martian atmosphere, Opportunity bounced to an airbag cushioned landing on the plains of Meridiani Planum on January 24, 2004 – nearly 13 years ago!

Opportunity was launched on a Delta II rocket from Cape Canaveral Air Force Station in Florida on July 7, 2003.

The newest 2 year extended mission phase just began on Oct. 1, 2016 as the six wheeled robot was stationed at the western rim of Endeavour crater at the bottom of Marathon Valley at a spot called “Bitterroot Valley” and completing investigation of nearby “Spirit Mound.”

She is now ascending back up to the top of the crater rim for the southward trek to ‘the gully’ in 2017.

“Opportunity is making progress towards the next science objective of the extended mission,” researchers leading the Mars Exploration Rover (MER) Opportunity mission wrote in a status update.

“The rover is headed toward an ancient water-carved gully about a kilometer south of the rover’s current location on the rim of Endeavour Crater.”

Endeavour crater spans some 22 kilometers (14 miles) in diameter.

Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011. Endeavour crater was formed when it was carved out of the Red Planet by a huge meteor impact billions of years ago.

“Endeavour crater dates from the earliest Martian geologic history, a time when water was abundant and erosion was relatively rapid and somewhat Earth-like,” Crumpler explains.

“So in addition to exploring the geology of a large crater, a type of feature that no one has ever explored in its preserved state, the mission seeks to take a close look at the evidence in the rocks for the past environment. Thus we are trying to stick to the crater rim where the oldest rocks are.”

But the crater slopes ahead are steep! As much as 20 degrees and more – and thus potentially dangerous! So the team is commanding Opportunity to proceed ahead with caution to “the gully” which is the primary target of her latest extended mission.

The rover has even done “quite a bit of exploratory driving in an effort to attain a good vantage point for finding a path through a troubling area of boulder patch and steep slopes ahead. The concern was whether the available routes to avoid the boulders were all too steep to traverse, in which case we would have to forgo the current ‘Extended Mission 10’ (EM10) route and backtrack to find a different route to our main objective, the ‘gully.’”

“The slopes here exceed 20 degrees and the surface consists of flat outcrops of impact breccias covered with tiny rocks that act like ball bearings,” Crumpler writes. “Anyone who has attempted to walk on a 20 degree slope with a covering of fine pebbles on hard outcrop can attest to the difficulty. Opportunity has been operating at these extreme slope for several months. But going down hill is one thing, And going back up hill is another entirely.”

As of today, Sol 4598, Dec. 29, 2016, Opportunity has taken over 215,900 images and traversed over 27.12 miles (43.65 kilometers) – more than a marathon.

See our updated route map below.

The rover surpassed the 27 mile mark milestone early last month on November 6 (Sol 4546).

The power output from solar array energy production is currently 414 watt-hours, before heading into another southern hemisphere Martian winter in 2017.

Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the lower sedimentary layers at the base of Mount Sharp.

Here’s What Happens When NASA Engineers Carve Their Pumpkins

Every workplace should have this much fun! A group of engineers at the Jet Propulsion Laboratory held their sixth annual pumpkin carving contest, and this year’s entries did not disappoint. Using a combination of engineering savvy and creative license, the JPL engineers carved up several different types of themed pumpkins, including a cow abduction by aliens, a geyser-spewing Europa, unique depictions of several different space missions and much more.

Halloween is actually a special holiday at JPL because October 31, 1936 was the beginning of JPL’s history, when several grad students studying at Caltech and some amateur rocket enthusiasts drove out to a dry canyon tested out a liquid rocket engine. To celebrate JPL’s 80th anniversiary, here’s a link to a gallery of images pairs that shows vintage views from JPL’s history with images that show what the lab looks like today.

In addition, JPL held a Halloween costume contest that really was out of this world. See all the fun below:

This pumpkin was turned into a spooky alien abduction scene:

The longest living Martian rover ever – Opportunity – has just surpassed another unfathomable milestone – 4500 Sols (or days) exploring the Red Planet !! That’s 50 times beyond her “warrantied” life expectancy of merely 90 Sols.

And as we are fond of reporting – the best is yet to come. After experiencing 4500 Martian sunsets, Opportunity has been granted another mission extension and she is being targeted to drive to an ancient gully where life giving liquid water almost certainly once flowed on our solar systems most Earth-like planet.

See Opportunity’s current location around ‘Spirit Mound” – illustrated in our new photo mosaic panoramas above and below.

After a scorching ‘6 minutes of Terror’ plummet through the thin Martian atmosphere, Opportunity bounced to an airbag cushioned landing on the plains of Meridiani Planum on January 24, 2004 – nearly 13 years ago!

Opportunity was launched on a Delta II rocket from Cape Canaveral Air Force Station in Florida on July 7, 2003.

“We have now exceeded the prime-mission duration by a factor of 50,” noted Opportunity Project Manager John Callas of NASA’s Jet Propulsion Laboratory, Pasadena, California.

“Milestones like this are reminders of the historic achievements made possible by the dedicated people entrusted to build and operate this national asset for exploring Mars.”

The newest 2 year extended mission phase just began on Oct. 1 as the rover was stationed at the western rim of Endeavour crater at the bottom of Marathon Valley at a spot called “Bitterroot Valley.”

And at this moment, as Opportunity reached and surpassed the 4500 Sol milestone, she is investing an majestic spot dubbed “Spirit Mound” – and named after her twin sister “Spirit” – who landed 3 weeks earlier!

Endeavour crater spans some 22 kilometers (14 miles) in diameter. Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011.

Endeavour crater was formed when it was carved out of the Red Planet by a huge meteor impact billions of years ago.

But now for the first time she will explore the craters interior, after spending 5 years investigating the exterior and climbing to a summit on the rim and spending several year exploring the top before finally descending down the Marathon Valley feature to investigate clay minerals formed in water.

“The longest-active rover on Mars also will, for the first time, visit the interior of the crater it has worked beside for the last five years,” said NASA officials.

Marathon Valley measures about 300 yards or meters long. It cuts downhill through the west rim of Endeavour crater from west to east – the same direction in which Opportunity drove downhill from a mountain summit area atop the crater rim. See our route map below showing the context of the rovers over dozen year long traverse spanning more than the 26 mile distance of a Marathon runners race.

Opportunity is now being targeted to explore a gully carved out by water.

“We are confident this is a fluid-carved gully, and that water was involved,” said Opportunity Principal Investigator Steve Squyres of Cornell University, Ithaca, New York.

“Fluid-carved gullies on Mars have been seen from orbit since the 1970s, but none had been examined up close on the surface before. One of the three main objectives of our new mission extension is to investigate this gully. We hope to learn whether the fluid was a debris flow, with lots of rubble lubricated by water, or a flow with mostly water and less other material.”

Furthermore, in what’s a very exciting announcement the team “intends to drive Opportunity down the full length of the gully, onto the crater floor” – if the rover continues to function well during the two year extended mission which will have to include enduring her 8th frigid Martian winter in 2017.

And as is always the case, scientists will compare these interior crater rocks to those on the exterior for clues into the evolution, environmental and climatic history of Mars over billions of years.

“We may find that the sulfate-rich rocks we’ve seen outside the crater are not the same inside,” Squyres said. “We believe these sulfate-rich rocks formed from a water-related process, and water flows downhill. The watery environment deep inside the crater may have been different from outside on the plain — maybe different timing, maybe different chemistry.”

As of today, Sol 4522, Oct 12, 2016, Opportunity has taken over 214,400 images and traversed over 26.99 miles (43.44 kilometers) – more than a marathon.

The power output from solar array energy production is currently 472 watt-hours, before heading into another southern hemisphere Martian winter in 2017.

Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the basal layers at the base of Mount Sharp.
