NASA’s mega Mars rover Curiosity is celebrating 1 Year on the Red Planet since the dramatic landing on Aug. 6, 2012 by reveling in a string of groundbreaking science discoveries demonstrating that Mars could once have supported past life – thereby accomplishing her primary science goal – and with a promise that the best is yet to come!

“We now know Mars offered favorable conditions for microbial life billions of years ago,” said the mission’s project scientist, John Grotzinger of the California Institute of Technology in Pasadena.

“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.

Curiosity is now speeding onwards towards Mount Sharp, the huge 3.4 mile (5. 5 km) mountain dominating the center of her Gale Crater landing site – and which is the primary destination of the mission.

During Year 1, Curiosity has transmitted over 190 gigabits of data, captured more than 71,000 images, fired over 75,000 laser shots to investigate the composition of rocks and soil and drilled into two rocks for sample analysis by the pair of state-of-the-art miniaturized chemistry labs housed in her belly – SAM & CheMin.

“From the sophisticated instruments on Curiosity the data tells us that this region could have been habitable in Mars’ distant past,” Green told me.

“This is a major step forward in understanding the history and evolution of Mars.”

And just in the nick of time for her 1 year anniversary, the car sized robot just passed the 1 mile (1.6 kilometer) driving mark on Aug. 1, or Sol 351.

Mount Sharp still lies roughly 5 miles (8 kilometers) distant – as the Martian crow flies.

“We will be on a general heading of southwest to Mount Sharp,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview. See the NASA JPL route maps below.

“We have been going through various options of different planned routes.”

How long will the journey to Mount Sharp take?

“Perhaps about a year,” Erickson told me.

“We have put some new software – called autonav, or autonomous navigation – on the vehicle right after the conjunction period back in March 2013. This will increase our ability to drive.”

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars.

“We are trying to make that significantly faster by bringing the new autonav online. That will help. But how much it helps really depends on the terrain.”

So far the terrain has not been problematical.

“Things are going very well and we have a couple of drives under our belt,” said Erickson, since starting the long trek to Mount Sharp about a month ago.

The lower reaches of Mount Sharp are comprised of exposed geological layers of sedimentary materials that formed eons ago when Mars was warmer and wetter, and much more hospitable to microscopic life.

“It has been gratifying to succeed, but that has also whetted our appetites to learn more,” says Grotzinger. “We hope those enticing layers at Mount Sharp will preserve a broad diversity of other environmental conditions that could have affected habitability.”

Indeed, Curiosity’s breakthrough discovery that the surface of Mars possesses the key chemical ingredients required to sustain microbial life in a habitable zone, has emboldened NASA to start mapping out the future of Mars exploration.

NASA announced plans to start work on a follow on robotic explorer launching in 2020 and develop strategies for returning Martian samples to Earth and dispatching eventual human missions to Mars in the 2030’s using the new Orion capsule and SLS Heavy lift rocket.

“NASA’s Mars program is back on track with the 2016 InSight lander and the 2020 rover,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today in an interview.

“Successes of our Curiosity — that dramatic touchdown a year ago and the science findings since then — advance us toward further exploration, including sending humans to an asteroid and Mars,” said NASA Administrator Charles Bolden in a statement.

“Wheel tracks now, will lead to boot prints later.”

Following the hair-raising touchdown using with the never before used sky-crane descent thrusters, the science team directed the 1 ton robot to drive to a nearby area of interesting outcrops on the Gale crater floor – at a place called Glenelg and Yellowknife Bay.

Along the way, barely 5 weeks after landing, Curiosity found a spot laden with rounded pebbles at the Hottah outcrop of concretions that formed in an ancient stream bed where hip deep liquid water once flowed rather vigorously.

In February 2013, Curiosity conducted the historic first ever interplanetary drilling into Red Planet rocks at the ‘John Klein’ outcrop inside Yellowknife Bay that was shot through with hydrated mineral veins of gypsum.

The Yellowknife Bay basin looks like a dried up river bed.

Analysis of pulverized portions of the gray colored rocky powder cored from the interior of ‘John Klein’ revealed evidence for phyllosilicates clay minerals that typically form in pH neutral water. These starting findings on the crater floor were unexpected and revealed habitable environmental conditions on Mars – thus fulfilling the primary science goal of the mission.

“We have found a habitable environment [at John Klein] which is so benign and supportive of life that probably if this water was around, and you had been on the planet, you would have been able to drink it,” says Grotzinger, summing up the mission.

On the long road to Mount Sharp, Curiosity will make occasional stops for science.

This past week she captured rare sky watching images of the diminutive Martian moons – Phobos and Deimos – together!

Meanwhile, Curiosity’s 10 year old sister rover Opportunity Is trundling merrily along and will arrive shortly at her own mountain climbing goal on the opposite of Mars.

And NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), has just arrived intact at the Kennedy Space Center after a cross country trip aboard a USAF C-17.

Technicians at Kennedy will complete final preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from the Florida Space Coast atop an Atlas V rocket.

On Tuesday, Aug 6, NASA will broadcast a half day of new programming on NASA TV commemorating the landing and discussing the science accomplished so far and what’s coming next.

And stay tuned for more astonishing discoveries during ‘Year 2’ on the Red Planet from our intrepid rover Curiosity – Starting Right Now !

MAVEN is NASA’s next mission to Mars and in less than three days time the spacecraft ships out on a cross country trek for the first step on the long sojourn to the Red Planet.

But before all that, technicians took MAVEN for a final spin test, flexed her solar arrays and bombarded her with sound and a whole lot more.

On Aug. 2, MAVEN (Mars Atmosphere and Volatile EvolutioN Mission) journeys half a continent from its assembly facility at Lockheed Martin in Littleton, Colorado to the Kennedy Space Center and the Florida Space Coast aboard a USAF C-17.

Unlike Curiosity, which is roving across a crater floor on the Red Planet at this very moment, MAVEN is an orbiter with a first of its kind mission.

MAVEN is the first spacecraft from Earth devoted to investigating and understanding the upper atmosphere of Mars.

The goal is determining how and why Mars lost virtually all of its atmosphere billions of years ago, what effect that had on the climate and where did the atmosphere and water go?

To ensure that MAVEN is ready for launch, technicians have been busy this year with final tests of the integrated spacecraft.

Check out this video of MAVEN’s Dry Spin Balance Test

The spin balance test was conducted on the unfueled spacecraft on July 9, 2013 at Lockheed Martin Space Systems in Littleton, Colorado.

NASA says the purpose of the test “is to ensure that the fully integrated spacecraft is correctly balanced and to determine the current center of gravity. It allows the engineering team to fine-tune any necessary weight adjustments to precisely fix the center of gravity where they want it, so that it will perform as expected during the cruise to Mars.”

It was the last test to be completed on the integrated spacecraft before its shipment to Florida later this week.

This next video shows deployment tests of the two “gull-wing” solar panels at Lockheed Martin Space Systems.

Wingtip to wingtip, MAVEN measures 11.43 m (37.5 feet) in length.

In mid May, MAVEN was moved into a Thermal Vacuum Chamber at Lockheed Martin for 19 days of testing.

The TVAC test exposed MAVEN to the utterly harsh temperatures and rigors of space similar to those it will experience during its launch, cruise, and mission at Mars.

MAVEN is slated to blast off atop an Atlas V-401 rocket from Cape Canaveral Air Force Station, Florida on Nov. 18, 2013. The 2000 pound (900 kg) spacecraft will be housed inside a 4 meter payload fairing.

After a 10 month interplanetary voyage it will join NASA’s armada of four robotic spacecraft when it arrives in Mars orbit in September 2014.

Scientists hope that measurements from MAVEN will help answer critical questions like whether, when and how long the Martian atmosphere was once substantial enough to sustain liquid water on its surface and support life.

“What we’re doing is measuring the composition of the atmosphere as a measure of latitude, longitude, time of day and solar activities,” said Paul Mahaffy, of NASA’s Goddard Space Flight Center in Greenbelt, Md, and the principal investigator for MAVEN’s mass spectrometer instrument.

“We’re trying to understand over billions of years how the atmosphere has been lost.”

Exactly a decade after blasting off for the Red Planet and discovering a wide swath of water altered rocks and minerals in the ensuing years by exploring countless craters large and small, NASA’s intrepid Opportunity rover is just days away from arriving at her next big quest – a Martian mountain named Solander Point that may possess the key chemical ingredients necessary to sustain Martian life forms.

“We are parked 200 meters away from the bench at Solander Point,” Ray Arvidson told Universe Today exclusively. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo. Furthermore, this area exhibits signatures related to water flow.

Solander Point also represents ‘something completely different’ – the first mountain the intrepid robot will ever climb.

“This will be Opportunity’s first mountain and the view from the ridge crest should be spectacular,” wrote Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in his latest field report about the 10 years ongoing Mars Exploration Rover (MER) mission.

Indeed the rover is now just a few short drives southward from making landfall on the northern tip of the point in her current trek across the relatively flat plains around the rim of Endeavour crater.

“We are now only about 180 meters from the new mountain, Solander Point.”

But before moving onward, Arvidson explained that the rover will briefly pause here “at dark terrain” for some exciting science due to water related spectral observations from the CRISM instrument captured by NASA’s Mars Reconnaissance Orbiter (MRO) circling overhead.

“CRISM data [from Mars orbit] shows a relatively deep 1.9 micrometer absorption feature due to H2O-bearing minerals,” said Arvidson.

This past spring, Opportunity made the historic discovery of clay minerals and a habitable environment on a low hill called Cape York at the rover’s prior stop along the rim of Endeavour crater.

Solander was selected as the robot’s next destination because it simultaneously offers a goldmine of science as well as north facing slopes – where Opportunity’s solar wings can more effectively soak up the sun’s rays to generate life giving electrical power during the next Martian winter.

But since Opportunity is currently generating plenty of power from her solar arrays and arriving with a bonus cushion of time before the looming onset of her 6th Martian winter, the team decided to take a small detour to the southeast and spend several sols (or Martian days) exploring an area of intriguing geology of outcrops, gypsum signatures and more on the bench surrounding the base of the mountain.

“We slowed down this week so that we could check out the rocks here where there is a strange hydration signature from orbital remote sensing,” says Crumpler.

“This is also an area that appears to have more large blocks in the HiRISE images [from Mars orbit], so we are checking out one of the blocks, “Black Shoulder”.

“We are hoping that the rocks on the ridge crest will be spectacular too,” notes Crumpler.

Opportunity is using the science instruments on her 3 foot ( 1 meter) long robotic arm to conduct brief in-situ investigations of “Black Shoulder” with the Microscopic Imager (MI) and the Alpha Particle X-ray Spectrometer (APXS).

And …. it’s ‘Mountains Galore’ from here on out for the remainder of Opportunity’s Magnificent Mission to Mars.

Why? Because Opportunity is nearing the foothills of a long chain of eroded segments of the crater wall of Endeavour crater which spans a humongous 14 miles (22 kilometers) wide.

Solander Point may harbor deposits of phyllosilicate clay minerals – which form in neutral pH water – in a thick layer of rock stacks indicative of a past Martian habitable zone.

The rover team is discussing the best way to approach and drive up Solander.

“One idea is to drive part way up Solander from the west side of the rim, turn left and then drive down the steeper north facing slopes with the stratographic sections,” Ray Arvidson explained to Universe Today.

“That way we don’t have to drive up the relatively steeper slopes.”

“The rover can drive up rocky surfaces inclined about 12 to 15 degrees.”

“We want to go through the stratographic sections on the north facing sections,” Arvidson told me.

Today (July 28) is Sol 3380 for a mission that was only warrantied to last 90 Sols!

Opportunity’s total driving distance exceeds 23.6 miles (37.9 kilometers). She has snapped over 182,000 images.

Meanwhile on the opposite side of Mars at Gale Crater, Opportunity’s younger sister rover Curiosity also discovered a habitable environment originating from a time when the Red Planet was far warmer and wetter billions of years ago.

And like Opportunity, Curiosity is also trekking towards a mountain rich in sedimentary layers hoping to unveil the mysteries of Mars past. But Curiosity likely won’t arrive at 3.4 mile (5.5 km) high Mount Sharp for another year.

Curiosity Sets Record Pace for Longest Drive Yet on Mars

The scene taken on Sol 340 was taken shortly after Curiosity finished her longest yet. The 329.1-foot (100.3-meter) drive was twice as long as any previous sol's drive by Curiosity. The view is toward the south, including a portion of Mount Sharp and a band of dark dunes in front of the mountain. The Mars Hand Lens Imager (MAHLI) camera on NASA's Curiosity rover is carried at an angle when the rover's arm is stowed for driving. Still, the camera is able to record views of the terrain Curiosity is crossing in Gale Crater, and rotating the image 150 degrees provides this right-side-up scene. Credit: NASA/JPL-Caltech/MSSS

NASA’s car-sized Curiosity rover is now blazing across the Red Planet’s surface and moving at a record setting pace towards a towering Martian mountain loaded with mineral caches that could potentially support a habitable environment.

On Sunday, July 21 (or Sol 340), Curiosity drove the length of a football field – 109.7 yards (100.3 meters) – a span that’s twice as far as she had ever driven before since the dramatic touch down on Mars nearly a year ago.

The previous record for a one-day drive was about half a football field – 54 yards (49 meters) – and achieved on Sol 50 (Sept. 26, 2012), roughly seven weeks after the pulse pounding landing inside Gale Crater on Aug. 6, 2012.

The 6 wheeled robot was able to move so far because on the prior drive she wound up atop a rise offering an uncommonly good view of the surrounding landscape and the road ahead across the crater floor towards Mount Sharp – the ultimate driving goal.

“What enabled us to drive so far on Sol 340 was starting at a high point and also having Mastcam images giving us the size of rocks so we could be sure they were not hazards,” said rover planner Paolo Bellutta of NASA’s Jet Propulsion Laboratory, Pasadena, Calif, in a NASA statement.

“We could see for quite a distance, but there was an area straight ahead that was not clearly visible, so we had to find a path around that area.”

Following another lengthy drive of 68.2 yards (62.4 meters) on Wednesday, July 23 (Sol 342), the mission’s total driving distance so far stands at 0.81 mile (1.23 kilometers).

Mount Sharp lies about 5 miles (8 kilometers) distant – as the Martian crow flies.

On July 4, Curiosity embarked on the epic trek to Mount Sharp after completing more than seven months of science investigations and historic interplanetary drilling and sample analysis at an area known as Glenelg and Yellowknife Bay. There she discovered a habitable environment with the chemical ingredients that could sustain Martian microbes- thereby already accomplishing the primary goal of NASA’s flagship mission to Mars.

A combination of increased experience by the engineers directing the mega rover as well as intermediate software upgrades also play key roles in speeding Curiosity towards 3.4 mile (5.5 km) high Mount Sharp.

A huge leap in roving across Mars is in the works soon using new driving software called autonomous navigation, or autonav, that will hasten the overland journey.

“We have put some new software – called autonav, or autonomous navigation – on the vehicle right after the conjunction period back in March 2013,” said Jim Erickson, Curiosity Project Manager, in exclusive interview with Universe Today. Erickson is from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

“This will increase our ability to drive.”

Implementing the new driving software will make Curiosity smarter as well as more capable, productive and independent than ever before.

“With autonav the rover will have the ability to understand how far it’s driving, whether its slipping or not, and it improves safety,” Erickson told me.

The rover’s route is on a southwestward heading towards the ancient sedimentary layers at the foothills of the mountain in the middle of Gale Crater.

In addition to setting new driving records, the 1 ton rover is also driving more frequently and on repeated days too.

When everything synchs up, Curiosity can drive two or more days in row.

“We can drive two days in a row now if the timing is right. If we get the results of the day’s drive (n) in time before we have to plan the next day’s drive (n+1) – almost as if you’re on Mars time. Then that would work fine,” Erickson explained.

“Also, when we get the autonav capability we can plan two days in row. One day of directed driving and the second day can be ‘OK here’s your target from wherever you end up, try and go to this spot’.”

“This will increase the productivity!”

Erickson says the team is testing autonav now and should it be up and running within weeks, or sooner.

Read Part 1 & Part 2 of my interview with Jim Erickson for further details.

Meanwhile Curiosity’s older sister rover Opportunity is making fast tracks towards her own mountain goal and should arrive at the base of Solander Point rather soon in August.

Solander Point is a segment of the eroded rim of huge Endeavour crater and may also possess key ingredients essential to support an environment favorable for possible Martian microbes.

And it’s worth noting that older sis Opportunity stills holds the 1 day Martian distance driving world record of 219.89 meters – established more than 8 years ago on Sol 410 (March 20, 2005)!!

Stay tuned for more on NASA’s sojourning pair of Martian robots.

NASA’s state-of-the-art Curiosity Mars rover is stepping up the driving pace and rolling relentlessly across alien Martian terrain towards the towering mystery mountain known as Mount Sharp that’s holds the keys to the Red Planets past evolution and whether its an abode for Life.

To uncover the latest scoop on the robots otherworldly adventures, Universe Today conducted an exclusive interview with the Curiosity Project Manager Jim Erickson, of NASA’s Jet Propulsion Laboratory (JPL).

In Part 2 of my conversation with Jim Erickson we’ll discuss more about the rover’s traverse across alien territory that’s simultaneously a science gold mine and a potential death trap, as well as Comet ISON and nighttime observations and science planning.

Read Part 1 – here.

“When Comet ISON is in the sky I’m sure we’ll do some observations of it depending on when its visible,” Erickson told me.

Today, July 20, is Sol 339 of the rovers mission to Mars. And also the 44th anniversary of the 1st human Moonwalks in 1969.

And Curiosity just drove another 34 meters yesterday, Sol 338 (July 19) – for a total distance exceeding 1.1 kilometers.

Curiosity's Traverse Map Through Sol 338 This map shows the route driven by NASA's Mars rover Curiosity through Sol 338 of the rover's mission on Mars (July 19, 2013). Numbering of the dots along the line indicate the sol number of each drive. North is up. The scale bar is 200 meters (656 feet). From Sol 337 to Sol 338, Curiosity had driven a straight line distance of about 122.90 feet (32.59 meters).

As for Martian sand dunes, they dunes offer both exciting opportunities and lurking dangers to the rovers well being.

Indeed fields of Martian sand dunes are potential death traps and the six wheeled rover has no choice but to traverse across an extensive dune field as she closes in on the base of Mount Sharp

Recall that NASA’s now long lived Opportunity rover nearly perished rather early in her mission at the ‘Purgatory’ dune field on Meridiani Planum.

Spirit died after more than six highly productive years on the Red Planet when she was unable to escape a hidden sand trap she had accidentally fallen wheels deep into as the vehicle was merrily roving beside an eroded volcano at Gusev Crater on the approach to the mysterious Von Braun mound.

So, dunes are serious business

Here is Part 2 of my interview with Jim Erickson.

Ken Kremer: Which direction is Curiosity headed? Will she be following the southwest route shown in the ellipse on the JPL map – see traverse map below – or reinvestigate any other spots nearer the landing site first?

Jim Erickson: We have a good general idea. We will be on a general heading of southwest, not west which would have taken us back near the landing site [at Bradbury Landing].

Ken: So the rover will not pass by the Hottah outcrop of concretions formed in water and investigated early in the mission?

Jim Erickson: No. The intent for the ellipse [shown on the map] is that we will be traveling in it to get to an area where the sand dunes look better for crossing [to the base of Mount Sharp]. When we get there we will know reality. And we will pick a safe spot to cross.

The dunes can be both an issue or in some cases easy sailing.

My experience on MER [Spirit & Opportunity] was that when you are going with the dunes, down a trough, they tend to be well packed and that was great driving.

But if you need to make a right turn, that can be a challenge for a couple of reasons. It is harder to see what is inside the next trough. And you have to drive to the top of the dune. So your driving is limited until you can see what’s inside the next dune.

Level ground is more straightforward. You know exactly what to look for if the terrain doesn’t change the next day. So you can do the same thing you did last night based on the new set of images.

If the terrain is changing then it gets more complicated.

Ken: Will you be straddling the dunes or driving alongside some safe distance away?

Jim Erickson: We have been going through various options of different planned routes. At some point we have to go with the dune directions.

So we’ll be traveling down some troughs later on. We will definitely have to pick our way through them.

Part of it is gaining experience in this new area of Mars with how the sand dunes and troughs themselves actually are.

So we’ll have to wait and see. We know we’ll have to deal with the dunes. Depending on how these dunes act we may have to do different things compared to MER.

Ken: What’s the health status of Curiosity?

Jim Erickson: We’re doing great. There are always active things we are looking at.

We had the anomaly before conjunction and have put in place a number of software mitigations and reconfigured the A side memory so that we can work around the hardware problem that happened. If we have another problem, both the A and B side memory can handle it gracefully, unlike the last time.

Ken: Describe the rover’s power situation? And the ability to do nighttime observations like the recent imagery of Phobos rising?

Read earlier Phobos story – here

Jim Erickson: Yes. We have plenty of power.

And certainly will be able to do nighttime observations.

Ken: What’s the plan for observations of Comet ISON?

Jim Erickson: When we get to the point when Comet ISON is in the sky I’m sure we’ll do some observations of it, depending on the time period when its visible.

Note: NASA’s Curiosity and Opportunity rovers will have a view of ISON in October with Oct. 1, 2013, being the comet’s closest approach to Mars.

NASA’s Directory of Planetary Science Jim Green told me previously that NASA is very interested in using its orbiting and surface assets at Mars to study Comet ISON. It’s a once in a lifetime opportunity.

Early October 2013 will be the prime viewing time for ISON from the vicinity of the Red Planet.

Let’s hope that NASA’s quartet of spacecraft and ESA’s lone orbiter capture some breathtaking imagery and science observations.

Ken: About the recent Phobos nighttime images, a Universe Today reader asked whether the other points of light beside Phobos were stars or hot pixels?

Jim Erickson: The specks are hot pixels [not stars], intensified by the long exposure times for the image.

Video Caption: ‘Phobos Rising’ – This movie clip shows Phobos, the larger of the two moons of Mars, passing overhead, as observed by Curiosity in a series of images centered straight overhead starting shortly after sunset on June 28, 2013. Phobos first appears near the lower center of the view and moves toward the top of the view. The apparent ring is an imaging artifact. The other bright spots are hot pixels – not stars. Credit: NASA/JPL-Caltech

Ken: How about the prospects for science along the way to the mountain?

Jim Erickson: We expect to do science along the way to Mount Sharp, for example in terms of atmospheric measurements.

We will stop at some preplanned sites. Exactly which ones is still being debated by the scientists.

And we’ll do the right thing – If we see something spectacular along the way. Just because we may not have identified it previously, that doesn’t mean we won’t stop and examine it.

Things are going very well, says Erickson.

Erickson has worked in key positions on many NASA planetary science missions dating back to Viking in the 1970’s. These include the Galileo mission to Jupiter, both MER rovers Spirit & Opportunity, as well as a stint with the Mars Reconnaissance Orbiter (MRO).

I’ll have more upcoming from Jim about Curiosity’s Martian drilling activities.

As of today (July 20) Curiosity has driven nine times since leaving the Glenelg/Yellowknife Bay area on July 4 (Sol 324), totaling nearly 300 meters.

Stay tuned for more from Mars.

NASA’s 2020 Mars Rover To Seek Signs of Past Life and Collect Samples for Earth Return

Artist's Concept of NASA’s Mars 2020 Rover envisions a basic structure that capitalizes on re-using the design and engineering work done for the NASA rover Curiosity, which landed on Mars in 2012, but with new science instruments for accomplishing different science objectives with the 2020 mission. Credit: NASA/JPL-Caltech

NASA’s next Mars rover set for liftoff in 2020 should focus on three primary objectives; seeking signs of past life, collecting a cache of carefully chosen samples for eventual return to Earth and developing technologies that will help enable future human missions to the Red Planet some two decades from now.

The 2020 goals were laid out publicly today (July 9) by a panel of scientists on the ‘Science Definition Team’ and charged by NASA with defining the key science objectives for the new mission.

The science objectives and how to accomplish them are outlined in considerable detail in a newly issued 154 page report handed over to the space agency and discussed at today’s NASA briefing for the media.

Looking for signs of ancient life and preserved biosignatures on Mars at a place that was once habitable is the top priority of the 2020 mission. The SDT report states that the landing site should be chosen specifically to “explore the geology of a once habitable site.”

“We need a highly mobile rover that can make ‘in situ’ science measurements,” said Jack Mustard, chairman of the Science Definition Team and a professor at the Geological Sciences at Brown University in Providence, R.I., at the briefing.

“The rover would use its own instruments on Mars for visual, mineralogical and chemical analysis down to a microscopic scale to identify candidate features that may have been formed by past life,” states the SDT report.

“We can’t do this now with Curiosity,” explained Mustard. “We need higher resolution.”

Looking for ‘extant’ life, that is life surviving on Mars today, would be a by-product of the search for organic molecules and preserved biosignatures of life – past or present.

The Mars 2020 ‘Science Definition Team’ (SDT) is comprised of 19 scientists and engineers from academia and industry. They were appointed by NASA in January 2013 to thoroughly and quickly evaluate a wide range of options to accomplish the highest priority planetary science objectives and achieve President Obama’s challenge to send humans to Mars in the 2030s.

Retrieving soil and rock samples from Mars for analysis back on Earth by research teams worldwide using all the most advanced analytical instruments available to humankind with unprecedented capability has been the ‘Holy Grail’ of Mars exploration for several decades.

But the enormous cost and technical complexity of a Mars Sample Return (MSR) mission has caused it to be repeatedly postponed.

Creating a Returnable Cache of Martian Samples is a major objective for NASA's Mars 2020 rover. This prototype show hardware to cache samples of cores drilled from Martian rocks for possible future return to Earth. The 2020 rover would be to collect and package a carefully selected set of up to 31 samples in a cache that could be returned to Earth by a later mission. The capabilities of laboratories on Earth for detailed examination of cores drilled from Martian rocks would far exceed the capabilities of any set of instruments that could feasibly be flown to Mars. The exact hardware design for the 2020 mission is yet to be determined. For scale, the diameter of the core sample shown in the image is 0.4 inch (1 centimeter).

The 2020 rover will be designed to make real progress on sample return for the first time. It will be capable of coring into rocks and storing 31 highly compelling Martian samples for return by a follow on mission to the Red Planet.

“But the timing on actually returning those samples to Earth is yet to be determined,” said John Grunsfeld, NASA’s associate administrator for science in Washington.

Everything NASA does is budget driven and the fiscal climate is rather gloomy right now.

“Crafting the science and exploration goals is a crucial milestone in preparing for our next major Mars mission,” said John Grunsfeld, NASA’s associate administrator for science in Washington, in a statement.

Work on the new rover must begin soon in order to achieve the mandatory 2020 launch deadline. Launch opportunities to Mars only open every 26 months and delays could balloon the costs by several hundred million dollars.

“The objectives determined by NASA with the input from this team will become the basis later this year for soliciting proposals to provide instruments to be part of the science payload on this exciting step in Mars exploration,” adds Grunsfeld.

“The 2020 rover will take a major step in ‘seeking signs of life” said Jim Green, director of NASA’s Planetary Science Division in Washington, at the briefing. “NASA will issue a call for science instruments this fall.”

The new mission would build upon the demonstrated science accomplishments of earlier missions like Curiosity, Spirit, Opportunity and Phoenix while vastly advancing the capabilities of the robots research instruments.

“Here’s the bottom line. Questions drive science,” explained Lindy Elkins-Tanton, SDT member and director of the Carnegie Institution for Science’s Department of Terrestrial Magnetism, Washington.

“We should be seeking to answer the very biggest questions. And one of the very biggest questions for all of humankind is – ‘Are we alone?’ And that is the question we’re hoping to make really big advances with on with this Mars 2020 mission.”

Grunsfeld explained that NASA has budgeted “for a mission cost of $1.5 Billion plus the cost of the launcher.”

The 2020 rover chassis, with some modifications, will be based on the blueprints of the highly successful Curiosity rover to keep down the cost and minimize risks. But the science instruments will be completely new and updated.

NASA’s 1 ton Curiosity rover touched down nearly a year ago and has already discovered that the Red Planet has the chemical ingredients and environmental conditions for a habitable zone that could have supported living Martian microbes.

The next logical step is to look for the ancient signs of life that would be preserved in the rock record on Mars.

Curiosity rover Embarks on Epic Trek To Mount Sharp

NASA’s Curiosity rover has at last begun her epic trek to the layered slopes of mysterious Mount Sharp – the mission’s primary destination which looms supreme inside the Gale Crater landing site.

Scientists expect to discover signatures of the chemical ingredients that potentially are markers for a Martian habitable zone, while climbing up Mount Sharp.

On July 4 (Sol 324), the six wheeled robot started driving away from the Glenelg and Yellowknife Bay areas where she has worked more than half a year investigating the alien terrain and drilling into Martian rocks for the first time in history.

“We have started the long traverse to the base of Mt. Sharp (Aeolis Mons), the long-term goal of the mission!” announced science team member Ken Herkenhoff of the USGS.

So far the NASA rover already driven more than 190 feet (58 meters) over two excursions on July 4 and 7, away from her last science campaign at the Shaler outcrop of cross-bedded, sedimentary outcrops. Another drive is planned today.

Billions of years of Mars geologic history are preserved in the sedimentary layers of Mount Sharp- including the ancient time period when the Red Planet was far wetter and warmer than today, and thus more hospitable to the origin of life.

The huge mountain rises about 3.4 miles (5.5 km) from the center of Gale Crater. Its taller than Mount Ranier in Washington State.

The overland journey could take nearly a year or even longer into 2014 to arrive at the base of Mount Sharp, depending on what the 1 ton behemoth sees along the way.

And the scientists are eager to make as many discoveries as possible.

“The mission is discovery driven,” says John Grotznger of the California Institute of Technology in Pasadena, Calif., who leads NASA’s Curiosity Mars Science Laboratory mission. “We will go to where the science takes us.”

NASA chose Gale Crater as the landing site specifically to dispatch Curiosity to investigate the sedimentary layers of Mount Sharp because in surveys from Mars orbit it exhibited signatures of clay minerals that form in neutral water and that could possibly support the origin and evolution of simple Martian life forms, past or present.

“We have a real desire to get to Mount Sharp because there we see variations in the mineralogy as we go up from the base to higher levels and a change in the record of the environment,” explained Joy Crisp of JPL, Curiosity’s deputy project scientist.

“If we pass something amazing and compelling we might turn around and drive back,” Crisp added.

“The challenge for the science team will be to identify the most important targets along the way, and to study them without delaying drive progress too much,” notes Herkenoff.

Mount Sharp lies about 5 miles (8 kilometers) distant – as the Martian crow flies.

And Curiosity must also pass through a potentially treacherous dune field to get there.

“We are looking for the best path though,” said Curiosity Project Manager Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. at a recent media briefing.

11 months ago on Aug. 6 , 2012, Curiosity made an unprecedented pinpoint touchdown inside Gale Crater using the never before used Sky crane descent thrusters.

Long before even arriving at destination Mount Sharp, Curiosity has already successfully accomplished the key science objective of the mission when she discovered that liquid water flowed at this spot on Mars, it possesses the key chemical ingredients required for life and was habitable in the past.

Drill samples from the ‘John Klein’ outcrop at Yellowknife Bay analyzed by Curiosity’s pair of onboard chemistry labs – SAM & Chemin – revealed that this location contains clay minerals required to support microbial life forms.

Today, NASA’s Opportunity rover marks a magical moment celebrating 10 years since launching to Mars on July 7, 2003 and with her impending Mountain destination filling the camera’s eye view.

The now legendary robot has vastly exceeded everyone’s expectations. Back in 2003 the science team promised us a mere 90 day ‘warranty’ following the suspenseful airbag landing on Jan. 24, 2004 at Meridiani Planum.

Today is Martian Day (or Sol) 3360. That amounts to a life expectancy and exploration ‘bonus’ of more than 37 times beyond the design lifetime.

Opportunity’s twin sister Spirit blasted off three weeks earlier in June 2003 and continued functioning until 2010.

“I never thought we’d achieve nine months!” Principal Investigator Prof. Steve Squyres of Cornell University told me recently on the occasion of the rovers 9th anniversary on Mars in January 2013.

As you read this, the now decade old rover Opportunity is blazing a trail toward’s the oldest geological deposits she has ever explored – at a place called Solander Point, a raised ridge along the eroded rim of huge Endeavour Crater.

Opportunity has surpassed the halfway point in the traverse from the rim segment she has explored the past 22 months at ‘Cape York’ to her next rim segment destination at Solander.

From tip to tip, Cape York and Solander Point lie 1.2-mile (2-kilometer) apart along the western rim of Endeavour Crater. Both are raised portions of 14-mile-wide (22-kilometer-wide) Endeavour.

The rover has less than half a mile (800 meters) to go to finish the Martian dash from one rim segment to the next across an area called ‘Botany Bay’.

This view from July 2, 2013 (Sol 3355) shows the terrain that NASA's Mars Exploration Rover Opportunity is crossing in a flat area called "Botany Bay" on the way toward "Solander Point," which is visible on the horizon.

“We are making very good progress crossing ‘Botany Bay,’ said John Callas of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., who is project manager for the mission now entering its 2nd decade.

The flat terrain of fractured, light-toned bedrock is devoid of treacherous dunes and is easy to drive across, almost like a highway, which simplifies the daily planning by the rovers Earthly handlers.

“The surface that Opportunity is driving across in Botany Bay is polygonally fractured outcrop that is remarkably good for driving,” said Brad Joliff, an Opportunity science team member and long-term planner at Washington University in St. Louis. “The plates of outcrop, like a tiled mosaic pavement, have a thin covering of soil, not enough to form the wind-blown ripples we’ve had to deal with during some other long treks. The outcrop plates are light-toned, and the cracks between them are filled with dark, basaltic soil and our old friends the ‘blueberries.”

The “blueberries” are hematite-rich, erosion-resistant concretions about the size of BB’s that Opportunity discovered when she first opened her eyes at her Eagle crater landing site. During the multi year crater hopping tour that ensued, the rover continued finding patches of blueberries all the way to Endeavour crater.

Opportunity is expected to arrive at Solander’s foothills sometime in August – before the onset of the next southern hemisphere Martian winter, her 6th altogether.

Opportunity will scale Solander to continue the science quest in search of additional evidence of habitable environments with the chemical ingredients necessary to sustain Martian microbial life.

“Right now the rover team is discussing the best way to approach and drive up Solander,” Ray Arvidson told Universe Today. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

‘Solander Point’ offers roughly about a 10 times taller stack of geological layering compared to ‘Cape York.’

Solander also offers north facing slopes where Opportunity’s solar wings can more effectively soak up the sun’s rays to generate life giving electrical power.

The robot remains in excellent health.

The total driving distance exceeds 23 miles (37 kilometers). She has snapped over 181,000 images.

And like Opportunity, Curiosity is also trekking towards a mountain rich in sedimentary layers, hoping to unveil the mysteries of Mars past.

NASA’s nearly decade old Opportunity Mars rover is sailing swiftly on a southerly course towards her first true mountain climbing destination – named “Solander Point” – in search of further evidence of habitable environments with the chemical ingredients necessary to sustain Martian life forms.

At Solander Point, researchers have already spotted deep stacks of ancient rocks transformed by flowing liquid water eons ago. It is located along the western rim of huge Endeavour Crater.

Solander Point may harbor clay minerals in the rock stacks indicative of a past Martian habitable zone.

“One idea is to drive part way up Solander from the west side of the rim, turn left and then drive down the steeper north facing slopes with the stratographic sections,” Arvidson told me.

“That way we don’t have to drive up the relatively steeper slopes. The rover can drive up rocky surfaces inclined about 12 to 15 degrees.”

“We want to go through the stratographic sections on the north facing sections.”

The science team hopes that by scaling Solander, Opportunity will build on her recent historic discovery of a habitable environment at a rock called “Esperance” that possesses a cache of phyllosilicate clay minerals.

These aluminum rich clay minerals typically form in neutral, drinkable water that is not extremely acidic or basic and therefore could support a path to potential Martian microbes.

“Esperance ranks as one of my personal Top 5 discoveries of the mission,” said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for NASA’s rover mission at a recent media briefing.

Using high resolution CRISM spectral data collected from Mars orbit, the rover was specifically directed to Esperance, Arvidson explained. The rock was found about a kilometer back on Matijevic Hill at ‘Cape York’, a rather low hilly segment of the western rim of giant Endeavour crater which spans 14 miles (22 km) across.

‘Solander Point’ offers roughly about a 10 times taller stack of geological layering compared to ‘Cape York.’ Both areas are raised segments of the western rim of Endeavour Crater.

The team is working now to obtain the same type of high resolution spectral evidence for phyllosilicate clay minerals at Solander as they had at Cape York to aid in targeting Opportunity to the most promising outcrops, Arvidson explained.

Opportunity is snapping ever more spectacular imagery of Solander Point and the eroded rim of Endeavour Crater as she approaches closer every passing Sol, or Martian Day. See our original photo mosaics herein by Marco Di Lorenzo and Ken Kremer.

The long lived robot arrived at the edge of Endeavour crater in mid-2011 and will spend her remaining life driving around the scientifically rich crater rim segments.

On June 21, 2013, Opportunity marked five Martian years on Mars since landing on Jan 24, 2004 with a mere 90 day (Sol) ‘warranty’.

This week Opportunity’s total driving distance exceeded 23 miles (37 kilometers).

The solar powered robot remains in excellent health and the life giving solar arrays are producing plenty of electrical power at the moment.

Solander Point also offers northerly tilled slopes that will maximize the power generation during Opportunity’s upcoming 6th Martian winter .

The rover handlers want Opportunity to reach Solander’s slopes by August, before winter’s onset.

As ot today (tosol) Opportunity has trekked about halfway from Cape York to Solander Point – tip to tip.

On the opposite side of Mars at Gale Crater, Opportunity’s younger sister rover Curiosity also discovered clay minerals and a habitable environment originating from a time when the Red Planet was far warmer and wetter billions of years ago.

Spectacular Billion Pixel Panorama from NASA’s Curiosity Mars Rover

This is a cropped, reduced version of panorama from NASA’s Mars rover Curiosity with 1.3 billion pixels in the full-resolution version. See full panorama below. It shows Curiosity at the “Rocknest” site where the rover scooped up samples of windblown dust and sand. Curiosity used three cameras to take the component images on several different days between Oct. 5 and Nov. 16, 2012.

NASA’s newly produced and absolutely spectacular panorama from the Curiosity mega rover offers armchair explorers back on Earth a mammoth 1.3 billion pixels worth of Mars in all its colorful glory.

And everyone can move back and forth around the interactive panorama and zoom in – with special embedded tools- to your hearts delight in exquisite detail at the ‘Rocknest’ site where the rover spent her first extended science stay in late 2012.

This extra special Rocknest panorama is the first NASA- produced view comprising more than a billion pixels from the surface of the Red Planet.

It offers a full 360 degree panoramic view around the rover encompassing breathtaking vistas of Mount Sharp and the eerie rim of Gale Crater, some 20 miles distant.

Mount Sharp rises 3.4 miles (5.5 km) high and is the target destination. The team hopes Curiosity will arrive at the base of Mount Sharp perhaps late this year or early in 2014.

The ‘Rocknest’ scene was assembled from nearly 900 raw images snapped by three different cameras among the 17 total that Curiosity uses as she trundles across the crater floor in search of the ingredients of life.

The panorama was created by Bob Deen of the Multi-Mission Image Processing Laboratory at NASA’s Jet Propulsion Laboratory, Pasadena, Calif, where the mission is managed on a daily basis.

“It gives a sense of place and really shows off the cameras’ capabilities,” said Deen in a statement. “You can see the context and also zoom in to see very fine details.”

“Rocknest” was a windblown ripple of sand dunes that Curiosity drove to after departing from the touchdown site at ‘Bradbury Landing’ and thoroughly investigated in October and November 2012.

It was at ‘Rocknest’ where the six wheeled rover famously deployed her robotic arm to scoop into the Martian dirt for the very first time and then delivered those first grains to the duo of analytical chemistry labs inside her belly that lie at the heart of Curiosity’s science mission.

Deen assembled the color product using 850 raw images from the 100 mm telephoto camera of Curiosity’s Mast Camera instrument, supplemented with 21 more from the Mastcam’s wider-angle 34 mm camera.

In order to take in the rover itself, the view also included 25 black-and-white raw images from the Navigation Camera on the Mast.

All the images were taken between Oct. 5 and Nov. 16, 2012 while the rover was stationary at Rocknest.

Because the images were captured over many days and at different times of day, the lighting and atmospheric clarity varies – especially in distant views to the crater rim.

Since landing on August 6, 2012, Curiosity has already accomplished her primary goal of finding a habitable zone at Gale Crater with an environment that could once of supported Martian microbial life – at the current worksite at ‘Yellowknife Bay.’

The 1 ton robot is equipped with 10 state-of-the-art science instruments with research capabilities that far surpass any prior landed mission and is in the middle of the 2-year primary mission to the Red Planet.

Meanwhile, Curiosity’s older sister rover Opportunity has also discovered clay minerals and a habitable zone on the opposite side of the Red Planet – details here.
