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.

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.

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.

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.

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.

Curiosity’s Martian Chronicles Rife With Intriguing Inconsistencies

The study of Mars’ surface and atmosphere has unlocked some ancient secrets. Thanks to the efforts of the Curiosity rover and other missions, scientists are now aware of the fact that water once flowed on Mars and that the planet had a denser atmosphere. They have also been able to deduce what mechanics led to this atmosphere being depleted, which turned it into the cold, desiccated environment we see there today.

At the same time though, it has led to a rather intriguing paradox. Essentially, Mars is believed to have had warm, flowing water on its surface at a time when the Sun was one-third as warm as it is today. This would require that the Martian atmosphere had ample carbon dioxide in order to keep its surface warm enough. But based on the Curiosity rover’s latest findings, this doesn’t appear to be the case.

These findings were part of an analysis of data taken by the Curiosity’s Chemistry and Mineralogy X-ray Diffraction (CheMin) instrument, which has been used to study the mineral content of drill samples in the Gale Crater. The results of this analysis were recently published in Proceedings of the National Academy of Science, where the research team indicated that no traces of carbonates were found in any samples taken from the ancient lake bed.

To break it down, evidence collected by Curiosity (and a slew of other rovers, landers and orbiters) has led scientists to conclude that roughly 3.5 billion years ago, Mars surface had lakes and flowing rivers. They have also determined, thanks to the many samples taken by Curiosity since it landed in the Gale Crater in 2011, that this geological feature was once a lake bed that gradually became filled with sedimentary deposits.

However, for Mars to have been warm enough for liquid water to exist, its atmosphere would have had to contain a certain amount of carbon dioxide – providing a sufficient Greenhouse Effect to compensate for the Sun’s diminished warmth. Since rock samples in the Gale Crater act as a geological record for what conditions were like billions of years ago, they would surely contain plenty of carbonate minerals if this were the case.

Carbonates are minerals that result from carbon dioxide combining with positively charged ions (like magnesium and iron) in water. Since these ions have been found to be in good supply in samples of Martian rock, and subsequent analysis has shown that conditions never became acidic to the point that the carbonates would have dissolved, there is no apparent reason why they wouldn’t be showing up.

Along with his team, Thomas Bristow – the principal investigator for the CheMin instrument on Curiosity – calculated what the minimum amount of atmospheric carbon dioxide would need to be, and how this would have been indicated by the levels of carbonate found in Martian rocks today. They then sorted through the years worth of the CheMin instrument’s data to see if there were any indications of these minerals.

But as he explained in a recent NASA press release, the findings simply didn’t measure up:

“We’ve been particularly struck with the absence of carbonate minerals in sedimentary rock the rover has examined. It would be really hard to get liquid water even if there were a hundred times more carbon dioxide in the atmosphere than what the mineral evidence in the rock tells us.”

In the end, Bristow and his team could not find even trace amounts of carbonates in the rock samples they analyzed. Even if just a few tens of millibars of carbon dioxide had been present in the atmosphere when a lake existed in the Gale Crater, it would have produced enough carbonates for Curiosity’s CheMin to detect. This latest find adds to a paradox that has been plaguing Mars researchers for years.

Basically, researchers have noted that there is a serious discrepancy between what surface features indicate about Mars’ past, and what chemical and geological evidence has to say. Not only is there plenty of evidence that the planet had a denser atmosphere in the past, more than four decades of orbital imaging (and years worth of surface data) have yielded ample geomorphological evidence that Mars once had surface water and an active hydrological cycle.

However, scientists are still struggling to produce models that show how the Martian climate could have maintained the types of conditions necessary for this to have been the case. The only successful model so far has been one in which the atmosphere contained a significant amount of CO2 and hydrogen. Unfortunately, an explanation for how this atmosphere could be created and sustained remains elusive.

In addition, the geological and chemical evidence for such a atmosphere existing billions of years ago has also been in short supply. In the past, surveys by orbiters were unable to find evidence of carbonate minerals on the surface of Mars. It was hoped that surface missions, like Curiosity, would be able to resolve this by taking soil and drill samples where water had been known to exist.

But as Bristow explained, his team’s study has effectively closed the door on this:

“It’s been a mystery why there hasn’t been much carbonate seen from orbit. You could get out of the quandary by saying the carbonates may still be there, but we just can’t see them from orbit because they’re covered by dust, or buried, or we’re not looking in the right place. The Curiosity results bring the paradox to a focus. This is the first time we’ve checked for carbonates on the ground in a rock we know formed from sediments deposited under water.”

There are several possible explanations for this paradox. On the one hand, some scientists have argued that the Gale Crater Lake may not have been an open body of water and was perhaps covered in ice, which was just thin enough to still allow for sediments to get in. The problem with this explanation is that if this were true, there would be discernible indications left behind – which would include deep cracks in the soft sedimentary lakebed rock.

But since these indications have not been found, scientists are left with two lines of evidence that do not match up. As Ashwin Vasavada, Curiosity’s Project Scientist, put it:

“Curiosity’s traverse through streambeds, deltas, and hundreds of vertical feet of mud deposited in ancient lakes calls out for a vigorous hydrological system supplying the water and sediment to create the rocks we’re finding. Carbon dioxide, mixed with other gases like hydrogen, has been the leading candidate for the warming influence needed for such a system. This surprising result would seem to take it out of the running.”

Luckily, incongruities in science are what allow for new and better theories to be developed. And as the exploration of the Martian surface continues  – which will benefit from the arrival of the ExoMars and the Mars 2020 missions in the coming years – we can expect additional evidence to emerge. Hopefully, it will help point the way towards a resolution for this paradox, and not complicate our theories even more!

Martian Mineral Points Toward Past Habitability

For over a year, the Curiosity rover has been making its way up the slopes of Mount Sharp, the central peak within the Gale Crater. As the rover moves higher along this formation, it has been taking drill samples so that it might look into Mars’ ancient past. Combined with existing evidence that water existed within the crater, this would have provided favorable conditions for microbial life.

And according to the most recent findings announced by the Curiosity science team, the upper levels of the mountain are rich in minerals that are not found at the lower levels. These findings reveal much about how the Martian environment has changed over the past few billion years, and are further evidence that Mars may have once been habitable.

The findings were presented at the Fall meeting of the American Geophysical Union (AGU), which began on Monday, Dec. 12th, in San Fransisco. During the meeting, John Grotzinger – the Fletcher Jones Professor of Geology at Caltech and the former Project Scientist for the Curiosity mission – and other members of Curiosity’s science team shared what the rover discovered while digging into mineral veins located in the higher, younger layers of Mount Sharp.

This pair of drawings depicts the same location at Gale Crater on at two points in time: now and billions of years ago. Water moving beneath the ground, as well as water above the surface in ancient rivers and lakes, provided favorable conditions for microbial life, if Mars has ever hosted life.

To put it simply, mineral veins are a great way to study the movements of water in an area. This is due to the fact that veins are the result of cracks in layered rock being filled with chemicals that are dissolved in water – a process which alters the chemistry and composition of rock formations. What the rover found was that at higher layers hematite, clay minerals and boron are more abundant than what has been observed at lower, older layers.

These latest findings paint a complex picture of the region, where groundwater interactions led to clay-bearing sediments and diverse minerals being deposited over time. As Grotzinger explained, this kind of situation is favorable as far as habitability is concerned:

“There is so much variability in the composition at different elevations, we’ve hit a jackpot. A sedimentary basin such as this is a chemical reactor. Elements get rearranged. New minerals form and old ones dissolve. Electrons get redistributed. On Earth, these reactions support life.”

At present, no evidence has been found that microbial life actually existed on Mars in the past. However, since it first landed back in 2012, the Curiosity mission has uncovered ample evidence that conditions favorable to life existed billions of years ago. This is possible thanks to the fact that Mount Sharp consists of layered sedimentary deposits, where each one is younger than the one beneath it.

These sedimentary layers act as a sort of geological and environmental record for Mars; and by digging into them, scientists are able to get an idea of what Mars’ early history looked like. In the past, Curiosity spent many years digging around in the lower layers, where it found evidence of liquid water and all the key chemical ingredients and energy needed for life.

Since that time, Curiosity has climbed higher along Mount Sharp and examined younger layers, the purpose of which has been to reconstruct how the Martian environment changed over time. As noted, the samples Curiosity recently obtained showed greater amounts of hematite, clay minerals and boron. All of these provide very interesting clues as to what kinds of changes took place.

For instance, compared to previous samples, hematite was the most dominant iron oxide mineral detected, compared to magnetite (which is a less-oxidized form of iron oxide). The presence of hematite, which increases with distance up the slope of Mount Sharp, suggests both warmer conditions and more interaction with the atmosphere at higher levels.

The increasing concentration of this minerals – relative to magnetite at lower levels – also indicates that environmental changes have occurred where the oxidation of iron increased over time. This process, in which more electrons are lost via chemical exchanges, can provide the energy necessary for life.

In addition, Curiosity’s Chemistry and Camera (ChemCam) instrument has also noted increased (but still minute)) levels of borons within veins composed primarily of calcium sufate. On Earth, boron is associated with arid sites where water has evaporated, and its presence on Mars was certainly unexpected. No previous missions have ever detected it, and the environmental implications of it being present in such tiny amounts are unclear.

On the one hand, it is possible that evaporation within the lake bed created a boron-deposit deeper inside Mount Sharp. The movement of groundwater within could have then dissolved some of this, redepositing trace amounts at shallower levels where Curiosity was able to reach it. On the other hand, it could be that changes in the chemistry of clay-bearing deposits affected how boron was absorbed by groundwater and then redeposited.

Either way, the differences in terms of the composition of upper and lower levels in the Gale Crater creates a very interesting picture of how the local environment changed over time:

“Variations in these minerals and elements indicate a dynamic system. They interact with groundwater as well as surface water. The water influences the chemistry of the clays, but the composition of the water also changes. We are seeing chemical complexity indicating a long, interactive history with the water. The more complicated the chemistry is, the better it is for habitability. The boron, hematite and clay minerals underline the mobility of elements and electrons, and that is good for life.”

It seems that with every discovery, the long history of “Earth’s Twin” is becoming more accessible, yet more mysterious. The more we learn about it past and how it came to be the cold, desiccated place we know today, the more we want to know!

Our beyond magnificent Curiosity rover has just finished her latest Red Planet drilling campaign – at the rock target called “Quela” – into the simply unfathomable alien landscapes she is currently exploring at the “Murray Buttes” region of lower Mount Sharp. And it’s all in a Sols (or Martian Day’s) work for our intrepid Curiosity!

“These images are literally out of this world.. I don’t think I have seen anything like them on Earth!” Jim Green, Planetary Sciences Director at NASA Headquarters, Washington, D.C., explained to Universe Today.

The “Murray Buttes” region is just chock full of the most stunning panoramic vistas that NASA’s Curiosity Mars Science Laboratory rover has come upon to date. Observe and enjoy them in our exclusive new photo mosaics above and below.

“We always try to find some sort of Earth analog but these make exploring another world all worth it!” Green gushed in glee.

They fill the latest incredible chapter in her thus far four year long quest to trek many miles (km) from the Bradbury landing site across the floor of Gale Crater to reach the base region of humongous Mount Sharp.

And these adventures are just a prelude to the even more glorious vistas she’ll investigate from now on – as she climbs higher and higher on an expedition to thoroughly examine the mountains sedimentary layers and unravel billions and billions of years of Mars geologic and climatic history.

Drilling holes into Mars during the Red Planet trek and carefully analyzing the pulverized samples with the rovers pair of miniaturized chemistry laboratories (SAM and CheMin) is the route to the answer of how and why Mars changed from a warmer and wetter planet in the ancient past to the cold, dry and desolate world we see today.

The rock target named “Quela” is located at the base of one of the buttes dubbed “Murray Butte number 12,” according to the latest mission update from Prof. John Bridges, a Curiosity rover science team member from the University of Leicester, England.

It took two tries to get the drilling done due to a technical issue, but all went well in the end and it was well worth the effort at a place never before explored by an emissary from Earth.

“The drill (successful at second attempt) is at Quela.”

The full depth drilling was completed on Sol 1464, Sept. 18, 2016 using the percussion drill at the terminus of the outstretched 7-foot-long (2-meter-long) robotic arm – as confirmed by imaging and further illustrated in our navcam camera photo mosaic.

And that immediately provided valuable insight into climate change on Mars.

“You can see how red and oxidised the tailings are, suggesting changing environmental conditions as we progress through the Mt. Sharp foothills,” Bridges explained in the mission update.

Curiosity bore holes measure approximately 0.63 inch (1.6 centimeters) in diameter and 2.6 inches (6.5 centimeters) deep.

To give you the context of the Murray Buttes region and the drilling at Quela, the image processing team of Ken Kremer and Marco Di Lorenzo has begun stitching together wide angle mosaic landscape views and up close views of the drilling using raw images from the variety of cameras at Curiosity’s disposal.

The next steps after boring into Quela were to “sieve the new sample, dump the unsieved fraction, and drop some of the sieved sample into CheMin,” says Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

“But first, ChemCam will acquire passive spectra of the Quela drill tailings and use its laser to measure the chemistry of the wall of the new drill hole and of bedrock targets “Camaxilo” and “Okakarara.” Right Mastcam images of these targets are also planned.”

“After sunset, MAHLI will use its LEDs to take images of the drill hole from various angles and of the CheMin inlet to confirm that the sample was successfully delivered. Finally, the APXS will be placed over the drill tailings for an overnight integration.”

The rover had approached the butte from the south side several sols earlier to get in place, plan for the drilling, take imagery to document stratigraphy and make compositional observations with the ChemCam laser instrument.

Sol after Sol the daily imagery transmitted back to eager researchers on Earth reveal spectacularly layered Martian rock formations in such exquisite detail that they look and feel just like America’s desert Southwest landscapes.

“These are the landforms that dominate the landscape at this point in the traverse – The Murray Buttes,” says Bridges.

What are the Murray Buttes?

“These are formed by a cap of hard aeolian rock that has been partially eroded back, overlying the Murray mudstone.”

The imagery of the Murray Buttes and mesas show them to be eroded remnants of ancient sandstone that originated when winds deposited sand after lower Mount Sharp had formed.

Scanning around the Murray Buttes mosaics one sees finely layered rocks, sloping hillsides, the distant rim of Gale Crater barely visible through the dusty haze, dramatic hillside outcrops with sandstone layers exhibiting cross-bedding.

The presence of “cross-bedding” indicates that the sandstone was deposited by wind as migrating sand dunes, says the team.

Curiosity spent some six weeks or so traversing and exploring the Murray Buttes.

So after collecting all that great drilling data at Quela, the team is ready for even more spectacular new adventures!

“While the Murray Buttes were spectacular and interesting, it’s good to be back on the road again, as there is much more of Mt. Sharp to explore!” concludes Herkenhoff.

And the team is already commanding Curiosity to drive ahead in hot pursuit of the next drill target!

Three years ago, the team informally named the Murray Buttes site to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.

As of today, Sol 1470, September 24, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing inside Gale Crater, and taken over 355,000 amazing images.

Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.

KENNEDY SPACE CENTER VISITOR COMPLEX, FL- Think a Holodeck adventure on Star Trek guided by real life Apollo 11 moonwalker Buzz Aldrin and you’ll get a really good idea of what’s in store for you as you explore the surface of Mars like never before in the immersive new ‘Destination Mars’ interactive holographic exhibit opening to the public today, Monday, Sept.19, at the Kennedy Space Center visitor complex in Florida.

The new Red Planet exhibit was formally opened for business during a very special ribbon cutting ceremony featuring Buzz Aldrin as the star attraction – deftly maneuvering the huge ceremonial scissors during an in depth media preview and briefing on Sunday, Sept. 18, 2016, including Universe Today.

The fabulous new ‘Destination Mars’ limited engagement exhibit magically transports you to the surface of the Red Planet via Microsoft HoloLens technology.

It literally allows you to ‘Walk on Mars’ using real imagery taken by NASA’s Mars Curiosity rover and explore the alien terrain, just like real life scientists on a geology research expedition.

“Technology like HoloLens leads us once again toward exploration,” Aldrin said during the Sept. 18 media preview. “It’s my hope that experiences like “Destination: Mars” will continue to inspire us to explore.”

Destination Mars was jointly developed by NASA’s Jet Propulsion Laboratory – which manages the Curiosity rover mission for NASA – and Microsoft HoloLens.

Buzz was ably assisted at the grand ribbon cutting ceremony by Bob Cabana, former shuttle commander and current Kennedy Space Center Director, Therrin Protze, chief operating officer of the visitor complex, Kudo Tsunoda of Microsoft, and Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California.

The experience is housed in a pop-up theater that only runs for the next three and a half months, until New Years Day, January 1, 2017.

Before entering the theater, you will be fitted with specially adjusted HoloLens headsets individually tailored to your eyes.

The entire ‘Destination Mars’ experience only lasts barely 8 minutes.
So, if you are lucky enough to get a ticket inside you’ll need to take advantage of every precious second to scan around from left and right and back, and top to bottom. Be sure to check out Mount Sharp and the rim of Gale Crater.

You’ll even be able to find a real drill hole that Curiosity bored into the Red Planet at Yellowknife Bay about six months after the nailbiting landing in August 2012.

During your experience you will be guided by Buzz and Curiosity rover driver Erisa Hines of JPL. They will lead you to areas of Mars where the science team has made many breakthrough discoveries such as that liquid water once flowed on the floor of Curiosity’s Gale Crater landing site.

The scenes come to life based on imagery combining the Mastcam color cameras and the black and white navcam cameras, Jeff Norris of NASA’s Jet Propulsion Laboratory in Pasadena, California, told Universe Today in an interview.

Among the surface features visited is Yellowknife Bay where Curiosity conducted the first interplanetary drilling and sampling on another planet in our Solar System. The sample were subsequently fed to and analyzed by the pair of miniaturized chemistry labs – SAM and CheMin – inside the rovers belly.

They also guide viewers to “a tantalizing glimpse of a future Martian colony.”

“The technology that accomplishes this is called “mixed reality,” where virtual elements are merged with the user’s actual environment, creating a world in which real and virtual objects can interact, “ according to a NASA description.

“The public experience developed out of a JPL-designed tool called OnSight. Using the HoloLens headset, scientists across the world can explore geographic features on Mars and even plan future routes for the Curiosity rover.”

Curiosity is currently exploring the spectacular looking buttes in the Murray Buttes region in lower Mount Sharp. Read my recent update here.

The most stunning panoramic vistas likely ever snapped by NASA’s Curiosity rover reveal spectacularly layered Martian rock formations in such exquisite detail that they look and feel just like America’s desert Southwest landscapes. They were just captured a week ago and look like a scene straight out of the hugely popular science fiction movie ‘The Martian’ – only they are real !!

Indeed several magnificent panoramas were taken by Curiosity in just the past week and you can see our newly stitched mosaic versions of several – above and below.

The rock formations lie in the “Murray Buttes” region of lower Mount Sharp where Curiosity has been exploring for roughly the past month. She just finished a campaign of detailed science observations and is set to bore a new sampling hole into the Red Planet, as you read this.

While scouting around the “Murray Buttes,” the SUV sized rover captured thousands of color and black and white raw images to document the geology of this thus far most unrivaled spot on the Red Planet ever visited by an emissary from Earth.

So the image processing team of Ken Kremer and Marco Di Lorenzo has begun stitching together wide angle mosaic views starting with images gathered by the high resolution mast mounted Mastcam right color camera, or M-100, on Sept, 8, 2016, or Sol 1454 of the robots operations on Mars.

The mosaics give context and show us exactly what the incredible alien surroundings look like where the six wheeled rover is exploring today.

The imagery of the Murray Buttes and mesas show them to be eroded remnants of ancient sandstone that originated when winds deposited sand after lower Mount Sharp had formed.

Scanning around the Murray Buttes mosaics one sees finely layered rocks, sloping hillsides, the distant rim of Gale Crater barely visible through the dusty haze, dramatic hillside outcrops with sandstone layers exhibiting cross-bedding. The presence of “cross-bedding” indicates that the sandstone was deposited by wind as migrating sand dunes, says the team.

But there is no time to rest as she was commanded to head further south to the last of these Murray Buttes. And right now the team is implementing a plan for Curiosity to drill a new hole in Mars today – at a target named “Quela” at the base of the last of the buttes. The rover approached the butte from the south side a few days ago to get in place and plan for the drilling, take imagery to document stratigraphy and make compositional observations with the ChemCam laser instrument.

“It’s always an exciting day on Mars when you prepare to drill another sample – an engineering feat that we’ve become so accustomed to that I sometimes forget how impressive this really is!” wrote Lauren Edgar, in a mission update today. Edgar is a Research Geologist at the USGS Astrogeology Science Center and a member of the MSL science team.

Curiosity will then continue further south to begin exploring higher and higher sedimentary layers up Mount Sharp. The “Murray Buttes” are the entry way along Curiosity’s planned route up lower Mount Sharp.

Meanwhile Curiosity is still conducting science observations of the last drill sample gathered from the “Marimba” target in August focusing on MAHLI and APXS examination of the dump pile leftovers from the sieved sample. She just completed chemical analysis of the sieved sample using the miniaturized SAM and CheMin internal chemistry laboratories.

It’s interesting to note that although the buttes are striking, their height also presents communications issues by blocking radio signals with NASA’s orbiting relay satellites. NASA’s Opportunity rover faced the same issues earlier this year while exploring inside the high walled Marathon Valley along Ecdeavour Crater.

“While the buttes are beautiful, they pose a challenge to communications, because they are partially occluding communications between the rover and the satellites we use to relay data (MRO and ODY), so sometimes the data volume that we can relay is pretty low” wrote Edgar.

“But it’s a small price to pay for the great stratigraphic exposures and gorgeous view!”

Four years after a nail biting touchdown on the Red Planet, NASA’s SUV-sized Curiosity rover is at last nearing the long strived for “Murray Buttes” formation on the lower reaches of Mount Sharp.

This is a key milestone for the Curiosity mission because the “Murray Buttes” are the entry way along Curiosity’s planned route up lower Mount Sharp.

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.

The area features eroded mesas and buttes that are reminiscent of the U.S. Southwest.

So the team directed the rover to capture a 360-degree color panorama using the robots mast mounted Mastcam camera earlier this month on Aug. 5.

The full panorama shown above combines more than 130 images taken by Curiosity on Aug. 5, 2016, during the afternoon of Sol 1421 by the Mastcam’s left-eye camera.

In particular note the dark, flat-topped mesa seen to the left of the rover’s arm. It stands about 50 feet (about 15 meters) high and, near the top, about 200 feet (about 60 meters) wide.

Coincidentally, Aug. 5 also marks the fourth anniversary of the six wheeled rovers landing on the Red Planet via the unprecedented Sky Crane maneuver.

You can explore this spectacular Mars panorama in great detail via this specially produced 360-degree panorama from JPL. Simply move the magnificent view back and forth and up and down and all around with your mouse or mobile device.

Video Caption: This 360-degree panorama was acquired on Aug. 5, 2016, by the Mastcam on NASA’s Curiosity Mars rover as the rover neared features called “Murray Buttes” on lower Mount Sharp. The dark, flat-topped mesa seen to the left of the rover’s arm is about 50 feet (about 15 meters) high and, near the top, about 200 feet (about 60 meters) wide.

“The buttes and mesas are capped with rock that is relatively resistant to wind erosion. This helps preserve these monumental remnants of a layer that formerly more fully covered the underlying layer that the rover is now driving on,” say rover scientists.

“The relatively flat foreground is part of a geological layer called the Murray formation, which formed from lakebed mud deposits. The buttes and mesas rising above this surface are eroded remnants of ancient sandstone that originated when winds deposited sand after lower Mount Sharp had formed. Curiosity closely examined that layer — the Stimson formation — during the first half of 2016 while crossing a feature called “Naukluft Plateau” between two exposures of the Murray formation.”

Three years ago, the team informally named the site to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.

As of today, Sol 1447, August 31, 2016, Curiosity has driven over 7.9 miles (12.7 kilometers) since its August 2012 landing, and taken over 348,500 amazing images.

Curiosity Finds Ancient Mars Likely Had More Oxygen and Was More Hospitable to Life

New chemical science findings from NASA’s Mars rover Curiosity indicate that ancient Mars likely had a higher abundance of molecular oxygen in its atmosphere compared to the present day and was thus more hospitable to life forms, if they ever existed.

Thus the Red Planet was much more Earth-like and potentially habitable billions of years ago compared to the cold, barren place we see today.

Curiosity discovered high levels of manganese oxide minerals in rocks investigated at a location called “Windjana” during the spring of 2014.

Manganese-oxide minerals require abundant water and strongly oxidizing conditions to form.

“Researchers found high levels of manganese oxides by using a laser-firing instrument on the rover. This hint of more oxygen in Mars’ early atmosphere adds to other Curiosity findings — such as evidence about ancient lakes — revealing how Earth-like our neighboring planet once was,” NASA reported.

The newly announced results stem from results obtained from the rovers mast mounted ChemCam or Chemistry and Camera laser firing instrument. ChemCam operates by firing laser pulses and then observes the spectrum of resulting flashes of plasma to assess targets’ chemical makeup.

“The only ways on Earth that we know how to make these manganese materials involve atmospheric oxygen or microbes,” said Nina Lanza, a planetary scientist at Los Alamos National Laboratory in New Mexico, in a statement.

“Now we’re seeing manganese oxides on Mars, and we’re wondering how the heck these could have formed?”

The discovery is being published in a new paper in the American Geophysical Union’s Geophysical Research Letters. Lanza is the lead author.

The manganese oxides were found by ChemCam in mineral veins investigated at “Windjana” and are part of geologic timeline being assembled from Curiosity’s research expedition across of the floor of the Gale Crater landing site.

Scientists have been able to link the new finding of a higher oxygen level to a time when groundwater was present inside Gale Crater.

“These high manganese materials can’t form without lots of liquid water and strongly oxidizing conditions,” says Lanza.

“Here on Earth, we had lots of water but no widespread deposits of manganese oxides until after the oxygen levels in our atmosphere rose.”

The high-manganese materials were found in mineral-filled cracks in sandstones in the “Kimberley” region of the crater.

High concentrations of manganese oxide minerals in Earth’s ancient past correspond to a major shift in our atmosphere’s composition from low to high oxygen atmospheric concentrations. Thus its reasonable to suggest the same thing happened on ancient Mars.

As part of the investigation, Curiosity also conducted a drill campaign at Windjana, her 3rd of the mission.

How much manganese oxide was detected and what is the meaning?

“The Curiosity rover observed high-Mn abundances (>25 wt% MnO) in fracture-filling materials that crosscut sandstones in the Kimberley region of Gale crater, Mars,” according to the AGU paper.

“On Earth, environments that concentrate Mn and deposit Mn minerals require water and highly oxidizing conditions, hence these findings suggest that similar processes occurred on Mars.”

“Based on the strong association between Mn-oxide deposition and evolving atmospheric dioxygen levels on Earth, the presence of these Mn-phases on Mars suggests that there was more abundant molecular oxygen within the atmosphere and some groundwaters of ancient Mars than in the present day.”

NASA’s Curiosity Mars Science Laboratory (MSL) rover successfully bored a brand new hole in Mars at a tantalizing sandstone outcrop in the ‘Lubango’ fracture zone this past weekend on Sol 1320, Apr. 23, and is now carefully analyzing the shaken and sieved drill tailings for clues to Mars watery past atop the Naukluft Plateau.

“We have a new drill hole on Mars!” reported Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

“All of the activities planned for last weekend have completed successfully.”

“Lubango” counts as the 10th drilling campaign since the one ton rover safely touched down on the Red Planet some 44 months ago inside the targeted Gale Crater landing site, following the nailbiting and never before used ‘sky crane’ maneuver.

After transferring the cored sample to the CHIMRA instrument for sieving it, a portion of the less than 0.15 mm filtered material was successfully delivered this week to the CheMin miniaturized chemistry lab situated in the rovers belly.

CheMin is now analyzing the sample and will return mineralogical data back to scientists on earth for interpretation.

The science team selected Lubango as the robots 10th drill target after determining that it was altered sandstone bedrock and had an unusually high silica content based on analyses carried out using the mast mounted ChemCam laser instrument.

Indeed the rover had already driven away for further scouting and the team then decided to return to Lubango after examining the ChemCam results. They determined the ChemCam and other data observation were encouraging enough – regarding how best to sample both altered and unaltered Stimson bedrock – to change course and drive backwards.

Lubango sits along a fracture in an area that the team dubs the Stimson formation, which is located on the lower slopes of humongous Mount Sharp inside Gale Crater.

Since early March, the rover has been traversing along a rugged region dubbed the Naukluft Plateau.

“The team decided to drill near this fracture to better understand both the altered and unaltered Stimson bedrock,” noted Herkenhoff.

See our photo mosaic above showing the geologically exciting terrain surrounding Curiosity with its outstretched 7-foot-long (2-meter-long) robotic arm after completing the Lubango drill campaign on Sol 1320. The mosaic was created by the imaging team of Ken Kremer and Marco Di Lorenzo.

Its again abundantly clear from the images that beneath the rusty veneer of the Red Planet lies a greyish interior preserving the secrets of Mars ancient climate history.

The team then commanded Curiosity to dump the unsieved portion of the sample onto the ground and examine the leftover drill tailing residues with the Mastcam, Navcam, MAHLI multispectral characterization cameras and the APXS spectrometer. ChemCam is also being used to fire laser shots in the wall of the drill hole to make additional chemical measurements.

To complement the data from Lubango, scientists are now looking around the area for a suitable target of unaltered Stimson bedrock as the 11th drill target.

“The color information provided by Mastcam is really helpful in distinguishing altered versus unaltered bedrock,” explained MSL science team member Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center, in a mission update.

The ChemCam laser has already shot at the spot dubbed “Oshikati,” a potential target for the next drilling campaign.

“On Sunday we will drive to our next drilling location, which is on a nearby patch of normal-looking Stimson sandstone,” wrote Ryan Anderson, planetary scientist at the USGS Astrogeology Science Center and a member of the ChemCam team on MSL in today’s (Apr. 28) mission update.

As time permits, the Navcam imager is also being used to search for dust devils.

As I reported here, Opportunity recently detected a beautiful looking dust devil on the floor of Endeavour crater on April 1. Dust devil detections by the NASA rovers are relatively rare.

Curiosity has been driving to the edge of the Naukluft Plateau to reach the interesting fracture zone seen in orbital data gathered from NASA’s Mars orbiter spacecraft.

The rover is almost finished crossing the Naukluft Plateau which is “the most rugged and difficult-to-navigate terrain encountered during the mission’s 44 months on Mars,” says NASA.

Prior to climbing onto the Naukluft Plateau the rover spent several weeks investigating sand dunes including the two story tall Namib dune.
