As NASA’s Opportunity rover approaches the 12th anniversary of landing on Mars, her greatest science discoveries yet are likely within grasp in the coming months since she has successfully entered Marathon Valley from atop a Martian mountain and is now prospecting downhill for outcrops of water altered clay minerals.

The valley is the gateway to alien terrain holding significant caches of the water altered minerals that formed under environmental conditions conducive to support Martian microbial life forms, if they ever existed. But as anyone who’s ever climbed down a steep hill knows, you have to be extra careful not to slip and slide and break something, no matter how beautiful the view is – Because no one can hear you scream on Mars! See the downward looking valley view above.

After a years long Martian mountain climbing and mountain top exploratory trek, Opportunity entered a notch named Marathon Valley from atop a breathtakingly scenic ridge overlook atop the western rim of Endeavour Crater.

Marathon Valley measures about 300 yards or meters long and cuts downhill through the west rim of Endeavour crater from west to east. Endeavour crater spans some 22 kilometers (14 miles) in diameter.

See our photo mosaics illustrating Opportunity’s view around and about Marathon Valley and Endeavour Crater, created by the image processing team of Ken Kremer and Marco Di Lorenzo.

Our mosaic above affords a downward looking view from Marathon Valley on Sol 4144, Sept. 20. It uniquely combines raw images from the hazcam and navcam cameras to gain a wider perspective panoramic view of the steep walled valley, and also shows the rover at work stretching out the robotic arm to potential clay mineral rock targets at left. Opportunity’s shadow and wheel tracks are visible at right.

In late July, Opportunity began the decent into the valley from the western edge and started investigating scientifically interesting rock targets by conducting a month’s long “walkabout” survey ahead of the upcoming frigid Martian winter – the seventh since touchdown at Meridiani Planum in January 2004.

The walkabout was done to identify targets of interest for follow up scrutiny in and near the valley floor. Opportunity’s big sister Curiosity conducted a similarly themed “walkabout” at the base of Mount Sharp near her landing site located on the opposite side of the Red Planet.

“The valley is somewhat like a chute directed into the crater floor, which is a long ways below. So it is somewhat scary, but also pretty interesting scenery,” writes Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in a mission update.

“Its named Marathon Valley because the rover traveled one marathon’s distance to reach it,” Prof. Ray Arvidson, the rover Deputy Principal Investigator of Washington University told Universe Today.

The NASA rover exceeded the distance of a marathon on the surface of Mars on March 24, 2015, Sol 3968. Opportunity has now driven over 26.46 miles (42.59 kilometers) over nearly a dozen Earth years.

Now for the first time in history, a human emissary has arrived to conduct an up close inspection of and elucidate clues into this regions potential regarding Martian habitability.

The ancient, weathered slopes around Marathon Valley hold a motherlode of ‘phyllosilicate’ clay minerals, based on data obtained from the extensive Mars orbital measurements gathered by the CRISM spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.

Initially the science team was focused on investigating the northern region of the valley while the sun was still higher in the sky and generating more power for research activities from the life giving solar arrays.

“We have detective work to do in Marathon Valley for many months ahead,” said Opportunity Deputy Principal Investigator Ray Arvidson, of Washington University in St. Louis.

But now that the rover is descending into a narrow valley with high walls, the rovers engineering handlers back on Earth have to exercise added caution regarding exactly where they send the Opportunity on her science forays during each sols drive, in order to maintain daily communications.

The high walls to the north and west of the valley ridgeline has already caused several communications blackouts for the “low-elevation Ultra-High-Frequency (UHF) relay passes to the west,” according to the JPL team controlling the rover.

Indeed on two occasions in mid September – coinciding with the days just before and after our Sol 4144 (Sept. 20) photo mosaic view above, “no data were received as the orbiter’s flight path was below the elevation on the valley ridgeline.

On Sept 17 and Sept. 21 “the high ridgeline of the valley obscured the low-elevation pass” and little to no data were received. However the rover did gather imagery and spectroscopic measurements for later transmission.

Now that winter is approaching the rover is moving to the southern side of Marathon Valley to soak up more of the sun’s rays from the sun-facing slope and continue research activities.

“During the Martian late fall and winter seasons Opportunity will conduct its measurements and traverses on the southern side of the valley,” says Arvidson.

“When spring arrives the rover will return to the valley floor for detailed measurements of outcrops that may host the clay minerals.”

The shortest-daylight period of this seventh Martian winter for Opportunity will come in January 2016.

Why Don’t We See the Curiosity Rover’s Arm When it Takes a Selfie?

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Big Sky" site. Credit: NASA/JPL-Caltech/MSSS

Every time the Curiosity rover takes a ‘selfie’ on Mars, we get the same questions: “How was this picture taken?” “Why isn’t the rover’s arm or the camera visible in this picture?” “In all of Curiosity’s selfies, the camera mast is never visible… why?” And (sigh) “What is NASA hiding???”

The answer is simple and quite logical. Look any selfie image you’ve taken. Does your hand show up in the picture?

No, because it is behind the camera.

The same is true with the rover’s arm. For the most part, it is behind the camera, so it isn’t part of the picture. In your own selfies, if you’ve done a good job of positioning things, your arm doesn’t appear in the photo either. For example, take a look at this selfie taken last night by Astronomy Cast co-host Pamela Gay of her co-host (and Universe Today publisher) Fraser Cain, along with their fellow speakers at the Next Frontiers Symposium at Ohio State University.

You’ll notice Pamela’s arm isn’t showing, even though she took the picture of herself, just like the rover takes pictures of itself.

Just think of the rover’s arm as the ultimate interplanetary selfie stick. The best selfie-stick pictures are where the stick doesn’t show up in the image and it appears you had your own photographer. That’s what happens with the Curiosity rover self-portraits.

It’s important to note that while the rover selfies look like they are just one single image taken by the wide-angle camera on the rover, it is actually a series of individual images stitched together. The picture above is made from dozens of images the rover took of itself with the Mars Hand Lens Imager (MAHLI) camera at the end of the rover’s robotic arm. Curiosity moves its robotic arm around and over itself and the ground, taking pictures from every angle. These pictures are then stitched, just like panoramic images are put together to form a complete image of your total view. The rover’s arm isn’t long enough to make the camera’s field of view big enough to get the entire rover in one shot (similar to how it works if you hold your camera/phone close to your face you only get one feature, like your nose or eyes, not your entire body.)

Update: As for the questions of why the rover’s arm doesn’t show up in these rover selfie images, I conferred with Guy Webster from JPL and he said that portions of the arm do show up in some of the images used to create the selfie shots, but the portion of the arm pictured is very limited, and the team feels it would be even more confusing to include the small parts of the arm that are in some of the images and so have decided to leave it out entirely.

“Some of the component images do indeed show glimpses of the arm,” Webster said via email. “There’s selectivity in choosing which parts of which component frames to use in assembling the mosaic, to avoid having discontinuous bits of arm in the scene. That would cause confusion even quicker than making choices that leave out the arm.”

For example, here is one image from the series of pictures taken by the MAHLI to create the selfie, and it shows just a small piece of the arm, near the “shoulder”:

You can see the entire collection of MAHLI images from Sol 1126 (Oct. 6, 2015) here. You can see how few images show parts of the arm, and how little of the arm shows up in the ones that do.

For the most part, though, because of the flexibility of the robotic arm and the way it is able to move, the arm ends up behind the camera. As Curiosity’s Engineering Camera Team Leader Justin Maki explains in the video below, “The rover is imaging the deck while the arm is behind the camera, and then to image the ground … again the arm is behind the camera when taking these pictures. When we stitch them all together, you don’t see the arm in any of the pictures.”

Click on the image to start the video (which shows very well why the arm isn’t in most of the shots):

It’s interesting to note, that while the lead image above — the latest rover selfie — does not include the rover’s robotic arm, the shadow of the arm is visible on the ground. You’ll notice there seems to be an extra “joint” in the arm, which is just part of the image editing, particularly the stacking of the images where the ground is, where the image editors used more than one image for that area. For the selfie image below, taken in 2012, the imaging team chose not to include any shadow of the arm.

Why does the rover imaging team take these rover selfies? Are they just joining in on the selfie craze here on Earth?

These images are actually a great way for the rover team to look at all the components on Curiosity and make sure everything looks like it’s in good shape. The wheels are of particular interest because there has been some damage to them from driving over sharp rocks. These images also document various areas where the rover has worked, and often include things like the holes the rover has drilled into the Martian rocks and soil.

Emily Lakdawalla at The Planetary Society has written an extremely detailed post on how the rover takes self-portraits. She created this composite image of the 72 individual frames the Mars Hand Lens Imager (MAHLI) had to take in order to cover the 360-degree view showing the rover’s underside, a “belly selfie“:

Curiosity's arm-mounted MAHLI camera took 72 individual photos over a period of about an hour in order to cover the entire rover and a lower hemisphere including 360 degrees around the rover and more than 90 degrees of elevation. It took 2 tiers of 20 images to cover the entire horizon, and fewer images at lower elevations to cover the bottom of the image sphere. The arm was kept out of most of the images but it was impossible to keep the arm's shadow from falling on the ground in positions immediately in front of the rover.

NASA’s Curiosity rover has managed to snap another gorgeous selfie while she was hard at work diligently completing her newest Martian sample drilling campaign – at the ‘Big Sky’ site at the base of Mount Sharp, the humongous mountain dominating the center of the mission’s Gale Crater landing site – which the science team just confirmed was home to a life bolstering ancient lake based on earlier sample analyses.

And the team is already actively planning for the car sized robots next drill campaign in the next few sols, or Martian days!

Overall ‘Big Sky’ marks Curiosity’s fifth ‘taste’ of Mount Sharp – since arriving at the mountain base one year ago – and eighth drilling operation since the nail biting Martian touchdown in August 2012.

NASA’s newly published self-portrait was stitched from dozens of images taken at Big Sky last week on Oct. 6, 2015, or Sol 1126, by the high resolution Mars Hand Lens Imager (MAHLI) color camera at the end of the rover’s 7 foot long robotic arm. The view is centered toward the west-northwest.

At Big Sky, the Curiosity Mars Science Laboratory (MSL) bored into an area of cross-bedded sandstone rock in the Stimson geological unit on Sept. 29, or Sol 1119. Stimson is located on the lower slopes of Mount Sharp inside Gale Crater.

“Success! Our drill at “Big Sky” went perfectly!” wrote Ryan Anderson, a planetary scientist at the USGS Astrogeology Science Center and a member of the Curiosity ChemCam team.

The drill hole is seen at the lower left corner of the MAHLI camera selfie and appears grey along with grey colored tailing – in sharp contrast to the rust red surface. The hole itself is 0.63 inch (1.6 centimeters) in diameter.

Another panoramic view of the ‘Big Sky’ location shot from the rover’s eye perspective with the mast mounted Navcam camera, is shown in our photo mosaic view herein and created by the image processing team of Ken Kremer and Marco Di Lorenzo. The navcam mosaic was stitched from raw images taken up to Sol 1119 and colorized.

“With Big Sky, we found the ordinary sandstone rock we were looking for,” said Curiosity Project Scientist Ashwin Vasavada, in a statement.

The Big Sky drilling operation is part of a coordinated multi-step campaign to examine different types of sandstone rocks to provide geologic context.

“It also happens to be relatively near sandstone that looks as though it has been altered by fluids — likely groundwater with other dissolved chemicals. We are hoping to drill that rock next, compare the results, and understand what changes have taken place.”

Per normal operating procedures, the Big Sky sample was collected for analysis of the Martian rock’s ingredients in the rover’s two onboard laboratories – the Chemistry and Mineralogy X-Ray diffractometer (CheMin) and the Sample Analysis at Mars (SAM) instrument suite.

“We are all eagerly looking forward to the CheMin results from Big Sky to compare with our previous results from “Buckskin”! noted Anderson.

This past weekend, Curiosity successfully fed pulverized and sieved samples of Big Sky to the inlet ports for both CheMin and SAM on the rover deck.

“The SAM analysis of the Big Sky drill sample went well and there is no need for another analysis, so the rest of the sample will be dumped out of CHIMRA on Sol 1132,” said Ken Herkenhoff, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

Concurrently the team is hard at work readying the rover for the next drill campaign within days, likely at a target dubbed “Greenhorn.”

So the six wheeled rover drove about seven meters to get within range of Greenhorn.

With the sample deliveries accomplished, attention shifted to the next drilling campaign.

Today, Wednesday, Oct. 14, or Sol 1133, Curiosity was commanded “to dump the “Big Sky” sample and “thwack” CHIMRA (the Collection and Handling for in-Situ Martian Rock Analysis) to clean out any remnants of the sample,” wrote Lauren Edgar, a Research Geologist at the USGS Astrogeology Science Center and a member of MSL science team, in a mission update.

The ChemCam and Mastcam instruments are simultaneously making observations of the “Greenhorn” and “Gallatin Pass” targets “to assess chemical variations across a fracture.”

Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

As of today, Sol 1133, October 14, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 274,600 amazing images.

Go now and experience Hollywood’s blockbuster new space epic ‘The Martian’ helmed by world renowned director Ridley Scott and starring Matt Damon as the protagonist, NASA astronaut Mark Watney. And you can follow Watney’s dramatic fictional path across the Red Planet in newly released real photos and a flyover video of the region, from DLR and NASA, as it looks today.

‘The Martian’ is a mesmerizingly enjoyable cinematic triumph for everyone that’s all about science, space exploration and one man’s struggle to survive while left totally isolated on the Red Planet in the face of seemingly insurmountable odds – relying on his wits alone to endure “on a planet where nothing grows” while hoping somehow for a rescue by NASA four years in the future.

The movie combines compelling and plausible storytelling with outstanding special effects that’s clearly delighting huge audiences worldwide with a positive and uplifting view of what could be achieved in the future – if only we really put our minds to it!

Based on the bestselling book by Andy Weir, ‘The Martian’ movie from 20th Century Fox tells the spellbinding story of how NASA astronaut Mark Watney is accidentally stranded on the surface of Mars during the future Ares 3 manned expedition in 2035, after a sudden and unexpectedly fierce dust storm forces the rest of the six person crew – commanded by Jessica Chastain as Commander Lewis – to quickly evacuate after they believe he is dead.

Now you can follow the fictional exploits of Mark Watney’s stunningly beautiful trail across the real Mars through a set of newly released maps, imagery and a 3D video created by the DLR, the German Aerospace Agency, and NASA – and based on photos taken by the European Space Agency’s Mars Express orbiter and NASA’s Mars Reconnaissance Orbiter (MRO).

DLR’s stunning 3D overflight video sequence was created from a dataset of 7300 stereo images covering roughly two-and-a-half million square kilometres of precisely mapped Martian landscape captured over the past 12 years by Mars Express High Resolution Stereo Camera (HRSC). The electric score is by Stephan Elgner.

Video Caption: Following the path of The Martian – video generated using images acquired by the Mars Express orbiter. Scientists from German Aerospace Center, DLR– who specialise in producing highly accurate topographical maps of Mars – reconstructed Watney’s route using stereo image data acquired by the High Resolution Stereo Camera on board European Space Agency’s #MarsExpress spacecraft. They then compiled this data into a video that shows the spectacular landscape that the protagonist would see ‘in the future’ on his trek from Ares 3 at Acidalia Planitia/Chryse Planitia to Ares 4 at Schiaparelli Crater.

Ridley Scotts ‘The Martian’ takes place mostly on the surface of the Red Planet and is chock full of breathtakingly beautiful panoramic vistas. In the book you can only imagine Mars. In the movie Scott’s talents shine as he immerses you in all the action on the alien world of Mars from the opening scene.

Starting with the landing site for Watney’s Ares 3 mission crew at Acidalia Planitia, the book and movie follows his triumphs and tribulations, failures and successes as he logically solves one challenging problem after another – only to face increasingly daunting and unexpected hurdles as time goes by and supplies run low.

The DLR route map shows a real topographic view of Watney’s initial journey back and forth from the fictional Ares 3 landing site to the actual landing site of NASA’s 1997 Mars Pathfinder lander and Sojourner rover mission at the mouth of Ares Vallis.

The map continues with Watney’s months-long epic trek to the fictional landing site of Ares 4 Mars Ascent Vehicle (MAV) spacecraft at Schiaparelli Crater, by way of Marth Valles and other Martian landmarks, craters and valleys.

At the request of Andy Weir, the HiRISE camera on NASA’s MRO orbiter took photos of the Martian plain at the Ares 3 landing site in Acidalia Planitia, which is within driving distance from the Pathfinder lander and Sojourner rover in the book and movie.

The Martian is all about how Watney uses his botany, chemistry and engineering skills to “Science the sh** out of it” to grow food and survive until the hoped for NASA rescue.

Learning how to live off the land will be a key hurdle towards enabling NASA’s real strategy for long term space voyages on a ‘Journey to Mars’ and back.

‘The Martian’ is a must see movie that broadly appeals to space enthusiasts and general audiences alike who can easily identify with Watney’s ingenuity and will to live.

Since its worldwide premiere on Oct. 2, ‘The Martian’ has skyrocketed to the top of the US box office for the second weekend in a row, hauling in some $37.3 million. The total domestic box office receipts now top $108 million and rockets to over $228 million worldwide in the first 10 days alone.

I absolutely loved ‘The Martian’ when I first saw the movie on opening weekend. And enjoyed it even more the second time, when I could pick up a few details I missed the first time around.

The movie begins as the crew evacuates after they believe Watney was killed by the dust storm. Watney actually survived the storm but lost contact with NASA. The film recounts his ingenious years long struggle to survive, figure out how to tell NASA he is alive and send a rescue crew before he starves to death on a planet where nothing grows. Watney’s predicament is a survival lesson to all including NASA.

‘The Martian’ was written by Andy Weir in 2010 and the film could well break the October movie box office record currently held by ‘Gravity.’

The movie closely follows the book, which I highly recommend you read at some point.

By necessity, the 2 hour 20 minute movie cannot capture every event in the book. So there is an abbreviated sense of Watney’s detailed science to survive and lengthy overland trips.

All the heroics and difficulties in traveling to Pathfinder and back and getting communications started, as well as the final month’s long journey to Schiaparelli crater are significantly condensed, but captured in spirit.

The Martian is brilliant and intelligent and rivals Stanley Kubrik’s space epic ‘2001: A Space Odyssey’ as one of the top movies about humanities space exploration quest.

The one big science inaccuracy takes place right at the start with the violent Martian dust storm.

On Mars the atmosphere is so thin that the winds would not be anywhere near as powerful or destructive as portrayed. This is acknowledged by Weir and done for dramatic license. We can look past that since the remainder of the tale portrays a rather realistic architectural path to Mars and vision of how scientists and engineers think. Plus the dust storms can in fact kick up tremendous amounts of particles that significantly block sunlight from impinging on solar energy generating panels.

Personally I can’t wait for the ‘Directors Cut’ with an added 30 to 60 minutes of scenes that were clearly filmed – but not included in the original theatrical release.

THE MARTIAN features a star studded cast that includes Matt Damon, Jessica Chastain, Kristen Wiig, Kate Mara, Michael Pena, Jeff Daniels, Chiwetel Ejiofor, and Donald Glover.

“NASA has endorsed “The Martian’” Jim Green, NASA’s Director of Planetary Sciences, told Universe Today. Green served as technical consultant on the film.

The DLR film was created by a team led by Ralf Jaumann from the DLR Institute of Planetary Research, Principal Investigator for HRSC. He believes that producing the overflight video was not just a gimmick for a science fiction film:

“Mars generates immense fascination, and our curiosity continues to grow! Many people are interested in our research, and young people in particular want to know what it is really like up there, and how realistic the idea that one day people will leave their footprints on the surface of Mars truly is. The data acquired by HRSC shows Mars with a clarity and detail unmatched by any other experiment. Only images acquired directly on the surface, for instance by rovers like Curiosity, are even closer to reality, but they can only show a small part of the planet. Thanks to this animation, we have even noticed a few new details that we had not seen in a larger spatial context. That is why we made the film – it helps everyone see what it would be like for Watney to travel through these areas… the clouds were the only creative touches we added, because, fortunately, they do not appear in the HRSC data,” according to a DLR statement.

Here’s the second official trailer for The Martian:

As a scientist and just plain Earthling, my most fervent hope is that ‘The Martian’ will inspire our young people to get interested in all fields of science, math and engineering and get motivated to become the next generation of explorers – here on Earth and beyond to the High Frontier to benefit all Mankind.

Hot on the heels of NASA’s groundbreaking announcement on Sept. 28 of the discovery that “liquid water flows intermittently” across multiple spots on the surface of today’s Mars, scientists leading NASA’s Curiosity rover mission have confirmed that an ancient lake once filled the Gale Crater site which the robot has been methodically exploring since safely landing back in August 2012 near the base of a layered mountain known as Mount Sharp.

The new research finding from the Curiosity team was just published in the journal Science on Friday, Oct. 9, and boosts the chances that alien life may have taken hold in the form of past or present day Martian microbes.

The article is titled “Wet Paleoclimate of Mars Revealed by Ancient Lakes at Gale Crater,” with John Grotzinger, the former project scientist for the Mars Science Laboratory (MSL) mission at the California Institute of Technology in Pasadena, as lead author of the new report.

The new study is coauthored by four dozen team members intimately involved in Curiosity’s ongoing exploits and “confirmed that Mars was once, billions of years ago, capable of storing water in lakes over an extended period of time.”

“Observations from the rover suggest that a series of long-lived streams and lakes existed at some point between about 3.8 to 3.3 billion years ago, delivering sediment that slowly built up the lower layers of Mount Sharp,” said Ashwin Vasavada, current MSL project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, and co-author of the new report, in a statement.

Over the past three years, the Curiosity Mars Science Laboratory rover has been traversing the floor of Gale Crater investigating scores of different rocks and outcrops with her suite of state-of-the-art instruments, and painstakingly analyzing drill samples cored from their interiors with a pair of chemistry labs to elucidate the history of Mars based on NASA’s “follow the water” mantra.

The soundness of NASA Mars exploration strategy has repeatedly borne fruit and is now validated by overwhelming measurements gathered during Curiosity’s epic Martian trek confirming the existence of a lake where Mount Sharp now stands.

Exploring the sedimentary 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.

Since the nail biting touchdown on Aug. 5, 2012, Curiosity has been on a path towards the sedimentary layers at the lower reaches of Mount Sharp at the center of Gale Crater.

The car sized robot arrived at the foothills of Mount Sharp a year ago in September 2014, marking the start of the mountains formal investigation.

But the origin of Mount Sharp has been up for debate.

With the new data, researchers believe that the ancient lake helped fill Gale Crater with sediments deposited in layers over time that formed the foundation for Mount Sharp which now dominates the center of the crater.

“What we thought we knew about water on Mars is constantly being put to the test,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program at NASA Headquarters in Washington.

“It’s clear that the Mars of billions of years ago more closely resembled Earth than it does today. Our challenge is to figure out how this more clement Mars was even possible, and what happened to that wetter Mars.”

Mars was far wetter and warmer and possessed a much more massive atmosphere billions of years ago than it does today.

Gale Crater lake existed long before Mount Sharp ever formed during that period billions of years ago when the Red Planet was far warmer and wetter.

“Paradoxically, where there is a mountain today there was once a basin, and it was sometimes filled with water,” said Grotzinger, in a statement.

“We see evidence of about 250 feet (75 meters) of sedimentary fill, and based on mapping data from NASA’s Mars Reconnaissance Orbiter and images from Curiosity’s camera, it appears that the water-transported sedimentary deposition could have extended at least 500 to 650 feet (150 to 200) meters above the crater floor.”

Indeed there is additional evidence that the sedimentary deposits from interaction with water may be as thick as one-half mile (800 meters) above the crater floor. However beyond that there is no evidence of hydrated strata further up Mount Sharp.

But for reasons we are still trying to decipher and comprehend, Mars underwent radical climactic change between 3 and 4 billion years ago and was transformed from an ancient wet world, potentially hospitable to life, to a cold, dry desiccated world, rather inhospitable to life, that exists today.

Unlocking the mysteries, mechanisms and time periods of Mars climate change, loss of a thick atmosphere, ability to sustain liquid surface water and searching for organic compounds and for evidence of past or present habitable zones favorable to life are the questions driving NASA’s Mars Exploration program

Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

“We have tended to think of Mars as being simple,” Grotzinger mused. “We once thought of the Earth as being simple too. But the more you look into it, questions come up because you’re beginning to fathom the real complexity of what we see on Mars. This is a good time to go back to reevaluate all our assumptions. Something is missing somewhere.”

As of today, Sol 1129, October 10, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 274,000 amazing images.

Curiosity is at the vanguard of Earth’s fleet of seven robotic missions paving the path for NASA’s plans to send humans on a ‘Journey to Mars’ in the 2030s.

NASA Discovers Salty Liquid Water Flows Intermittently on Mars Today, Bolstering Chance for Life

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. However, a new study by planetary scientists indicates that these may actually be the result of dry flows. Credits: NASA/JPL/University of Arizona

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene.

The image is produced by draping an orthorectified Infrared-Red-Blue/Green(IRB)) false color image on a Digital Terrain Model (DTM). This model was produced by researchers at the University of Arizona, much like the High Resolution Imaging Science Experiment (University of Arizona). The vertical exaggeration is 1.5.

NASA and Mars planetary scientists announced today (Sept. 28) that salty “liquid water flows intermittently” across multiple spots on the surface of today’s Mars – trumpeting a major scientific discovery with far reaching implications regarding the search for life beyond Earth and bolstering the chances for the possible existence of present day Martian microbes.

Utilizing spectroscopic measurements and imaging gathered by NASA’s Mars Reconnaissance Orbiter (MRO), researchers found the first strong evidence confirming that briny water flows on the Red Planet today along dark streaks moving downhill on crater slopes and mountain sides, during warmer seasons.

“Mars is not the dry, arid planet that we thought of in the past. Today we announce that under certain circumstances, liquid water has been found on Mars,” said Jim Green, NASA Planetary Science Director at NASA Headquarters, at a media briefing held today, Sept 28.

“When you look at Earth, water is an essential ingredient. Everywhere we go where there’s liquid water, whether its deep in the Earth or in the arid regions, we find life. This is tremendously exciting.”

“We haven’t been able to answer the question – does life exist beyond Earth? But following the water is a critical element of that. We now have great opportunities to be in the right locations on Mars to thoroughly investigate that,” Green elaborated.

“Water! Strong evidence that liquid water flows on present-day Mars,” NASA officials tweeted about the discovery.

The evidence comes in the form of the detection of mysterious dark streaks, as long as 100 meters, showing signatures of hydrated salt minerals periodically flowing in liquid water down steep slopes on the Red Planet that “appear to ebb and flow over time.”

The source of the water is likely from the shallow subsurface or possibly absorbed from the atmosphere.

Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars. The image is produced by draping an orthorectified (RED) image (ESP_031059_1685) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona).

Water is a key prerequisite for the formation and evolution of life as we know it. So the new finding significantly bolsters the chances that present day extant life could exist on the Red Planet.

“Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington.

“This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

“This increases the chance that life could exist on Mars today,” noted Grunsfeld.

The data were gathered by and the conclusions are based on using two scientific instruments – the high resolution imaging spectrometer on MRO known as High Resolution Imaging Science Experiment (HiRISE), as well as MRO’s mineral mapping Compact Reconnaissance Imaging Spectrometer for Mars (CRISM).

The mysterious dark streaks of downhill flows are known as recurring slope lineae (RSL).

They were first detected in 2010 at dozens of sites on the sun facing slopes of deep craters by Lujendra Ojha, then a University of Arizona undergraduate student.

The new finding is highly significant because until today’s announcement, there was no strong evidence that liquid water could actually exist on the Martian surface because the atmospheric pressure was thought to be far too low – its less than one percent of Earth’s.

The flow of water is occasional and not permanent, seasonally variable and dependent on having just the right mix of atmospheric, temperature and surface conditions with salt deposits on Mars.

Portions of Mars were covered with an ocean of water billions of years ago when the planet was far warmer and more hospitable to life. But it underwent a dramatic climate change some 3 billion years ago and lost most of that water.

The RSL with flowing water appear in at least three different locations on Mars – including Hale crater, Horowitz crater and Palikir crater – when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius). They appear during warm seasons, fade in cooler seasons and disappear during colder times.

Pure surface water ice would simply sublimate and evaporate away as the temperature rises. Mixing in surface salts lowers the melting point of ice, thereby allowing the water to potentially liquefy on Mars surface for a certain period of time rather than sublimating rapidly away.

“These are dark streaks that form in late spring, grow through the summer and then disappear in the fall,” said Michael Meyer lead scientist for the Mars Exploration Program at NASA Headquarters, at the media briefing.

Years of painstaking effort and laboratory work was required to verify and corroborate the finding of flowing liquid water.

“It took multiple spacecraft over several years to solve this mystery, and now we know there is liquid water on the surface of this cold, desert planet,” said Meyer. “It seems that the more we study Mars, the more we learn how life could be supported and where there are resources to support life in the future.”

The dark, narrow streaks flowing downhill on Mars at sites such as this portion of Horowitz Crater are inferred to be formed by seasonal flow of water on modern-day Mars. The streaks are roughly the length of a football field. These dark features on the slopes are called "recurring slope lineae" or RSL.

Along with the media announcement, the researchers published their findings today in a refereed scientific paper in the Sept. 28 issue of Nature Geoscience.

“We found the hydrated salts only when the seasonal features were widest, which suggests that either the dark streaks themselves or a process that forms them is the source of the hydration. In either case, the detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks,” said Lujendra Ojha, now at the Georgia Institute of Technology (Georgia Tech) in Atlanta, and lead author of the Sept. 28 publication in Nature Geoscience.

The scientists “interpret the spectral signatures as caused by hydrated minerals called perchlorates.”

Ojha said the chemical signatures from CRISM were most consistent with the detection of mixtures of magnesium perchlorate, magnesium chlorate and sodium perchlorate, based on lab experiments.

“Some perchlorates have been shown to keep liquids from freezing even when conditions are as cold as minus 94 degrees Fahrenheit (minus 70 Celsius).”

Perchlorates have previously been detected in Martian soil by two of NASA’s surface missions – the Phoenix lander and the Curiosity rover. There is also some evidence that NASA’s Viking missions in the 1970s measured signatures of these salts.

On Earth concentration of perchlorates are found in deserts.

This also marks the first time perchlorates have been identified from Mars orbit.

NASA’s overriding agency wide goal is to send humans on a ‘Journey to Mars’ in the 2030s.

So NASA astronaut Mark Kelly exclaimed that he was also super excited about the findings, from his perch serving as Commander aboard the International Space Station (ISS), where he is a member of the first ever “1 Year ISS Mission Crew” aimed at learning how the human body will adapt to the long term missions required to send astronauts to Mars and back.

“One reason why NASA’s discovery of liquid water on #Mars is so exciting: we know anywhere there’s water on Earth, there’s some form of life,” Kelly tweeted today from on board the ISS, upon hearing today’s news.

The discovery of liquid water on Mars could also be a boon to future astronauts who could use it as a natural resource to ‘live off the land’ for sustenance and to make rocket fuel.

“If going to Mars on my Year In Space, I’d arrive soon to find water! H20 > rocket fuel, which means I could find my way back home too!,” Kelly wrote on his Facebook page.

“When most people talk about water on Mars, they’re usually talking about ancient water or frozen water,” Ojha explained.

“Now we know there’s more to the story. This is the first spectral detection that unambiguously supports our liquid water-formation hypotheses for RSL.”

Matt Damon of ‘The Martian’ Explains NASA’s Journey to Mars – ISS Crew Previews Film on Orbit

The excitement is building for the worldwide movie premiere of ‘The Martian’ on Oct. 2.

Based on the bestselling book by Andy Weir, ‘The Martian’ tells the story of how NASA astronaut Mark Watney, played by Matt Damon, is accidentally stranded on the surface of Mars during a future manned expedition, after a sudden and unexpectedly fierce dust storm forces the rest of the crew to quickly evacuate after they believe he is dead.

In the video above, Matt Damon discusses NASA’s ongoing real life efforts focused on turning science fiction dreams into reality and sending astronauts to Mars.

Watney actually survived the storm but lost contact with NASA. The film recounts his ingenious years long struggle to survive, figure out how to tell NASA he is alive and send a rescue crew before he starves to death on a planet where nothing grows. Watney’s predicament is a survival lesson to all including NASA.

‘The Martian’ was written by Andy Weir in 2010 and has now been produced as a major Hollywood motion picture starring world famous actor Matt Damon and directed by the world famous director Ridley Scott from 20th Century Fox.

NASA’s overriding strategic goal is to send humans on a ‘Journey to Mars’ by the 2030s.

‘The Martian’ is a rather realistic portrayal of how NASA might accomplish the ‘Journey to Mars.’

“Sending people to Mars and returning them safely is the challenge of a generation,” says Damon in the video.

“The boot prints of astronauts will follow the rover tracks [of NASA’s Curiosity rover] thanks to innovations happening today.”

“NASA’s Journey to Mars begins on the International Space Station (ISS) .. where we are learning how humans can thrive over long periods without gravity.”

The current six person crew serving aboard the ISS even got a sneak preview of The Martian this past weekend!

Gleeful NASA astronaut Scott Kelly, commander of the Expedition 45 crew, just tweeted a photo of the crew watching ‘The Martian’ while soaring some 250 miles (400 kilometers) above Earth.

“Watched @MartianMovie on @Space_Station last night! Today working towards our #JourneyToMars during my #YearInSpace!” tweeted NASA astronaut Scott Kelly.

Kelly comprises one half of the first ever ‘1 Year ISS Crew’ along with Russian cosmonaut Mikhail Kornienko, aimed at determining the long term physical and psychological effects on the human body of people living and working in the weightlessness of space.

The 1 Year ISS mission is an important data gathering milestone on the human road to Mars since the round trip time to the Red Planet and back will take approximately 3 years or more.

In order to send astronauts to the Red Planet, NASA is now developing the mammoth Space Launch System (SLS) heavy lift booster and the Orion crew capsule to propel astronauts farther than ever before on the Journey to Mars.

The first unmanned test flight of SLS/Orion is slated for Nov. 2018. The first manned flight could occur between 2021 and 2023 – read my new report here.

“The Journey to Mars will forever change our history books … and expand our human presence deeper into the solar system,” says Damon.

THE MARTIAN features a star studded cast that includes Matt Damon, Jessica Chastain, Kristen Wiig, Kate Mara, Michael Pena, Jeff Daniels, Chiwetel Ejiofor, and Donald Glover.

“NASA has endorsed “The Martian’” Jim Green, NASA’s Director of Planetary Sciences, told Universe Today. Green served as technical consultant on the film.

I have read the book (I’m a professional chemist) and highly recommend it to everyone.

The Martian is all about how Watney uses his botany and chemistry skills to “Science the Sh.. out of it” to grow food and survive.

Learning how to live of the land will be a key hurdle towards enabling long term space voyages.

Kelly and his ISS cremates took a big first step towards putting that theory into practice when they recently grew, harvested and ate the first space grown NASA lettuce on the ISS using the Veggie experimental rack – detailed in my recent story here.

NASA’s SUV-sized Curiosity rover has arrived at a beautiful Martian vista displaying a huge deposit of magnificently petrified sand dunes that look remarkably like some commonly found on Earth and native to the deserts of the U.S. Southwest.

The dunes are keenly fascinating to Red Planet researchers as the NASA robot celebrates 1100 fabulous Sols of exploration and discovery on Mars and contemplates plans for the next drill campaign later this month. See dune mosaic above and our Sol 1100 mosaic below.

The petrified sand dunes were discovered amongst an area of dark sandstone along a ridge at the lower slope of Mars’ Mount Sharp. They are now being explored in detail by the six wheeled rover in a geologic feature dubbed the Stimson unit.

“The team is considering where to drill next within the Stimson sandstone and we are looking for the best light toned areas to check for mineralogical signs of water-rock reaction,” says John Bridges, rover team member from the University of Leicester, England, in the latest mission update from today, September 12, 2015.

Curiosity also discovered large-scale crossbedding in the sandstone that were formed by the action of Martian winds.

“This sandstone outcrop — part of a geological layer that Curiosity’s science team calls the Stimson unit — has a structure called crossbedding on a large scale that the team has interpreted as deposits of sand dunes formed by wind,” according to the rover team.

So Curiosity was commanded by her handlers back on Earth to capture an array of high resolution imagery as part of detailed investigation of the area for up close and contact science.

Dozens of images were taken with the pair of high resolution Mastcam color cameras on the robots mast and combined into the panoramic scene show above and another shown below with a scalebar the length of a tall human, 6.6 feet or 200 centimeters.

The images were taken on Aug. 27, 2015, corresponding to Sol 1087 of the rover’s work on Mars, using both the 34 millimeter-focal-length lens and the 100 mm millimeter-focal-length telephoto Mastcam camera lenses that function as Curiosity’s left and right eyes.

The panorama spans the Martian terrain looking from the east, at left, to the south-southwest at right.

“Some of the dark sandstone in the area …. shows texture and inclined bedding structures characteristic of deposits that formed as sand dunes, then were cemented into rock” say officials.

“Sets of bedding laminations lie at angles to each other.”

Since taking the panorama in late August, the team has driven Curiosity around the area to collect more measurements with her state of the art science instruments.

Later this month, Curiosity will drill into an outcrop at the Stimson unit sandstone for collection and feed it for analysis into the pair of on board chemistry labs – SAM and CheMin- located inside the rover’s belly.

Curiosity already carried out initial contact science in the area by extending the robotic arm to rock targets for investigation with the arm mounted instruments, including the MAHLI camera and APXS spectrometer.

Curiosity “investigated an outcrop of the Stimson unit … and conducted successful contact science,” says Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

Scientists will select the Stimson drill target soon.

Why explore outcrops at Stimson?

“The Stimson unit overlies a layer of mudstone that was deposited in a lake environment. Curiosity has been examining successively higher and younger layers of Mount Sharp, starting with the mudstone at the mountain’s base, for evidence about changes in the area’s ancient environment.”

Curiosity’s prior drill campaign was recently conducted at the “Buckskin” outcrop target in early August 2015. Buckskin was very notable for being the first high silica rock drilling target of the mission.

Stimson and Buckskin sit at the base of Mount Sharp, a huge layered mountain that dominates the center of the 96 mile-wide (154 kilometers-wide) Gale Crater landing site.

Exploring the sedimentary 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.

Curiosity recently celebrated 1000 Sols of exploration on Mars on May 31, 2015 – detailed here with our Sol 1000 mosaic by Marco Di Lorenzo and Ken Kremer also featured at Astronomy Picture of the Day on June 13, 2015.

As of today, Sol 1102, September 12, 2015, she has driven some 6.9 miles (11.1 kilometers) kilometers and taken over 268,000 amazing images.

Curiosity has already accomplished her primary objective of discovering a habitable zone on the Red Planet – at the Yellowknife Bay area – that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

When it comes to space exploration it’s resoundingly clear that rock band ‘One Direction’ is headed in the right direction – To Infinity and Beyond! – with the release of their new NASA themed music video ‘Drag Me Down.’

The new single – ‘Drag Me Down’ – by the world famous boy band is out now and out of this world!

Just click on the Vevo video above and enjoy their musical tour through space exploration themed videos filmed on location at NASA facilities, including the Johnson Space Center – home to astronauts training to explore ‘Where No One Has Gone Before.’

Over 18,100,000 views so far!! Millions of eyeballs exposed to NASA activities like never before!

As you’ll see in the video (published on Aug. 20) the quartet got a first hand look at a host of NASA’s cutting edge technology and hardware like NASA’s Orion deep space crew capsule that’s destined to propel our astronauts back to deep space and explore wondrous destinations including the Moon, asteroids and the Red Planet, as part of the agency’s ‘Journey to Mars’ initiative.

Motivating our young people to study and excel in math, science, engineering, technology and the arts is what it’s all about to inspire the next generation of explorers and advance all humanity to fulfilling and prosperous lives.

“#DragMeDownMusicVideo @space_station Gravity can’t drag me down! Great to see @NASA inspire our next gen #YearInSpace,” tweeted NASA astronaut Scott Kelly currently working aboard the International Space Station.

Lets join “One Direction’s” space tour.

So the guys donned NASA’s spacesuits as they began ‘training’ to fly aboard NASA’s Orion spaceship.

But first they rollick with the astronauts T-38 training jets which are used by real-life astronauts to practice spacecraft operations at supersonic speeds up to Mach 1.6 and experience blistering accelerations of more than seven Gs!

tumblr_inline_ntg4daeKad1tzhl5u_500

Here we join Louis to rove around Johnson Space Center in NASA’s Space Exploration Vehicle that will one day be used for awe-inspiring interplanetary journey’s to the surface of alien bodies like the moon, near-Earth asteroids and Mars!

Even though Louis is roving around Johnson Space Center in our Space Exploration Vehicle, its intended destination is quite different. The SEV will be used for in-space missions and for surface explorations of planetary bodies, including near-Earth asteroids and Mars!

Wouldn’t you like to join Louis!

Meanwhile Harry got to hang out with Robonaut at the Johnson Space Center during the filming of the music video.

tumblr_inline_ntg3q7Xlt51tzhl5u_500

Simultaneously the Robonauts twin brother, Robonaut 2, is hanging out in space right now with other humans. Robonaut 2 is working side-by-side with NASA astronauts Scott Kelly and Kjell Lindgren and the rest of the six man crew floating aboard the International Space Station and soaring some 250 miles (400 kilometers) overhead.

“Going where the risks are too great for people, robots will make it so we never get ‘dragged down’!” says NASA.

“Currently living in space, @StationCDRKelly is 1 of 6 people that literally cannot be dragged down. #DragMeDown,” NASA tweeted.

I’ve been a fan of ‘One Direction’ and now nothing will ‘hold me back’ following #DragMeDown.

And don’t forget that you can watch Commander Scott Kelly and his five international crew mates on a regular basis as they soar overhead. Just click on NASA’s Spot the Station link and plug in your location.

And make sure you sign up to ‘Send Your Name to Mars’ on InSight – NASA’s next Mars Lander. The deadline is Sept 8 – sign up details in my story here.

Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

Here’s what the real Orion EFT-1 looked like after the mission was successfully completed and it was recovered from splashdown in the Pacific Ocean.

Right now NASA is building the next Orion.

If you desire to be aboard a future Orion, don’t let anything ‘Drag You Down.’

And tell Congress and the White House to ‘Support Full Funding for NASA!’ – – Because Congress has significantly slashed funding for the commercial crew capsules in the upcoming 2016 Fiscal Year budget!

NASA’s Curiosity rover has snapped a stunningly beautiful, one of a kind ‘belly selfie’ amidst the painstaking ‘Buckskin’ drill campaign at the Martian mountain base marking the third anniversary since her touchdown on the Red Planet.

The unique self portrait was taken from a low-angle for the first time and shows the six wheeled rover at work collecting her seventh drilled sample at the ‘Buckskin’ rock target earlier this month in the “Marias Pass” area of lower Mount Sharp.

‘Buckskin’ is also unique in a fabulously scientifically way because the rover discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.

The low camera angle is what enables the awesome Buckskin belly selfie. It’s a distinctively dramatic view and actually stitched from 92 images captured by the Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, or Sol 1065 of the mission.

The high resolution MAHLI color camera is located on the end of the 7 foot-long (2.1 meter-long) robotic arm.

This version of a self-portrait of NASA's Curiosity Mars rover at a drilling site called "Buckskin" is presented as a stereographic projection, which shows the horizon as a circle.

Indeed the car-sized rover has taken spectacular selfies several times before during her three year long trek across the Martian surface, since the August 2012 landing inside Mars’ Gale Crater. But for those past selfies the MAHLI camera was hoisted higher to give the perspective of looking somewhat downward and showing the rovers top deck and trio of sample inlet ports.

In this case, the rover team specifically commanded Curiosity to position “the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity,” said NASA officials.

Two patches of gray colored powdered rock material drilled from Buckskin are visible in the selfie scene, in front of the rover.

“The patch closer to the rover is where the sample-handling mechanism on Curiosity’s robotic arm dumped collected material that did not pass through a sieve in the mechanism. Sieved sample material was delivered to laboratory instruments inside the rover. The patch farther in front of the rover, roughly triangular in shape, shows where fresh tailings spread downhill from the drilling process.”

Prior selfies were taken at the “Rocknest” (http://photojournal.jpl.nasa.gov/catalog/PIA16468), “John Klein” (http://photojournal.jpl.nasa.gov/catalog/PIA16937), “Windjana” (http://photojournal.jpl.nasa.gov/catalog/PIA18390) and “Mojave” drill sites.

Basically in the Sol 1065 belly selfie at “Buckskin” we see the underbelly of the rover and all six wheels along with a complete self portrait.

On several prior occasions, MAHLI was used to image just the underbelly and wheels to aid in inspecting the wheels to look for signs of damage inflicted by sharp-edged Martian rocks poking holes in the aluminum wheels.

Each wheel measures 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. And the MAHLI monitoring images have shown the effects of increasing wear and tear that ultimately forced the rover drivers to alter Curiosity’s driving route on the crater floor in favor of smoother and less rocky terrain imparting less damage to the critical wheels.

If you take a close look at the new selfie up top, you’ll see a small rock stuck onto Curiosity’s left middle wheel (on the right in this head-on view). The rock was seen also in prior wheel monitoring images taken three weeks ago.

“The selfie at Buckskin does not include the rover’s robotic arm beyond a portion of the upper arm held nearly vertical from the shoulder joint. With the wrist motions and turret rotations used in pointing the camera for the component images, the arm was positioned out of the shot in the frames or portions of frames used in this mosaic,” according to officials.

The drilling campaign into “Buckskin” was successfully conducted on Sol 1060 (July 30, 2015) at the bright toned “Lion” outcrop to a full depth of about 2.6 inches (6.5 centimeters) and approximately 1.6 cm (0.63 inch) diameter.
