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

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

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

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

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

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

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

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

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

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

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

How long will the journey to Mount Sharp take?

“Perhaps about a year,” Erickson told me.

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

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

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

So far the terrain has not been problematical.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Curiosity Sets Record Pace for Longest Drive Yet on Mars

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

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

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

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

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

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

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

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

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

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

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

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

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

“This will increase our ability to drive.”

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

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

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

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

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

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

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

“This will increase the productivity!”

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Curiosity rover Embarks on Epic Trek To Mount Sharp

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Every once in a while when the time is just right and no one is looking, Curiosity’s Earthly handlers allow her some night time Martian delights.

In this case a pair of rising and setting celestial events bookend another magnificent week in humankinds exploration of the Red Planet – courtesy of NASA.

This past week NASA’s Curiosity rover captured esthetically stunning imagery of Phobos rising and Our Sun setting on Mars.

Phobos is the larger of Mars pair of tiny moons. The other being Diemos.

On June 28, (Sol 317) Curiosity aimed her navigation camera straight overhead to captured a breathtaking series of 86 images as Phobos was ascending in the alien evening sky shortly after sunset.

NASA combined these raw images taken over about 27 minutes into a short movie clip, sped up from real time.

Video Caption: ‘Phobos Rising’ – This movie clip shows Phobos, the larger of the two moons of Mars, passing overhead, as observed by NASA’s Mars rover Curiosity in a series of images centered straight overhead starting shortly after sunset. Phobos first appears near the lower center of the view and moves toward the top of the view. The images were taken on June 28, 2013. The apparent ring is an imaging artifact.

The pockmarked and potato shaped moon measures about 26.8 × 22.4 × 18.4 kilometers.

Phobos orbits barely some 6,000 km (3,700 mi) above the Martian surface. One day far in the future, it will crash and burn.

On June 22, Curiosity snapped an evocative series of Martian sunset photos as Sol set behind the eroded rim of Gale Crater – see below.

In the 2030’s, Humans may visit Phobos first before setting foot on the much more technically challenging Red Planet.

In the meantime, enjoy the otherworldly view!

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Curiosity Gets Set for Epic Drive after Laser Blasting Mars Watery Secrets

Ten months after her breathtaking touchdown on the Red Planet, NASA’s Curiosity rover is nearly set to embark on an epic drive like no other in space history to the slopes of mysterious Mount Sharp – looming supreme inside Gale Crater and the primary mission objective.

But not before the robot completes a few last critical science tasks to more fully illuminate the potential for the origin of Martian microbes in the habitable zone discovered at the work-site of her first penetrations into Mars water altered surface.

The rover science team has chosen a trio of final targets to investigate around the shallow basin of Yellowknife Bay, that resembles a dried out lakebed, where Curiosity has toiled for the past six months, drilled twice into the mudstone outcrops at ‘John Klein’ and ‘Cumberland’ and repeatedly fired her powerful science laser.

Curiosity will revisit a pair of intriguing outcrops named ‘Point Lake’ and ‘Shaler’ that the rover briefly investigated before arriving at ‘John Klein’, said Joy Crisp of JPL, Curiosity’s deputy project scientist, at a media briefing.

“Shaler might be a river deposit. Point Lake might be volcanic or sedimentary. A closer look at them could give us better understanding of how the rocks we sampled with the drill fit into the history of how the environment changed.”

Curiosity will employ nearly all her science instruments to study the outcrops – except the drill.

“It’s highly unlikely to drill at ‘Point Lake’ and ‘Shaler’ because we want to get driving,” Crisp told Universe Today.

“We might drill somewhere along the way to Mount Sharp depending on whether we find something compelling.”

Researchers will also use the DAN (Dynamic Albedo of Neutrons) instrument to look for traces of mineral bound water – in the form of hydrogen – at the boundary between bedrock areas of mudstone and sandstone.

Thereafter, Curiosity’s handlers will command the 1 ton behemoth to begin the drive to the lower reaches of Mount Sharp which lies about 6 miles (10 kilometers) distant – as the Martian crow flies.

Mount Sharp rises about 3.4 miles (5.5 km) from the center of Gale Crater. It’s taller than Mount Ranier in Washington State.

Billions of years of Mars geologic history are preserved in the sedimentary layers of Mount Sharp – along with potential signatures of the chemical ingredients of life.

“The drive will start in a few weeks,” said Curiosity Project Manager Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. at the briefing.

But the team will be on the lookout for targets of opportunity along the way.

“We are on a mission of exploration. If we come across scientifically interesting areas, we are going to stop and examine them before continuing the journey,” Erikson added.

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

It could take nearly a year to arrive at Mount Sharp. And Curiosity must pass through a potentially treacherous dune field to get there – see NASA JPL route map above.

“We are looking for the best path though,” said Erickson.

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

“We have a real desire to get to Mount Sharp because there we see variations in the mineralogy as we go up from the base to higher levels and a change in the record of the environment,” said Crisp.

Analysis of the initial gray colored, powdery ‘John Klein’ sample by Curiosity’s pair of onboard chemistry labs – SAM & Chemin – revealed that this location on Mars was habitable in the past and possesses the key chemical ingredients – such as clay minerals – required to support microbial life forms- thereby successfully accomplishing the key science objective of the mission and making a historic discovery long before even arriving at destination Mount Sharp.

Besides the science measurements, researchers also learned lot about how to operate the complex drilling and sample delivery mechanisms much more efficiently for the second drilled rock sample.

The sieved and pulverized Cumberland sample was delivered in about a quarter of the time compared to the John Klein sample – accomplished at a deliberately measured and cautious pace.

Analysis of the “Cumberland” powder is currently in progress. The goal is to determine how it compares chemically and to confirm the results found at ‘John Klein.’

“No results from Cumberland are available yet,” said Crisp.

The robot used the powerful million watt ChemCam laser to blast into the Cumberland drill hole and gray tailings scattered on the surface to glean as much insight and measurements of the chemical composition and transformation by water as possible before departing.

Curiosity has just arrived at “Point Lake’. Stay tuned for my next Curiosity story.

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

Opportunity Rover Discovers Martian Habitable Zone Favorable for Pre-biotic Chemistry

Opportunity captures a panoramic view of the road ahead to the raised rim of Solander Point (at left) which is some 0.8 mile (1.3 km) away. Arrival is targeted for August. It features a thick strata of ancient rocks which may harbor clay minerals indicative of a habitable zone and northerly tilted slopes to maximize power generation from the solar panels during upcoming 6th winter season at Endeavour crater rim.

On the cusp of the 10th anniversary since launching to the Red Planet, NASA’s long lived Opportunity rover has discovered a habitable zone on Mars that once coursed with ‘drinkable water’ and possesses the chemical ingredients necessary to support a path to potential Martian microbes.

At a rock called “Esperance”, Opportunity found a cache of phyllosilicate clay minerals that typically form in neutral, drinkable water that is not extremely acidic or basic.

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

And despite her advancing age Opportunity remains healthy after surviving in excess of an incredible 3333 Sols, or days, trekking across the alien and ever harsh Martian crater plains.

Furthermore the intrepid robot just sat sail on a southerly course for a new destination called “Solander Point” where researches hope to find more even evidence of habitable environments since they already spotted deeper stakes of ancient rocks transformed by water eons ago. See our current photo mosaics showing Solander Point as Opportunity roves across the crater floor – above and below by Marco Di Lorenzo and Ken Kremer.

After weeks of trying, the rover deployed the robotic arm to drill at a sweet spot inside “Esperance” and collected convincing X-Ray spectroscopic data in the area she just investigated in May 2013 around the eroded rim of giant Endeavour Crater.

“Esperance is rich in clay minerals and shows powerful evidence of water alteration,” Squyres elaborated.

“This is the most powerful evidence we found for neutral pH water.”

“Clay minerals only tend to form at a more neutral pH. This is water you could drink,” Squyres gushed.

These finding represent the most favorable conditions for biology that Opportunity has yet seen in the rock histories it has encountered after nearly a decade roving the Red Planet.

“This is water that was much more favorable for things like pre-biotic chemistry – the kind of chemistry that could lead to the origin of life,” Squyres stated.

Esperance is unlike any rock previously investigated by Opportunity; rich in aluminum, which is strongly indicative of clay minerals, perhaps like montmorillonite.

Most rocks inspected to date by Opportunity were formed in an environment of highly acidic water that is extremely harsh to most life forms.

“If you look at all of the water-related discoveries that have been made by Opportunity, the vast majority of them point to water that was a very low pH – it was acid,” Squyres explained.

Esperance was found on ‘Cape York’, a hilly segment of the western rim of Endeavour crater which spans 14 miles (22 km) across. The robot arrived at the edge of Endeavour crater in mid-2011 and will spend her remaining life driving around the scientifically rich crater rim segments.

The pale rock in the upper center of this image, about the size of a human forearm, includes a target called "Esperance," which was inspected by NASA's Mars Exploration Rover Opportunity. Data from the rover's alpha particle X-ray spectrometer (APXS) indicate that Esperance's composition is higher in aluminum and silica, and lower in calcium and iron, than other rocks Opportunity has examined in more than nine years on Mars. Preliminary interpretation points to clay mineral content due to intensive alteration by water.

NASA’s new Curiosity rover also recently discovered clay minerals and a habitable environment at Gale Crater – on the other side of Mars – stemming from a time when Mars was warmer and wetter billions of years ago.

Over time Mars became the cold and dry place it is today. Scientists hope the rovers provide clues to Mars dramatic transformation.

The solar powered rover is now driving as quick as possible to reach the northerly tilled slopes of ‘Solander Point’ in August, before the onset of the next Martian winter.

‘Solander Point’ offers a much taller stack of geological layering than ‘Cape York.’ Both areas are raised segments of the western rim of Endeavour Crater.

“There’s a lot to explore there. In effect, it’s a whole new mission,” said Ray Arvidson, the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

Opportunity and her twin “Spirit” were launched to Mars on planned 90 day missions.

Both rovers have far exceeded everyone’s wildest expectations. Spirit endured more than 6 years inside Gusev Crater until succumbing to the bone chilling Martian winter in 2011.

Opportunity has lasted more than 37 times beyond the three month “warranty”.

“This is like your car not lasting 200,000 miles, or even a million miles. You’re talking about a car that lasts 2 million miles without an oil change,” Callas said. “At this point, how long Opportunity lasts is anyone’s guess.”

“Remember, the rover continues to operate in a very hostile environment, where we have extreme temperature changes every day, and the rover could have a catastrophic failure at anytime,” said John Callas, of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for the Mars Exploration Rover Project.

“So every day is a gift.”

Boeing Commercial Space Taxi and Atlas V Launcher Move Closer to Blastoff

The next time that American astronauts launch to space from American soil it will surely be aboard one of the new commercially built “space taxis” currently under development by a trio of American aerospace firms – Boeing, SpaceX and Sierra Nevada Corp – enabled by seed money from NASA’s Commercial Crew Program (CCP).

Boeing has moved considerably closer towards regaining America’s lost capability to launch humans to space when the firm’s privately built CST-100 crew capsule achieved two key new milestones on the path to blastoff from Florida’s Space Coast.

The CST-100 capsule is designed to carry a crew of up to 7 astronauts on missions to low-Earth orbit (LEO) and the International Space Station (ISS) around the middle of this decade.

Boeing’s crew transporter will fly to space atop the venerable Atlas V rocket built by United Launch Alliance (ULA) from Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

The Boeing and ULA teams recently completed the first wind tunnel tests of a 7 percent scale model of the integrated capsule and Atlas V rocket (photo above) as well as thrust tests of the modified Centaur upper stage.

The work is being done under the auspices of NASA’s Commercial Crew Integrated Capability (CCiCap) initiative, intended to make commercial human spaceflight services available for both US government and commercial customers, such as the proposed Bigelow Aerospace mini space station.

Since its maiden liftoff in 2002, the ULA Atlas V rocket has flawlessly launched numerous multi-billion dollar NASA planetary science missions like the Curiosity Mars rover, Juno Jupiter orbiter and New Horizons mission to Pluto as well as a plethora of top secret Air Force spy satellites.

But the two stage Atlas V has never before been used to launch humans to space – therefore necessitating rigorous testing and upgrades to qualify the entire vehicle and both stages to meet stringent human rating requirements.

“The Centaur has a long and storied past of launching the agency’s most successful spacecraft to other worlds,” said Ed Mango, NASA’s CCP manager at the agency’s Kennedy Space Center in Florida. “Because it has never been used for human spaceflight before, these tests are critical to ensuring a smooth and safe performance for the crew members who will be riding atop the human-rated Atlas V.”

The combined scale model CST-100 capsule and complete Atlas V rocket were evaluated for two months of testing this spring inside an 11- foot diameter transonic wind tunnel at NASA’s Ames Research Center in Moffett Field, Calif.

“The CST-100 and Atlas V, connected with the launch vehicle adaptor, performed exactly as expected and confirmed our expectations of how they will perform together in flight,” said John Mulholland, Boeing vice president and program manager for Commercial Programs.

Testing of the Centaur stage centered on characterizing the flow of liquid oxygen from the oxygen tank through the liquid oxygen-feed duct line into the pair of RL-10 engines where the propellant is mixed with liquid hydrogen and burned to create thrust to propel the CST-100 into orbit.

Boeing is aiming for an initial three day manned orbital test flight of the CST-100 during 2016, says Mulholland.

But that date is dependent on funding from NASA and could easily be delayed by the ongoing sequester which has slashed NASA’s and all Federal budgets.

Chris Ferguson, the commander of the final shuttle flight (STS-135) by Atlantis, is leading Boeing’s flight test effort.

Boeing has leased one of NASA’s Orbiter Processing Facility hangers (OPF-3) at the Kennedy Space Center (KSC) for the manufacturing and assembly of its CST-100 spacecraft.

Mulholland told me previously that Boeing will ‘cut metal’ soon. “Our first piece of flight design hardware will be delivered to KSC and OPF-3 around mid 2013.”

NASA’s CCP program is fostering the development of the CST-100 as well as the SpaceX Dragon and Sierra Nevada Dream Chaser to replace the crew capability of NASA’s space shuttle orbiters.

The Atlas V will also serve as the launcher for the Sierra Nevada Dream Chaser space taxi.

Since the forced retirement of NASA’s shuttle fleet in 2011, US and partner astronauts have been 100% reliant on the Russians to hitch a ride to the ISS aboard the Soyuz capsules – at a price tag exceeding $60 Million per seat.

Simultaneously on a parallel track NASA is developing the Orion crew capsule and SLS heavy lift booster to send humans to the Moon and deep space destinations including Asteroids and Mars.
