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

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.

“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,” said Grotzinger.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The robot remains in excellent health.

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

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

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

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. Credit: NASA/JPL-Caltech

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.

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.

Final Construction Starts for Europe’s 2016 Methane Sniffing Mars Mission

Has life ever existed on Mars? Or anywhere beyond Earth?

Answering that question is one of the most profound scientific inquiries of our time.

Europe and Russia have teamed up for a bold venture named ExoMars that’s set to blast off in search of Martian life in about two and a half years.

Determining if life ever originated on the Red Planet is the primary goal of the audacious two pronged ExoMars missions set to launch in 2016 & 2018 in a partnership between the European and Russian space agencies, ESA and Roscosmos.

In a major milestone announced today (June 17) at the Paris Air Show, ESA signed the implementing contract with Thales Alenia Space, the industrial prime contractor, to start the final construction phase for the 2016 Mars mission.

“The award of this contract provides continuity to the work of the industrial team members of Thales Alenia Space on this complex mission, and will ensure that it remains on track for launch in January 2016,” noted Alvaro Giménez, ESA’s Director of Science and Robotic Exploration.

The ambitious 2016 ExoMars mission comprises of both an orbiter and a lander- namely the methane sniffing Trace Gas Orbiter (TGO) and the piggybacked Entry, Descent and Landing Demonstrator Module (EDM).

ExoMars 2016 will be Europe’s first spacecraft dispatched to the Red Planet since the 2003 blast off of the phenomenally successful Mars Express mission – which just celebrated its 10th anniversary since launch.

Methane (CH4) gas is the simplest organic molecule and very low levels have reportedly been detected in the thin Martian atmosphere. But the data are not certain and its origin is not clear cut.

Methane could be a marker either for active living organisms today or it could originate from non life geologic processes. On Earth more than 90% of the methane originates from biological sources.

The ExoMars 2016 orbiter will investigate the source and precisely measure the quantity of the methane.

The 2016 lander will carry an international suite of science instruments and test European landing technologies for the 2nd ExoMars mission slated for 2018.

The 2018 ExoMars mission will deliver an advanced rover to the Red Planet’s surface. It is equipped with the first ever deep driller that can collect samples to depths of 2 meters where the environment is shielded from the harsh conditions on the surface – namely the constant bombardment of cosmic radiation and the presence of strong oxidants like perchlorates that can destroy organic molecules.

ExoMars was originally a joint NASA/ESA project until hefty cuts to NASA’s budget by Washington DC politicians forced NASA to terminate the agencies involvement after several years of detailed work.

Thereafter Russia agreed to take NASA’s place and provide the much needed funding and rockets for the pair of planetary launches scheduled for January 2016 and May 2018.

NASA does not have the funds to launch another Mars rover until 2020 at the earliest – and continuing budget cuts threaten even the 2020 launch date.

NASA will still have a small role in the ExoMars project by funding several science instruments.

The ExoMars missions along with NASA’s ongoing Curiosity and Opportunity Mars rovers will pave the way for Mars Sample Return missions in the 2020’s and eventual Humans voyages to the Red Planet in the 2030’s.

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 established a new American driving record for a vehicle on another world on May 15, 2013 (Sol 3309) and made history by driving ahead from this point at Cape York. This navcam mosaic shows the view forward to her next destinations of Solander Point and Cape Tribulation along the lengthy rim of huge Endeavour crater spanning 14 miles (22 km) in diameter.

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.”

10 Years & Top 10 Discoveries from Marvelous Mars Express

This week marks the 10th anniversary since the launch of the European Space Agencies’ (ESA) Mars Express orbiter from the Baikonur Cosmodrome in Russia on June 2, 2003 and a decade of ground breaking science discoveries at the Red Planet.

2003 was a great year for Mars exploration as it also saw the dual liftoffs of NASA’s now legendary rovers Spirit & Opportunity from Cape Canaveral in Florida.

The immense quantity and quality of science data returned from Mars Express -simultaneously with Spirit and Opportunity – has completely transformed our understanding of the history and evolution of the Red Planet.

All three spacecraft have functioned far beyond their original design lifetime.

Earth’s exploration fleet of orbiters, landers and rovers have fed insights to each other that vastly multiplied the science output compared to working solo during thousands and thousands of bonus Sols at Mars.

The image was taken on 4 January 2013, during orbit 11467, and shows a close up view of the central ‘pit’ of this crater, which likely formed by a subsurface explosion as the heat from the impact event rapidly vapourised water or ice lying below the surface.

Mars Express derived its name from an innovative new way of working in planetary space science that sped up the development time and cut costs in the complex interactive relationships between the industrial partners, space agencies and scientists.

Indeed the lessons learned from building and operating Mars Express spawned a sister ship, Venus Express that also still operates in Venusian orbit.

Mars Express (MEX) achieved orbit in December 2003.

MEX began science operations in early 2004 with an array of seven instruments designed to study all aspects of the Red Planet, including its atmosphere and climate, and the mineralogy and geology of the surface and subsurface with high resolution cameras, spectrometers and radar.

The mission has been granted 5 mission extensions that will carry it to at least 2014.

The mission has been wildly successful except for the piggybacked lander known as Beagle 2, which was British built.

The ambitious British lander was released from the mothership on December 19, 2003, six days before MEX braked into orbit around Mars. Unfortunately the Beagle 2 was never heard from again as it plummeted to the surface and likely crashed.

The high resolution camera (HRSC) has transmitted thousands of dramatic 3D images all over Mars ranging from immense volcanoes, steep-walled canyons, dry river valleys, ancient impact craters of all sizes and shapes and the ever-changing polar ice caps.

It carried the first ever radar sounder (MARSIS) to orbit another planet and has discovered vast caches of subsurface water ice.

MEX also played a significant role as a data relay satellite for transmissions during the landings of NASA’s Phoenix lander and Curiosity rover. It also occasionally relays measurements from Spirit & Opportunity to NASA.

Here is a list of the Top 10 Discoveries from Mars Express from 2003 to 2013:

Mars Express mineralogy maps. This series of five maps shows near-global coverage of key minerals that help plot the history of Mars. The map of hydrated minerals indicates individual sites where a range of minerals that form only in the presence of water were detected. The maps of olivine and pyroxene tell the story of volcanism and the evolution of the planet’s interior. Ferric oxides, a mineral phase of iron, are present everywhere on the planet: within the bulk crust, lava outflows and the dust oxidised by chemical reactions with the martian atmosphere, causing the surface to ‘rust’ slowly over billions of years, giving Mars its distinctive red hue.

#1. First detection of hydrated minerals in the form of phyllosilicates and hydrated sulfates – evidence of long periods of flowing liquid water from the OMEGA visible and infrared spectrometer provided confirmation that Mars was once much wetter than it is today and may have been favorable for life to evolve.

#2. Possible detection of methane in the atmosphere from the Planetary Fourier Spectrometer (PFS) which could originate from biological or geological activity.

#3. Identification of recent glacial landforms via images from the High Resolution Stereo Camera (HRSC) are stem from viscous flow features composed of ice-rich material derived from adjacent highlands.

#4. Probing the polar regions. OMEGA and MARSIS determined that the south pole consists of a mixture frozen water ice and carbon dioxide. If all the polar ice melted the planet would be covered by an ocean 11 meters deep.

#5. Recent and episodic volcanism perhaps as recently as 2 million years ago. Mars has the largest volcanoes in the solar system . They are a major factor in the evolution of the martian surface, atmosphere and climate.

#6. Estimation of the current rate of atmospheric escape, helps researchers explain how Mars changed from a warm, wet place to the cold, dry place it is today.

#7. Discovery of localised aurora on Mars

#8. A new, meteoric layer in the martian ionosphere created by fast-moving cosmic dust which burns up as it hits the atmosphere.

#9. Unambiguous detection of carbon dioxide clouds. The freezing and vaporisation of CO2 is one of the main climatic cycles of Mars, and it controls the seasonal variations in surface air pressure.

#10. Unprecedented probing of the Martian moon Phobos – which could be a target for future landers and human missions.
