Watery Science ‘Jackpot’ Discovered by Curiosity

Curiosity found widespread evidence for flowing water in the highly diverse, rocky scenery shown in this photo mosaic from the edge of Yellowknife Bay on Sol 157 (Jan 14, 2013). The rover will soon conduct 1st Martian rock drilling operation at flat, light toned rocks at the outcrop called “John Klein”, at center. ‘John Klein’ drill site and ‘Sheep Bed’ outcrop ledges to right of rover arm are filled with numerous mineral veins and spherical concretions which strongly suggest precipitation of minerals from liquid water. ‘Snake River’ rock formation is the linear chain of rocks protruding up from the Martian sand near rover wheel.

The Curiosity rover hit the science “jackpot” and has discovered widespread further evidence of multiple episodes of liquid water flowing over ancient Mars billions of years ago when the planet was warmer and wetter, scientists announced. The watery evidence comes in the form of water bearing mineral veins, cross-bedded layering, nodules and spherical sedimentary concretions.

Any day now NASA’s mega robot will be instructed to drill directly into veined rocks where water once flowed, the team announced at a media briefing this week.

Delighted researchers said Curiosity surprisingly found lots of evidence for light-toned chains of linear mineral veins inside fractured rocks littering the highly diverse Martian terrain – using her array of ten state-of-the-art science instruments. Veins form when liquid water circulates through fractures and deposit minerals, gradually filling the insides of the fractured rocks over time.

Sometime in the next two weeks or so, NASA’s car sized rover will carry out history’s first ever drilling inside a Martian rock that was “percolated” by liquid water – an essential prerequisite for life as we know. A powdered sample will then be delivered to the robots duo of analytical chemistry labs (CheMin & SAM) to determine its elemental composition and ascertain whether organic molecules are present.

The drill target area is named “John Klein” outcrop, in tribute to a team member who was the deputy project manager for Curiosity at JPL for several years and who passed away in 2011.

“We identified a potential drill target and are preparing to do drill activities in the next two weeks. We are ready to go,” said Richard Cook, the project manager of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif.

“Drilling [into a rock] is the most significant engineering activity since landing. It is the most difficult aspect of the surface mission, interacting with an unknown surface terrain, and has never been done on Mars. We will go slowly. It will take some time to deliver samples to CheMin and SAM and will be a great set of scientific measurements.”

These veins form when water circulates through fractures, depositing minerals along the sides of the fracture, to form a vein. These vein fills are characteristic of the stratigraphically lowest unit in the “Yellowknife Bay” area where Curiosity is currently exploring and were imaged on Sol 126 (Dec. 13, 2012) by the telephoto Mastcam camera.

“The scientists have been let into the candy store,” said Cook referring to the unexpected wealth of science targets surrounding the rover at this moment.

“There is a high diversity of rocks types here to characterize,” added Mike Malin, Mastcam principal investigator of Malin Space Science Systems (MSSS). “We see layering, veins and concretions. The area is still undergoing some changes.”

Curiosity is just a few meters away from ‘John Klein’ and will drive to the site shortly from her location inside ‘Yellowknife Bay’ beside the ‘Snake River’ rock formation. To see where Curiosity is in context with ‘John Klein’ and “Snake River’, see our annotated context mosaic (by Ken Kremer & Marco Di Lorenzo) as the rover collects data at a rock ledge.

The white colored veins were discovered over the past few weeks- using the high resolution mast- mounted imaging cameras and ChemCam laser firing spectrometer -at exactly the vicinity where Curiosity is currently investigating ; around a shallow basin called Yellowknife Bay and roughly a half mile away from the landing site inside Gale Crater.

“This lowest unit that we are at in Yellowknife Bay, the very farthest thing we drove to, turns out to be kind of the ‘jackpot’ unit here,” said John Grotzinger, the mission’s chief scientist of the California Institute of Technology. “It is literally shot through with these fractures and vein fills.”

Image caption: ‘John Klein’ Site Selected for Curiosity’s Drill Debut. This view shows the patch of veined, flat-lying rock selected as the first drilling site. The rover’s right Mast Camera equipped with a telephoto lens, was about 16 feet (5 meters) away from the site when it recorded this mosaic on sol 153 (Jan. 10, 2013). The area is shot full of fractures and veins, with the intervening rock also containing concretions, which are small spherical concentrations of minerals. Enlargement A shows a high concentration of ridge-like veins protruding above the surface. Some of the veins have two walls and an eroded interior. Enlargement B shows that in some portions of this feature, there is a horizontal discontinuity a few centimeters or inches beneath the surface. The discontinuity may be a bed, a fracture, or potentially a horizontal vein. Enlargement C shows a hole developed in the sand that overlies a fracture, implying infiltration of sand down into the fracture system. Image has been white-balanced. Credit: NASA/JPL-Caltech/MSSS

Shortly after landing the team took a calculated gamble and decided to take a several months long detour away from the main destination of the towering, sedimentary mountain named Mount Sharp, and instead drive to an area dubbed ‘Glenelg’ and home to ‘Yellowknife Bay’, because it sits at the junction of a trio of different geologic terrains. Glenelg exhibits high thermal inertia and helps put the entire region in better scientific context. The gamble has clearly payed off.

“We chose to go there because we saw something anomalous, but wouldn’t have predicted any of this from orbit,” said Grotzinger.

The Chemistry and Camera (ChemCam) instrument found elevated levels of calcium, sulfur and hydrogen. Hydrogen is indicative of water.

The mineral veins are probably comprised of calcium sulfate – which exists in several hydrated (water bearing) forms.

“The ChemCam spectra point to a composition very high in calcium. These veins are likely composed of hydrated calcium sulfate, such as bassinite or gypsum, depending on the hydration state,” said ChemCam team member Nicolas Mangold of the Laboratoire de Planétologie et Géodynamique de Nantes in France. “On Earth, forming veins like these requires water circulating in fractures and occur at low to moderate temperatures.”

The newly found veins appear quite similar to analogous veins discovered in late 2011 by NASA’s Opportunity rover – Curiosity’s older sister – inside Endeavour crater and nearly on the opposite side of Mars. See our Opportunity vein mosaic featured at APOD on Dec. 11, 2011 to learn more about veined rocks.

“What these vein fills tell us is water moved and percolated through these rocks, through these fracture networks and then minerals precipitated to form the white material which ChemCam has concluded is very likely a calcium sulfate, probably hydrated in origin,” Grotzinger explained.

“So this is the first time in this mission that we have seen something that is not just an aqueous environment, but one that also results in precipitation of minerals, which is very attractive to us.”

Yellowknife Bay and the ‘John Klein’ drilling area outcrop are chock full of mineral veins and sedimentary concretions.

“When you put all this together it says that basically these rocks were saturated with water. There may be several phases to this history of water, but that’s still to be worked out.”

“This has been really exciting and we can’t wait to start drilling,” Grotzinger emphasized.

Curiosity can drill about 2 inches (5 cm) into rocks. Ultimately a powdered sample about half an aspirin tablet in size will be delivered to SAM and CheMin after a few weeks. All rover systems and instruments are healthy, said Cook.

Grotzinger said that Curiosity will be instructed to drive over the veins to try and break them up and expose fresh surfaces for analysis. Then she will drill directly into a vein and hopefully catch some of the surrounding material as well.

“This will reveal the mineralogy of the vein filling material and how many hydrated mineral phases are present. The main goal is this will give us an assessment of the habitability of this environment.”

As the rover has driven down the shallow depression to deeper stratigraphic layers, the units are older in time.

After the first drill sample is fully analyzed, Grotzinger told me that the team will reevaluate whether to drill into a second rock.

The team doesn’t yet know whether the flowing water from which the veins precipitated was a more neutral pH or more acidic. “It’s too early to tell. We need to drill into the rock to tell and determine the mineralogy,” Grotzinger told me. Neutral water is more hospitable to life.

How long the episodes of water flowed is not yet known and it’s a complex history. But the water was at least hip to ankle deep at times and able to transport and round the gravel.

“There are a broad variety of sedimentary rocks here, transported from elsewhere. Mars was geologically active in this location, which is totally cool !,” said Aileen Yingst, MAHLI deputy principal investigator. ”There are a number of different transport mechanisms in play.”

Drilling goes to the heart of the mission and will mark a historic feat in planetary exploration – as the first time that an indigenous sample has been cored from the interior of a rock on another planet and subsequently analyzed by chemical spectrometers to determine its elemental composition and determine if organic molecules are present .

The high powered hammering drill is located on the tool turret at the end of the car-sized robots 7 foot (2.1 meter) long mechanical arm . It is the last of Curiosity’s ten instruments that remains to be checked out and put into action.

Curiosity landed on the Red Planet five months ago inside Gale Crater to investigate whether Mars ever offered an environment favorable for microbial life, past or present and is now nearly a quarter of the way through her two year prime mission.

Curiosity might reach the base of Mount Sharp by the end of 2013, which is about 6 miles (10 km) away as the Martian crow flies.

Rover Team Chooses 1st Rock Drilling Target for Curiosity

Image caption: Time lapse mosaic shows Curiosity rover’s arm movement from raised position to surface deployment on Sol 149 (Jan. 5) for contact science near the lower point of the slithery chain of narrow protruding rocks known as ‘Snake River’ – located inside the basin called “Yellowknife Bay’.

A team of Mars scientists and engineers have chosen the 1st rock drilling target for NASA’s Curiosity rover after carefully considering a range of options over the past several weeks at the robots current location inside a shallow depression known as ‘Yellowknife Bay’, which is replete with light toned rocks.

An official NASA announcement with further information is forthcoming on Tuesday this week, according to a source for this report.

Curiosity is now conducting a detailed science evaluation of the vicinity around a slithery chain of rocks called ‘Snake River’, jutting up from the sandy, rock strewn Martian floor – see our illustrative photo mosaics above & below and earlier story here.

The first report of the drill target selection came just a day ago from Craig Covault at NASA Watch/Spaceref in an article, here – featuring our ‘Snake River’ time lapse mosaic (by Ken Kremer and Marco Di Lorenzo). The mosaic shows the arm in action deploying its science instruments and rotating to capture pictures with the MAHLI microscopic imager and contact science with the APXS mineral spectrometer.

The exact drilling spot has not been divulged but is likely near ‘Snake River’ and visible in our mosaics from Sol 149 and earlier Sols inside the ‘Yellowknife Bay’ basin – which exhibits cross bedding and is reminiscent of a dried up shoreline. Curiosity has now driven to the larger, broken rock just above, right of the sinuous ‘Snake River’ rock formation for up-close contact science investigations.

The Mars Science Lab (MSL) team is coordinating with top JPL & NASA management to get approval for the drilling location chosen or select another rock.

The high powered hammering drill is located on the tool turret at the end of the car-sized robots 7 foot (2.1 meter) long mechanical arm.

The percussive drill is the last component of Curiosity’s ten state-of-the-art science instruments that remains to be checked out and put into action.

Rock samples collected from the first test bore holes will be pulverized and the powdery mix will initially be used to rinse the interior chambers of the drill mechanisms and cleanse out residual earthly contaminants – and then dumped. The same procedure was carried out at the windblown ‘Rocknest’ ripple with the initial scoops of soil to cleanse the CHIMRA sample processing systems.

So it’s likely to take several weeks and possible a month or more until sieved samples are finally delivered to the CheMin and SAM analytical chemistry labs on the rover deck for analysis of their inorganic and organic chemical composition.

As a prelude on Sol 150 (Jan 6.), the rover successfully brushed off one of the flat rocks around Snake River for the first time by using the motorized, wire-bristle brush on the Dust Removal Tool (DRT), built by Honeybee Robotics of NYC.

The brushing was completed on a rock target called ‘Ekwir_1’ – see our mosaic showing a before and after comparison of rock surface images snapped by the Mastcam-100 high resolution color camera.

Brushing is a key step prior to rock drilling and allows the team to much more easily gain insight into the rocks composition with the science instruments compared to the obscured view of a dust blanketed rock. Spirit & Opportunity also have Honeybee Robotics built brushes that have still endured throughout their years’ long miraculous lifetimes.

The team then commanded the rover to bump a bit closer to “slightly younger rocks in front of the rover,” says MSL team member Ken Herkenhoff.

“The contact science activities in the current location went well, including the first brushing of the surface. In order to characterize the geology and chemistry of the rocks at the edge of Yellowknife Bay, we intend to repeat the set of brushing, APXS, MAHLI, ChemCam and Mastcam activities at the new location starting on Sol 152.”

“We are studying chemical and textural differences in the rocks near Snake River,” says Herkenhoff.

On Sol 152 (Jan. 8), Curiosity drove 2.5 meters closer to the area surrounding ‘Snake River’ and began snapping high resolution color imagery.

“It’s one piece of the puzzle,” says John Grotzinger, the mission’s chief scientist of the California Institute of Technology. “It has a crosscutting relationship to the surrounding rock and appears to have formed after the deposition of the layer that it transects.”

Grotzinger and the team are excited because Curiosity is a sort of time machine providing a glimpse into the Red Planets ancient history when the environment was warmer and wetter billions of years ago and much more conducive to the origin of life.

Following the Christmas season break for panoramic imaging of her surroundings, NASA’s Curiosity robot has resumed roving around the shallow depression she reached before the holidays called ‘Yellowknife Bay’ and just arrived at a slithery rock called ‘Snake River’.

The top priority is to locate a target rock to drill into – and that momentous event could at last take place in the next week or so. The drill is the last of Curiosity’s suite of ten science instruments to be fully checked out and commissioned for use.

The drilling scene will look a lot like our photo mosaics, above and below, showing the robotic arm deployed for action. The drill is located on the tool turret at the end of the 7 foot (2.1 meter) long mechanical marvel.

The Curiosity research team is using the newly collected cache of high resolution color images to scan her surroundings in search of scientifically interesting rocks for the historic inaugural use of the high powered hammering drill.

The percussive drill will collect the first ever powdered samples from the interior of Martian rocks for analysis by a pair of state-of-the-art analytical chemistry instruments located inside the rover named SAM and CheMin.

“We are firing on all cylinders now and our last thing to do is drilling, and we really hope to start on that process beginning next week,” said John Grotzinger, the mission’s chief scientist of the California Institute of Technology, in an interview with Jonathan Amos of the BBC.

The rover is also using the APXS X-ray mineral spectrometer, ChemCam rock blasting laser and MAHLI hand lens imager to gather science characterization data helpful in choosing the drill target.

Today (Jan. 5) marks exactly 5 months since Curiosity’s hair-raisingly successfully touchdown on Aug. 5, 2012 on the gravelly plains of Gale Crater beside the towering foothills of Mount Sharp, a 3 mi (5 km) high layered mountain holding deposits of hydrated minerals. Mount Sharp is the main destination of Curiosity’s mission.

On Jan. 3 (Sol 147), Curiosity drove another 10 feet (3 meters) northwestward and pulled up to a sinuous rock feature called “Snake River” as part of a campaign to survey a variety of rocks from which to select the drilling site.

“It’s one piece of the puzzle,” says John Grotzinger. “It has a crosscutting relationship to the surrounding rock and appears to have formed after the deposition of the layer that it transects.”

Snake River is a thin curving line of darker rock cutting through flatter rocks and jutting above sand, says NASA. It’s located at the right side edge of our Sol 132 photo mosaic stitched together from raw images by the image processing team of Ken Kremer & Marco Di Lorenzo to provide a context view of the scenery – and were also featured at NBC News by Alan Boyle, BBC News, NASA Watch and the NY Daily News.

So far the robot has driven a total of 2,303 feet (702 meters) and snapped nearly 36,000 pictures.

Yellowknife Bay is a basin inside an area dubbed ‘Glenelg’ that features a flatter and lighter-toned type of terrain from what the mission crossed during its first four months inside Gale Crater. The rover descended about 2 feet (0.5 m) down a slight incline to reach the inside of the depression in December 2012.

“We’re down at the very lowest layer – what would be the oldest layer that we would see in this succession that might be five to eight meters thick, and that is very likely where we are going to choose our first drilling target, because suddenly we’ve come into an area that represents a very high diversity of things we haven’t seen before,” said Grotzinger to the BBC.

“The place where Curiosity is right now is a small stack of layers – very impressive – and they could be 3-3.5 billion years old, and so we’re very excited about this because unlike the soil which we were analyzing before the holiday season – a loose, windswept patch of dirt on the surface of Mars – we’re now going to start digging down into the very ancient bedrock which we really built the rover to look at,” explained Grotzinger.

The mission goal is to search for habitats and determine if Mars ever could have supported microbial life in the past or present during the 2 year primary mission phase.

“We use these layers as a sort of recording device of past events and conditions, and the rover has the same kind of analytical capability that we would use here on Earth to tell us about the early environmental conditions; and, if life had ever evolved, [whether it would] be the kind of environment that would have been conducive towards sustaining that life,” Grotzinger elaborated to the BBC.

Stay tuned.

Today (Dec. 25) Curiosity celebrates her 1st Christmas on Mars at a spot called ‘Yellowknife Bay’. It’s Sol 138 and nearly 5 months since the pulse pounding landing on Aug. 6, 2012 inside Gale Crater. The robot is in excellent health.

Meanwhile her older sister Opportunity will soon celebrate an unfathomable 9 Earth years on Mars in a few short weeks on Jan. 24, 2013 – on the other side of the planet.

NASA’s Curiosity rover reached the shallow depression named ‘Yellowknife Bay’ on Sol 130 (Dec. 17, 2012) after descending about 2 feet (0.5 m) down a gentle slope inside a geologic feature dubbed ‘Glenelg’. See our panoramic mosaics from Yellowknife Bay – above and below for a context view.

The science team is searching for an interesting rock for the inaugural use of the high powered hammering drill.

According to a new report in SpaceRef, the drilling has been delayed due to concerns that frictional heating may potentially cause liquification of the rock to a gooey “Martian Honey” that could potentially clog and seriously damage the sample handling sieves and mechanisms. So the team is carefully re-evaluating the type of rock target and the drilling operation procedures before committing to the initial usage of the percussive drill located on the turret at the terminus of the robotic arm.

The team chose to drive to ‘Yellowknife Bay’ because it features a different type of geologic terrain compared to what Curiosity has driven on previously. The ‘Glenelg’ area lies at the junction of three different types of geologic terrain and is Curiosity’s first extended science destination.

Curiosity arrived at the lip of Yellowknife Bay on Sol 124 and entered the basin on Sol 125 (Dec. 12) and snapped a scouting panoramic view peering into the inviting locale. The rover is also using the APXS X-ray mineral spectrometer, ChemCam laser and MAHLI hand lens imager to gather initial science characterization data.

So far the rover has traversed a total driving distance of some 0.43 mile (700 meters).

Most of the science and engineering team is getting a much needed break to spend time with their families after uploading 11 Sols worth of activities ahead of time to keep the robot humming during the Christmas holiday season. A skeleton crew at JPL is keeping watch to deal with any contingencies.

One of the top priorities is acquiring a high resolution 360 degree Mastcam color panorama. This will be invaluable for selection of the very 1st rock target to drill into and acquire a sample from the interior – a feat never before attempted on Mars.

“We decided to drive to a place with a good view of the outcrops surrounding Yellowknife Bay to allow good imaging of these outcrops before the holiday break,” says rover science team member Ken Herkenhoff. “As the images are returned during the break, we can use them to help decide where to perform the first drilling operation.”

The team expects to choose a drill target sometime in January 2013 after a careful selection process.

The 7 foot (2 m) long robotic arm will deliver that initial, pulverized rock sample to inlet ports on the rover deck for analysis by the high powered duo of miniaturized chemistry labs named Chemin & SAM.

As the Martian crow flies, the breathtaking environs of Mount Sharp are some 6 miles (10 km) away.

The mission goal is to search for habitats and determine if Mars ever could have supported microbial life in the past or present during the 2 year primary mission phase.

NASA’s Curiosity rover is on the final steps of her descent into a geologist’s paradise at an area called ‘Yellowknife Bay’.

Along the way just days ago on Sol 120 (Dec 7, 2012) she stopped to inspect a huge outcrop of layered rocks dubbed ‘Shaler’ and snapped dozens of high resolution photos with the Navcam and Mastcam cameras.

To catch a human’s eye view of the breathtaking terrain of what some might hearken to an ‘unexpected journey’, check out our Sol 120 photo mosaic in 2-D (above) and then compare that with NASA’s 3-D photo mosaic (below). You will need to whip out you red-cyan anaglyph glasses to take in the full measure of Curiosity’s glorious surroundings and the foreboding shadow – can you guess what that is?

The ‘Shaler’ outcrop features a plethora of striking layers, angled to each other in a pattern geologists refer to as ‘crossbedding’.

The team also used Curiosity’s Chemistry and Camera (ChemCam) instrument on the rover’s mast to help assess the content of ‘Shaler.’

With the Christmas holidays fast approaching, the rover science team is searching for a suitable location at Yellowknife Bay to select as the first potential target to drill into with Curiosity’s advanced percussion drill.

Thereafter she will deliver powdered rock samples to the CheMin and SAM duo of miniaturized analytical chemistry labs on the rovers deck to elucidate the inorganic mineral composition as well as seek to determine if any organic molecules are present.

Yellowknife Bay lies within the place dubbed ‘Glenelg’, the rovers first major science destination. Glenelg uniquely sits at the junction of three different types of intersecting geologic features that will help unravel the mysteries of Curiosity’s Gale Crater touchdown zone beside a humongous mountain known as Mount Sharp – the main target of the mission.

After safely surviving the harrowing touchdown at ‘Bradbury Landing’ on Aug. 6, the SUV-sized Curiosity rover has been on a roll to reach the inviting interior terrain of ‘Glenelg’ before Christmas.

The six wheeled robot has thus far traversed more than 0.37 mile (598 meters) and is now driving on top of the most challenging and scientifically rewarding terrain of the entire four month journey.

“The rover is traversing across terrain different from where it has driven earlier, and responding differently,” said Rick Welch, mission manager at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We’re making progress, though we’re still in the learning phase with this rover, going a little slower on this terrain than we might wish we could.”

Curiosity will spend at least several weeks thoroughly investigating Yellowknife Bay before reversing course and setting out on the year-long 6 mile (10 km) trek to the lower reaches of Mount Sharp. Along the way, the science team may possibly choose to re-investigate the Shaler and Hottah outcrops with the rover’s suite of 10 state-of-the-art science instruments.

Curiosity Gets a Sister – What Should She Do ? Scientists Speak

Image caption: Seeing Double – Future Martian Sisters.

Curiosity will apparently get a sister after all and she’ll be born in 2020 – rising from the ashes of a near death experience.

The good news concerning approval of a future NASA Mars rover was announced this week by John Grunsfeld, NASA Associate Administrator for the Science Mission Directorate at NASA HQ, at the 2012 annual meeting of the AGU (American Geophysical Union) held in San Francisco.

What should Curiosity’s younger sister do? There are a multitude of great ideas, but a paucity of money in these very tough budget times – foremost among them is to gather and return the first ever Martian soil samples to Earth. What should the science goals be especially with regards to sample cache/return?

So, I asked these questions to Grunsfeld and leading Mars scientists, including Steve Squyres, Ray Arvidson and Jim Bell, the science team and camera leaders of NASA’s wildly successful Spirit and Opportunity Mars Exploration Rovers (MER). Opportunity is nearing the 9th anniversary of her Red Planet touchdown – and is exploring the most scientifically bountiful terrain yet of her entire mission at this very moment.

The design for the new Mars rover, let’s call it MSL 2, will be largely based on NASA’s hugely successful Curiosity Mars Science Laboratory (MSL) rover and the breathtaking rocket powered ‘Sky Crane’ landing architecture she so elegantly employed for touchdown barely 4 months ago on Aug. 6, 2012.

Grunsfeld and the researchers weighed in to Universe Today with their thoughts on this – “Will the 2020 Mars rover be focused on astrobiology and the search for life? Or, other goals like sample return or future human visits?”

“That question will ultimately be determined by the Science Definition Team,” Grunsfeld told me. “Historically the driving question behind our Mars exploration has been ‘are we alone in the universe?’ that includes searching for signs of conditions supportive of past and/or present life on Mars.”

Steve Squyres, of Cornell University in New York, says that “sample return is the next logical step” in Mars exploration.

“Simple… it should collect and cache a well-chosen set of samples for eventual return to Earth,” Squyres told me. “Doing so was the clear top priority of the recent planetary decadal survey.”

Squyres led the planetary decadel survey for the National Research Council (NRC) and is the scientific Principal Investigator for the Spirit and Opportunity MER rovers.

“The recently announced 2020 rover has the potential to be directly responsive to the recommendations of the recent planetary decadal survey. The highest priority large mission identified by the Mars community, and indeed by the broader planetary community, in the decadal was a rover that would collect and cache a suite of samples for eventual return to Earth. The 2020 rover, which will be based on the highly capable MSL design, clearly can have that capability if it is appropriately equipped,” Squyres elaborated.

“The National Research Council planetary decadal survey documented the US planetary science community’s consensus views on future priorities for planetary exploration. The 2020 rover mission will be consistent with those priorities only if it collects and caches a suite of samples for eventual return to Earth,” Squyres told Universe Today.

Although retrieving and returning pristine samples from the Red Planet’s surface has long been the top priority for many researchers like Squyres, that ambitious goal would also be expensive and likely require a sequential series of flights to accomplish. But it is doable and would enable scientists on Earth to utilize every one of the most powerful science instruments at their disposal to help solve the most fundamental mysteries of all, like; ‘How did the Solar System form’, ’Did life ever exist on Mars’ and “Are We Alone?’

Ray Arvidson, of Washington University in St. Louis and deputy Principal Investigator for the MER rover, said this to Universe Today:

“For the 2020 rover I would frame the rationale and purpose as:

“*The surface area of Mars is equivalent to the surface area of Earth’s continents. The more we look the richer the geologic record relevant to ancient climatic conditions (e.g., the rover bed gravels found by MSL and the new clay hunting grounds Opportunity is exploring). Thus another MSL class rover and payload to a new site of paleo-environmental interest would be wonderful. Imagine trying to unravel Earth’s history by exploring three locations (MER+MSL) on the continents,” Arvidson informed me.

“*Given the rich, complex nature of the geologic record another MSL class rover exploring a new location will definitely help us narrow down the best place to go for sample return.”

“*For the 2020 rover include some engineering tests that will lead to a lower risk sample return mission. This could be what measurements to do to decide on which samples to acquire and keep, could be how to drill, handle, and cache, etc.”

Jim Bell, of Arizona State University and team leader for the MER Pancam cameras also feels that sample return is the top priority.

“I think it’s important that the 2020 rover adhere to the planetary science community’s stated goals for the next flagship-class mission to Mars–that it make significant progress towards a robotic Mars sample return’” Bell told me. “This was the judgment of the recent National Academy of Science’s Planetary Decadal Survey–representing the consensus of more than 1600 professional planetary scientists worldwide. The simplest way to implement that would be to make the 2020 rover a caching rover–able to store well-selected samples for potential later return to Earth by another mission.”

“I’m really excited about the opportunity to send a new MSL-class rover to Mars, and speaking with my Planetary Society President hat on, I think the public will be really excited to follow another mission as well.”

“Mars exploration is incredibly popular, and represents the best aspects of American engineering, innovation, and scientific exploration. That mission, and the continuing discoveries from Curiosity, Opportunity, and other missions, will help get us closer to answering age-old questions like, “are we alone?” Exciting!” Bell said.

By reutilizing the now proven MSL designs, NASA should be able to restrain and accurately estimate the development costs while simultaneously retiring a lot of the unknown risks associated with the construction and testing of MSL 1.

At the AGU briefing, Grunsfeld said that the 2020 rover will cost about $1.5 Billion, plus or minus $200 million, and fits within the president’s NASA budget request for 2013 and going forward. Curiosity cost about $2.5 Billion over the course of a 10 year development span.

“This mission concept fits within the current and projected Mars exploration budget, builds on the exciting discoveries of Curiosity, and takes advantage of a favorable launch opportunity,” says Grunsfeld.

The exact nature and actual mass of the 2020 rover’s science instruments will be decided by the Science Definition Team and also depends on the actual budget allocation received by NASA.

The surprising decision to fund MSL 2 comes despite the Obama Administrations cancellation earlier this year of NASA’s participation in a pair of missions to Mars, jointly proposed with the European Space Agency (ESA) – the 2016 Trace Gas Orbiter and the 2018 ExoMars rover. ESA has now forged a new alliance with Russia to carry out Mars exploration. NASA will fund instruments on both spacecraft.

In February 2012, the Obama Administration cut the planetary science budget by 20% and NASA was forced to withdrawn from the two joint Mars missions with ESA – as outlined earlier here and here.

So, I asked Grunsfeld, “Will the 2020 mission be international with participation by ESA or Roscosmos?”

“Yes, it will be international. Details will be worked out in the planning phase,” Grunsfeld replied.

The 2020 launch window is next most favorable window after 2018 and would permit a higher weight of landed science instruments compared to Curiosity.

U.S. Rep. Adam Schiff (D-CA), who represents the area that is home to NASA’s Jet Propulsion Laboratory, and has worked to reverse the budget cuts, applauded the announcement of “the new robotic science rover set to launch in 2020.”

Schiff issued a statement that said, “While a 2020 launch would be favorable due to the alignment of Earth and Mars, a launch in 2018 would be even more advantageous as it would allow for an even greater payload to be launched to Mars. I will be working with NASA, the White House and my colleagues in Congress to see whether advancing the launch date is possible and what it would entail.”

Now it’s up to NASA to formulate a well defined and realistic plan that the politicians will support. The specific payload and science instruments for the 2020 mission will be openly competed following established processes for instrument selection. A science definition team will be appointed to outline the scientific objectives for the mission.

Stay tuned here for continuing updates on Curiosity and the future of Mars exploration and more.

Read TIME’s statement about voting for Curiosity:

You may own a cool car — you may even own a truly great car — but it’s a cinch that no matter how fantastic it is, it can never be anything more than the second best car in the solar system. The greatest of all is the Mars Curiosity rover, one ton of SUV-size machine now 160 million miles from Earth and trundling across the Martian surface. It was the rover’s landing on Mars last August that first caught people’s eyes: an improbable operation that required a hovering mother ship to lower the rover to the surface on cables like a $2.5 billion marionette. But it’s the two years of exploration Curiosity has ahead of it — with a suite of instruments 10 times as large as any ever carried to Mars before — that will make real news. NASA built the country one sweet ride, and yes, alas, it’s sweeter than yours.

In the days leading up to Thanksgiving, NASA’s Curiosity mega Mars rover completed her first so-called “touch and go” maneuver – whereby she drives to and inspects an interesting rock and then moves on the same day to the next target of interest.

Check out the totally cool action animation below depicting Curiosity’s first ever “touch and go” movement and a subsequent martian drive of 83 feet (25.3 meters) conducted on Nov. 18.

“The ‘touch and go’ on Sol 102 went well, the data arriving in time for planning Sol 104”, says rover team member Ken Herkenhoff, of the US Geological Survey (USGS).

The science and engineering team guiding Curiosity is commanding her to accomplish ever more sophisticated and bold forays across the floor of Gale crater after finishing more than a month of investigations at the windblown ripple named “Rocknest.

On Nov 16, Curiosity drove 6.2 feet (1.9 meters) to get within arm’s reach of a rock called “Rocknest 3”. She deployed the arm and placed the Alpha Particle X-Ray Spectrometer (APXS) instrument onto the rock, and then took two 10-minute APXS readings of data to ascertain the chemical elements in the rock.

Thereafter Curiosity stowed her 7 foot (2.1 m) long arm and drove eastward toward the next target called “Point Lake”.

Curiosity is now inside the ‘Glenelg’ geologic formation which the science team selected as the first major science destination because it lies at the intersection of three diverse types of geology areas that will help unlock the secrets of Mars’ ancient watery history and evolution to modern times.

“We have done touches before, and we’ve done goes before, but this is our first ‘touch-and-go’ on the same day,” said Curiosity Mission Manager Michael Watkins of NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “It is a good sign that the rover team is getting comfortable with more complex operational planning, which will serve us well in the weeks ahead.”

During the holiday period, Curiosity is taking high resolution imagery, conducting atmospheric observations and making measurements with the DAN neutron spectrometer and her other state-of-the-art science instruments.

Meanwhile, the Curiosity science team is still ‘chewing over’ the meaning of the results from the first ever scoopful of soil spooned up at ‘Rocknest’ and ingested by the SAM (Sample Analysis at Mars) chemistry instrument on the rover deck that is designed to detect organic molecules – the building blocks of life.

“We’ve got a briefing on Monday [Dec 3] where we’ll discuss our results,” Curiosity project manager John Grotzinger, of Caltech, told me. Those SAM results will be announced to a flurry of interest during the annual meeting of the AGU (American Geophysical Union) being held from Dec 3-7 in San Francisco.
