Curiosity Rover Report: At Grandma’s House

MSL team member Colette Lohr, the Tactical Uplink Lead, provides the latest video update on the Curiosity rover. The rover is at a location fittingly dubbed “Grandma’s House” during the holidays, and there should be many more adventures during 2013.

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.

Curiosity will spend at least another month or more investigating Glenelg before setting off on the nearly year long trek to her main destination – the sedimentary layers of the lower reaches of the 3 mile (5 km) high mountain named Mount Sharp.

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

Mars Curiosity Sisters a1_Ken Kremer

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.

Curiosity Update: Wrapping Up Rocknest

Here’s the latest video update from the MSL science team on Curiosity’s activities. It really just wraps up and recaps our article from earlier this week — that all of Curiosity’s science instruments are now fully up and running, that they found materials on Mars that have been seen by other missions, and they are still looking at some interesting carbon compounds. Also, Ashwin Vasavada reiterates what the science team said on Monday at the press conference: They’re doing science at the speed of science, and no one image or data point will cause us to re-write our science books.

As for what the rover will do next, a couple team members Tweeted today that the rover’s wake up song today was “Should I Stay or Should I Go.” Curiosity is now finishing up at observations at an area called Point Lake; they’ll do some surveys of they another area called Yellowknife Bay, and in the next couple of weeks, do some drive-by imaging, perhaps use ChemCam, and the team said they would really like to find a target for the first use of Curiosity’s drill before the holidays start here on Earth.

NASA Reveals Plans for New Mars Rover

Sequels are all the rage these days… even for NASA, apparently.

At the American Geophysical Union 2012 convention in San Francisco today, NASA’s associate administrator for science John Grunsfeld revealed the agency’s plans for another Mars mission. Slated to land in 2020, it will be a rover based on the same design as Mars Science Laboratory. Estimated cost of the mission was announced to be $1.5 billion.

This news brought mixed reactions from many of those in attendance as well as followers online, as while more exploration of the Red Planet is certainly an exciting concept, we have all heard — and seen — countless tales of budget cuts and funding problems throughout NASA over recent years, and many proposed missions and collaborations have had to be shelved or cut short due to lack of funds (remember ExoMars?) Even though the budget for this mission is supposedly “not being taken from other areas,” it’s clearly not going to them either. It will be interesting to see how this plays out across the agency.

The full press release from NASA can be seen below:

(Via NASA)

Building on the success of Curiosity’s Red Planet landing, NASA has announced plans for a robust multi-year Mars program, including a new robotic science rover set to launch in 2020. This announcement affirms the agency’s commitment to a bold exploration program that meets our nation’s scientific and human exploration objectives.

“The Obama administration is committed to a robust Mars exploration program,” NASA Administrator Charles Bolden said. “With this next mission, we’re ensuring America remains the world leader in the exploration of the Red Planet, while taking another significant step toward sending humans there in the 2030s.”

The planned portfolio includes the Curiosity and Opportunity rovers; two NASA spacecraft and contributions to one European spacecraft currently orbiting Mars; the 2013 launch of the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter to study the Martian upper atmosphere; the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission, which will take the first look into the deep interior of Mars; and participation in ESA’s 2016 and 2018 ExoMars missions, including providing “Electra” telecommunication radios to ESA’s 2016 mission and a critical element of the premier astrobiology instrument on the 2018 ExoMars rover.

The plan to design and build a new Mars robotic science rover with a launch in 2020 comes only months after the agency announced InSight, which will launch in 2016, bringing a total of seven NASA missions operating or being planned to study and explore our Earth-like neighbor.

The 2020 mission will constitute another step toward being responsive to high-priority science goals and the president’s challenge of sending humans to Mars orbit in the 2030s.

The future rover development and design will be based on the Mars Science Laboratory (MSL) architecture that successfully carried the Curiosity rover to the Martian surface this summer. This will ensure mission costs and risks are as low as possible, while still delivering a highly capable rover with a proven landing system. The mission will constitute a vital component of a broad portfolio of Mars exploration missions in development for the coming decade.

The mission will advance the science priorities of the National Research Council’s 2011 Planetary Science Decadal Survey and responds to the findings of the Mars Program Planning Group established earlier this year to assist NASA in restructuring its Mars Exploration Program.

“The challenge to restructure the Mars Exploration Program has turned from the seven minutes of terror for the Curiosity landing to the start of seven years of innovation,” Grunsfeld said. “This mission concept fits within current and projected Mars exploration budget, builds on the exciting discoveries of Curiosity, and takes advantage of a favorable launch opportunity.”

The specific payload and science instruments for the 2020 mission will be openly competed, following the Science Mission Directorate’s established processes for instrument selection. This process will begin with the establishment of a science definition team that will be tasked to outline the scientific objectives for the mission.

This mission fits within the five-year budget plan in the president’s Fiscal Year 2013 budget request, and is contingent on future appropriations.

Plans also will include opportunities for infusing new capabilities developed through investments by NASA’s Space Technology Program, Human Exploration and Operations Mission Directorate, and contributions from international partners.

NASA and John Grunsfeld will be hosting a follow-up press conference later today at AGU, which will be streamed live online at 7 p.m. EST/4 p.m. PST. Stay tuned for more information.

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.

Mars Dust Storm Likely Not Going Global

A regional dust storm visible in the southern hemisphere of Mars in this nearly global mosaic of observations made by the Mars Color Imager on NASA’s Mars Reconnaissance Orbiter on Nov. 25, 2012, has contracted from its size a week earlier. Image credit: NASA/JPL-Caltech/MSSS

Good news for the spacecraft sitting on or orbiting Mars: a dust storm on the Red Planet that looked as though it could spread around the entire planet now appears to be abating rather than going global, NASA says.

“During the past week, the regional storm weakened and contracted significantly,” said Bruce Cantor of Malin Space Science Systems, San Diego. Cantor uses the Mars Color Imager camera on NASA’s Mars Reconnaissance Orbiter to monitor storms on the Red Planet.

Recent images and data from the Environmental Monitoring Station (REMS) on the Curiosity rover have also shown a hazy atmosphere and air pressure changes in the vicinity of Gale Crater.

“We are getting lots of good data about this storm,” said Mark Richardson of Ashima Research, Pasadena, California, a co-investigator both on REMS and on the Mars Reconnaissance Orbiter’s Mars Climate Sounder instrument, which has been detecting widespread effects of the current storm on atmospheric temperatures.

Here’s a look at the growing dust storm from the Mars Color Imager on NASA’s Mars Reconnaissance Orbiter on Nov. 18, 2012 to compare with the lead image:

Researchers anticipate that the unprecedented combination of a near-equatorial weather station at ground level, and daily orbital observations during Mars’ dust-storm season, may provide information about why some dust storms grow larger than others.

This is good information to have for any potential future human visitors to Mars.

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.

Is Historic Discovery imminent concerning Martian Organic Chemistry ?

Has Curiosity made a ‘Historic’ science discovery with the SAM (Sample Analysis at Mars) chemistry instrument that analyzes Martian soil (see mosaic above) and is designed to detect organic molecules – the building blocks of life? Has Curiosity unambiguously and directly detected the first signatures of organics on Mars ? Is an announcement imminent?

Speculation is rampant that NASA’s Curiosity Mars rover has made an earth-shaking discovery ‘for the history books’ , following a radio interview by NPR’s Joe Palca with the mission’s Principal Investigator, John Grotzinger, while sitting in his office at Caltech last week. NPR reported the story on Tuesday, Nov. 20.

“We’ve got a briefing on Monday [Dec 3] where we’ll discuss our results,” John Grotzinger told me.

Grotzinger will describe the SAM data and their potentially pivotal implications at the annual meeting of the AGU (American Geophysical Union) being held from Dec 3-7 in San Francisco. Many papers and results from the first three months of the Curiosity Mars Science Lab (MSL) mission will be presented at the AGU meeting.

“The science team is analyzing data from SAM’s soil inspection, but not ready to discuss yet,” JPL Press spokesman Guy Webster informed me today.

It’s the Thanksgiving holiday period here in the US so the answers will wait a tad longer.

Curiosity had been collecting and analyzing Martian soil samples for more than a month at a windblown ripple called ‘Rocknest’. So far Curiosity has scooped into the Martian soil five times and delivered a single sample to SAM and two to the adjacent CheMin chemistry instrument.

“This data is gonna be one for the history books,” Grotzinger went on to say to NPR. “It’s looking really good.”

JPL Press spokesman Guy Webster advises caution and patience while damping down euphoria. He told me that the team is still trying to interpret and understand the analysis from SAM and seeking to clarify their meaning before making any premature conclusions.

“This is no change from the policy with past results from the mission, such as SAM’s atmosphere analysis or CheMin’s soil sample analysis: The scientists want to gain confidence in the findings before taking them outside of the science team,” Webster informed me.

“As for history books, the whole mission is for the history books. John was delighted about the quality and range of information coming in from SAM during the day a reporter happened to be sitting in John’s office last week. He has been similarly delighted by results at other points during the mission so far,” Webster said.

Organic molecules are the basis for life as we know it, and they have never before been discovered on the Red Planet’s surface. I am an organic chemist and to me the detection of organics on Mars would indeed be “Earth-shaking”. But just a finding of organics alone does NOT mean we discovered life. Organics are a prerequisite to life. Life requires finding much more complex molecules, like amino acids and far more beyond that.

Furthermore, finding signatures of organics so close to the surface might be a surprising result when one recalls that highly destructive ionizing radiation bombards the Martian topsoil 24/7.

So, it’s wise for the MSL team to be abundantly cautious and recheck their results multiple times. They wisely waited for further data before prematurely announcing the discovery of Martian methane. Initial SAM atmospheric measurements detecting methane turned out to be false – they actually originated from contamination by residual traces of Florida air trapped in the interior chambers of SAM and were carried all the way to Mars.

If organics are detected in the dusty dunes at Rocknest, the implications could be vast and potentially point to their widespread distribution across Gale crater and beyond.

As renowned astronomer Carl Sagan once said; ‘Extraordinary claims require extraordinary evidence.”

Stay tuned.
