A robot from Earth has successfully drilled into a Martian rock for the first time ever and exposed pristine alien material for high powered science analysis.

NASA’s car sized Curiosity rover deliberately plunged the drill bit on the end of her 7 foot (2.1 m) robot arm into a flat outcrop of rocks possessing hydrated mineral veins, that is situated inside a shallow basin named Yellowknife Bay where water repeatedly flowed.

“The drill test was done. The mission has been spectacular so far,” said Dr. Jim Green, Director of NASA Planetary Sciences Division at NASA HQ, in an exclusive interview today with Universe Today on the campus of Princeton University. “The area is tremendously exciting.”

And what’s even more amazing is that as Curiosity hammered straight down into the rock outcrop, it appears that the resulting vibrations also simultaneously uncovered a hidden vein of whitish colored material that might be calcium sulfate – as the Martian ground shook and a thin layer of rust colored soil was visibly dislodged.

The robot is working at a place called Glenelg – where liquid water once flowed eons ago across the Red Planet’s surface.

“This area is really rich with all the cracks in the rocks and the veins. It’s really fabulous,” Green told me. “The landing was an engineering feat that enabled us to do all this great science that comes next.”

Drill, Baby, Drill !! — Drilling is essential toward achieving Curiosity’s goal of determining whether Mars ever offered an environment favorable for microbial life, past or present

The drill bit penetrated a few millimeters deep into the intriguing outcrop called ‘John Klein’ as planned during the drill tests run on Jan 31 and Feb 2, 2013 (or Sols 174 & 176), Green elaborated. The results were confirmed in new images snapped by Curiosity over the past few days, that trickled back to Earth this weekend across millions of miles of interplanetary space.

Several different cameras – including the high resolution MAHLI microscopic imager on the arm tool turret – took before and after up-close images to assess the success of the drilling maneuver.

The Alpha Particle X-Ray Spectrometer (APXS) was also placed in contact with the ground to determine the chemical composition of the rock drill test site and possible calcium sulfate vein and investigate its hydration state.

The drill test marks an historic first time achievement in the annuls of space exploration.

NASA’s Spirit and Opportunity Mars rovers successfully abraded numerous rocks but are not equipped with penetrating drills or sample acquisition and analysis instruments.

During this initial test, Curiosity’s hi-tech drill was used only in the percussion mode – hammering back and forth like a chisel. No tailings were collected for analysis. The 5/8-inch (16 mm) wide bit will be rotated in upcoming exercises to bore several test holes.

Green told me that the Curiosity science and engineering team says that this initial test will soon be following up by more complex tests that will lead directly to drilling into the interior of a rock for the first ever sampling and analysis of fresh, rocky Martian material.

“The drill test results are looking good so far,” Green said. “Depending on the analysis, it’s possible that the initial test bore hole could be drilled as early as tonight. Sampling could follow soon.”

The science and engineering team are wisely being “ultra careful” says Green, in slowly and methodically checking out the highly complex drill.

“We are motivated to work in a stepwise fashion to get it right,” Green elaborated.

“The drilling has got to be done carefully. We are still in checkout mode and the drill is the last instrument of Curiosity’s ten science instruments to be fully checked out.”

Curiosity can drill to a depth of about 2 inches (5 cm) into rocks. Ultimately a powdered and sieved sample about half an aspirin tablet in size will be delivered to the SAM and CheMin analytical labs on the rover deck.

“The drilling is going very well so far and we’re making great progress with the early steps,” said Curiosity project scientist Prof John Grotzinger to the BBC.

Drilling goes to the heart of the mission. The cored rock samples will be analyzed by the duo of chemical spectrometers to ascertain their elemental composition and determine if organic molecules – the building blocks of life – are present.

The 1 ton robot will spend at least several weeks or more investigating Yellowknife Bay and Glenelg – which lies at the junction of three different types of geologic terrain.

Thereafter, the six-wheeled mega rover will set off on a 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 long awaited and history making first use of a drill on Mars is set to happen on Thursday, Jan. 31, 2013, or Sol 174, by NASA’s Curiosity Mars Science Lab (MSL) rover, if all goes well, according to science team member Ken Herkenhoff of the USGS.

Curiosity’s first drilling operation entails hammering a test hole into a flat rock at the location where the rover is currently parked at a scientifically interesting outcrop of rocks with veined minerals called ‘John Klein’. See our mosaics above & below illustrating Curiosity’s current location.

“Drill tailings will not be collected during this test, which will use only the percussion (not rotation) drilling mode,” says Herkenhoff.

Curiosity is an incredibly complex robot that the team is still learning to operate. So the plan could change at a moment’s notice.

The actual delivery of drill tailings to Curiosity’s CheMin and SAM analytical labs is still at least several days or more away and must await a review of results from the test drill hole and further drilling tests.

“We are proceeding with caution in the approach to Curiosity’s first drilling,” said Daniel Limonadi, the lead systems engineer for Curiosity’s surface sampling and science system at NASA’s Jet Propulsion Laboratory (JPL). “This is challenging. It will be the first time any robot has drilled into a rock to collect a sample on Mars.”

On Sol 166, Curiosity drove about 3.5 meters to reach the John Klein outcrop that the team chose as the 1st drilling site. The car sized rover is investigating a shallow depression known as ‘Yellowknife Bay’ – where she has found widespread evidence for repeated episodes of the ancient flow of liquid water near her landing site inside Gale Crater on Mars.

In anticipation of Thursday’s planned drilling operation, the rover just carried out a series of four ‘pre-load’ tests on Monday (Jan. 27), whereby the rover placed the drill bit onto Martian surface targets at the John Klein outcrop and pressed down on the drill with the robotic arm. Engineers then checked the data to see whether the force applied matched predictions.

“The arm was left pressed against one of them overnight, to see how the pressure changed with temperature,’ says Herkenhoff.

Because huge temperature swings occur on Mars every day (over 65 C or 115 F), the team needs to determine whether there is any chance of excessive stress on the arm while it is pressing the drill down onto the Martian surface. The daily temperature variations can cause rover systems like the arm, chassis and mobility system to expand and contact by about a tenth of an inch (about 2.4 millimeters), a little more than the thickness of a U.S. quarter-dollar coin.

“We don’t plan on leaving the drill in a rock overnight once we start drilling, but in case that happens, it is important to know what to expect in terms of stress on the hardware,” said Limonadi. “This test is done at lower pre-load values than we plan to use during drilling, to let us learn about the temperature effects without putting the hardware at risk.”

The high resolution MAHLI microscopic imager on the arm turret will take close-up before and after images of the outcrop target to assess the success of the drilling operation.

On Sol 175, another significant activity is planned whereby one of the ‘blank” organic check samples brought from Earth will be delivered to the SAM instrument for analysis as a way to check for any traces of terrestrial contamination of organic molecules and whether the sample handing system was successfully cleansed earlier in the mission at the Rocknest windblown sand ripple.

Meanwhile on the opposite side of Mars, NASA’s Opportunity rover starts Year 10 investigating never before touched phyllosilicate clay minerals that formed eons ago in flowing liquid water at Endeavour crater – detailed here.

Stay tuned for exciting results from NASA’s Martian sisters.

Curiosity’s Robotic Arm Camera Snaps 1st Night Images

Image caption: This image of a Martian rock illuminated by white-light LEDs (light emitting diodes) is part of the first set of nighttime images taken by the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm of NASA’s Mars rover Curiosity.

Curiosity’s high resolution robotic arm camera has just snapped the 1st set of night time images of a Martian rock of the now 5 1/2 month long mission – using illumination from ultraviolet and white light emitting LED’s. See the images above and below.

The Mars Hand Lens Imager (MAHLI) camera is located on the tool turret at the end of Curiosity’s 7 foot (2.1 m) long robotic arm.

MAHLI took the close-up images of a rock target named “Sayunei” on Jan. 22 (Sol 165), located near the front-left wheel after the rover had driven over and scuffed the area to break up rocks in an effort to try and expose fresh material, free of obscuring dust.

“Sayunei” is at the site of the “John Klein” outcrop in “Yellowknife Bay” where the team hopes to commence the 1st rock drilling operations here in the coming days. Curiosity drove a few meters several sols ago to reach “John Klein”.

See below our Sol 157 mosaic showing the “John Klein” outcrop – where the rover snapped these night images of “Sayunei”.

“The purpose of acquiring observations under ultraviolet illumination was to look for fluorescent minerals,” said MAHLI Principal Investigator Ken Edgett of Malin Space Science Systems, San Diego. “These data just arrived this morning. The science team is still assessing the observations. If something looked green, yellow, orange or red under the ultraviolet illumination, that’d be a more clear-cut indicator of fluorescence.”

Analysis is still in progress to determine whether fluorescent minerals are present. Certain classes of organic compounds are also fluorescent.

MAHLI is an adjustable focus camera that works over a wide range. It can focus on targets just a few centimeters away or on distant objects like Mount Sharp, over 6 miles (10 km) away.

The LED’s surround the MAHLI lens.

Curiosity has discovered widespread evidence for the ancient flow of liquid water at “Yellowknife Bay” in the form of water bearing mineral veins, cross-bedded layering, nodules and spherical sedimentary concretions.

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.

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 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.

Curiosity Touches Mars at Yellowknife Bay and Drives to Snake River for Drilling

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.

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.

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.

Can Humans Live on Mars?

Metallic robots constructed by ingenious humans can survive on Mars. But what about future human astronauts?

NASA’s plucky Mars Exploration Rover Opportunity has thrived for nearly a decade traversing the plains of Meridiani Planum despite the continuous bombardment of sterilizing cosmic and solar radiation from charged particles thanks to her radiation hardened innards.

How about humans? What fate awaits them on a bold and likely year’s long expedition to the endlessly extreme and drastically harsh environment on the surface of the radiation drenched Red Planet – if one ever gets off the ground here on Earth? How much shielding would people need?

Answering these questions is one of the key quests ahead for NASA’s SUV sized Curiosity Mars rover – now 100 Sols, or Martian days, into her 2 year long primary mission phase.

Preliminary data looks promising.

Curiosity survived the 8 month interplanetary journey and the unprecedented sky crane rocket powered descent maneuver to touch down safely inside Gale Crater beside the towering layered foothills of 3 mi. (5.5 km) high Mount Sharp on Aug. 6, 2012.

Now she is tasked with assessing whether Mars and Gale Crater ever offered a habitable environment for microbial life forms – past or present. Characterizing the naturally occurring radiation levels stemming from galactic cosmic rays and the sun will address the habitability question for both microbes and astronauts. Radiation can destroy near-surface organic molecules.

Researchers are using Curiosity’s state-of-the-art Radiation Assessment Detector (RAD) instrument to monitor high-energy radiation on a daily basis and help determine the potential for real life health risks posed to future human explorers on the Martian surface.

“The atmosphere provides a level of shielding, and so charged-particle radiation is less when the atmosphere is thicker,” said RAD Principal Investigator Don Hassler of the Southwest Research Institute in Boulder, Colo. See the data graphs herein.

“Absolutely, the astronauts can live in this environment. It’s not so different from what astronauts might experience on the International Space Station. The real question is if you add up the total contribution to the astronaut’s total dose on a Mars mission can you stay within your career limits as you accumulate those numbers. Over time we will get those numbers,” Hassler explained.

The initial RAD data from the first two months on the surface was revealed at a media briefing for reporters on Thursday, Nov. 15 and shows that radiation is somewhat lower on Mars surface compared to the space environment due to shielding from the thin Martian atmosphere.

This graphic shows the variation of radiation dose measured by the Radiation Assessment Detector on NASA’s Curiosity rover over about 50 sols, or Martian days, on Mars. (On Earth, Sol 10 was Sept. 15 and Sol 60 was Oct. 6, 2012.) The dose rate of charged particles was measured using silicon detectors and is shown in black. The total dose rate (from both charged particles and neutral particles) was measured using a plastic scintillator and is shown in red. Credit: NASA/JPL-Caltech/ SwRI

RAD hasn’t detected any large solar flares yet from the surface. “That will be very important,” said Hassler.

“If there was a massive solar flare that could have an acute effect which could cause vomiting and potentially jeopardize the mission of a spacesuited astronaut.”

“Overall, Mars’ atmosphere reduces the radiation dose compared to what we saw during the cruise to Mars by a factor of about two.”

RAD was operating and already taking radiation measurements during the spacecraft’s interplanetary cruise to compare with the new data points now being collected on the floor of Gale Crater.

Mars atmospheric pressure is a bit less than 1% of Earth’s. It varies somewhat in relation to atmospheric cycles dependent on temperature and the freeze-thaw cycle of the polar ice caps and the resulting daily thermal tides.

“We see a daily variation in the radiation dose measured on the surface which is anti-correlated with the pressure of the atmosphere. Mars atmosphere is acting as a shield for the radiation. As the atmosphere gets thicker that provides more of a shield. Therefore we see a dip in the radiation dose by about 3 to 5%, every day,” said Hassler.

There are also seasonal changes in radiation levels as Mars moves through space.

The RAD team is still refining the radiation data points.

“There’s calibrations and characterizations that we’re finalizing to get those numbers precise. We’re working on that. And we’re hoping to release that at the AGU [American Geophysical Union] meeting in December.”

Image caption: Daily Cycles of Radiation and Pressure at Gale Crater. This graphic shows the daily variations in Martian radiation and atmospheric pressure as measured by NASA’s Curiosity rover. As pressure increases, the total radiation dose decreases. When the atmosphere is thicker, it provides a better barrier with more effective shielding for radiation from outside of Mars. At each of the pressure maximums, the radiation level drops between 3 to 5 percent. The radiation level goes up at the end of the graph due to a longer-term trend that scientists are still studying. Credit: NASA/JPL-Caltech/SwRI

Radiation is a life limiting factor to habitability. RAD is the first science instrument to directly measure radiation from the surface of a planet other than Earth.

“Curiosity is finding that the radiation environment on Mars is sensitive to Mars weather and climate,” Hassler concluded.

Unlike Earth, Mars lost its magnetic field some 3.5 billion years ago – and therefore most of its shielding capability from harsh levels of energetic particle radiation from space.

Much more data will need to be collected by RAD before any final conclusions on living on Mars, and for how long and in which type habitats, can be drawn.
