NASA’s Curiosity rover successfully blasted a Mars rock with a powerful laser beam, for the first time in history, today Aug. 19, inaugurating a revolutionary new era in planetary science with a new type of instrument that will deliver bountiful discoveries. The fist sized Martian rock zapped during the maiden laser target practice shots was appropriately dubbed “Coronation”.

The ChemCam instrument mounted at the top of Curiosity’s mast fired a total of 30 one-million watt pulses over a 10 second period at the 3 inch wide rock that vaporized a pinhead sized spot into an ionized, glowing plasma.

Each pulse lasted about five one-billionths of a second and was sufficient in energy to generate a spark of plasma to be observed with the ChemCam telescope and trio of spectrometers below deck in order to identify the elemental composition.

“Yes, I’ve got a laser beam attached to my head. I’m not ill tempered; I zapped a rock for science. PewPew,” tweeted Curiosity.

The NASA composite image above shows Coronation before and after the laser shots – watch out little Martians !

“We got a great spectrum of Coronation — lots of signal,” said ChemCam Principal Investigator Roger Wiens of Los Alamos National Laboratory, N.M. “Our team is both thrilled and working hard, looking at the results. After eight years building the instrument, it’s payoff time!”

ChemCam recorded spectra from the laser-induced spark during all 30 pulses at 6,144 different wavelengths of ultraviolet, visible and infrared light. The purpose of this test was target practice to make sure the laser could be precisely aimed and to characterize the instrument.

Ultimately the goal is use the laser to penetrate below the dusty surface and reveal the interior composition of the targeted rocks using the telescopic camera and spectrometers.

ChemCam, which stands for Chemistry and Camera, is a joint project between the US and France said Wiens at a news briefing on Aug. 17. “The science team is half French and half US.”

“It’s surprising that the data are even better than we ever had during tests on Earth, in signal-to-noise ratio,” said ChemCam Deputy Project Scientist Sylvestre Maurice of the Institut de Recherche en Astrophysique et Planetologie (IRAP) in Toulouse, France. “It’s so rich, we can expect great science from investigating what might be thousands of targets with ChemCam in the next two years.”

ChemCam is a remote sensing instrument and will get the most use of any of Curiosity’s instruments. It will be analyzing about 14,000 samples and help winnow down the targets and guide Curiosity to the most interesting samples for more detailed analysis, Wiens explained.

ChemCam uses a technique called laser-induced breakdown spectroscopy that has precedent in determining the composition of targets in other extreme environments such as inside nuclear reactors and on the sea floor, but is unprecedented in interplanetary exploration.

NASA’s 1 ton mega rover Curiosity is the biggest and most complex robot ever sent to the surface of another planet, sporting a payload of 10 state of the art science instruments weighing 15 times more than any prior roving vehicle. Curiosity’s goal is to determine if Mars was ever capable of supporting microbial life, past or present and to search for the signs of life in the form of organic molecules during the 2 year primary mission phase.

1st Laser Firing and 1st Motion Imminent for Curiosity

The 1st firing of Curiosity’s rock zapping laser and 1st motion of her six wheels is imminent and likely to take place within the next 24 to 72 hours said mission scientists at Friday’s (Aug 17) media briefing at NASA’s Jet Propulsion Lab (JPL) in Pasadena, Calif., home to mission control for the nuclear-powered, car-sized robot.

Furthermore the team has decided on the target of her 1st Martian Trek, a science hot spot dubbed Glenelg because it lies at the natural intersection of three different types of geologic formations (see graphic below), including layered bedrock and an alluvial fan through which liquid water flowed eons ago. Glenelg is about 400 meters (1300 feet) east of the rover’s landing site.

With each passing Sol, or Martian day, NASA biggest, best and most daring mobile lab becomes ever more capable, like a growing child, as engineers energize and successfully test more and more of her highly advanced systems to accomplish feats of exploration and discovery never before possible.

“Everything is going really well,” said John Grotzinger, project scientist for NASA’s Curiosity Mars Science Lab (MSL) rover. “The excitement from the point of view of the science team is all the instruments continue to check out.”

Image Caption: Martian Treasure Map -This image shows the landing site of NASA’s Curiosity rover and destinations scientists want to investigate. Curiosity landed inside Gale Crater on Mars on Aug. 5 PDT (Aug. 6 EDT) at the green dot, within the Yellowknife quadrangle. The team has chosen for it to move toward the region marked by a blue dot that is nicknamed Glenelg. That area marks the intersection of three kinds of terrain. The science team thought the name Glenelg was appropriate because, if Curiosity traveled there, it would visit it twice — both coming and going — and the word Glenelg is a palindrome. Then, the rover will aim to drive to the blue spot marked “Base of Mt. Sharp”, which is a natural break in the dunes that will allow Curiosity to begin scaling the lower reaches of Mount Sharp. At the base of Mt. Sharp are layered buttes and mesas that scientists hope will reveal the area’s geological history.

Curiosity will blast her first rock, dubbed N165, in the history of planetary science as early as Saturday night, Aug. 18, with the powerful mast-mounted laser and telescope on the Chemistry and Camera instrument, or ChemCam that includes spectrometers inside the rover.

ChemCam is a remote sensing instrument. It will get the most use by analyzing about 14,000 samples and help winnow down the targets and guide Curiosity to the most interesting samples for detailed analysis, Wiens explained.

“Rock N165 looks like your typical Mars rock, about three inches wide. It’s about 10 feet away,” said Roger Wiens, principal investigator of the ChemCam instrument from the Los Alamos National Laboratory in New Mexico. “We are going to hit it with 14 millijoules of energy 30 times in 10 seconds. It is not only going to be an excellent test of our system, it should be pretty cool too.”

ChemCam has a range of about 23 feet (7 meters). It fires with a million watts of power for 5 billionths of a second, sufficient energy to excite a pinhead sized spot to a glowing plasma that the instrument observes with the spectrometer below deck to identify the chemical composition.

“We are very excited. Our team has waited eight long years to get to this date and we’re happy that everything is looking good so far,” said Wiens. “Hopefully we’ll be back early next week and be able to talk about how Curiosity’s first laser shots went.”

We will take images of Rock N165 before and after the laser firing. The camera has the same resolution as the Mastcam and can take images that resolve to the width of a human hair from 7 feet away.

Engineers plan to turn the rover’s wheels over the next few days and execute a short test drive and turns of about 10 feet (3 meters).

Grotzinger indicated the drive to Glenelg could take a month or more.

“We will drive efficiently to Glenelg and it will take about 3 to 4 weeks. Along the way we may do scooping to take some soil samples if we find fine grained materials”

Glenelg, a palindrome, is also the 1st location where Curiosity will actually drill into rocks. Then it will deliver sifted samples into the two analytical chemistry instruments, SAM (Sample Analysis at Mars) and CheMin (Chemistry and Minerology), which will determine the chemical and mineralogical composition and search for signs of organic molecules – the carbon based molecules that are the building blocks of life.

“We’ll stay and do about a month or more of science at Glenelg”

“With such a great landing spot in Gale Crater, we literally had every degree of the compass to choose from for our first drive,” Grotzinger said. “We had a bunch of strong contenders. It is the kind of dilemma planetary scientists dream of, but you can only go one place for the first drilling for a rock sample on Mars. That first drilling will be a huge moment in the history of Mars exploration.”

After thoroughly investigating Glenelg until around the end of this calendar year, then it’s off to Mount Sharp, an 18,000 foot tall mound (5.5 km) that’s the missions ultimate destination because it preserves millions to billions of years of Martian history, stretching from the wet water era of billions of years ago to the more recent desiccated era. It could take a year or so to reach the base.
Mount Sharp is about 7 kilometers (4.4 miles) distant from the current location of Curiosity.

“What’s really cool about this topography is that the crater rim kind of looks like the Mojave Desert and now what you see here kind of looks like the Four Corners area of the western U.S., or maybe around Sedona, Ariz., where you’ve got these buttes and mesas made out of these layered, kind of light-toned reddish-colored outcrops. There’s just a rich diversity over there,” Grotzinger said at the briefing.

Curiosity will spend years climbing Mount Sharp in search of sedimentary layers of clays and sulfates, the hydrated minerals that form in flowing liquid water and could hold the ingredients of life.

New high resolution images of the foothills of Mount Sharp from Curiosity show the giant mountain’s base is littered with mesas and buttes ranging in height from 1 to 3 story tall buildings, with valleys in between.

Curiosity’s goal is to search for signs of Martian microbial habitats, past or present, with the most sophisticated suite of 10 state of the art science instruments ever sent to the surface of another planet.

Curiosity Wheels Initial Rove in a Week on Heels of Science and Surgery Success

Curiosity’s weekend “Brain transplant” proceeded perfectly and she’ll be ready to drive across the floor of Gale Crater in about a week, said the projects mission managers at a NASA news briefing on Tuesday, Aug. 14. And the team can’t wait to get Curiosity’s 6 wheels mobile on the heels of a plethora of science successes after just a week on Mars.

Over the past 4 sols, or Martian days, engineers at NASA’s Jet Propulsion Lab (JPL) successfully uploaded the new “R10” flight software that is required to carry out science operations on the Red Planet’s surface and transform the car-sized Curiosity from a landing vehicle into a fully fledged rover.

The step by step flight software transition onto both the primary and backup computers “went off without a hitch”, said mission manager Mike Watkins of JPL at the news briefing. “We are ‘Go’ to continue our checkout activities on Sol 9 (today).”
Watkins added that the electronic checkouts of all the additional science instruments tested so far, including the APXS, DAN and Chemin, has gone well. Actual use tests are still upcoming.

“With the new flight software, we’re now going to test the steering actuators on Sol 13, and then we are going to take it out for a test drive here probably around Sol 15,” said Watkins . “We’re going to do a short drive of a couple of meters and then maybe turn and back up.”

See our rover wheel mosaic above, backdropped by the rim of Gale Crater some 15 miles away.

Curiosity made an unprecedented pinpoint landing inside Gale Crater using the rocket powered “Sky Crane” descent stage just a week ago on Aug. 5/6 and the team is now eager to get the huge rover rolling across the Martian plains towards the foothills of Mount Sharp, about 6 miles (10 km) away as the Martian crow flies.

“We have a fully healthy rover and payload,” said Ashwin Vasavada, Mars Science Laboratory (MSL) deputy project scientist. “We couldn’t be happier with the success of the mission so far. We’ve never had a vista like this on another planet before.”

“In just a week we’ve done a lot. We’ve taken our 1st stunning panorama of Gale crater with focusable cameras, 1st ever high energy radiation measurement from the surface, the 1st ever movie of a spacecraft landing on another planet and the 1st ground images of an ancient Martian river channel.”

A high priority is to snap high resolution images of all of Mount Sharp, beyond just the base of the 3.4 mile (5.5 km) tall mountain photographed so far and to decide on the best traverse route to get there.

“We will target Mount Sharp directly with the mastcam cameras in the next few days,” said Watkins.

Climbing the layered mountain and exploring the embedded water related clays and sulfate minerals is the ultimate goal of Curiosity’s mission. Scientists are searching for evidence of habitats that could have supported microbial life.

Curiosity will search for the signs of life in the form of organic molecules by scooping up soil and rock samples and sifting them into analytical chemistry labs on the mobile rovers’ deck.

Vasavada said the team is exhaustively discussing which terrain to visit and analyze along the way that will deliver key science results. He expects it will take about a year or so before Curiosity arrives at the base of Mount Sharp and begins the ascent in between the breathtaking mesas and buttes lining the path upwards to the sedimentary materials.

Watkins and Vasavada told me they are confident they will find a safe path though the dunes and multistory tall buttes and mesas that line the approach to and base of Mount Sharp.

“Curiosity can traverse slopes of 20 degrees and drive over 1 meter sized rocks. The team has already mapped out 6 potential paths uphill from orbital imagery.”

“The science team and our rover drivers and really everybody are kind of itching to move at this point,” said Vasavada. “The science and operations teams are working together to evaluate a few different routes that will take us eventually to Mount Sharp, maybe with a few waypoints in between to look at some of this diversity that we see in these images. We’ll take 2 or 3 samples along the way. That’s a few weeks work each time.”

This processing, called “white balancing,” is useful for scientists to be able to recognize and distinguish rocks by color in more familiar lighting. Credit: NASA/JPL-Caltech/MSSS

“We estimate we can drive something like a football field a day once we get going and test out all our driving capabilities. And if we’re talking about a hundred football fields away, in terms of 10 kilometers or so, to those lower slopes of Mount Sharp, that already is a hundred days plus.”

“It’s going to take a good part of a year to finally make it to these sediments on Mount Sharp and do science along the way,” Vasavada estimated.

The 1 ton mega rover Curiosity is the biggest and most complex robot ever dispatched to the surface of another planet and is outfitted with a payload of 10 state of the art science instruments weighing 15 times more than any prior roving vehicle.

Curiosity sees Mount Sharp Up Close and gets ‘Brain Transplant’

The Curiosity rover has beamed back the first detailed images of Mount Sharp, offering a stupendous initial view of her ultimate driving goal, and is now in the midst of a crucial “brain transplant” this weekend that will transform her into a fully operational rover.

The science team will direct the six-wheeled Curiosity to begin climbing Mount Sharp at some later date during the rovers’ two year primary mission after traversing and extensively investigating the floor of her landing site inside Gale Crater.

See our mosaic focusing on the base of Mount Sharp using three full resolution images snapped by the Navcam navigation camera located on the newly erected camera and instrument mast with colorization based on the 34 millimeter Mastcam color camera.

Curiosity came to rest almost flat on the martian surface, but with a slight 3 degree tilt down in the front and the images thus far are taken from that preprogrammed viewpoint, roughly some six miles or so from the base of Mount Sharp.

The terrain is strewn with small pebbles that may stem from a nearby alluvial fan through which liquid water flowed long ago, scientist think. Observations from orbit with NASA’s Mars Reconnaissance Orbiter have identified clay and sulfate minerals in the lower layers of Mount Sharp, indicating a wet history. At higher elevations, scientists hope to discover a boundary layer and indications of what led to the “Great Dessication Event” and loss of liquid water on the ancient Martian surface.

This weekend Curiosity has also begun transmitting spectacular hi res Mastcam images that will far exceed anything else thus far. Here is the Mastcam 360 pano as assembled by NASA so far:

But before the car-sized robot can actually rove around, reach out with her 7 foot (2 meter) long instrument loaded arm and scoop up samples for analysis by the on board chemistry labs she needs the software smarts to accomplish the science tasks.

With all the initial post landing objectives accomplished, engineers at NASA’s Jet Propulsion Lab in Pasadena, Calif., are spending 4 Sols, or Martian days, bracketing this weekend to upload a new software package named “R10” that is optimized for surface operations and will replace the current “R9” package.

“We designed the mission from the start to be able to upgrade the software as needed for different phases of the mission,” said Ben Cichy of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., chief software engineer for the Mars Science Laboratory mission. “The flight software version Curiosity currently is using [R9] was really focused on landing the vehicle. It includes many capabilities we just don’t need any more. It gives us basic capabilities for operating the rover on the surface, but we have planned all along to switch over after landing to a version of flight software that is really optimized for surface operations.”

Software on both the primary and backup computers is being carefully upgraded in step by step stages. He said an initial “toe dip” on Friday to test the upgrade was the first step.

“R10 is optimized for surface operations and has what the science team wants. It’s being downloaded over the next four Sols to enable this fantastic mission,” Cichy said at a JPL news briefing on August 10. They will stand down on science for the next four Sols during the installation.

“Right now, we have the capability in our basic surface software to check out the health of the instruments, but we don’t really have the capability to go and make the full use of all this great hardware we shipped to Mars.”

“So the R10 software gives us the capability to use the robotic arm fully, to use the drill, to use the dust removal tool, to use the whole sampling chain and injest the samples and analyze them, all this exciting stuff this mission will do.”

“Curiosity is a Martian mega rover and born to drive ! R10 gives us the ability to drive autonomously and use images to detect hazards and drive safely.”

So far, the software upgrade is going as planned this weekend.

Curiosity made an unprecedented pinpoint landing inside Gale Crater on Aug. 5/6 using the rocket powered “Sky Crane” descent stage that lowered Curiosity by cables onto the Red Planet’s surface exactly as planned on the plains astride Mount Sharp just a few miles from the base of the gigantic mountain.

Mount Sharp covers much of the interior of the 96 mile wide (154 km) Gale Crater. The peak of the 3.4 mile (5.5 km) high layered mountain is taller than Mount Whitney in California.

Curiosity lead scientist John Grotzinger calls this place “The Mojave Desert” of Mars– that’s the sweet spot where NASA’s huge new Curiosity rover landed only 3 Sols, or days ago, and looks so “Earth-like”.

See above and below our new 3 frame panoramic mosaic showing Curiosity with a dramatic “Mojave Desert” backdrop – in false color and black and white – assembled from new pictures received overnight at JPL.

With her camera mast erected, Curiosity is beginning to beam back a flood of spectacular images and giving us the first detailed view of her new surroundings from her touchdown point inside Gale Crater on Mars beside a 3.4 mile (5.5 km) high layered mountain nicknamed Mount Sharp.

Overnight, Curiosity sent back many more full frame pictures from her Navcam navigation camera, including exquisite high resolution views of herself with the eroded rim of Gale Crater over her shoulder.

At Wednesday’s briefing, Grotzinger has ecstatic with the initial set of high resolution images showing Gale crater in the distance, saying;

“The thing that really struck the science team about this image, you would really be forgiven for thinking that NASA was trying to pull a fast one on you and we actually put a rover out in the Mojave Desert and took a picture.

“That’s the part of the rim that’s lowest in elevation, facing the northern lowlands of Mars.”

“The thing that’s amazing about this is to a certain extent the first impression you get is how earth-like this seems, looking at that landscape.”

The terrain is strewn with small pebbles that the team hypothesizes may stem from a nearby alluvial fan through which liquid water flowed long ago and is exactly why they chose Gale Crater as Curiosity’s landing site.

“The sedimentary materials, all those materials are derived from erosion of those mountains there, that’s the source region for this material,” Grotzinger said. “It’s really kind of fantastic.”

The first 360 color panorama from the Mastcam cameras are expected soon.

Mount Sharp on Mars: 1st 2-D and 3-D Views of Curiosity’s Ultimate Mountain Goal

Image Caption: Clear View on Mars – This image comparison shows a view through a Hazard-Avoidance camera on NASA’s Curiosity rover before and after the clear dust cover was removed.

Image credit: NASA/JPL-Caltech

Curiosity, NASA’s new car sized rover on Mars has sent back her first breathtaking views of Mount Sharp, the huge nearby mountain that enticed scientists to set Gale Crater as her touchdown goal.

And already within the first 2 Sols, or martian days, the rover has beamed back magnificent 2D and 3 D vistas of the landscape surrounding her.

The unprecedented rocket powered “Sky Crane” descent maneuver that lowered Curiosity by cables upon the Red Planet’s surface rover with pinpoint accuracy, set her down in a position inside Gale Crater that fortuitously pointed her front Hazard Avoidance (Hazcam) cameras towards a stupendous panoramic view of Mount Sharp.

The terrain is strewn with small pebbles that may stem from a nearby alluvial fan through which liquid water flowed long ago, scientist think.

The top image set shows the spectacular side by side views of Mount Sharp before and after the protective dust covers were popped off.

Mount Sharp is taller than Mount Ranier, the tallest mountain in the US in the lower 48 states. It’s about 3.5 miles (5.5 km) high.

Curiosity is roughly 6 km distant from Mount Sharp, as the martian crow flies.

The image below is the first full resolution Hazcam version of Mount Sharp.

Curiosity’s Early Views of Mars. This full-resolution image shows one of the first views from NASA’s Curiosity rover, which landed on Mars the evening of Aug. 5 PDT (early morning hours Aug. 6 EDT).

Curiosity Beams 1st Color Image from Mars

Image caption: This murky view from Curiosity shows the martian landscape looking north to the rim from inside the Gale Crater landing site and is her first color image beamed back to Earth.

NASA’s Curiosity Mars rover has beamed back her first color view since touchdown, showing a view of the alien landscape pointing northward towards the eroded rim of Gale crater.

The picture was snapped by the rovers Mars Hand Lens Imager (MAHLI) camera on the afternoon of the first day after the pinpoint landing – signified as Sol 1 on Aug. 6, 2012.

The MAHLI image looks murky because the protective dust cover is still in place and is coated with a film of martian dust sprayed up by the descent retrorockets during the terminal phase of the hair-raising landing on Aug 5/6.

The camera’s dust cover is intentionally transparent so that initial images can still be snapped through the cover before it’s popped off in about a week.

MAHLI is located on the turret at the end of the rover’s 8 foot long robot arm which has been stowed in place on the front left side of Curiosity since long before the Nov. 26 liftoff from Cape Canaveral, Florida.

In the stowed position, MAHLI is rotated about 30 degrees as seen in the image below. The top image has been rotated to correct for the tilt and shows the sky “up” as Curiosity is actually sitting on the Martian surface.

During her 2 year prime mission, Curiosity’s goal is to determine if Mars was ever capable of supporting microbial life, past or present and to search for the signs of life in the form of organic molecules with a payload of 10 science instruments weighing 15 times more than any prior roving vehicle.

Curiosity is the 3rd generation of NASA rover’s delivered to the Red Planet

As NASA’s Curiosity Mars Science Lab (MSL) was in the final stages of her flawless but harrowing decent to Gale Crater on Mars overnight (Aug. 5/6) employing the never-before-used rocket powered sky crane descent stage, dramatic movie-like imagery of the plunge was being recorded by MARDI, the Mars Descent Imager camera positioned on the belly of the rover and pointed downwards.

The first low resolution MARDI images and video (above and below) were beamed back to Earth just hours after landing and clearly show the jettisoning of the heat shield moments after it sprung loose to expose Curiosity and MARDI for landing.

“We see the heat shield falling away about 2 minutes and 30 seconds from touchdown,” said Mike Malin, MARDI Principal Investigator from Malin Space Systems at a post-landing news briefing today (Aug. 6). “The heat shield is about 16 meters (50 ft) away in the image and 4.5 m (15 ft) across.”

“I’m very excited to be at Gale Crater”.

“So far we have received about 297 thumbnail images (192 x 144 pixels) so far and created a stop motion video. MADRI was collecting images at 4 frames per second. In the final frames you can see dust being kicked up the rocket engines.”
Curiosity landed at 1:32 on Aug. 6, EDT (11:32 p.m. Aug. 5, PDT), near the foot of a mountain three miles(5 km) tall inside Gale Crater, 96 miles (154 km) in diameter.

“The image sequence received so far indicates Curiosity had, as expected, a very exciting ride to the surface,” said Mike Malin, imaging scientist for the Mars Science Lab mission from Malin Space Systems in San Diego. “But as dramatic as they are, there is real other-world importance to obtaining them. These images will help the mission scientists interpret the rover’s surroundings, the rover drivers in planning for future drives across the surface, as well as assist engineers in their design of forthcoming landing systems for Mars or other worlds.”

“A good comparison is to that grainy onboard film from Apollo 11 when they were about to land on the moon,” said Malin.

Over 1500 hundred more low and high resolution MARDI images (1600 x 1200 pixels) will be sent back over the next few weeks to make a full frame animation and will provide the most complete and dramatic imagery of a planetary landing in the history of exploration.

The team has been able to determine Curiosity’s location to “within” about 1 meter says Malin, by matching the MARDI and MRO HiRISE images as well as the Hazcam images.

“So far the rover is healthy and we are ecstatic with its performance,” said Jennifer Trospher, MSL mission manager

The next steps are to deploy the high gain antenna (HGA), raise the mast with the higher resolution cameras and continue to check out the mechanical and electrical systems as well the science instruments as the rover is transitioned to surface operations mode.

US President Barack Obama hailed the spectacular landing success of NASA’s Curiosity rover on Aug. 6 inside Gale Crater and eagerly awaits the discoveries to come. More accolades for Curiosity and the rover team are pouring in from all across the globe.

The White House issued the following statement:

Statement by the President on Curiosity Landing on Mars

“Tonight, on the planet Mars, the United States of America made history.

The successful landing of Curiosity – the most sophisticated roving laboratory ever to land on another planet – marks an unprecedented feat of technology that will stand as a point of national pride far into the future. It proves that even the longest of odds are no match for our unique blend of ingenuity and determination.

Tonight’s success, delivered by NASA, parallels our major steps forward towards a vision for a new partnership with American companies to send American astronauts into space on American spacecraft. That partnership will save taxpayer dollars while allowing NASA to do what it has always done best – push the very boundaries of human knowledge. And tonight’s success reminds us that our preeminence – not just in space, but here on Earth – depends on continuing to invest wisely in the innovation, technology, and basic research that has always made our economy the envy of the world.

I congratulate and thank all the men and women of NASA who made this remarkable accomplishment a reality – and I eagerly await what Curiosity has yet to discover.”

The 1 ton Mini Cooper sized robot geologist and roving chemistry lab is seeking the signs of life on Mars and is loaded with 165 pounds of the most sophisticated science instruments ever delivered to the surface of the Red Planet.

During a two-year prime mission, Curiosity the rover will investigate whether the region has ever offered conditions favorable for microbial life, and search for organic molecules – the chemical ingredients for life.

Long Live American Curiosity – Now We Start Exploring Mars

“Welcome to Mars,” said Charles Elachi, Director of the Jet Propulsion Laboratory, Pasadena, Calif., following the dramatic and successful touchdown of Curiosity on the Red Planet at 1:32 AM EDT Aug. 6 (10:32 PM Aug 5). “Tonight was a great drama. We did the landing. Tomorrow we start exploring Mars and make new discoveries every day. Our Curiosity has no limits and we will explore the solar system.”

Tumultuous and long lasting jubilation erupted at Mission Control at JPL when the spectacular pinpoint landing success was announced and continued during the post landing news briefing at JPL.

NASA’s Curiosity Mars Science Lab (MSL) safely survived the harrowing plunge and nail biting descent through the Martian atmosphere known as the “7 minutes of Terror”. After hitting the thin atmosphere at 13,200 MPH (5,900 m/s), the robot perfectly executed the unprecedented entry, descent and landing (EDL) sequence utilizing a rocket powered guided descent, supersonic parachutes and then culminating in the never before tried “sky crane maneuver” and helicopter-like touch down at 0 MPH barely 7 minutes later.

Curiosity landed near the foot of a layered mountain three miles (5 km) tall and 96 miles(154 km) in diameter inside Gale Crater which may once have contained a lake. She relayed a few initial thumbnail pictures within minutes after touchdown via NASA’s Mars Odyssey orbiter.

Larger images showing the Gale crater rim were sent back during the 2nd Odyssey over flight about 2 hours later. Many higher resolution images will be transmitted back to Earth in the coming days including the first 360 degree panorama.

“Curiosity’s landing site is beginning to come into focus,” said John Grotzinger, project manager of NASA’s Mars Science Laboratory mission, at the California Institute of Technology in Pasadena. “In the image (above), we are looking to the northwest. What you see on the horizon is the rim of Gale Crater. In the foreground, you can see a gravel field. The question is, where does this gravel come from? It is the first of what will be many scientific questions to come from our new home on Mars.”

“Long live American Curiosity”, said John Holdren, science advisor to President Obama. “Today on Mars, history was made on Earth. It will stand as an American point of pride far in the future. I want to congratulate the team on behalf of President Obama. Landing Curiosity was the most challenging mission ever attempted in robotic planetary exploration. This 1 ton automobile sized piece of American ingenuity on Mars should put to rest any doubts about American space leadership. Even the longest odds are no match for our gutsy determination.”

Curiosity traveled for over 8 months and more than 352-million-mile (567-million-kilometer) to arrive at Mars since launching from Earth in Nov. 2011.

“Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars. Curiosity, the most sophisticated rover ever built, is now on the surface of the Red Planet, where it will seek to answer age-old questions about whether life ever existed on Mars — or if the planet can sustain life in the future,” said NASA Administrator Charles Bolden.

“This is an amazing achievement, made possible by a team of scientists and engineers from around the world and led by the extraordinary men and women of NASA and our Jet Propulsion Laboratory. President Obama has laid out a bold vision for sending humans to Mars in the mid-2030’s, and today’s landing marks a significant step toward achieving this goal.”

“What a fantastic demonstration of what our nation can accomplish. Thank you team. I am so proud of you. And what an inspiration to our young people. Nothing is harder than landing on Mars. Our leadership will make this world better.”

Curiosity is a 10 foot long (3 m) car-sized robotic geologist. The 1 ton behemoth is a roving chemistry lab with 10 state-of-the-art science instruments that will collect and analyze soil and rock samples and zap rocks from a distance with a laser to search for carbon in the form of organic molecules – the building blocks of life.

“On behalf of the 400 members of the science team we thank everybody involved in this enterprise the landing team,” said John Grotzinger, the MSL Project Scientist of the California Institute of Technology. “There is no greater inspiration to school kids than going to Mars. The cost of MSL for each American is the cost of a movie. That’s a movie I want to see.”

During a 2 year prime mission, she will search for evidence of habitats that could preserve signs of Martian microbial life. She will rove the crater floor seeking evidence of water related phyllosilicates and sulfates and eventually climb up the nearby mountain, nicknamed Mount Sharp.
