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.

For comparison, see Curiosity’s initial wider field post-landing shots of Mount Sharp in 2 D and 3 D from the lower resolution fish-eye Hazcam cameras, here

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.

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.

Curiosity raises Mast and snaps 1st Self Portrait and 1st 360 Panorama

Image Caption: Rover’s Self Portrait -This Picasso-like self portrait of NASA’s Curiosity rover was taken by its Navigation cameras, located on the now-upright mast. The camera snapped pictures 360-degrees around the rover, while pointing down at the rover deck, up and straight ahead. Those images are shown here in a polar projection. Most of the tiles are thumbnails, or small copies of the full-resolution images that have not been sent back to Earth yet. Two of the tiles are full-resolution. Credit: NASA/JPL-Caltech.

The rover Curiosity continues her marathon run of milestone achievements – snapping her 1st self portrait and 1st 360 degree panorama since touchdown inside Gale Crater barely over 2 sols, or Martian days ago.

To take all these new images, Curiosity used a new camera, the just-activated higher resolution navigation cameras (Navcam) positioned on the mast. Several of the new images provide the best taste yet of the stupendous vistas coming soon. See our enhanced Sol 2 mosaic below.

The 3.6 foot-tall (1.1 meter) camera mast on the rover deck was just raised and activated earlier today, Wednesday, Aug. 8.

The mast deployment is absolutely crucial to Curiosity’s science mission. It is also loaded with the high resolution MastCam cameras and the ChemCam instrument with the laser rock zapper.

Most of the images Navcam images beamed back today were lower-resolution thumbnails. But 2 high-resolution Navcams from the panorama and the self portrait were also downlinked and provide the clearest view yet of the breathtaking terrain surrounding Curiosity in every direction.

“The full frame navcams show the north rim of Gale Crater,” said Justin Maki, MSL navcam lead, at a briefing today at JPL. “The Navcam’s are identical to the MER Navcam’s.”

The hi res images also show how the descent thruster excavated the topsoil like Phoenix.

Most of the tiles are thumbnails, or small copies of the full-resolution images that have not been sent back to Earth yet. Two of the tiles near the center are full-resolution. Mount Sharp is to the right, and the north Gale Crater rim can be seen at center. The rover’s body is in the foreground, with the shadow of its head, or mast, poking up to the right. These images were acquired at 3:30 pm on Mars, or the night of Aug. 7 PDT (early morning Aug. 8 EDT). Thumbnails are 64 by 64 pixels in size; and full-resolution images are 1024 by 1024 pixels.

“These Navcam images indicate that our powered descent stage did more than give us a great ride, it gave our science team an amazing freebie,” said John Grotzinger, project scientist for the mission from the California Institute of Technology in Pasadena. “The thrust from the rockets actually dug a one-and-a-half-foot-long [0.5-meter] trench in the surface. It appears we can see Martian bedrock on the bottom. Its depth below the surface is valuable data we can use going forward.”

Gale Crater is unlike anything we’ve seen before on Mars.

It also distinctly reminded Grotzinger of Earth and looked to him like the rover set down in the Mojave desert. “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.”

Curiosity carries 10 science instruments with a total mass 15 times as large as the science payloads on NASA’s Mars rovers Spirit and Opportunity. Some of the tools, such as a laser-firing instrument for checking rocks’ elemental composition from a distance, are the first of their kind on Mars. Curiosity will use a drill and scoop, which are located at the end of its robotic arm, to gather soil and powdered samples of rock interiors, then sieve and parcel out these samples into the rover’s analytical laboratory instruments.

So far everything is going very well with Curiosity’s mechanical and instrument checkout. And there is even more power than expected from the RTG nuclear power source.

“We have more power than we expected and that’s going to be fantastic for being able to keep the rover awake longer,” said Mission manager Jennifer Trosper of JPL.

A Panorama of Curiosity’s Surroundings

Taken this morning (mission Sol 2) with the rover’s left Navcam, here’s a high-res panorama of Curiosity’s view at its landing site within Gale crater. The wide-angle view was assembled from two separate raw images, so while the mountainous rim of the crater is lined up horizontally there’s some distortion in alignment of objects closer to the rover due to the angle of the Navcam lens. Still, it’s a very cool view of Curiosity’s surroundings!

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.

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.

Here’s the first 3D version of Mount Sharp assembled from both front cameras.

The anaglyph was made from a stereo pair of Hazard-Avoidance Cameras on the front of the rover. Mount Sharp, a peak that is about 5.5 kilometers (3.4 miles) high, is visible rising above the terrain, though in one “eye” a box on the rover holding the drill bits obscures the view. This image was captured by Hazard-Avoidance cameras on the front of the rover at full resolution shortly after the rover landed. It has been linearized to remove the distorted appearance that results from its fisheye lens. Credit: NASA/JPL-Caltech

Curiosity’s Dramatic MARDI Descent Movie

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

Image Caption: This 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).

“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.

When are the First Pictures Expected from Curiosity

Image Caption: This graphic shows the locations of the cameras on NASA’s Curiosity rover. The rover’s mast features seven cameras: the Remote Micro Imager, part of the Chemistry and Camera suite; four black-and-white Navigation Cameras (two on the left and two on the right) and two color Mast Cameras (Mastcams). Image credit: NASA/JPL-Caltech

If all goes well with the high stakes descent, the first images from the 1 ton Curiosity rover on the Martian surface could be received in the first few minutes after touchdown inside Gale Crater beside a huge mountain with layered sediments – now less than a day away.

It all depends on whether Curiosity successfully establishes a communications link with NASA’s Mars Odyssey signal relay spacecraft as the resilient orbiter simultaneously flies over the landing site and transmits the vital data indicating “Yes I’m Alive” to tracking stations back on Earth for analysis by anxiously waiting engineers at NASA’s Jet Propulsion Lab in Pasadena, Calif.

“We are expecting Odyssey to relay good news,” said Steve Sell of the JPL engineering team that developed and tested the mission’s complicated and never before used “sky crane” landing system. “That moment has been more than eight years in the making.”

The initial pictures would be reduced-resolution fisheye black-and-white images from the Hazard-Avoidance cameras (Hazcams), attached to the front and rear body of the rover.

“On the first night we expect the first low resolution black-and -white images from the rear hazcam, thumbnails about 50 x 50 pixels” said JPL’s Richard Cook, deputy project manager for Curiosity at today’s (Aug. 4) news briefing for reporters at JPL. “The Mars Odyssey relay will continue for 2 to 5 minutes after landing. Later that first night we hope to get a 512 x 512 pixel image looking out the rear of the rover.”

The hazcam cameras are covered with protective clear dust covers so the initial pictures might be taken through the covers if they haven’t popped off yet, Cook explained.

“The next chance to receive data and pictures comes 2 hours later post-landing during the second Odyssey over flight,” he added. “The next opportunity after that comes about 12 hours later.”

Initial thumbnail images from the rovers Mars Descent Imager (MARDI) camera,located on the belly of the rover, during the descent to the Red Planet’s surface are expected a day later on Aug. 7. These images will help pinpoint Curiosity’s exact location.

The team expects to deploy the rover’s mast with the higher resolution cameras on Aug. 7. Curiosity would then begin acquiring a 360 degree stereo panorama with the Navcam cameras the next day on Aug. 8.

The first color images are expected around Aug 8 from the Mars Hand Lens Imager, or MAHLI, one of five devices on the rover’s Inspector Gadget-like robotic arm. MAHLI will still be in the stowed position when it snaps the initial pictures.

But the whole plan depends on a successful landing and engineering checkout and instrument deployments along with no significant technical problems.

Navigators guiding NASA’s Curiosity Mars Science Lab (MSL) are threading the needle in these final 24 hours as she accelerates towards a miniscule target box barely 2 miles by 7 miles (2.8 by 11.5 kilometers) wide.

“We’re now right on target to fly through the eye of a needle, that is, our target at the top of the Mars atmosphere,” said MSL mission manager Arthur Amador, JPL, at the briefing. “The target is a box that’s 3 kilometers (1.9 miles) by 12 kilometers (7.5 miles) in dimension. And we’re flying right through it.”

Image Caption: Eye of the Needle – This graphic shows how navigators steering NASA’s Mars Science Laboratory capsule — with the Curosity rover tucked inside — are aiming for a pinpoint location above Mars. They liken it to threading the eye of a needle. Navigators are aiming for a point inside of a target box that is 1.7 by 7.15 miles (2.8 by 11.5 kilometers) wide above the Red Planet. Mars’ gravity well, which has been precisely calculated, will pull the spacecraft into the Martian atmosphere. The plane in which MSL has been traveling toward Mars — labeled trajectory plane — hits what is known as the B-plane at a 90 degree angle. The B plane is the plane perpendicular to the velocity of the spacecraft when it is far away from Mars. It is used for maneuver targeting. The northward direction of Mars’ pole is also indicated. Credit: NASA/JPL-Caltech

As of Saturday evening, Aug 4, MSL has cut its distance from Mars in half in the past day. MSL is the same distance from Mars as the Earth is from the Moon, around 250,000 miles (400,000 km) and closing at more than 8000 MPH (about 3,600 meters per second).

“Right now, I’m closer to Mars than the moon is to Earth,” Curiosity just tweeted.

After the nail biting entry, descent and landing (EDL) , the 6 wheeled rover Curiosity is scheduled to touchdown inside Gale Crater at about 1:31 a.m. EDT (531 GMT) early on Aug. 6 (10:31 p.m. PDT on Aug. 5).

The 10 feet (3 meters) long mini Cooper sized Curiosity is loaded with 10 state-of-the-art science experiments that will search for organic molecules – the building blocks of life. She is the most sophisticated robot ever sent to the surface of another world. Curiosity will investigate the Red Planet like never before and look for signs of Martian microbial life and habitable zones by analyzing soil and rock samples with high powered analytical chemistry instruments.

And even the weather is cooperating.

“The active dust storm we saw south of Gale crater has now evolved into a harmless dust cloud. Basically, the poofed remnants of what was that dust storm. Mars is cooperating by providing good weather for landing,” said JPL’s Ashwin Vasavada, deputy project scientist for Curiosity.

“The team has done everything possible to make it a success. It is scary and risky. I am proud of the team,” said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters at the JPL briefing. “Risk exists.”

“The human spirit is driven by these kind of challenges. These challenges force us to explore our surroundings and understand what’s out there. And look at “Are we Alone?”

When Will We Hear From Curiosity?

Just over a day from now the Mars Science Laboratory mission will arrive at Mars, its nine-month journey through space culminating in a harrowing “seven minutes of terror” that will place the Curiosity rover safely onto Mars’ surface within Gale crater. Although the world will be watching, there’s a chance that nobody will know exactly what happened to Curiosity for quite some time — even if everything goes perfectly.

This cool animation from NASA’s Jet Propulsion Laboratory shows why “simple” communication between two neighboring planets is still tricky business. (Hey, it’s not called rocket science for nothing!)
