Mars Rover Curiosity  was captured by NASA's Mars Reconnaissance Orbiter (MRO) on its way to Mount Sharp

Mars Rover Curiosity Rover captured by NASA's Mars Reconnaissance Orbiter (MRO) as it makes its way to Mount Sharp, leaving a weaving set of tracks in its wake. The image released today by NASA scientists, shows Rover making its way across the planet, leaving tracks back to a dark, blast spot on the surface of Mars. That spot called the 'Bradbury Landing' is where Mars Rover Curiosity landed on Mars, named after the late science fiction author Ray Bradbury.

Mars rover Curiosity captures 1.3-gigapixel panorama of the Red Planet

"The image, titled Billion-Pixel View from Curiosity at Rocknest, was assembled from almost 900 photos captured by Curiosity between October 5 and November 16 last year. 850 photos came from Mastcam 100, the 100mm (telescopic) camera atop Curiosity’s mast, with 21 supplementary images provided by Mastcam 34 (the wide-angle camera that sits next to Mastcam 100) and 25 black-and-white frames from Curiosity’s Navigation Camera. Because the photos were captured over a number of days, you can see quite a few variations caused by the angle of the Sun and the dusty atmosphere. As an interesting aside, it’s fun to note that each Mastcam is only equipped with a 2-megapixel sensor — proof that the megapixel myth is indeed a myth. 1.3 billion pixels, in case you were wondering, is 1.3 gigapixels — or 1,300 megapixels."

PASADENA, Calif. -- A billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity, offers armchair explorers a way to examine one part of the Red Planet in great detail.

The first NASA-produced view from the surface of Mars larger than one billion pixels stitches together nearly 900 exposures taken by cameras onboard Curiosity and shows details of the landscape along the rover's route.
The 1.3-billion-pixel image is available for perusal with pan and zoom tools at: http://mars.nasa.gov/bp1/ and a scaled down version (~159MB) is available for direct download here: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA16919 .


The full-circle scene surrounds the site where Curiosity collected its first scoops of dusty sand at a windblown patch called "Rocknest," and extends to Mount Sharp on the horizon.

"It gives a sense of place and really shows off the cameras' capabilities," said Bob Deen of the Multi-Mission Image Processing Laboratory at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "You can see the context and also zoom in to see very fine details."


Deen assembled the product using 850 frames from the telephoto camera of Curiosity's Mast Camera instrument, supplemented with 21 frames from the Mastcam's wider-angle camera and 25 black-and-white frames -- mostly of the rover itself -- from the Navigation Camera. The images were taken on several different Mars days between Oct. 5 and Nov. 16, 2012. Raw single-frame images received from Curiosity are promptly posted on a public website at: http://mars.jpl.nasa.gov/msl/multimedia/raw/ . Mars fans worldwide have used those images to assemble mosaic views, including at least one gigapixel scene.

The new mosaic from NASA shows illumination effects from variations in the time of day for pieces of the mosaic. It also shows variations in the clarity of the atmosphere due to variable dustiness during the month while the images were acquired.

NASA's Mars Science Laboratory project is using Curiosity and the rover's 10 science instruments to investigate the environmental history within Gale Crater, a location where the project has found that conditions were long ago favorable for microbial life.
Malin Space Science Systems, San Diego, built and operates Curiosity's Mastcam. JPL, a division of the California Institute of Technology in Pasadena, manages the project for NASA's Science Mission Directorate in Washington and built the Navigation Camera and the rover.

After investigating for ten months at the plains, NASA’s Mars rover Curiosity is set to move toward the mountains in search for favorable habitats that could be suitable for microbial life.
According to deputy project scientist Joy Crisp from NASA's Jet Propulsion Laboratory, the journey to “Mount Sharp” will be a long one. "This truly is a mission of exploration, so just because our end goal is Mount Sharp does not mean we are not going to investigate interesting features along the way."
"We're going to keep our eyes open as we drive and if we in fact drive past something that's amazing, we might actually turn around and go back and check it out, but there's nothing that we see from orbit that's like some super-compelling clue to life or something like that," Crisp said.
"What we have is a real desire to get to Mount Sharp.”

Considered as the “biggest turning point since landing” of Curiosity, NASA hopes that investigations at “Mount Sharp” will unearth new evidence of life-friendly habitats on Mars. From the images of Mount Sharp taken from orbit and images Curiosity has taken from a distance, scientists have figured out many layers in the area, which may offer significant information on how the ancient Martian environment changed and evolved.

Scientists said the Mars Science Laboratory mission has already accomplished its main science objective. Analysis of rock powder from the first drilled rock target, "John Klein," provided evidence that an ancient environment in Gale Crater had favorable conditions for microbial life -- the essential elemental ingredients, energy and ponded water that was neither too acidic nor too briny.

Ageing Mars rover Opportunity has found evidence that the conditions for ancient life once existed on the Red planet.

Mars Rover Opprotunity has been wandering on Mars since 2004, and it is still producing useful science.
Its remarkable longevity has astounded and delighted Nasa officials, who initially expected that it would last for just 90 Martian days. Instead it is continuing to roll along the surface, 37 times longer than anybody thought it would.

Its latest discovery is one of its most exciting, Nasa officials said: an area of rock which was clearly weathered by large amounts of water, indicating that the conditions for life once existed on the planet.
The exposed  rock ( called "Esperance") is unlike any the rover has previously found, fractured and weathered by conditions that were "possibly favorable for life", Nasa said. The new pictures were taken at Cape York, an area on the rim of the massive Endeavour crater.

Could Radiation Harm Astronauts Traveling to Mars?

Astronauts who travel to Mars one day could be exposed to dangerous levels of radiation during their trip, even if shielding techniques are used, a new study shows.




When the Mars Science Laboratory launched on Nov. 26, 2011, it began a 350-million-mile (560 million kilometers) trip to the surface of the Red Planet. During its voyage, a group of researchers, including Southwest Research Institute scientist Cary Zeitlin, monitored exactly how much radiation a piece of science hardware on the Mars rover Curiosity was exposed to over the 253-day journey from Earth to Mars.

"In space, it's between a 100 and 1,000 times higher dose rate [of radiation] than on Earth," Zeitlin noted. "It's highly uncertain what the health risk is from these exposures."

"In terms of accumulated dose, it's like getting a whole-body CT scan once every five or six days," said Dr. Cary Zeitlin, a principal scientist in SwRI's Space Science and Engineering Division and lead author of Measurements of Energetic Particle Radiation in Transit to Mars on the Mars Science Laboratory, scheduled for publication in the journal Science on May 31.


"Understanding the radiation environment inside a spacecraft carrying humans to Mars or other deep space destinations is critical for planning future crewed missions," Zeitlin said. "Based on RAD measurements, unless propulsion systems advance rapidly, a large share of mission radiation exposure will be during outbound and return travel, when the spacecraft and its inhabitants will be exposed to the radiation environment in interplanetary space, shielded only by the spacecraft itself."

Zeitlin, whose study is detailed in the journal Science this week, collected the data with his team by turning on the Radiation Assessment Detector (RAD) instrument while Curiosity was in flight. The instrument was active from 10 days after launch until about three weeks before landing.

Curiosity is back, baby!

Is there life on Mars? Why the question still eludes NASA...

Is there life on Mars?
Why the question still eludes us after 40 years of  NASA discovery on Mars?

 NASA is slowly learning where to look for microbes on the Red Planet, but there are no answers yet

 By Carl Franzen

"For NASA, nearly 40 years after it first landed on Mars, it remains too early to make that call. The agency right now is just concerned with proving habitability, which the Curiosity rover seems to have effectively done. NASA's next mission to Mars, an orbital craft called MAVEN, is due to launch later this year to study Mars's atmosphere. The mission after that, InSight, due to launch in 2016, will be another lander that will bore deeper into Mars than even Curiosity can, revealing yet more data on Mars' past. Still, it's doubtful either of these missions will settle the question of life once and for all."
