Pasadena, U.S.A. — NASA’s Mars rover Curiosity has begun driving from its landing site, which scientists announced today they have named for the late author Ray Bradbury. Making its first movement on the Martian surface, Curiosity’s drive combined forward, turn and reverse segments. This placed the rover roughly 20 feet (6 meters) from the spot where it landed August 6th.

NASA has approved the Curiosity science team’s choice to name the landing ground for the influential author who was born 92 years ago today and died this year. The location where Curiosity touched down is now called Bradbury Landing. “This was not a difficult choice for the science team,” said Michael Meyer, NASA program scientist for Curiosity. “Many of us and millions of other readers were inspired in our lives by stories Ray Bradbury wrote to dream of the possibility of life on Mars.”

The drive confirmed the health of Curiosity’s mobility system and produced the rover’s first wheel tracks on Mars, documented in images taken after the drive. During a news conference at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif., the mission’s lead rover driver, Matt Heverly, showed an animation derived from visualization software used for planning the first drive. “We have a fully functioning mobility system with lots of amazing exploration ahead,” Heverly said.

Curiosity will spend several more days of working beside Bradbury Landing, performing instrument checks and studying the surroundings, before embarking toward its first driving destination approximately 1,300 feet (400 meters) to the east-southeast.”

Curiosity is a much more complex vehicle than earlier Mars rovers. The testing and characterization activities during the initial weeks of the mission lay important groundwork for operating our precious national resource with appropriate care,” said Curiosity Project Manager Pete Theisinger of JPL. “Sixteen days in, we are making excellent progress.”

The science team has begun pointing instruments on the rover’s mast for investigating specific targets of interest near and far. The Chemistry and Camera (ChemCam) instrument used a laser and spectrometers this week to examine the composition of rocks exposed when the spacecraft’s landing engines blew away several inches of overlying material.

The instrument’s principal investigator, Roger Weins of Los Alamos National Laboratory in New Mexico, reported that measurements made on the rocks in this scoured-out feature called Goulburn suggest a basaltic composition. “These may be pieces of basalt within a sedimentary deposit,” Weins said.

Curiosity began a two-year prime mission on Mars when the Mars Science Laboratory spacecraft delivered the car-size rover to its landing target inside Gale Crater on August 5 PDT (August 6 EDT). The mission will use 10 science instruments on the rover to assess whether the area has ever offered environmental conditions favorable for microbial life.

In a career spanning more than 70 years, Ray Bradbury inspired generations of readers to dream, think and create. A prolific author of hundreds of short stories and nearly to 50 books, as well as numerous poems, essays, operas, plays, teleplays, and screenplays, Bradbury was one of the most celebrated writers of our time.

His groundbreaking works include “Fahrenheit 451,” “The Martian Chronicles,” “The Illustrated Man,” “Dandelion Wine,” and “Something Wicked This Way Comes.” He wrote the screenplay for John Huston’s classic film adaptation of “Moby Dick,” and was nominated for an Academy Award. He adapted 65 of his stories for television’s “The Ray Bradbury Theater,” and won an Emmy for his teleplay of “The Halloween Tree.”

JPL manages the Mars Science Laboratory Curiosity for NASA’s Science Mission Directorate in Washington. The rover was designed, developed and assembled at JPL.

This was quickly followed by a second picture its own shadow. These are the first of many photographs and samples expected from the new rover. The mission, the latest in the line from the Mars Science Laboratory (which created Sojourner in 1997, Spirit in 2004, and Opportunity in 2004), is expected to last about two years.

The landing in itself was a small miracle, involving a supersonic parachute, a shedded heat shield, and a rocket-powered “sky crane,” but was ultimately flawless. The entire SUV-sized land rover, including all of its equipment, will be checked over by the lab scientists before beginning its journey.

The cost of the project was about $2.5 billion, $900 million over the original estimate. The project also ran 2 years late, after 14 years of planning. NASA is not truly worried about the cost. John Grotzinger, one of the project scientists, said “This whole enterprise comes out to be the cost of a movie. And that’s a movie I want to see.”

Curiosity was launched in November of last year, equipped with the technology to analyze rocks and soil samples, and take pictures, in the hope of confirming or denying whether Mars could support life forms at some point. The intention is to find the organic molecules that are necessary to create life, such as carbon that could contain fossilized life forms.

The rover will also check the air for signs of current existing life, like methane gas. The first stop for Curiosity is Gale Crater, which was once possibly a lake, and eventually, about a year from now, Mount Sharp in the center of the crater. The layers of rock in the mountain will give a lot of information about the planet’s history.

But scientists insist even this cannot determine if life existed on Mars, only that it is possible.

NASA is extremely proud of their success after previous failures, and are anxious to see what Curiosity will report. NASA administrator Charles Bolden said, “It’s just absolutely incredible, and it’s a huge day for the American people. Everybody in the morning should be sticking their chest out and saying, ‘That’s my rover on Mars,’ because it belongs to everyone.”

“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,” President Barack Obama commented.

US citizens eagerly await more information on Curiosity’s journey, marking the day that the exploration into our solar system was brought to a whole new level.

Washington, U.S.A – NASA-funded research on Mars meteorites that landed on Earth shows strong evidence that very large molecules containing carbon, which is a key ingredient for the building blocks of life, can originate on the Red Planet. These macromolecules are not of biological origin, but they are indicators that complex carbon chemistry has taken place on Mars.

Researchers from the Carnegie Institution for Science in Washington who found reduced carbon molecules now have better insight into the chemical processes taking place on Mars. Reduced carbon is carbon that is bonded to hydrogen or itself. Their findings also may assist in future quests for evidence of life on the Red Planet. The findings are published in Thursday’s online edition of Science Express.

“These findings show that the storage of reduced carbon molecules on Mars occurred throughout the planet’s history and might have been similar to processes that occurred on the ancient Earth,” said Andrew Steele, lead author of the paper and researcher from Carnegie. “Understanding the genesis of these non-biological, carbon-containing macromolecules on Mars is crucial for developing future missions to detect evidence of life on our neighboring planet.”

Finding molecules containing large chains of carbon and hydrogen has been one objective of past and present Mars missions. Such molecules have been found previously in Mars meteorites, but scientists have disagreed about how the carbon in them was formed and whether it came from Mars. This new information proves Mars can produce organic carbon.

“Although this study has not yielded evidence that Mars has or once may have supported life, it does address some important questions about the sources of organic carbon on Mars,” said Mary Voytek, director of NASA’s Astrobiology Program at the agency’s Headquarters in Washington. “With the Curiosity rover scheduled to land in August, these new research results may help Mars Science Laboratory scientists fine-tune their investigations on the surface of the planet by understanding where organic carbon may be found and how it is preserved.”

Scientists have theorized that the large carbon macromolecules detected on Martian meteorites could have originated from terrestrial contamination from Earth or other meteorites, or chemical reactions or biological activity on Mars.

Steele’s team examined samples from 11 Martian meteorites from a period spanning about 4.2 billion years of Martian history. They detected large carbon compounds in 10 of them. The molecules were found inside grains of crystallized minerals.

Using an array of sophisticated research techniques, the team was able to show that at least some of the macromolecules of carbon were indigenous to the meteorites themselves and not contamination from Earth.

The team next looked at the carbon molecules in relation to other minerals in the meteorites to see what kinds of chemical processing these samples endured before arriving on Earth. The crystalline grains encasing the carbon compounds provided a window into how the carbon molecules were created. Their findings indicate that the carbon was created by volcanic activity on Mars and show that Mars has been doing organic chemistry for most of its history.

In a separate paper published by American Mineralogist, Steele and his team report their findings on the same meteorite announced in 1996 to contain possible — but subsequently discounted — relics of ancient biological life on Mars. Called ALH84001, the meteorite was found to also contain organic macromolecules of non-biological origin.

The Steele team’s research indicates that Mars does have a pool of reduced carbon. Their findings should help scientists involved in current and future Mars missions distinguish non-biologically formed carbon molecules from potential life.
