NASA ready for November launch of car-size Mars rover
The Mars Science Laboratory mission's rover, Curiosity, is prepared for final integration into the complete NASA spacecraft in this photograph taken inside the Payload Hazardous Servicing Facility at NASA Kennedy Space Center, Fla.

( -- NASA's most advanced mobile robotic laboratory, which will examine one of the most intriguing areas on Mars, is in final preparations for a launch from Florida's Space Coast at 10:25 a.m. EST (7:25 a.m. PST) on Nov. 25.

The Mars Science Laboratory mission will carry Curiosity, a rover with more scientific capability than any ever sent to another planet. The rover is now sitting atop an Atlas V rocket awaiting liftoff from .

"Preparations are on track for launching at our first opportunity," said Pete Theisinger, Mars Science Laboratory project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "If weather or other factors prevent launching then, we have more opportunities through Dec. 18."

Scheduled to land on the Red Planet in August 2012, the one-ton rover will examine Gale Crater during a nearly two-year prime mission. Curiosity will land near the base of a layered mountain 3 miles (5 kilometers) high inside the crater. The rover will investigate whether environmental conditions ever have been favorable for development of and preserved evidence of those conditions.

"Gale gives us a superb opportunity to test multiple potentially habitable environments and the context to understand a very long record of early environmental evolution of the planet," said John Grotzinger, project scientist for the Mars Science Laboratory at the California Institute of Technology in Pasadena. "The portion of the crater where Curiosity will land has an alluvial fan likely formed by water-carried sediments. Layers at the base of the mountain contain clays and sulfates, both known to form in water."

This oblique view of Gale Crater shows the landing site and the mound of layered rocks that NASA's Mars Science Laboratory will investigate. The landing site is in the smooth area in front of the mound. Gale Crater is 96 miles (154 kilometers) in diameter and holds a layered mountain rising about 3 miles (5 kilometers) above the crater floor.

Curiosity is twice as long and five times as heavy as earlier Mars rovers Spirit and Opportunity. The rover will carry a set of 10 weighing 15 times as much as its predecessors' science payloads.

A mast extending to 7 feet (2.1 meters) above ground provides height for cameras and a laser-firing instrument to study targets from a distance. Instruments on a 7-foot-long (2.1-meter-long) arm will study targets up close. Analytical instruments inside the rover will determine the composition of rock and soil samples acquired with the arm's powdering drill and scoop. Other instruments will characterize the environment, including the weather and natural radiation that will affect future human missions.

"Mars builds upon the improved understanding about Mars gained from current and recent missions," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington. "This mission advances technologies and science that will move us toward missions to return samples from, and eventually send humans to, Mars."

The mission is challenging and risky. Because Curiosity is too heavy to use an air-bag cushioned touchdown, the mission will use a new landing method, with a rocket-powered descent stage lowering the rover on a tether like a kind of sky-crane.

The mission will pioneer precision landing methods during the spacecraft's crucial dive through Mars' atmosphere next August to place the onto a smaller landing target than any previously for a Mars mission. The target inside Gale Crater is 12.4 miles (20 kilometers) by 15.5 miles (25 kilometers). Rough terrain just outside that area would have disqualified the landing site without the improved precision.

No mission to Mars since the Viking landers in the 1970s has sought a direct answer to the question of whether life has existed on . Curiosity is not designed to answer that question by itself, but its investigations for evidence about prerequisites for life will steer potential future missions toward answers.

Let's just hope that the build quality is on the same level as JPL's rovers.

I am waiting in exitement to see if the rover can find out more about the methane observations. Apparantly materials the rover is made of, emits methane... Lets hope this is not a hindrance for too long.

Thanks for the interesting story.

As the outermost terrestrial planet, Mars consists mostly of heavy elements (Fe, O, Ni, Si and S) like ordinary meteorites and the Earth.

Mars may also contain a larger fraction of light elements (H, He, C, N) and "strange" heavy elements like Jupiter and the carbon-rich inclusions of carbonaceous meteorites:

The case for local synthesis of the chemical elements",

Will an American or a Russian rocket launch the "advanced mobile robotic laboratory"?

With kind regards,
Oliver K. Manuel

"did JPL make Spirit and Oppertunity??"

Not only did JPL design, build and test the rovers, they are responsible for the design and objectives of the overall mission(s) themselves: http://en.wikiped..._Mission

I had the pleasure of watching the construction of Curiosity and her being loaded into her crate on live video over several days. It gave me a sense of pride to see the next American science explorer being assembled and so lovingly cared for by our American scientists, engineers and technicians. I hope Curiosity encourages many of the next generation of new scientists to go into those fields that will continue the exploration of Mars.

I have downloaded the large file JP2 in black & white image from the HiRise website at
There may be some anomalies in Gale Crater region that could be of great interest. Curiosity is only equipped to gather samples to evaluate and will not be looking for strange anomalies at all. Bacteria and geology is the prime mission. Oh, and meteorology. But I must admit that her design and method of propulsion are superior to Spirit and Opportunity.
R.I.P., Spirit.

Oliver Manuel's recent efforts to plaster and other public news sites with his theories and personal URLs are a bit puzzling, as scientists have a variety of publications available to communicate directly to each other in. My best guess is that he is desperately trying to prop up his legacy in light of his arrest in his university office on 7 charges of rape and sodomy based on allegations by 4 of his own children. The charges have been reduced to one count of felony attempted sodomy, not necessarily because of his innocence, but because of the statute of limitations. One can only guess how the recent charges and decades of family strife have affected his ability to reason rationally and to remain objective while defending his unpopular theories.

With how complicated they have designed the landing, I sincerely hope it makes it. Whatever happened to simplicity? After the botched Russian mission, one would hope that they get this right.
