Mars Science Lab launch delayed two years

WASHINGTON (CNN) — NASA’s launch of the Mars Science Laboratory — hampered by technical difficulties and value overruns — has been delayed till the autumn of 2011, NASA officers stated at a information convention Thursday in Washington.

The mission had been scheduled for launch within the fall of 2009.

The Mars Science Lab is a big, nuclear-powered rover designed to traverse lengthy distances with a collection of onboard scientific devices aboard.

It’s, in line with NASA’s Website online, a part of a “long-term effort of robotic exploration” established to “examine the early environmental historical past of Mars” and assess whether or not Mars has ever been — or nonetheless is — in a position to maintain life.

The delay of the launch, in line with NASA, is because of various “testing and {hardware} challenges that should (nonetheless) be addressed to make sure mission success.”

“The progress in current weeks has not come quick sufficient on fixing technical challenges and pulling {hardware} collectively,” stated Charles Elachi, director of NASA’s Jet Propulsion Laboratory in Pasadena, California.

Altering to a 2011 launch “will enable for cautious decision of any remaining technical issues, correct and thorough testing, and keep away from a mad sprint to launch,” argued NASA Affiliate Administrator Ed Weiler.

The general value of the Mars Science Lab is now projected to be roughly $2.1 billion, in line with NASA spokesman Dwayne Browne. The undertaking initially carried a price ticket of $1.6 billion.

NASA’s total price range for the present fiscal 12 months, in line with Browne, is roughly $15 billion.

In response to NASA, the Mars rover will use new applied sciences and be engineered to discover higher distances over rougher terrain than earlier missions to the planet. This will probably be finished partially by using a brand new floor propulsion system.

“Failure shouldn’t be an possibility on this mission,” Weiler stated. “The science is just too essential and the funding of American taxpayer {dollars} compels us to be completely sure that we’ve finished every part attainable to make sure the success of this flagship planetary mission.”

Weiler asserted that, primarily based on the company’s preliminary evaluations, extra prices tied to the delay of the Science Lab launch wouldn’t outcome within the cancellation of different NASA packages over the following two years. He did, nevertheless, concede that it might end in different unspecified program delays.

Critics have charged that the delay and value overruns related to the Mars Science Lab are indicative of an company that’s affected by a scarcity of accountability and inefficiency by way of its administration of each time and taxpayer {dollars}.

“The Mars Science Laboratory is just the newest symptom of a NASA tradition that has misplaced management of spending,” wrote Alan Stern, a former NASA affiliate administrator, in a November 24 op-ed within the New York Occasions. “A most cancers is overtaking our house company: the routine acquiescence to immense value will increase in tasks.”

Stern charged that the company’s value overruns are being fueled by “managers who disguise the dimensions of value will increase that missions incur” and “members of Congress who settle for steep will increase to guard native jobs.”

Browne replied in a written assertion saying that NASA directors are “always working to enhance (the company’s) cost-estimating capabilities. … We regularly assessment our tasks to know the true threat by way of efficiency, value and schedule.”

“The very fact of life at NASA, the place we’re charged with creating first-of-a-kind missions of scientific discovery, is that estimating the prices of … science may be virtually as troublesome as really doing the science,” Browne stated.

NASA’s most up-to-date Mars undertaking — the mission of the Phoenix Mars Lander — got here to an finish final month after the solar-powered automobile’s batteries ran down as the results of a mud storm and the onset of Martian winter. It had operated two months past its preliminary three-month mission.

NASA officers had landed the automobile on an arctic plain after satellite tv for pc observations indicated there have been huge portions of frozen water in that space, almost definitely within the type of permafrost. They thought such a location can be a promising place to search for natural chemical substances that may sign a liveable setting.

Scientists have been in a position to confirm the presence of water-ice within the Martian subsurface, discover small concentrations of salts that might be vitamins for all times, and observe snow descending from the clouds, NASA stated Thursday.
