WASHINGTON (CNN) — NASA’s launch of the Mars Science Laboratory — hampered by technological issues and expense overruns — has been delayed right up until the tumble of 2011, NASA officials said at a information convention Thursday in Washington.

The mission had been scheduled for start in the tumble of 2009.
The Mars Science Lab is a large, nuclear-powered rover made to traverse very long distances with a suite of onboard scientific instruments aboard.
It is, in accordance to NASA’s Web web page, part of a “extended-phrase hard work of robotic exploration” established to “research the early environmental historical past of Mars” and evaluate no matter if Mars has at any time been — or nonetheless is — capable to sustain life.
The delay of the launch, in accordance to NASA, is owing to a variety of “tests and components problems that must (even now) be addressed to guarantee mission good results.”
“The development in current months has not appear rapidly ample on resolving specialized worries and pulling components alongside one another,” said Charles Elachi, director of NASA’s Jet Propulsion Laboratory in Pasadena, California.
Shifting to a 2011 start “will enable for mindful resolution of any remaining specialized difficulties, good and complete screening, and stay away from a mad sprint to launch,” argued NASA Affiliate Administrator Ed Weiler.
The all round price tag of the Mars Science Lab is now projected to be about $2.1 billion, in accordance to NASA spokesman Dwayne Browne. The undertaking at first carried a price tag tag of $1.6 billion.
NASA’s full spending budget for the latest fiscal calendar year, in accordance to Browne, is somewhere around $15 billion.
In accordance to NASA, the Mars rover will use new technologies and be engineered to investigate better distances in excess of rougher terrain than previous missions to the planet. This will be performed in aspect by using a new area propulsion process.
“Failure is not an option on this mission,” Weiler reported. “The science is too vital and the financial commitment of American taxpayer dollars compels us to be certainly specific that we have accomplished everything attainable to make certain the achievements of this flagship planetary mission.”
Weiler asserted that, primarily based on the agency’s preliminary evaluations, extra costs tied to the delay of the Science Lab launch would not result in the cancellation of other NASA plans more than the subsequent two decades. He did, having said that, concede that it would outcome in other unspecified plan delays.
Critics have charged that the delay and value overruns related with the Mars Science Lab are indicative of an agency that is plagued by a lack of accountability and inefficiency in conditions of its administration of both of those time and taxpayer dollars.
“The Mars Science Laboratory is only the hottest symptom of a NASA lifestyle that has lost handle of paying out,” wrote Alan Stern, a former NASA affiliate administrator, in a November 24 op-ed in the New York Instances. “A most cancers is overtaking our area agency: the program acquiescence to huge price raises in initiatives.”
Stern charged that the agency’s cost overruns are remaining fueled by “managers who disguise the dimensions of cost raises that missions incur” and “associates of Congress who settle for steep boosts to shield regional employment.”
Browne replied in a written assertion expressing that NASA directors are “continually functioning to enhance (the agency’s) expense-estimating abilities. … We continually evaluation our initiatives to have an understanding of the genuine hazard in conditions of general performance, price and program.”
“The reality of existence at NASA, exactly where we are billed with making first-of-a-type missions of scientific discovery, is that estimating the fees of … science can be pretty much as tough as essentially carrying out the science,” Browne explained.
NASA’s most modern Mars job — the mission of the Phoenix Mars Lander — arrived to an conclude very last thirty day period right after the solar-powered vehicle’s batteries ran down as the consequence of a dust storm and the onset of Martian wintertime. It had operated two months over and above its initial a few-month mission.
NASA officers experienced landed the automobile on an arctic plain immediately after satellite observations indicated there had been large quantities of frozen drinking water in that spot, most possible in the sort of permafrost. They imagined this sort of a place would be a promising area to look for natural and organic chemical compounds that would signal a habitable natural environment.
Researchers had been in a position to confirm the existence of h2o-ice in the Martian subsurface, uncover compact concentrations of salts that could be vitamins for everyday living, and notice snow descending from the clouds, NASA reported Thursday.
