WASHINGTON (CNN) — NASA’s launch of the Mars Science Laboratory — hampered by technological issues and expense overruns — has been delayed until the drop of 2011, NASA officers mentioned at a news meeting Thursday in Washington.

The mission experienced been scheduled for launch in the fall of 2009.

The Mars Science Lab is a large, nuclear-run rover developed to traverse extended distances with a suite of onboard scientific instruments aboard.

It is, in accordance to NASA’s Net website, part of a “prolonged-expression work of robotic exploration” established to “research the early environmental history of Mars” and assess no matter whether Mars has at any time been — or even now is — able to sustain lifestyle.

The hold off of the launch, according to NASA, is owing to a amount of “screening and components challenges that need to (even now) be addressed to guarantee mission accomplishment.”

“The development in current months has not occur rapidly sufficient on resolving complex problems and pulling hardware collectively,” stated Charles Elachi, director of NASA’s Jet Propulsion Laboratory in Pasadena, California.

Modifying to a 2011 start “will allow for cautious resolution of any remaining specialized difficulties, correct and thorough tests, and stay away from a mad sprint to launch,” argued NASA Associate Administrator Ed Weiler.

Don’t Overlook

The all round cost of the Mars Science Lab is now projected to be around $ two.1 billion, in accordance to NASA spokesman Dwayne Browne. The task initially carried a price tag tag of $ 1.6 billion.

NASA’s whole spending budget for the existing fiscal 12 months, according to Browne, is about $ fifteen billion.

According to NASA, the Mars rover will use new technologies and be engineered to investigate better distances more than rougher terrain than preceding missions to the planet. This will be done in portion by using a new area propulsion system.

“Failure is not an option on this mission,” Weiler mentioned. “The science is too important and the expense of American taxpayer pounds compels us to be totally specific that we have done everything attainable to ensure the accomplishment of this flagship planetary mission.”

Weiler asserted that, based on the agency’s preliminary evaluations, added costs tied to the delay of the Science Lab start would not outcome in the cancellation of other NASA packages more than the next two years. He did, nevertheless, concede that it would result in other unspecified software delays.

Critics have billed that the delay and price overruns linked with the Mars Science Lab are indicative of an agency that is plagued by a absence of accountability and inefficiency in phrases of its management of both time and taxpayer bucks.

“The Mars Science Laboratory is only the newest symptom of a NASA tradition that has lost control of paying,” wrote Alan Stern, a previous NASA affiliate administrator, in a November 24 op-ed in the New York Times. “A most cancers is overtaking our area agency: the regimen acquiescence to enormous expense raises in tasks.”

Stern billed that the agency’s cost overruns are being fueled by “professionals who disguise the measurement of cost increases that missions incur” and “users of Congress who settle for steep raises to protect nearby employment.”

Browne replied in a written statement stating that NASA administrators are “consistently operating to enhance (the agency’s) cost-estimating capabilities. … We continuously assessment our tasks to comprehend the correct threat in terms of performance, cost and plan.”

“The reality of existence at NASA, in which we are billed with producing first-of-a-variety missions of scientific discovery, is that estimating the fees of … science can be practically as difficult as in fact doing the science,” Browne stated.

NASA’s most recent Mars undertaking — the mission of the Phoenix Mars Lander — came 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 winter season. It had operated two months over and above its initial three-month mission.

NASA officials had landed the vehicle on an arctic plain soon after satellite observations indicated there ended up large quantities of frozen drinking water in that region, most probably in the type of permafrost. They considered this kind of a spot would be a promising location to search for natural and organic substances that would signal a habitable environment.

Scientists have been capable to confirm the existence of h2o-ice in the Martian subsurface, discover small concentrations of salts that could be vitamins and minerals for daily life, and observe snow descending from the clouds, NASA stated Thursday.
