NASA's Cheaper Mars Rover Is Now Very Expensive

NASA's Management of the Mars Science Laboratory Project, NASA OIG, 8 June 2011

"... in February 2009, because of the late delivery of several critical components and instruments, NASA delayed the launch to a date between October and December 2011. This delay and the additional resources required to resolve the underlying technical issues increased the Project's development costs by 86 percent, from $969 million to the current $1.8 billion, and its life-cycle costs by 56 percent, from $1.6 billion to the current $2.5 billion. ... Finally, since the 2009 decision to delay launch, the Project has received three budget increases, most recently an infusion of $71 million in December 2010. However, in our judgment because Project managers did not adequately consider historical cost trends when estimating the amount required to complete development, we believe the Project may require additional funds to meet the 2011 scheduled launch date."

"The new rover announced Tuesday, along with the rocket needed to boost it to Mars, will cost somewhere in the neighborhood of $1.5 billion, plus or minus $200 million, according to a rough estimate by the Aerospace Corp."

"[George] Tahu said that the mission also decided to add new technologies to the rover, including a system that increases the accuracy of the rover's landing and another to improve the rover's ability to drive autonomously. "Our confirmed cost today, in real year dollars, of $2.1 billion for development and launch and $300 million for prime mission operations remains consistent with the scope and cost approved at the start of the project," he said."

Keith's note: So that's $2.4 billion for a rover that was supposed to cost around $1.5 billion - a rover that was sold as being inherently cheaper because it was made with MSL spare part, lessons learned from MSL mistakes, etc. Once again JPL has ignored NASA's price claims - and NASA SMD just can't fight the urge and lets it happen. Can you imagine what will happen when NASA starts to price the whole #JourneyToMars thing?
