instruments that were cast off
NASA’s Mars Science Laboratory
�for being over budget have earned their way back onto the mission
, which is scheduled for an August 2009 launch, according to the U.S. space agency’s science chief.
NASA announced in September that it was scaling back some of Mars Science Laboratory’s capabilities in order to keep the $1.7 billion rover mission on track.
writing another $75 million check for the already over-budget mission, NASA scuttled
a descent camera designed to capture color video of the
approaching martian surface and refused
to provide any money beyond 2007 for Chem-Cam, a laser instrument that has exceeded its budget by 70 percent.
But Alan Stern, NASA’s associate administrator for science, told Space News that the
-Cam and the Mars Descent Imager (MARDI) programs have since
found solutions to their budget quandaries and were back on the manifest.
“When Chem-Cam and MARDI figured out that we really meant that MARDI wasn’t going to fly and Chem-Cam wasn’t getting any more money, they came back to us with a way to do it without any significant money from us,” Stern said in an interview.
In the case of MARDI, the camera’s designer and principal investigator, Mike Malin of San Diego-based Malin Space Systems, offered to finish the instrument
at his own expense. NASA plans to pay for
installing MARDI aboard the Mars Science Laboratory
using money it had planned to give Malin to process and analyze imagery from an identical camera launched aboard the Mars Phoenix Lander this summer. Those funds
are no longer needed, Stern said, due to a data-handling problem discovered shortly before launch
�that will limit Phoenix to taking just one picture with the camera.
“The combination of him finishing on his own dime and giving back the Phoenix money ended up costing us nothing for flying MARDI, so of course we will do it,” Stern said.
The Chem-Cam team, led by the Los Alamos National Laboratory in New Mexico, also dug deep to solve its budget problems. The
instrument emerged from the Mars Science Laboratory
‘s critical design review more than 70 percent over budget and still in need of $2.5 million to finish
�development and $1.3 million
for integration with the rover.
Stern pledged to
find the money for integration if the team could figure
a way to finish the Chem-Cam without extra funding
The Chem-Cam team solved $1.5 million of its budget problem through increased contributions from its French colleagues and by simplifying its work plan –
Stern described it as “separating the icing from the cake in terms of the work to go.”
The director of Los Alamos
, meanwhile, agreed to back his principal investigator with about $600,000
. “This left an unfunded amount of about $400,000,” Stern said. “I declared victory. We had succeeded in eliminating over 80 percent of the problem.”
Stern said he plans to cover the cost of Chem-Cam’s integration out of some $2 million NASA’s Science Mission Directorate saved by getting Phoenix off at the very start of its three-week launch window.
