WASHINGTON -- NASA administrator Sean O'Keefe said Wednesday the cost of fixing all that ails the space shuttle fleet could top $2.2 billion - double the estimated price tag given to Congress a year ago.
O'Keefe, testifying before the Senate Commerce Committee, was pressed on whether that estimate again could rise.
Sen. Sam Brownback, R-Kan., who chaired the panel, noted that the space agency still had 10 items left on 15 required improvements it must complete before shuttles again can fly. Brownback asked O'Keefe whether the agency had confidence in the higher estimate.
"We're getting a lot closer, that's for sure," O'Keefe said. "I don't see any new unknowns coming down the road."
Thomas P. Stafford, co-chair of a task force monitoring the space agency's progress in meeting the new safety requirements, said he expected NASA would earn at least conditional approval on the remaining 10 items by the end of 2004.
The space shuttle fleet has been grounded since Feb. 1, 2003, when the shuttle Columbia broke apart over Texas, killing all seven astronauts.
O'Keefe said it wasn't clear whether damage to Kennedy Space Center from Hurricane Frances would result in a delay of the anticipated spring 2005 launch of Discovery. NASA disaster response teams are completing an inventory of damaged facilities.
Flipping through oversized, color images, NASA officials pointed to roughly 1,000 missing panels from an Apollo-era hangar where pre-launch assembly of shuttles should occur. Each missing aluminum panel represents an open window through which damaging wind and rains from Hurricane Ivan, the next brewing storm, could pass, said Sen. Bill Nelson, D-Fla.
Nelson counseled O'Keefe to be speedy with the agency's repair estimate and to include the cost of building a structure that could withstand higher-force winds. The damaged building was designed to withstand gusts up to 125 mph, while a direct blow by a category 4 hurricane could yield 145 mph winds.
The damage, Nelson said, underscored the folly of the space agency's raiding its maintenance budget to make up for federal funding that hasn't kept pace with its needs.
"NASA has been robbing Peter to pay Paul because NASA has not had the increases that it has needed to do an ambitious space program," Nelson said. "And you can't do space flight on the cheap."
