NASA OIG: Review of NASA's Acquisition of Commercial Launch Services

"We found that NASA's LSP acquired ELVs from 2008 through 2009 that were within costs and timeframes established by the NLS contracts. However, we also found that NASA's published strategy for acquiring medium-class launch vehicles after 2010 may not be the most cost-effective or advantageous to the Government because it did not include as a possible option use of Minotaur, a launch vehicle that uses a U.S. Government-furnished rocket motor from decommissioned intercontinental ballistic missiles."
