Memo Marks Formal End of Constellation Program

摘要

A senior NASA official has signed the formal death warrant for the Constellation deep space exploration program even as work proceeds on one of Constellation's legacy development efforts and agency officials continue to ponder the fate of another. "I have signed the letter to close out the Constellation Program," Douglas Cooke, associate administrator for NASA's Exploration Systems Mission Directorate, wrote in a June 10 memo.
