June 13, 2009-- Look for some potential "wheeling and dealing" at NASA over the Endeavour fuel leak. It could take four days to fix, which one day past the agency's deadline to launch before letting an Atlas rocket go next to carry a unmanned mapping probe to the Moon. NASA could negotiate Endeavour to the front of the line beyond Monday, but that might cause problems for other people. There are a number of Atlas missions waiting to go, and making the Moon probe wait means other Atlas missions would likely be delayed as well.
