Keith Cowing gets it wrong on ARES I
Someome posted a link to a cowing site a couple weeks ago with a story that Ares1 won't have adequte thrust for a lunar CEV mission. NASA has nixed this rumor.
NASA says the Ares I "provides a 15% margin of performance in addition to the energy needed to put the fully crewed and supplied Orion into orbit for a lunar mission".
