NASA Official Defends Ares I Work, Says Program on Track

Steve Cook, manager of NASA’s lunar Ares program, says critics are wrong about the Ares I launcher being underpowered, poorly designed and behind schedule, according to a article. Speaking during a recent conference in Denver, Cook said the vehicle has acceptable payload margins and that NASA engineers have oscillation and control issues well in hand.

“We have hit all our milestones and are on track to hit [the preliminary design review] milestone in August 2008. We won’t go into a review unless we’re ready,” Cook said.
