The NASA Ares Projects Office is developing the launch vehicles tomove the United States and humanity beyond low earth orbit
Ares I is a crewed vehicle, and Ares V is a heavy lift vehicle beingdesigned to launch cargo into LEO and transfer cargo and crews to theMoon
♦ This is a snapshot of development. Ares V is early in the requirementsformulation stage of development pending a planned authority toproceed (ATP) from NASA in late 2010.
♦ The Ares V vehicle will be considered a national asset, opening newworlds and creating unmatched opportunities for human exploration,science, national security, and space business
♦ My goal today is to update you on the status of the Ares V vehicle

Conclusions
♦ Ares V current concept (51.00.48) exceeds Saturn V mass capability totrans lunar injection by almost 40% alone or almost 60% with Ares I
♦ This concept vehicle can meet current Human Lunar Returnrequirements with ~6 mT of Margin
♦ 2009 activities focused on refining vehicle and operational concept,refining requirements, working with potential non-Constellation usersto understand vehicle/payload benefits and design issues
♦ Ares V is sensitive to loiter time, attitude, power, and altituderequirements, in addition to payload performance
