At NASA's third space exploration conference on 26 February in Denver, Ares programme manager Steve Cook spoke about what he called "myths" about Ares 1 performance problems.
Ares had a 2,200kg (4,400lb) performance margin over and above the lunar
mission's requirement and 1,360kg performance margin over Orion's maximum mass needs that the oscillation issue was well known and would be solved and that
after 4,200h of wind tunnel tests and the availability of heritage thrust vector
control technology Ares I would be controllable in flight.
