NASA launched the Ares I-X rocket on October 28, 2009 in a test of the new rocket system. The two-minute suborbital flight encountered some issues, including damage to the launch pad and an unsuccessful stage separation. While the rocket produced over 2.9 million pounds of thrust at liftoff, the test flight highlighted challenges for the Constellation program, which aims to return astronauts to the moon but is facing budget pressures.
