Third SpaceX Falcon 1 Launch Fails
The third SpaceX Falcon 1 rocket failed shortly after lifting off from Omelek Island, Kwajalein Atoll, on August 3, 2008. Liftoff of the 21.3 meter tall, 27.67 tonne, two stage rocket occurred at 03:34 UTC. According to a message from Elon Musk to NasaSpaceFlight.com, the failure occurred at staging, about 2 minutes 39 seconds after liftoff, following a nominal first stage burn. A video feed of the launch provided by SpaceX was cut off about 2 minutes 11 seconds after launch, shortly before second stage pressurization, first stage cutoff, and stage separation would have occurred.
Lost with the Falcon 1 were the U.S. Air Force Jumpstart mission's Trailblazer satellite, NASA's Nanosail-D solar sail experiment, and NASA's PreSat experiment. Total payload mass was 170 kg. The payloads were expected to be boosted into a 685 x 330 km x 9 deg orbit.
It was the third Falcon 1 failure in three attempts.
A regeneratively cooled Merlin 1C engine flew for the first time on the flight, boosting Falcon 1 off its pad and downrange for most, if not all, of its planned 2 minute 38 second burn. The engine had aborted an initial countdown attempt 34 minutes before the launch, shutting down during its start sequence when one measured parameter was detected to be out of limit. SpaceX crews recycled the count in 23 minutes.Third SpaceX Falcon 1 Launch Fails

看来级间分离是个大问题,两次都出在这个问题上,都所出的问题却不一样。不过联系7月29号和8月1号Falcon 9第一级的两次点火成功说明Merlin 1C确实相当成熟。只要把级间分离的问题解决SpaceX还是很有前途的。
