SpaceX just sent a press release with an update on the Falcon 9. They successfully did a 5-engine test. They also mentioned the next Falcon 1 attempt will be late June "or July," presumably meaning "late June or early July," but you never know. :-)
Here's the full text. This isn't on their web page yet, the last I looked: McGregor TX – Space Exploration Technologies Corp. (SpaceX) conducted the first five-engine firing of its Falcon 9 medium to heavy lift rocket at its Texas Test Facility outside McGregor on Thursday, May 29. At full power the engines generated almost half a million pounds of force, and consumed 1,750 lbs of fuel and liquid oxygen per second. This five engine test again sets the record as the most powerful test yet on the towering 235-foot tall test stand. The test of the five Merlin 1C engines, arranged in a cross pattern like the Saturn V moon rocket, is the last step before firing the full complement of nine engines, scheduled for this summer. With all engines operating, the Falcon 9 generates over one million pounds of thrust in vacuum - four times the maximum thrust of a 747 aircraft. “This is the first time that we’ve added more than one engine at a time, and all phases of integration and testing went smoothly,” said Tom Mueller, Vice President of Propulsion for SpaceX. “As with previous tests, we saw no unexpected interactions between the engines, and are on schedule for adding four more engines.” The first Falcon 9 will arrive at the SpaceX launch site at Cape Canaveral by the end of 2008. The next flight of SpaceX’s smaller Falcon 1 rocket is scheduled for late June or July of 2008. |

I just noticed that SpaceX has added a document discussing the use of the Falcon 9 to launch payloads to the moon.
http://www.spacex.com/FalconLunarCapabilityGuide.pdf It says they can put 1.925 metric tons into a Trans-lunar Injection orbit for $46.8M. It also mentions (in a graph) putting 1.2 tons into "Mars XFER". I was trying to see how that compares to either Phoenix or MSL, but I can't quite find the equivalent numbers. Anyone have them handy? --Greg |

PHX injected mass was 670 kg, but one always has to be careful about the specifics of the transfer orbit for any given mission, since the C3 to Mars can vary by a factor of 2. You need more information than a single number to assess mission feasibility. MSL injected mass is, according to http://mars.jpl.nasa.gov/msl/mission/spacecraft.html, about 3400 kg. -------------------- Disclaimer: This post is based on public information only.
