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 a Spaceflight Now article was posted a couple of days with some information I hadn't seen before, which they got from a phone interview with Elon Musk:
http://www.spaceflightnow.com/news/n0909/24falcon/ The dragon capsule for Flight #1 will end up in a circular orbit 155 miles up, but won't have engines to maneuver itself. Nevertheless, it'll carry a payload of some sort for an unidentified customer. SpaceX has actually requested a November 29 launch date, but Musk says that'll only happen if everything goes according to plan. He said that on the last two Falcon 1 flights everything actually DID go according to plan, but, of course, this is a brand new rocket. It agrees with UGordan that Flight #2 won't even try to get close to the ISS, and #3 will approach but not try to dock. It implies that #4 WILL try to dock, assuming the other flights went okay. (Apologies if there are any errors in the summary.) UGordan: I really appreciate your corrections, clarifications, and new information -- especially since you seem to have some kind of inside information. :-) Do you know why they're not trying harder to recover and reuse the rockets? They've made a big deal in their printed materials about how important that is. --Greg |
