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. |

Now, my understanding is that this particular Falcon 9 that is being assembled contains "many" flight systems but also contains some non-flight components, and will never fly as a unit. That it's rather like the 500-F version of the Saturn V, that was stacked and rolled out to the pad as a test vehicle to validate the procedures needed to get the bird ready to fly.
So, before a Falcon 9 actually flies, the article we're seeing right now will need to be taken apart and a full flight vehicle will need to be assembled. Correct? Ergo, it's not like we're on the verge of seeing this bird take to the skies... and in fact, this particular bird never will, in its present configuration. So I wouldn't worry about it flying before they have a chance to get a couple more Falcon 1 successes under their belts. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

So, before a Falcon 9 actually flies, the article we're seeing right now will need to be taken apart and a full flight vehicle will need to be assembled. Correct? Correct, this vehicle is not the exact maiden flight vehicle, but it does contain the majority of actual flight hardware that'll see flight. It's unclear what exactly components will be replaced for the flight, in this regard it's not like SA-500F in that this one will not be shelved and discarded, but the majority of what you see here is actually bound to fly. Elon can't afford building too many non-flight items just for this purpose if he wants to get this bird off the ground and start making profit. The non-flight ready (perhaps qualification components) will for the time being be used for pathfinding activities at the pad, once the hangar is built it will be destacked and the remaining non-flight components will be replaced with flight units. It's possible the 1st stage engines will be replaced since these are the ones that disturbed Texans for 3 minutes in November. The 2nd stage engine is missing the huge nozzle extension (not visible inside the interstage) and probably none of the avionics are installed yet. The 2nd stage might be a qualification unit altogether. So I wouldn't worry about it flying before they have a chance to get a couple more Falcon 1 successes under their belts. As I said above, the launch manifest calls for just one Falcon 1 launch before the maiden Falcon 9 flight is scheduled. There's a total of 2 F1s manifested in 2009 so unless F9 is seriously delayed, that'll be it. For comparison, there are 5 (!) F9 flights scheduled for this year. -------------------- |

That sounds ambitious; I hope they can do it. |
