On Aug 31, 2012 SpaceX conducted a full wet dress rehearsal (WDR) for its scheduled Oct 8 2012 08:12 PM EST launch of SPX-1, its first fully operational cargo Dragon resupply mission to the ISS.

In a WDR the Falcon 9 is rolled out, fueled and the countdown run down to the very moment before engine ignition. Then the tanks are drained, the F9 is rolled back to the hangar and everything is checked out. Later another rehearsal will include a "hot-fire" - a 3-4 second engine burn to check them out too. This usually tales place a few days before launch. During the recent WDR the Dragon and its cargo trunk were not attached, but they likely will be for the hot-fire.

Non-ISS cargo for this flight will include a prototype ORBCOMM OG2 communications satellite built by Sierra Nevada Corp. (also builders of the Dream Chaser spaceplane.) If all goes well 17 more ORBCOMM's will be lofted on later F9 flights.

This will be the next to last flight for the Falcon 9 v1.0 before the much larger and powerful Falcon 9 v1.1 comes into service. The F9 v1.1 will also be the core stage of the monster Falcon Heavy.

[quote][b]SpaceX tests rocket engines on pad[/b]

SpaceX says it successfully test-fired the engines on its Falcon 9 rocket today in preparation for Oct. 7's scheduled liftoff of the California-based company's first official cargo delivery to the International Space Station.

The static-fire test at Cape Canaveral Air Force Station in Florida was considered the "last major test" in advance of the launch, SpaceX said in a Twitter update. The rocket was held down while its nine Merlin engines blazed for a couple of seconds on the pad, at the end of a computer-controlled fueling sequence. Data from the test will be analyzed in advance of the scheduled launch at 8:34 p.m. ET on Oct. 7.[/quote]

nice patch and a historical moment, now it's no more practice...it's the actual thing! we are at the threshold of a new phase in space exploration and settlement. next stop Pandora, i mean Mars!

good luck to the mission and thank you to all the talented people that make us proud to be human.

Remember that this is the next to last flightfor Falcon 9 v1.0.

After the next flight (CRS-2 / SPX-2) the next launch will be from Vandenberg AFB using the upgraded Falcon 9 v1.1 - a much larger (229' v 157') and more powerful beast. The engine mounting is also changed from a 3x3 grid to an octagon with a center engine.

Launch: perfect

Flight to orbit: perfect

Dragon is in orbit, her solar wings are deployed and arrival at ISS is scheduled for Wednesday morning.

Unfinished business: 2nd stage is to re-fire to put an Orbcomm communications satellite into its geosynchronous transfer orbit.

Update:

With most all rockets if an engine fails the range safety officer blows it up as there isn't enough power remaining to continue the launch. End of mission, everything is lost.

An engine-out capability prevents this.

NASA had engine-out capability with the 5 engine Saturn V moon rocket, but not since. SpaceX has picked up that ball and is running with it because F9's engine-out capability has been proven during this launch.

At about 01:20 into the flight there was an anomaly on engine #1 as F9 entered a cloud bank. Speculation is that engine 1's turbopump, which delivers the fuel & oxidizer, blew out spewing debris.

F9 is designed with armor plate and ballistic blankets (Kevlar) around each engine to catch the debris from such an events, so the F9's computer just shut down that engines fuel and oxidizer valves then burned the others a bit longer. Problem solved.

Result: the Dragon and Orbcomm satellite are now in their proper orbits in spite of an engine failure.

This engine-out capability makes Falcon 9 a very safe rocket.

"Falcon 9 detected an anomaly on one of the nine engines and shut it down," Musk wrote in an email... "As designed, the flight computer then recomputed a new ascent profile in realtime to reach the target orbit, which is why the burn times were a bit longer." [/quote]

Slow motion video of the event. Watch the top-right engine and you'll see the flameout and possible RUD ("rapid unscheduled disassembly" - an Elon Musk-ism.)

Remember: with any other US (and AFAIK foreign) launcher since Saturn V this would cause the flight termination (abort) system to destroy the rocket. Not so with Falcon 9.

Full Elon Musk statement -

[quote]Falcon 9 detected an anomaly on one of the nine engines and shut it down. As designed, the flight computer then recomputed a new ascent profile in realtime to reach the target orbit, which is why the burn times were a bit longer. Like Saturn V, which experienced engine loss on two flights, the Falcon 9 is designed to handle an engine flameout and still complete its mission. I believe F9 is the only rocket flying today that, like a modern airliner, is capable of completing a flight successfully even after losing an engine. There was no effect on Dragon or the Space Station resupply mission.[/quote]
