Skip to comments.Space X Launch Live Now on NASA TV (Scrubbed @T-0.5 seconds in Ignition Sequence/Presser@6:30AM EDT)

It's also on Space X.com
1:55 AM Pacific Time
4:55 AM Eastern TIme
Space Station is flying over Florida and this is now T-10 minutes at Falcon Launch Control
Thanks for the heads up!
Does this one have any real cargo, or is it going empty?
Computer is non starter.
Vehicle is being safed.
The framing cut away.
Ignition sequence started but there was a cut-off
This one is unmanned but contains cargo that will be unloaded once it docks. After undocking it will return to earth. This is the final test flight, so future launches will probably have passengers, 7 of them in each flight, similar to the space shuttle.
Got it. Aren’t they also doing testing with this flight to test docking aborts and other proceedures?
I wouldn’t know. I assume they’d test as much as they could, as long as they’re going through the whole docking procedure.
You’re welcome, Aquila. Wish it had taken off but good to know that computer picked up an error in sequence and stopped it.
You’re welcome, Cementjungle. I had both NASA TV and Space X webcast windows open.
Yes, it’s a disappointment. Better safe than sorry though.
Thanks for adding in more info. :)
“mission scrubbed”..........oh, the good old days.
NASA News Conference on now.
Q: Marcia Dennis AP: When did clock stop?
A: t-.5 seconds
Q: Were all 9 engines firing?
A: Engine 5 was firing too high
Audio is weird, fading in and out.
Q: How many engines can fail and still achieve success.
A: Need liftoff with all 9, but can get by with only 2 engines once in flight.
Q: How many times have you aborted at this juncture?
A: Flight 1 aborted with over high pressure in engine 5 (same engine)
Q: Is this a failure - how do you react to people who call this a failure?
A: This is not a failure, we aborted with purpose, would have been failure if had proceeded to liftoff
Q: How long to switch out engines?
A: Should be one day, not an expert, but will know more later. Just wanted to give you info we have right now.
Q: Is 23rd launch time 3:21 a.m. and can you tell after launch could you continue with 7 or 8 engines?
A: 22nd 3:43 a.m. 23rd approximately 3:21 a.m. Will get that info to you later
Q: Did all 9 engines have ignition?
A: All engines had ignition then engine 5 trended high pressure
Q: Did it lift off at all?
A: No, we hold it down on purpose... we were revving the engines and decided not to fly.
Q: What sorts of things might cause this high pressure?
A: High pressure caused by high temperature caused by low fuel; have to spend time looking at data
Q: Inspection today - how complicated, is it just a visual
A: Will probably bore scope the pump...
Q: What is the similarity to first Falcon 9, do you have a feeling that it is a valve?
A: on Flight One we had a narrower abort on Flight One...
Q: Were told you would try every 3 days, why now the 23rd as well?
A: We had mentioned 23rd yesterday
Q: Can you still get back in on the 22nd
A: Should be able to, don’t have enough data.
NASA confirms time:
If Launch on 22nd 3:44 a.m. 23rd 3:22 a.m.
I’d rather watch the Saturn 5 launches on youtube(:
Heh, and with much of the optimism of the good old days.
Historical videos found on You Tube can be interesting.
You try to launch a rocket into space..
I would imagine they’ll have to replace/refurbish quite a few components utilized or exhausted because of near launch.
I'm not in the "launch a rocket into space" business.
Do they know exactly what the problem was yet?
Just received this email from SpaceX:
Update on SpaceX COTS 2 Test Launch
May 19, 2012
Todays COTS 2 Demonstration launch was aborted half a second before liftoff when the flight computer detected slightly high pressure in the engine 5 combustion chamber. We have discovered root cause and repairs are underway.
During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine. We are now in the process of replacing the failed valve. Those repairs should be complete tonight. We will continue to review data on Sunday. If things look good, we will be ready to attempt to launch on Tuesday, May 22nd at 3:44 AM Eastern.
The next launch attempt will be webcast live at www.spacex.com.
Thanks for the update, Jack. Did you see the launch yesterday?
Yes, I did stay up to watch it!
