Abort.

2 big space fails today..!

Hopefully this isn't supposed to save us from ISON

Aww those poor people, working today and all.

They may recycle and try again after looking at the data. The launch window is 66 minutes starting at 5:39 EST

Yes!

Let us hope, update the title if we go back to count down.

I'll check in

They recycled and launched on one previous flight but it was a Falcon 1 rocket. They adjusted computer parameters and launched the 2nd time. Hopefully they can do that again tonight.

updated title will do it again with new T-0 when they announce it.

last second abort?

They just said that it was 1 second from liftoff when the computer aborted. That was close.

they are going to try again..

Launch aborted by autosequence due to slower than expected thrust ramp. Seems ok on closer inspection. Cycling countdown.

The rocket does a self test just before lift-off. If it finds something out of tolerance the computer aborts the launch. Since this is only the 2nd launch of the Falcon 9 Version 1.1 they are still learning where things are suppose to be. They will adjust the thrust ramp up tolerance and try again.

here is the first attempt with abort.

Launch window closes at 6:44 pm EST

New launch T-0 at 6:44 the very end of window. Will update the tread title

Let's see if they pull this one off.

Launch now targeting 6:44pm ET. [link to www.spacex.com]

Customer just informed SpaceX they could extend the launch window another 20 minutes. Puts window to 7:04 EST. Never seen that before.

Customer said extend the window is necessary by 20 min.

7:04 is the new window if needed.

SpaceX always has drama on launch day. They are fun to watch.

Go for launch 6:44 pm

Increasing helium spin start pressure. Probably <50% chance of passing all aborts, but worth a try. Countdown resuming ...

T-5 minutes. strong-back retracting
