Apparently SpaceX had a computer timing glitch that caused an unnecessary abort yesterday. Launch is back on for 7 PM Eastern.

[Update at 6:25 PM EDT]

The launch is apparently still on, but no webcast yet.

[Update at 7:04 PM EDT]

It’s about an hour before the new schedule for the launch. 8:05 PM EDT. Webcast still hasn’t started, with no explanation as to why.

[Update after schedule launch time]

Wow. Aborted after engine start?

That’s a new one.

But Clark says that there still may be a launch tonight.

[Update at 9:30 EDT]

So far the launch seems succesful.

[Another update]

Complete success seems uncertain at this point, but it’s a huge improvement over the last attempt.

We’ll know more on the morrow. Too late to evaluate for us East Coasters.

More thoughts tomorrow, with more information.
