Kind of small; What’s the specs?

[JRandomFreeper]

Absolutely not possible for commercial guys to do that. I've been told that right here on FR. /s

I may nap up and wake up in time for the launch. Power naps are great. And I'm getting better at them, with practice.

Jack Hydrazine checking in...

Think I’ll stay up for this launch. Since I’m on the Left Coast it’ll be a 1:55 a.m. lift off.

How many others are staying up for it?

Update on SpaceX COTS 2 Test Launch

May 19, 2012

Today’s 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.
