With the launch of the first Orion space vehicle in a few hours time, I thought that it deserved a thread with a title that showed that the programme had progressed quite a bit since the original Orion thread was posted up.

If mods want to close this thread that's fine but I think the original title is not really immediate enough for today's events.

Launch is scheduled for 12.05 pm (just after mid-day) UK time.

I'm getting quite excited by this.

Thanks for the alternative link. Spaceflight now seems to have gone off the air for the moment.

just said T-6 minutes so looks like it's going before midday...

ETA, wrong, that was 6 minutes to go until 15 minutes to go.

Over 200 feet tall so 2/3 the height of a Saturn V. The Shuttle was about 100 feet tall.

The Delta IV Heavy develops 2 million pounds of thrust on lift off.

For comparison, the Shuttle was 6 million pounds and the Saturn V was 7.5 million pounds. The Saturn 1B was 1.5 million pounds.

Is that Saturn V thrust figure just the launch stage?

Yes - the five F1 engines pumped out 1.5 million pounds of thrust each. They ran on kerosene and liquid oxygen.

To put that in context, each F1 engine delivered the same thrust as the THREE main engines of the Space Shuttle

When is the projected launch date for a manned mission? I seem to remember 2030 or so...
