NASA's Orion powered on for the first time

[Eric Mc]

Ignore said retards.

[funkyrobot]

Still there. New launch time?

I'm sneakily watching at work with no sound.

They are discussing it at the moment. They say it good to go, but lock pins installed.

Does the apprentice have to wander down and take them out?

Waiting for a review of the forecast winds.

I thought they used what the Saturn used but the shuttle was pins I believe (big pins!) One use, they pulled out I think?

Edit 2. Not sure I have the right bits in mind

Edit 3. Think I am misunderstanding what the lock pins are.

At the moment of ignition, put the sound up to "full" and scare the bejaysus out of everybody

That would be great.

It would lose its appeal when they send me home and tell me to not bother coming back though.

gahhhh. hold.

wow, check out the service module mass of Orion compared to Apollo!



Wonder where that enormous mass reduction comes from?

How can SM maximum thrust be a third of the Apollo SM if it is due to operate in similar environments/escape from the gravity of similar or larger celestial bodies as Apollo? Or will this misson-specific and will be ramped up in due course?

Isn't a third of the weight too? so only needs a third of the trust for the same power to weight ratio.

[Eric Mc]

And as has already been mentioned, the SPS of the Apollo spacecraft was really too powerful for the job it ended up doing.

[funkyrobot]

Is this launch canned now?

Sorry, keep dipping in and out of the feed.

Apologies on both counts - both absolutely right. Having a bit of a duh-day today...

Still some time left in the launch window - but it is running out.

Thanks.

Have had to keep the feed on mute here so no idea what they are saying, though I do know that the launch window is open until 14:44 GMT.
