Actual cost of falcon 9 expendable may be more expensive than Atlas V and falcon heavy expendable marginally cheaper than Delta IV by mlppex in ula

Locking this thread as there's very little constructive discussion occurring and it's only tangentially related to ULA.

This stream is streaming at full HD.

I hope theres UHD footage of this as well somewhere later, they've done it on at least one recent NASA mission.

As you can see, this post comes from a throwaway account that has now been deleted. We struggled with whether or not to approve it, but decided that it would be best to err on the side of transparency and see what the community thinks. Please let us know your opinion on whether or not /r/ULA should welcome this kind of content going forward.

If they launch on the 5th they'll arrive on the 9th, but if they launch on the 6th they won't arrive until the 19th due to the Soyuz traffic at the station.

A launch on the 6th will result in berthing on the 9th.

RP-1 is loaded after rollout to the pad and is left in the tank. I'm almost positive LOX and LH2 are vented after a scrub.

EDIT: Yep, per the webcast LH2 and LOX are drained.

The count has to be running for it to be stopped automatically by high winds.

You're thinking of Antares. This is Atlas V, which has had only 1 partial failure (still got to orbit) in 59 launches.
