What;s the 'methane venting' going on at the moment ?

What do they use the methane for ?
Fuel (sucking eggs answer) and as it is chilled, pre-cooling the plumbing and I think some engine parts.

Chosen as it is relatively easy to manufacture on Mars (typically described as In-situ resource utilisation).

They’ll say quarter past and then it’ll go up at 8!

What is everyone’s preferred YT channel by the way?

I use NASA Spaceflight right up til the SpaceX feed goes live (subscribe to the channel) then I put SpaceX on the big screen and NSF onto a tablet.

That’s a bit of a bummer - out of balance Raptor.

Surely it takes at least a month and a half to have another go? Or is that only Boeings?

The starship shibboleth is "fully and rapidly reusable"; course, they are supposed to move in the meantime.

While we wait, here is a video of the space shuttle aborting launch at T-1.9 seconds with all 3 main engines already running at nearly 100% thrust. Scary when you think that the solid rocket boosters are 1.9 seconds away from being ignited, and they cannot be stopped once lit. Of course this was all automatic, and the command to ignite the solid rocket boosters is not given by the flight computer until everything else in the countdown checks out.

Because the main engines on the Shuttle were mounted at an angle, if there was a pad abort like this, the whole stack rocked backwards and forwards for a few minutes.

Also, that delayed Delta launch was carrying one of the most complex and expensive spacecraft ever built, for a very sensitive government customer, so they are beholden to be extra cautious. See https://www.thespacereview.com/article/1268/1 for when previous flight of an older payload went wrong.

Ultimately if Elon blows something up today it’s all on him.
