Will be surprised if #Artemis1 launch happens today. If or when today's countdown reaches T-10 mins they'll pause for half an hour and, if everything looks OK and they can fit it within the 2-hour window (opening 13:33 UK time), set a specific launch time.

Apparently there's a problem with one of the four main RS-25 engines and a crack has developed between two of the tanks. blogs.nasa.gov/artemis/2022/0… I'd suggest this makes today's #Artemis1 #SLS launch highly unlikely. #Artemis
Even if (as currently seems likely) today's #Artemis1 launch is scrubbed because of the issues, #NASA engineers will proceed as far as they can with the countdown as this is a test flight and they will want to test as many of the #SLS systems as possible. #Artemis
We're into an unplanned hold where it looks as if they may announce a scrub for today's #Artemis1 launch. Bearing in mind my previous tweet I wonder if they'll keep going with the countdown to test more of the systems. If they're swapping out an engine it might take several weeks
The #Artemis1 launch is indeed scrubbed for today (nothing to do with #SLS has ever happened on schedule). There is another launch window on Friday, but whether #NASA goes for that or returns the rocket to the VAB (Vehicle Assembly Meaning) we'll have to wait and see. #Artemis
