Ken: Welcome. You seem however to be reading older links on my webpage and slowly working your way to the present. :)

1. It is absolutely wise to test a rocket prior to launch. If it can’t take the strain of that test, it shouldn’t be launched to begin with. Moreover, SLS uses as its firsts stage engines the engines used on the shuttle. These were designed for many reuses.

3. I am not sure I understand your second question. Based on NASA past practice with the rockets it has built, once they have tested a new rocket and are satisfied it works, they end tests. With SLS, as far as I know they do not intend to do a Green Run test on the second SLS mission.

Either way, SLS is so unwieldy that it is impossible for NASA to use the second launch as a tool to speed up the first. The second rocket is not really even built yet.

A couple of questions:

1) Is it wise to reuse the core stage tanks after an 8 minute burn?

2) Could Artemis 2 be build concurrently with the Green Run test so that it could be redirected to Artemis 1? Then the Green Run test core be used for Artemis 2?
