Artemis 1

Jay Parini: SLS is a space launch system, some people describe it as a fleet and space-long system. He says there's going to be different versions of this in the future. Parini: The lack of reusability for SLS was kind of annoying after so much time watching SpaceX. But now he sees where they're coming from; at least financially speaking, the case for reusability is less strong on that front.
