SLS

NASA doesn’t plan to use it very much. This isn’t really news, but it’s nice to see them point out the implications:

Given the SLS Block 1 launch processing manifest (4-5 years with little to no activities), there is a potential of not having sufficiently trained personnel. Issue – Yellow (May require personnel with advanced skills not readily available).

As I write in the book, even ignoring the cost implications:

From a safety standpoint, it means that its operating tempo will be far too slow, and its flights too infrequent, to safely and reliably operate the system. The launch crews will be sitting around for months with little to do, and by the time the next launch occurs they’ll have forgotten how to do it, if they haven’t left from sheer boredom to seek another job.

What a mess.
