No problem, right? Well, uhmm, NASA isn’t quite ready to cover this:
“Unfortunately, SLS, which is consuming about $3 billion of NASA’s annual budget, won’t be ready to fly crew until 2021. And after that, it will be able to fly missions only once every four years under the current development schedule. So the multiple flights per year needed to maintain the International Space Station won’t happen with SLS unless things change.”
