Worthless thread since no one knows what the F SLS is.
SLS is, or was, the super-heavy lift rocket that was supposed to take us back to the moon. Designed by lawyers in Congress (”you’ll re-use Shuttle tech and keep my constituents employed no matter what”), it’s flown once and is projected to cost $2 billion a copy. Once Musk gets Starship perfected, he’ll have a better rocket that costs ... I don’t know, but I’d guess around 1/4th the cost of SLS per launch.
