SLS put a capsule into orbit for an absolutely princely sum of $4.1 billion
per launch. That's after the over $20 billion program cost. All using technology largely designed in the 70's. But at least those the designs of the 70's were meant for reuse were as SLS is completely disposable. The entire program makes the space shuttle seem like a bargain. Now that's an accomplishment.
> Additionally, pinning the entirety of the American space program on a single private company seems like a recipe for disaster.
That's exactly what happened here. America pinned the entire project on Boeing Space. With disastrous results.
