More Flights of SLS Block 1
NASA is apparently having problem with their new upper stage and is
now planning on flying at least the next three missions on the original SLS Block 1 hardware. Current estimates say the new upper stage won't be ready until at least the mid-2020's. This means a couple of things. 1) NASA is talking about flying three missions and using 12 of their small stock of Shuttle engines on missions that don't really further their plans. Block 1 hardware with Ares on it is about 9 tonnes short in payload, which means none of the Lunar Gateway deployment can happen. 2) They could just as easily fly those missions on something like Falcon Heavy and save a lot of money (and those engines). By the time they get the new upper stage ready, they'll need funding for a new contract to produce more engines so that Block 1B can fly. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man." --George Bernard Shaw |
