A payload hit is acceptable if the reusability is very great: they can just truck up bits of spacecraft, fuel for depots, crew modules and so on in many runs. A fully-featured spaceplane is a paradigm-shifter. SpaceX decided not to try because the tech was too far down the line. Novel propulsion takes decades to prove out, and Reaction are working through it reasonably. The sticking point was the hypersonic precooler, and they've cracked that. A whole-engine scale demonstrator should be a relatively straightforward next step. |
