Two veteran NASA astronauts are now on their way to the International Space Station. This particular commute to the space station is a major moment in American space travel. On this first crewed launch, Boeing has proved that it is not a disaster. It’s also the primary contractor for NASA’s newest rocket, the Space Launch System, which is scheduled to launch astronauts toward the moon later this decade. By now NASA astronauts have flown on SpaceX often enough that it’s hardly a blip on space watchers’ radar.
