Make astronauts More realistic, like you can select what spacesuit they will wear, if they fell from a high place, be near or inside an explosion, if they go so fast inside capsule (mach number 3-5,same thing will be applied for astronauts inside a plane), they or inside the capsule they in (for this suggestion, capsule interior heat also needed) gets too hot, their oxygen runs out (to get oxygen they will use oxygen tanks [new parts] or get in capsule [and not seat]) they will die or pass out, if astronauts are or capsules with astronauts inside are primary, you will be unable to control the rocket without switching onto a conscious astronaut or a chip.
