SpaceX successfully tests its “Grasshopper” reusable rocket
The problem with modern space travel is that while rockets are good at getting us past the atmosphere, at best, only parts of the rocket can be reused. It’s sort of like if you had to buy a whole new engine for your car every time you went somewhere— it gets really expensive. People have tried in the past to make a reusable rocket, and this past week, SpaceX successfully launched its “Grasshopper” rocket 12 stories in the air. Not even close to orbit, but it’s something.
