SpaceX Finally Successfully Lands Rocket

Earlier today, SpaceX finally landed a booster rocket after sending a payload into space. They’ve had several attempts that came close to succeeding but didn’t quite make it. Landing the booster is potentially important because it means that we may be close to having reusable rockets, which might lower the cost of a launch by some significant amount. I’ve never sent anything into space, so I can’t really say exactly where all the money goes, but I imagine that the rockets must be quite expensive if so much effort has been put into a recoverable and reusable rocket system.
