The problem is that using a parachute means that--assuming your launching from Houston or Cape Canaveral--you&#x27;re only going to be able to land in the ocean. With just a parachute, can you recover the booster and make it launchable in, say, a day? That&#x27;s kind of the goal: to make rockets more like cars and less like soda cans, i.e. to reuse vs. recycle.
