Autonomous spaceport drone ship

Autonomous spaceport drone ships are a type of boat that travels out to sea and helps recovering rockets after they Launched into space. It’s kind of like when a firefighter uses a big net to catch someone when they jump out of a burning building. The drone ship's job is to catch the rockets as they come back from space and take them back to the spaceport so that they can be used again in the future. It is able to do this because it is autonomous, meaning it is able to move around on its own and make decisions on where to go and what to do.
