Interplanetary Transport Network

Interplanetary transport network is a way to get from one planet to another in our solar system quickly. It works by shooting a rocket off to a planet, then having a spacecraft (like a car or bus) that can travel through space and land on the other planet. The spacecraft will use a lot of fuel, but will be able to take people and things to other planets and moons much faster than if they had to be sent in a rocket. This way, if people needed to visit another planet or moon, they could do it much faster and cheaper than before!
