Elon Musk is building a super-powerful rocket called Starship, and it's going to take people to Mars!
First, Starship will travel to Mars without any people on board. It's like a test drive to make sure it lands safely.
If the test goes well, people will be able to fly to Mars on Starship in a few years! They might even walk on Mars!
Elon wants to build a whole city on Mars, so we can live on another planet one day.
