First up is SpaceX. They’re arguably the boldest in their endeavors to reach the red planet. The timeline officially begins in 2018, where SpaceX plans on using their Falcon Heavy rocket to help launch one of their Dragon spacecrafts to Mars. But it doesn’t stop there. By 2020, the company will begin their initial development and testing of the Interplanetary Transport System (ITS) booster. And this booster is no joke. Larger than the Saturn V rocket, the ITS booster will be 122 meters tall and around 12 meters wide. Enormous!

As for the spaceship, of which has already been given the name “Heart of Gold” (paying homage to Douglas Adams’ “The Hitchhiker’s Guide to the Galaxy”), this ship is incredibly large as well. The ship will be measuring at around 50 meters long and 19 meters wide – just big enough to carry 100 people per flight to Mars by 2024, including their luggage and various other extracurricular activities to make the journey fun and comfortable.
