Designed with Mars colonization in mind, SpaceX’s Starship is huge. First contemplated by SpaceX back in 2012, the Starship name was announced in 2018 at the same time as the first mission, to fly around the far-side of the Moon, was purchased by Japanese e-commerce billionaire Yusaku Maezawa. That mission is forecast to take place in 2023. Quite an ambitious schedule for such a complex system, but SpaceX seems to be dedicating huge resources towards the effort, and testing is well underway.
The combination of the Starship and its booster rocket will be 122m tall and 9m diameter. Starship can transport huge payloads into space. This massive sizes means that people on-board would have much more space to move around in, than the capsule systems detailed above.
We are keeping a close eye on the Starship development. It’s a very exciting program.
