Everyone has heard of SpaceX's Starship. "SpaceX's Starship and Super Heavy Rocket represent a fully reusable transportation system designed to service all Earth orbit needs as well as the Moon and Mars," explains SpaceX's site.

"This two-stage vehicle—composed of the Super Heavy rocket (booster) and Starship (ship)—will eventually replace Falcon 9, Falcon Heavy and Dragon. By creating a single system that can service a variety of markets, SpaceX can redirect resources from Falcon 9, Falcon Heavy and Dragon to Starship—which is fundamental in making the system affordable."

But did you know that Starship is made of stainless steel? The material is an odd choice as the material has been considered unsuitable for flight structures since the 1960s since it is much too heavy.

So why did Elon Musk and SpaceX choose it for their Starship? Lucky for us YouTube channel Real Engineering explored the question in their video.

The clip is a must watch for any SpaceX fan or simply a space exploration fan. It also explains other qualities of the ship like its design.
