Elon Musk has reported that SpaceX is building the body of the Starship out of stainless steel and that it will be polished to a mirror finish.

A hopper version of the Starship should have its first test flights by April 2019. The Super Heavy should reach orbit in 2020.

This vehicle will be completely reusable and will be able to carry 100 tons to low earth orbit with each launch.
