The decision to use stainless steel materials and other design changes to SpaceX Starship should enable the first orbital mission in 2020. Design changes have dramatically improved the rocket and reduced development time.
Part of the rocket is cooled with liquid methane.
What about the chances that Starship will reach orbit in 2020?
