Starship 25 Stacking on Booster 9

SpaceX Starship

The SpaceX Starship is a fully reusable super heavy-lift launch vehicle under development by SpaceX since 2012, as a self-funded private spaceflight project. The second stage of the Starship — is designed as a long-duration cargo and passenger-carrying spacecraft. It is expected to be initially used without any booster stage at all, as part of an extensive development program to prove out launch-and-landing and iterate on a variety of design details, particularly with respect to the vehicle's atmospheric reentry.
