Second test flight of the two-stage Starship launch vehicle. The booster is expected to separate 170 seconds into flight and return to land approximately 32 km off the shore in the Gulf of Mexico. The second stage will follow a suborbital trajectory and perform an unpowered splashdown approximately 100 km off the northwest coast of Kauai (Hawaii).

First development version of the Starship reusable two-stage super heavy-lift launch vehicle.

  Technology
  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.
