On the evening of December 9, 2020, SpaceX was able to accomplish a historic first, almost all objectives of its suborbital 12.5km test flight of the SpaceX experimental Starship SN8 spacecraft. Starship is the proposed second-stage of a fully reusable earth to orbit launch system that would significantly reduce the high cost of orbital launches and enable the eventual settlement of Mars.

The Starship is itself only a second stage. It is to be launched above a Starship Heavy Booster. As envisioned, the Heavy Booster will return to earth and land vertically in the manner of current SpaceX's Falcon 9 rockets. The second stage Starship however, will be able to reach orbit with sufficient fuel to deorbit and reland using a novel aerobraking mechanism whereby it reorients into a horizontal inclination during atmospheric reentry with the use of its four flaps, raptor engines and cold gas thrusters. Just prior to landing, it reverts to a vertical orientation, reignite its engines at the final moment to decelerate to touch down vertically.
