List of Starship flights

The SpaceX Starship is planned to be a fully reusable super heavy-lift launch vehicle.[1] The vehicle is under development by SpaceX, as a self-funded private spaceflight project.[2][3][4]

Starhopper

The second stage of Starship is designed as a long-duration cargo and passenger-carrying spacecraft in its own right, and is expected to be initially used without any booster stage at all, as part of an extensive development program to get launch and landing working and iterate on a variety of design details, particularly with respect to atmospheric reentry of the vehicle.[4][5][6][7]

Two (Starhopper, Mk1) test articles were being built by March 2019, and three (Starhopper, Mk1, Mk2) by May.[8] The low-altitude, low-velocity Starhopper was used for initial integrated testing of the Raptor rocket engine with a flight-capable propellant structure, and was slated to also test the newly designed autogenous pressurization system that is replacing traditional helium tank pressurization as well as initial launch and landing algorithms for the much larger 30-foot-diameter (9 m) rocket.[9] SpaceX originally developed their reusable booster technology for the 3-meter-diameter Falcon 9 from 2012 to 2018. The Starhopper prototype was also the platform for the first flight tests of the full-flow staged combustion methalox Raptor engine, where the Starhopper was flight tested with a single engine in July/August 2019,[10] but could be fitted with up to three engines to facilitate engine-out tolerance testing.[9]

The high-altitude, high-velocity 'Starship orbital prototypes' (everything after Starhopper) are planned to be used to develop and flight test thermal protection systems and hypersonic reentry control surfaces.[9] Each orbital prototype is expected to be outfitted with more than three Raptor engines.[11][12]
