SpaceX has completed a second low-altitude test flight of its ‘Starhopper’ demonstration prototype, which is being used to test technologies that will be used to build the full-scale next-generation SpaceX ‘Starship’ spacecraft. This test involved ‘hopping’ the Starhopper (hence the name, get it?) to a height of around 150m (or a little under 500 feet), the highest it’s flown so far, at a SpaceX test facility in Texas. After the hop, which lasted around 50 seconds (the GIF above is sped up 2X) it successfully navigated itself to a target landing pad a short distance away.
This is the second untethered test trip for the Starhopper, and will is intended to be its last, as SpaceX moves forward with construction of its Starship Mk I and Mk II prototypes, which is taking place currently and simultaneously at sites in Florida and Texas. Today’s attempt was the second try after a planned test yesterday was aborted at the last second, with SpaceX resetting and ensuring everything was in place for this longer hop, which lasted just under a minute.
In July, SpaceX ran its first untethered hop, which is designed to test the operation of the Raptor engine SpaceX is developing for Starship, along with other subsystems for use in the production Starship. That flew only for around 22 seconds, and attained a height of just 20 meters (a little over 65 feet).
Construction is currently in progress at both SpaceX’s Texas and Florida facilities on its full-scale Starship prototypes, which SpaceX CEO Elon Musk is ambitious will begin their own flight testing later this year, in perhaps as little as a few months. The larger prototypes, which should be closer to what will actually launch, will test more Raptor engines working together and aim to fly to higher altitudes, another key step as the company works towards a true first orbital test flight.
Ultimately, SpaceX is hoping to replace both Falcon 9 and Falcon Heavy entirely with different configurations of Starship, which will help the company in terms of cost efficiency thanks to its fully reusable nature, and streamlining all of its rocket construction efforts around one type of vehicle.
