SpaceX's Starhopper prototype is at the end of its rope, literally.
In a nighttime test Friday (April 5), the squat hopping testbed for SpaceX's future Starship spacecraft reached the end of its tether, rising what appears to be a few feet or more above the ground at its launch site. SpaceX performed the test at the company's Boca Chica test site near Brownsville, Texas, with the tether serving as a safety line on the vehicle.
