A rocket named Starhopper made its first flying test hop at SpaceX’s Boca Chica proving that it works.The Test took place in South Texas July 25th 2019, which happened to be one day after a glitch had forced the Starhopper to abort. The Starhopper had ignited its single Raptor engine right before midnight. It had apparently fired long enough to meet the test’s main objective, a straight hop of 20 meters up and down.
"Starhopper test flight successful," Musk wrote on Twitter after the test. "Water towers *can* fly haha!!"
