SpaceX has launched its biggest, most powerful Starship yet on a test flight, an upgraded version that NASA is counting on to land astronauts on the moon.The redesigned mega rocket made its debut two days after SpaceX chief Elon Musk announced he's taking the company public in a potentially record initial public offering.The rocket blasted off from the southern tip of Texas, carrying 20 mock Starlink satellites for release halfway around the world.The mammoth rocket blasted off into space at just after 5.30 pm local time The goal this time is a moon base near the lunar south pole, staffed by astronauts as well as robots."We're looking forward to seeing this fly, because hopefully at some point in the not-too-distant future we're going to join up in Earth orbit," NASA Administrator Jared Isaacman said during the pre-launch SpaceX program ahead of Friday's test.Following the test, Isaacman posted praise on X, congratulating SpaceX on "a hell of a V3 Starship launch.""One step closer to the Moon...one step closer to Mars," the NASA official said.SpaceX is already taking reservations for private flights to the moon and Mars on Starship, though the timing is uncertain.For the latest from SBS News, download our app and subscribe to our newsletter.
