SpaceX's uncrewed spacecraft Starship, developed to carry astronauts to the moon and beyond, was presumed to have failed in space minutes after lifting off on Saturday in a second test after its first attempt to reach space ended in an explosion.
The two-stage rocketship blasted off from the Elon Musk-owned company's Starbase launch site near Boca Chica in Texas, soaring roughly 55 miles (90 km) above ground on a planned 90-minute flight into space.
But the rocket's Super Heavy first stage booster, though it appeared to achieve a crucial maneuver to separate with its core stage, exploded over the Gulf of Mexico shortly after detaching.
Meanwhile, the core Starship booster carried further toward space, but roughly 10 minutes into the flight a company broadcaster said that SpaceX mission control suddenly lost contact with the vehicle.
"We have lost the data from the second stage... we think we may have lost the second stage," SpaceX's livestream host John Insprucker said.
The launch was the second attempt to fly Starship mounted atop its towering Super Heavy rocket booster, following an April attempt that ended in failure about four minutes after lift-off.
