Starship, meanwhile, has continued to sail through space at more than 26,000 km/h at an altitude of 270 km.
SpaceX launched its Starship megarocket on a test flight that was expected to end with the vehicle returning to the launch tower, where the rocket was to be caught for reuse.
If all goes to plan, it would be the first time SpaceX has caught the rocket's 171ft upper stage.
The entire rocket was expected to be grabbed in the launch tower's"chopstick"mechanical arms.
Musk has cast his reusable rocket as a buffer against the enormous costs associated with future space travel.
The data plays a role in determining if the spacecraft is ready to return for the catch.
Early in the webcast, SpaceX simulated the return the flight was expected to attempt.
As smoke plumes wafted from the launch site, SpaceX employees erupted into cheers.
Flights to the west coast from Hawaii were temporarily paused because of space debris from the launch, the island's transportation agency said.
Those flights resumed on Friday, the island's transportation agency said, after the temporary pause.
SpaceX has launched a flurry of test flights in recent years, some of which have resulted in explosions that signaled major design flaws.
The spacecraft remained aloft at that speed and altitude, with any return still tied to the data.
