SpaceX`s Starship rocket, designed to eventually send astronauts to the moon and beyond, completed nearly an entire test flight through space on its third try on Thursday, getting farther than ever before, but disintegrated on its return to Earth.

During a webcast of the flight, SpaceX commentators said mission control lost communication with Starship from two satellite systems simultaneously while the spacecraft was re-entering the planet`s atmosphere at hypersonic speed.

The spacecraft at that point was nearing a planned splashdown in the Indian Ocean, about an hour after launch from south Texas.

Contact with Starship cut out moments after a live video feed from a camera mounted on the vehicle showed high-definition images of a reddish glow enveloping the silvery spacecraft from the heat of re-entry friction as it plunged earthward.

A few minutes later, SpaceX confirmed that the spacecraft had been "lost" - meaning incinerated or broken apart - during the stress of re-entry.

For reasons that were left unclear, SpaceX opted to skip one of the test flight`s core objectives - an attempt to re-ignite one of Starship`s Raptor engines while it coasted in a shallow orbit. That milestone is considered key to its future success.

Still, completion of many of Starship`s intended flight objectives represented progress in the development of a spacecraft crucial to the growing satellite launch business of SpaceX, founded by Elon Musk in 2002, and NASA`s moon program.

NASA chief Bill Nelson congratulated SpaceX on what he called "a successful test flight" in a statement posted on social media platform X. The US space agency is SpaceX`s biggest customer.
