Elon Musk’s SpaceX this week once again lost the upper stage of its massive Starship rocket in a fiery explosion, even as the booster was successfully caught in its orbital test — a near replay of the previous attempt.

Minutes after liftoff and booster separation, a live video feed showed the upper stage tumbling uncontrollably before the signal abruptly cut.

Dramatic footage circulating online showed red-hot debris raining down over the Bahamas.

“Can confirm we did lose contact with the ship. Unfortunately, this happened last time, too,” SpaceX spokesman Dan Huot said, referring to January’s flight, which also ended with the upper stage disintegrating over the Caribbean.

The fallout immediately impacted US airspace.

The Federal Aviation Administration (FAA) briefly activated a “debris response area,” delaying flights from airports stretching from Newark and Philadelphia to Miami.

The agency confirmed SpaceX will be required to conduct an investigation before it can fly again.

SpaceX said in a statement that an “energetic event in the aft portion of Starship” had “resulted in the loss of several Raptor engines.”

“This in turn led to... ultimately a loss of communications with Starship,” it said, adding there were “no toxic materials present in the debris.”

“We will conduct a thorough investigation, in coordination with the FAA, and implement corrective actions.”

Dominant launcher

Despite the setback, SpaceX’s “fail fast, learn fast” approach has helped it become the world’s dominant launch services provider.

But Musk’s status as one of President Donald Trump’s closest advisors, and his influence over federal regulators, are raising concerns about potential conflicts of interest.

Starship — the world’s largest and most powerful rocket — lifted off from SpaceX’s Starbase facility in Boca Chica, Texas, shortly after 5:30 pm (2330 GMT).

It marked its eighth uncrewed orbital test, after launch attempts were scrubbed on Monday and Wednesday.

While the upper stage was lost for a second consecutive flight, SpaceX successfully recovered the Super Heavy booster, catching it with the launch tower’s mechanical “chopstick” arms for the third time — an impressive feat of engineering.

About 40 minutes after launch, SpaceX ended its livestream, without providing further details.

Standing 403 feet (123 meters) tall — about 100 feet taller than the Statue of Liberty — Starship is designed to eventually be fully reusable and is key to Musk’s long-term vision of colonizing Mars.

NASA is also awaiting a modified version of Starship as a lunar lander for its Artemis program, which aims to return astronauts to the Moon this decade.

But before SpaceX can carry out those missions, it must prove the vehicle is reliable, safe for crew, and capable of complex in-orbit refueling — critical for deep space missions.

The FAA previously grounded Starship after its 16 January flight ended in an upper-stage explosion.
