SpaceX Catches Booster But Loses Ship in Starship Test Flight

SpaceX’s seventh flight test of its massive Starship launch system brought good news as well as not-so-great news.

The good news? The Super Heavy booster successfully flew itself back to the Texas launch site and was caught above the ground by the launch tower’s chopstick-style mechanical arms. That’s only the second “Mechazilla” catch to be done during the Starship test program. The bad news is that the upper stage, known as Ship 33, was lost during its ascent.

“Starship experienced a rapid unscheduled disassembly during its ascent burn. Teams will continue to review data from today’s flight test to better understand root cause,” SpaceX said in a post-mission posting to X. “With a test like this, success comes from what we learn, and today’s flight will help us improve Starship’s reliability.”

Today’s test marked the first use of an upper stage that was upgraded with a redesign of the avionics, the propulsion system and the forward control flaps. Ship 33’s heat shield featured next-generation protective tiles as well as a backup layer of heat-resistant material. SpaceX had removed some of the tiles for this flight as a stress test for the heat shield.

During the webcast, an onscreen graphic suggested that Ship experienced engine problems during its ascent. “We saw engines dropping out on telemetry,” launch commentator Dan Huot said.

After Ship’s breakup, eyewitnesses posted videos showing a glittering hail of debris falling to Earth. Reuters reported that at least 20 commercial aircraft had to divert to different airports or alter their course to dodge the debris.

In response to an emailed inquiry, the Federal Aviation Administration said it was aware of the anomaly that occurred during today’s flight test and would be assessing the operation. “The FAA briefly slowed and diverted aircraft around the area where space vehicle debris was falling,” the agency said via email. “Normal operations have resumed.”

If Ship had made it to space, it would have deployed 10 Starlink simulators that were about the same size and weight as SpaceX’s Starlink broadband satellites. This was meant to test the procedure that SpaceX plans to use to put scores of Starlink satellites into low Earth orbit during a single Starship mission.

At the end of the flight test, Ship would have made a controlled re-entry and splashdown into the Indian Ocean.

Starship is the world’s most powerful launch system, with the booster’s 33 methane-fueled Raptor engines providing liftoff thrust of 16.7 million pounds. That’s more than twice the thrust of the Apollo-era Saturn V rocket, and almost twice the thrust of NASA’s Space Launch System, which was first launched in 2022 for the uncrewed Artemis I moon mission.

When fully stacked, Starship stands 403 feet (123 meters) tall. The system is meant to be fully reusable. Flight tests began in 2023, and SpaceX has made gradual progress. The first successful catch of the Super Heavy booster thrilled observers last October — and like that catch, today’s catch drew cheers from SpaceX employees watching the launch.

This year, SpaceX aims to demonstrate full reuse of Super Heavy and Ship, and promises to fly “increasingly ambitious missions.” The Starship system would be used for large-scale satellite deployments — and eventually for missions beyond Earth orbit. A customized version of Starship is slated to serve as a crewed lunar landing system for NASA’s Artemis III mission, which is currently scheduled for no earlier than mid-2027.

SpaceX founder Elon Musk envisions sending Starships on missions to Mars, perhaps starting in 2026. “These will be uncrewed to test the reliability of landing intact on Mars,” he said last September in a posting to X, the social-media platform that he owns.

“If those landings go well, then the first crewed flights to Mars will be in 4 years,” Musk said. “Flight rate will grow exponentially from there, with the goal of building a self-sustaining city in about 20 years.”
