SpaceX successfully launched its Starship rocket for a fifth test flight on Sunday morning, showcasing a groundbreaking attempt to catch the returning Super Heavy booster using mechanical “chopsticks” attached to the launch tower.
The launch occurred at 8:25 a.m. ET (7:25 a.m. CT / 12:25 GMT) from SpaceX’s facility in Boca Chica, Texas, located near the Mexican border. This mission featured the Starship rocket and its Super Heavy booster, which were loaded with an impressive 10 million pounds of propellant. The flight marked an important step in SpaceX’s ongoing mission to enhance the reusability of its rockets, reducing both costs and environmental impact.
Innovative Booster Recovery Method
During the launch, just four minutes into the flight, engineers declared a “go for booster catch.” As the Super Heavy booster made its descent, a sonic boom echoed across the region—a thunderous noise produced when a vehicle travels faster than the speed of sound. Six minutes and 49 seconds after liftoff, the Super Heavy booster successfully maneuvered back to the launch tower.

Using SpaceX’s innovative “chopsticks,” known as “Mechazilla,” it was captured with remarkable precision, marking a historic achievement in rocket recovery technology.
The Starship itself, equipped with six Raptor engines, is designed for high-performance missions and has the capability to transport over 200 tons to orbit. Meanwhile, the Super Heavy booster is powered by an astounding 33 Raptor engines. This launch also featured a new heat shield composed of 18,000 ceramic tiles, designed to endure temperatures reaching up to 2,600 degrees Fahrenheit (1,400 degrees Celsius). The testing of the heat shield is crucial, especially in light of the challenges encountered during previous flights.
Addressing Regulatory Hurdles
Leading up to the launch, SpaceX had been open about the regulatory hurdles and environmental concerns it faced. Issues regarding the water deluge system and the potential impacts of sonic booms from the booster’s return had been topics of discussion. However, with the necessary regulatory approvals in hand, the company proceeded with this groundbreaking test flight.
After the successful liftoff, the Starship and Super Heavy booster separated as planned. The Super Heavy executed a complex maneuver to return to the launch site, while the Starship continued its mission, aiming for a controlled reentry and splashdown in the Indian Ocean. This aspect of the flight aimed to further assess the performance of the heat shield and reentry capabilities, particularly after challenges faced in earlier tests.
