SpaceX launches super-heavy rocket Starship, signals intent to 'go where no man has gone before'

SpaceX launched its giant Starship-Super Heavy rocket from Texas on Monday on the spacecraft’s first flight intended to reach Earth orbit, marking a major milestone in Elon Musk’s plans to develop a fully reusable transportation system for missions to the Moon, Mars and beyond.

The 124-metre-tall rocket lifted off from Pad 2 at SpaceX’s Starbase facility in South Texas on its 14th integrated test flight. While the previous 13 Starship flights had followed suborbital trajectories, Flight 14 was designed to place the Starship upper stage into orbit for the first time and keep it in space for nearly 10 hours.

Starship targets orbit

Powered at liftoff by 33 methane-fuelled Raptor engines on its Super Heavy booster, the Starship system began its ascent before the upper stage separated through SpaceX’s “hot staging” process. The mission represented a substantial step beyond the roughly hour-long trajectories used during earlier Starship tests.

The flight plan called for Starship to reach an altitude of about 275 km and complete approximately six orbits of Earth. SpaceX also planned to demonstrate an in-space Raptor engine burn before bringing the spacecraft back through the atmosphere for a controlled splashdown in the Pacific Ocean west of Chile.

The Super Heavy booster, meanwhile, was scheduled to perform a controlled return and splash down in the Gulf of Mexico. SpaceX did not plan to attempt a tower catch of either vehicle during the mission.

Starlink satellites aboard

Flight 14 also marked Starship’s first planned deployment of an operational payload. The spacecraft carried 26 next-generation Starlink V3 satellites intended to join SpaceX’s expanding broadband constellation.

The deployment is significant for SpaceX because the much larger Starship is intended eventually to replace Falcon 9 as the principal vehicle for launching new generations of Starlink spacecraft. The V3 satellites have been designed with considerably greater communications capacity than earlier generations.

Three of the satellites were also equipped with cameras intended to photograph Starship’s heat shield after deployment. The imagery is expected to provide engineers with additional information about the spacecraft’s thermal protection system before its return through Earth’s atmosphere.

Testing reusability

Starship and Super Heavy have been designed as a fully reusable launch system, with SpaceX eventually intending to recover both stages for rapid turnaround and repeated flights. The company has previously demonstrated catches of the Super Heavy booster using the giant mechanical arms of its launch tower, although Monday’s mission instead called for an ocean splashdown.

Flight 14 was designed to test several technologies crucial to making that reusable architecture practical, including orbital operations, satellite deployment, an in-space engine burn and controlled atmospheric re-entry.

The spacecraft’s heat shield remains particularly important because Starship must withstand extreme temperatures while returning from orbital velocity. Data from Monday’s mission will be used to refine the vehicle as SpaceX moves towards more frequent orbital operations.

Moon and Mars ambitions

The test has implications beyond SpaceX’s commercial Starlink programme. A modified version of Starship has been selected as a lunar lander for NASA’s Artemis programme, which aims to return astronauts to the Moon.

Future lunar missions will require SpaceX to demonstrate technologies including orbital refuelling, under which Starship tankers would transfer propellant to a lunar-bound spacecraft in Earth orbit. Achieving reliable orbital operations with Starship is therefore an important prerequisite for those plans.

Musk’s longer-term ambition is to use fleets of reusable Starships to transport large quantities of cargo and eventually people to Mars. SpaceX has repeatedly described full and rapid reusability as central to reducing the cost of space transportation enough to make such missions practical.

Major milestone for SpaceX

Monday’s launch came 18 years after SpaceX’s Falcon 1 became the company’s first rocket to reach orbit in September 2008. Since then, SpaceX has developed the Falcon 9 and Falcon Heavy systems and built its Starlink satellite constellation while pursuing increasingly ambitious reusable rocket technology.

Starship represents a much larger step in that strategy. At more than 120 metres tall and producing roughly 16 million pounds of thrust at liftoff, the integrated Super Heavy-Starship vehicle is the largest and most powerful rocket system yet flown.

Flight 14’s success will ultimately be judged across several stages rather than liftoff alone, including orbital insertion, deployment of the 26 Starlink V3 satellites, the planned in-space engine burn and Starship’s controlled return to Earth.
