SpaceX Starship Reaches Orbit for First Time Despite Engine Failure

SpaceX successfully placed its Starship rocket into Earth’s orbit for the first time despite an engine failure during the ascent.

The rocket launched at 7:48 a.m. local time, representing the 14th test flight of the system. While SpaceX has flown the full Starship configuration since 2023, previous attempts utilized suborbital trajectories. This mission required the rocket to reach a speed of approximately 28,000km/h (17,400mph) to maintain orbit, a technical threshold not previously met by the vehicle.

Engine Failure and Orbital Trajectory

An engine failure occurred during the ascent, which initially threatened the mission’s ability to reach orbit.

The rocket reached an altitude of about 171 miles (275km). SpaceX originally planned for the craft to complete six loops of Earth over nearly 10 hours. However, more than an hour into the mission, the company announced that Starship would return early, targeting a landing in the north Pacific approximately three hours after launch.

During the flight, the Starship upper stage separated from the Super Heavy booster. The booster returned to an offshore landing point in the Gulf of Mexico. SpaceX did not attempt to catch the booster with mechanical arms during this specific flight.

Hardware Modifications and Satellite Deployment

Engineers implemented hardware and software changes to address failures seen in the previous test flight.

Beyond the orbital test, the mission served a commercial purpose by deploying 26 next-generation Starlink satellites.

Implications for NASA and Space Industry

The successful orbit is a prerequisite for NASA’s plans to use Starship to transport astronauts to the moon. Martin Barstow, a professor of astrophysics and space science at the University of Leicester, stated that the achievement is transformational for the space industry.

This is an important milestone for SpaceX, with Starship successfully reaching orbit, and at the first attempt. This marks the beginning of the transition from the testing and development phase to becoming a working vehicle able to deliver the large payloads needed to return to the moon.

Market Context and Public Offering

The mission follows SpaceX’s entry into the public stock market in June.

The shift to orbital flights also increases the complexity of risk management. Suborbital flights are designed so that malfunctions result in debris falling into the Indian Ocean.
