SpaceX is preparing to make another attempt at launching its massive Starship spacecraft from South Texas on Thursday, with the company planning to test a series of hardware and software improvements developed after problems during its previous flight.
The launch is expected to take place from the company’s Starbase facility near Boca Chica Beach. The planned 90-minute launch window is scheduled to open at 5:45 p.m., although the timing could change depending on weather conditions, technical checks or other factors that can affect the launch of the world’s largest and most powerful rocket system.
The flight will mark SpaceX’s 13th Starship test mission and is expected to serve as another major test of the spacecraft’s ability to launch, separate from its booster, conduct in-space operations and complete a controlled return.
The company’s previous launch attempt was called off last week after several engines failed to start before the countdown reached zero. SpaceX CEO Elon Musk said the launch was scrubbed because of the engine-startup problems, forcing engineers to examine the system before attempting another flight.
For the upcoming mission, SpaceX plans to test modifications intended to improve the performance and reliability of both the Super Heavy booster and the Starship spacecraft.
The Super Heavy booster will be tasked with completing a sequence that includes liftoff, ascent, stage separation, a boostback burn and a landing burn. Engineers have modified parts of the booster’s hardware in an effort to improve the reliability of engine relights, a critical part of the vehicle’s planned return and recovery operations.
The Starship spacecraft will also have several major objectives during the test. SpaceX plans to deploy 20 Starlink satellites for the first time during a Starship mission, adding an important demonstration to a flight that is already designed to test multiple systems.
The spacecraft is also expected to attempt an engine relight while in space before beginning a controlled reentry and descent toward a planned splashdown location in the Indian Ocean.
SpaceX is also continuing to evaluate and improve Starship’s heat shield, which is one of the most important systems required for the spacecraft to eventually return safely from space. During reentry, the vehicle must withstand extreme heat as it travels through Earth’s atmosphere at high speed.
The upcoming flight follows a previous test in which SpaceX encountered difficulties with both the Super Heavy booster and the Starship vehicle.
During the last flight, differences in engine startup behavior on the spacecraft reportedly caused the booster’s directional flip to deviate significantly from its intended orientation. Several booster engines also failed to reignite as expected, causing the boostback burn to end earlier than planned.
The Federal Aviation Administration later cited heat-related effects on propulsion system components during ascent, along with incorrect settings in the engine alarm system, as contributing factors in the booster’s problems. SpaceX has said that changes have been made to address those issues before the next test.
The Starship spacecraft also experienced an engine failure during the previous mission. Despite losing one engine, the vehicle continued along its planned trajectory and demonstrated that it could maintain flight under difficult conditions.
Each Starship test flight is designed to gather data that can be used to improve the vehicle’s systems. Unlike a traditional launch in which every mission is expected to operate perfectly, SpaceX’s development program relies heavily on repeated flight testing to identify weaknesses and make changes before the next attempt.
The Starship system is central to SpaceX’s long-term plans for transporting people and cargo to the Moon and, eventually, Mars. NASA has also selected a version of Starship for planned lunar missions under its Artemis program, making the vehicle’s development closely watched by the space industry and government agencies.
Thursday’s launch attempt will therefore be closely monitored as SpaceX continues working toward a fully reusable transportation system capable of carrying large payloads into orbit and returning its components for future flights.
The launch could still be delayed if technical or weather-related issues arise. However, if the mission proceeds as planned, the flight will provide SpaceX engineers with another opportunity to test the Starship system, demonstrate new capabilities and gather valuable data from one of the most ambitious rocket-development programs in the world.
