A defect in one of the engines of the Starship, developed by SpaceX, could jeopardize the schedule established by NASA for sending astronauts back to the Moon. This incident occurred during the fourteenth test flight of the spacecraft, conducted in Texas.
Although the mission achieved significant milestones, such as the first commercial deployment of satellites, it was terminated a few hours ahead of schedule due to the unexpected shutdown of one of the three Raptor engines. This event may influence subsequent tests of the vehicle and, consequently, the Artemis program calendar.
The Raptor engine issue and NASA deadlines
Despite the failure, controllers managed to maintain the flight and execute the commercial satellite deployment after the Starship reached orbit and separated from the booster rocket. However, the problem gains great relevance due to the crucial role the vehicle will play in the lunar program.
SpaceX is developing a version of Starship intended to serve as a human landing system for NASA. This vehicle will rely on the same propulsion system to transport crew during activities on the lunar surface. For this reason, identifying the origin of the failure is essential.
According to aerospace engineer Dean Sladen of Accu Components, the degree of impact on development will depend on whether the problem is isolated to a specific part or indicates a design flaw requiring modifications across the entire fleet. Any adjustment to the engine that causes delays in upcoming flights, including the planned attempt to capture the vehicle with the launch tower arms after re-entry, will consume the existing schedule.
Dean Sladen, an aerospace engineer at Accu Components, told Reuters that the episode reignites focus on the Raptor engines. In its twelfth flight in May, one engine did not perform as expected, but in the following test in July, all engines operated during ascent.
Artemis 3 puts more pressure on Starship
A possible postponement will not only affect SpaceX's commercial plans, which also aims to expand its Starlink satellite network. For NASA, the most delicate issue lies in the company's participation in the Artemis program.
