SpaceX Starship engine failure could impact NASA moon mission schedule

A recent engine failure during the 14th uncrewed test flight of SpaceX's Starship rocket may complicate NASA's timeline for sending astronauts to the moon. The test launch took place in Texas on Monday, September 28, 2026.

Flight Details

While Starship met several key goals during the test, the mission was cut short by several hours after its propulsion system malfunctioned. One of its three main Raptor engines shut down unexpectedly after the spacecraft separated from its lower-stage booster rocket. Even with this glitch, flight controllers sent the craft to orbit to complete its first-ever commercial satellite deployment.

Impact On NASA

Finding the cause of the engine problem is important for SpaceX, but the stakes are higher for NASA. The Artemis moon-landing vehicle depends on the same engine system to carry astronauts to and from the lunar surface. Dean Sladen, an aerospace engineer for Accu Components, noted that the severity of the delay depends on whether it is a single faulty part or a larger design flaw requiring upgrades across the fleet. Any engine fix that delays upcoming flights also eats into the schedule for the planned attempt to catch the ship using launch tower arms after re-entry.

Reactions And Competition

SpaceX did not immediately respond to requests for comment. A NASA spokesperson did not answer questions about the engine issue or the Artemis programme, but pointed to a post on X by space agency head Jared Isaacman stating that Starship achieved an important milestone. SpaceX is competing with Jeff Bezos's Blue Origin to provide a lunar lander for NASA. Isaacman stated in April that NASA will use whichever lander is ready first, and NASA views this competition as healthy due to earlier flight delays. NASA aims to land astronauts on the moon by 2028, while China plans a crewed lunar landing by 2030.

Context

Space exploration timelines often face adjustments as engineers test complex new hardware under flight conditions. Reusable rocket systems and heavy-lift vehicles require extensive testing to ensure safety before carrying human crews into deep space.
