Imagine a rocket tumbling uncontrollably back to Earth after a mission gone awry. That's exactly what happened recently with SpaceX's Falcon 9, forcing the company to ground its workhorse rocket. But here's where it gets controversial: while SpaceX has faced second-stage issues before, this latest anomaly raises questions about the reliability of their systems, especially as they prepare for crewed missions. Let's dive into what went wrong and why it matters.
SpaceX has temporarily halted Falcon 9 flights following a second-stage anomaly during a recent Starlink satellite deployment. According to a statement from SpaceX (https://x.com/SpaceX/status/2018485314508198331), the issue occurred during preparations for the deorbit burn, a critical maneuver designed to control the rocket's re-entry. The mission, launched from California on February 2 at 1547 UTC, successfully deployed 25 Starlink satellites, with the first stage completing its 31st flight and landing on the 'Of Course I Still Love You' drone ship in the Pacific Ocean. The first two second-stage engine burns were also successful, but the deorbit burn failed, leading to the stage's passivation instead.
And this is the part most people miss: Passivation, in this context, involves disposing of unused propellant to prevent an accidental explosion during re-entry. Without the deorbit burn, the stage re-entered Earth's atmosphere uncontrollably the following morning, between 0130 UTC and 0330 UTC, as noted by astronomer Jonathan McDowell (https://bsky.app/profile/planet4589.bsky.social/post/3mdyfmx2fls2g). SpaceX is now reviewing data to identify the root cause and implement corrective actions before resuming flights (https://www.spacex.com/launches/sl-17-32).
This isn’t the first time SpaceX has encountered second-stage problems. In July 2024, an explosion resulted in the loss of a Starship satellite payload (https://www.theregister.com/2024/07/15/spacexfaaprobe/), and in February 2025, debris from a failed deorbit burn rained down over Poland (https://www.theregister.com/2025/02/24/spacexfalcon9_debris/). These incidents highlight the challenges of space travel and the importance of thorough investigations.
The grounding of the Falcon 9 has already disrupted SpaceX's launch schedule. The next Starlink mission, originally slated for February 6 from Florida, has been postponed to February 14. More critically, the Crew-12 mission to the International Space Station (ISS), scheduled for February 11, is now in jeopardy. The ISS is currently operating with a reduced crew due to the early return of Crew-11 (https://www.theregister.com/2026/01/12/isscommandhandover/), making any delays particularly unwelcome.
During a briefing on the Artemis II post-Wet Dress Rehearsal, NASA confirmed that the investigation is ongoing. A space agency insider told The Register that SpaceX is confident the issue will be resolved in time for Crew-12, but cautioned that at least one fully successful mission would likely be required before a crew is onboard. The Federal Aviation Administration (FAA) is also involved in the investigation, though further details are pending. The Register has reached out to the FAA for comment and will provide updates as they become available.
Here’s a thought-provoking question: As SpaceX continues to push the boundaries of space exploration, how much risk is too much, especially when crewed missions are on the line?
