SpaceX Grounds Falcon 9: What Went Wrong with the Second Stage? | Full Analysis (2026)

A recent incident has SpaceX in a tricky situation, and it's all about the Falcon 9's second stage. The rocket's unexpected behavior has grounded the Falcon 9 fleet, and the implications are far-reaching.

Let's dive into what happened. During a routine mission on February 2nd, the Falcon 9's second stage malfunctioned, leading to an uncontrolled re-entry back to Earth. SpaceX described it as an "off-nominal condition" during the deorbit burn preparation. In simpler terms, the rocket's second stage didn't behave as expected, and it couldn't control its descent.

The mission had successfully deployed 25 Starlink satellites, and the first stage made a smooth landing. But the deorbit burn, which ensures a targeted re-entry, didn't happen. Instead, the stage was passivated, meaning they had to dispose of the unused propellant to prevent any explosions during re-entry.

But here's where it gets controversial: This isn't the first time the second stage has caused issues. In 2024, an explosion led to the loss of a Starship satellite payload, and in 2025, uncontrolled re-entry showered debris over Poland. These incidents raise questions about the reliability of the Falcon 9's second stage.

SpaceX is now reviewing the data to determine the root cause and find solutions before resuming flights. However, they haven't specified how long the Falcon 9 will remain grounded. The launch manifest has already been shuffled, with missions delayed, including the next Starlink launch, which was pushed from February 6th to the 14th.

And this is the part most people miss: The implications extend beyond just delayed missions. The Crew-12 mission to the International Space Station (ISS), scheduled for February 11th, is now in jeopardy. The ISS is already operating with a reduced crew due to an early return, so any delay is a significant setback.

NASA, during a briefing on the Artemis II mission, noted that the investigation is ongoing. An insider revealed that SpaceX is confident about resolving the issue in time for the Crew-12 launch, but they also cautioned that a fully successful mission might be necessary before loading a crew.

The Federal Aviation Administration (FAA) is also involved in the investigation, adding another layer of complexity. As we await further updates, one thing is clear: SpaceX has a challenging road ahead to restore confidence in the Falcon 9's reliability.
