SpaceX has paused Falcon 9 launches after an issue with the rocket’s upper stage that emerged at the end of a recent launch. On February 2, a Falcon 9 lifted off from Vandenberg Space Force Base in California at 10:47 a.m. Eastern. The rocket successfully deployed 25 Starlink satellites into low Earth orbit about an hour after liftoff.
Later that day, SpaceX issued a statement noting that the upper stage “experienced an off-nominal condition” while preparing for a final engine burn to deorbit. They couldn’t provide specific details but confirmed everything went smoothly until that point.
SpaceX indicated that the upper stage took steps to “passivate” itself, a process that reduces risk by venting unused propellants and discharging batteries. They are currently analyzing data to find the root cause of the issue before resuming launches.
The company did not give a timeline for this process but listed the next Falcon 9 mission for February 5, which was pushed back from February 3.
It’s worth noting that Falcon 9 has faced challenges with its upper stage in recent years. In September 2024, during the Crew-9 mission, an upper stage issue caused it to reenter outside its intended zone. Following that incident, launches were temporarily halted until the FAA approved SpaceX’s investigation results. Similarly, in February 2025, a propellant leak led to another upper stage failing to deorbit, causing debris to land in Poland. However, that incident didn’t halt future launches.
Spaceflight expert Jonathan McDowell shared insights on February 2, pointing out that the upper stage from the latest launch is currently orbiting at around 110 by 241 kilometers. This low orbit suggests it will reenter the atmosphere soon.
Historically, SpaceX has had its share of setbacks, but it remains a leader in the commercial space arena. Customers and fans alike eagerly follow these developments, often sharing reactions on social media. The latest incident highlights both the challenges of space travel and the rigorous standards that companies like SpaceX uphold to ensure safety.
For those interested in the technical aspects of space operations, understanding these “off-nominal conditions” is crucial. They remind us that space flight is complex. Even with advanced technology, unexpected issues can arise, requiring careful analysis and immediate action.
