'Ice on Thruster': SpaceX Falcon 9 faces minor issue during Starlink satellite launch

Produced by: Tarun Mishra

Rare Incident

SpaceX's reliable Falcon 9 rocket faced an unusual anomaly during a mission to deploy Starlink internet satellites on Thursday night (July 11).

Launch Sequence

The Falcon 9 performed as planned initially, with its stages separating on schedule. The first stage successfully landed on a drone ship after liftoff from Vandenberg Space Force Base in California.

Upper Stage Issue

However, the rocket's upper stage, tasked with carrying 20 Starlink spacecraft into low Earth orbit, encountered a problem during its second burn.

Engine Failure

According to SpaceX CEO Elon Musk, the upper stage experienced a "rapid unscheduled disassembly" (RUD) during an attempted restart to raise perigee, the point closest to Earth in an orbit.

Satellite Deployment

Despite the anomaly, SpaceX managed to deploy the Starlink satellites, albeit into a lower-than-planned orbit.

Recovery Efforts

SpaceX is actively communicating with the deployed satellites to utilize their ion thrusters in an attempt to raise their orbits.

Technical Observations

During the flight, observers noted an unusual buildup of fluffy white material near the engine of the Falcon 9's upper stage, hinting at a potential propellant leak.

Falcon 9's History

The Falcon 9 rocket is renowned for its reliability, with numerous successful launches. This incident marks a rare setback, as the rocket has encountered only one full in-flight failure in its operational history.

Future Implications

It remains uncertain how this incident will impact SpaceX's upcoming launches and the Falcon 9's manifest. Engineers are currently analyzing data to determine the root cause and plan for future missions. This launch aimed to expand SpaceX's Starlink megaconstellation, which is crucial for global internet coverage, with ongoing efforts to increase the number of operational satellites.
