The Swift space mission is experiencing difficulties due to failures in its reaction wheel system. Preliminary investigations reveal that two of the three reaction wheels are currently non-operational.
The issue centers around the Swift spacecraft, which utilizes reaction wheels for attitude control – maintaining its orientation in orbit. According to reports, “preliminary investigation shows that two of Link's three reaction wheels currently are not operable.” The source did not specify when the failures occurred or how they impacted mission operations.
Reaction wheels function by spinning a flywheel inside the spacecraft; changes in speed control the satellite’s orientation without needing propellant. Losing functionality in multiple wheels complicates maintaining stable pointing, which is crucial for Swift's observations. While the exact consequences of these failures are not detailed in the source material, it indicates challenges for the mission going forward.
The report does not offer details on potential solutions or timelines for repair, only stating that an investigation into the cause of the reaction wheel malfunctions is underway.
We don't rate truth. We strip the spin and show you which perspectives covered the story. You decide.
