NASA robot launches to rescue falling telescope
NASA has launched a robotic mission to catch a falling telescope in orbit and boost it to safety, a first-of-its-kind operation.
The update
NASA has dispatched a three-armed spacecraft to catch a falling telescope in mid-orbit. The mission, launched on Friday from the Marshall Islands, aims to prevent the Swift observatory from burning up in Earth’s atmosphere.
The spacecraft, built by Katalyst Space Technologies, must locate Swift, dock using its robotic arms, and then push it back to a higher, stable orbit. The operation is expected to take several months and has never been attempted before.
Why it matters
Swift is a specialized tool for studying gamma-ray bursts, the most powerful explosions in the universe. It is the only telescope capable of observing these events in real time.
Unlike typical satellites that burn up on re-entry, Swift is considered too valuable to lose. The mission could also set a precedent for rescuing other aging satellites, potentially saving billions of dollars of hardware.
What to watch
Success is not guaranteed. The mission involves complex maneuvers in the vastness of space, and the telescope is currently descending faster due to increased solar activity.
Observers will be watching for the spacecraft to reach Swift’s orbit and perform the capture maneuver. If successful, it could pave the way for future satellite rescues.
