NASA launches robotic mission to save space telescope from Earth re-entry

NASA has initiated a groundbreaking robotic mission to save its Swift space telescope from burning up upon re-entry into Earth's atmosphere. The Swift observatory, launched in 2004, is currently sinking faster than anticipated due to recent solar storms, increasing atmospheric drag.

The mission involves the launch of a three-armed spacecraft, Link, developed by Katalyst Space Technologies. Launched from the Marshall Islands aboard a Pegasus rocket, Link is designed to rendezvous with and capture the Swift telescope in approximately one month. This complex operation, expected to last several months, aims to boost Swift's orbit by 240 kilometers, returning it to a stable altitude.

This unprecedented effort comes at a cost of $30 million to NASA, with the goal of extending the telescope's operational life. Swift, which tracks major cosmic events like gamma-ray bursts and exploding stars, has had its observations put on hold to conserve its orbit. If the salvage is successful, Swift could resume its scientific work by September.

The success of this mission could set a precedent for future satellite life-extension services. NASA's Hubble Space Telescope is also experiencing a similar decline in altitude and could potentially be a candidate for a future salvage operation. Without this intervention, Swift is predicted to plunge to its demise in October.

This is a high-risk, high-reward mission. The biggest danger was always we don't launch anything and we let Swift burn up in the atmosphere. So we were always trying to avoid that risk, and our team has done that.
