To save this space telescope, a rocket will be launched from a plane

Launched in 2004, the Neil Gehrels Swift Observatory's mission is to observe and study gamma-ray bursts from its low orbit. However, over the past several years, its orbit has decreased from 600 km to 400 km, and it could crash into Earth at the end of 2026.

It must be said that NASA finds itself in a difficult situation. Swift does not have an engine, which prevents astronomers from making it perform various maneuvers remotely. As a result, a rescue mission has been ordered, and Pegasus, a rocket launched from Northrop Grumman's L-1011 Stargazer aircraft, will have to save it.

According to Ghonhee Lee, CEO of Katalyst, it is the only launcher capable of reaching Swift's orbit and meeting a very tight deadline. And this mission could end well, as Pegasus has completed 40 out of 45 missions since 1990 successfully. However, some modifications will be made to this launcher, and it will be longer and wider.

Thus, the rocket, named Pegasus XL, will be launched in June 2026 and will capture Swift using three robotic arms. But it will be necessary to avoid damaging the different instruments of this telescope and it will be crucial to handle it with caution.

As a result, if everything goes as planned, Swift will return to its original orbit, and will be able to continue conducting various studies. In addition, this would also be a success for Katalyst, which could carry out other missions in the future.
