For those that are wondering:
> The agency’s **Neil Gehrels Swift Observatory** is at risk of falling into the atmosphere. A spacecraft set to launch Tuesday is tasked with pushing the satellite back into a stable orbit.
Astronomer here! Worth noting that the satellite here, [Swift](https://en.wikipedia.org/wiki/Neil_Gehrels_Swift_Observatory), is actually *the* most cited and successful of all the NASA space telescopes. (Nope, not Hubble- by any research measurement Swift wins!) The reason is it’s designed to get on new gamma-ray bursts (GRBs) FAST- like, within minutes- but then it also has an X-ray instrument and UV telescope on board to pinpoint locations quickly. And when there *isn’t* a GRB going off, which is most of the time (say you discover a supernova, or a flare star begins to act up, etc), if you need a shallow observation of something you can get time on Swift without much trouble.
Despite this it of course has no equivalent and WILL burn up in the next few years in the atmosphere if nothing is done to save it, as it’s 20+ years old and out of fuel to go into a higher orbit. So if this works it is so cool, but also hopefully could be used for other satellites in the future. Fingers crossed!
