NASA's Swift telescope is falling out of orbit. A startup had nine months to save it.
The Neil Gehrels Swift Observatory has spent nearly 22 years detecting gamma-ray bursts, X-ray transients, and ultraviolet afterglows from low Earth orbit. It’s one of the most productive space telescopes ever launched — over 1,600 gamma-ray bursts catalogued, thousands of follow-up observations forwarded to ground-based telescopes within seconds. And it’s falling. No later than Tuesday, a refrigerator-sized spacecraft built by a startup in nine months will ride the last Pegasus XL rocket ever launched in an attempt to grab Swift, lock onto its structure with three robotic arms, and push it back up. If it works, it’ll be the first time anyone has docked with a satellite that was never designed for servicing. ...
