NASA is sending a robot to save a falling telescope. It has weeks to act.

The Neil Gehrels Swift Observatory has been hunting gamma-ray bursts since 2004. It was never designed to be serviced in orbit. NASA expected it to stay up until the early 2030s, but the current solar maximum has been more intense than predicted, heating Earth's upper atmosphere and increasing drag on low-orbit spacecraft more than the models anticipated. Swift is now on course to drop below a survivable altitude by October 2026.

So NASA hired a startup to rescue it.

Katalyst Space Technologies has built a small autonomous spacecraft called Link. The contract is worth $30 million. Link launched on June 30, 2026, and will spend roughly a month navigating to Swift's current orbit of about 360 kilometres altitude. It will then dock with the telescope, which was never built with a docking port, and spend another couple of months boosting it back up to around 600 kilometres, where atmospheric drag becomes manageable again.

There is no margin for error. Swift cannot fire its own engines; it has none. Link has to get there, grip a spacecraft it was never designed to grip, and push it accurately enough to extend Swift's life by years, not months.

"This is the first American space robot to go up and do anything like this," a NASA official told the Associated Press. That claim is accurate: robotic on-orbit servicing of a pre-existing spacecraft at this scale has not been done before in the United States.

If it works, the implications extend well beyond Swift. There are many satellites in low Earth orbit that will eventually lose altitude control. A proven commercial servicing capability changes the calculation for what is worth building and what is worth keeping.
