Key actors — tap for context
NASA
The American space agency that operates the Swift telescope.
Why here: Commissioned and is overseeing the $30 million rescue mission.
More info →Katalyst Space Technologies
A private Arizona company focused on servicing satellites in orbit.
Why here: Built the LINK rescue ship and is carrying out the maneuver itself.
Swift
NASA's space telescope for observing gamma-ray bursts, officially the Neil Gehrels Swift Observatory, in orbit since 2004.
Why here: Is the object of the rescue — its orbit is decaying and it risks burning up in the atmosphere.
Northrop Grumman
An American defense and aerospace company.
Why here: Supplies the Pegasus XL rocket that will carry the LINK ship into orbit.

NASA launched the Swift telescope in 2004 into an orbit roughly 600 kilometers high. Over two decades it has dropped to approximately 370 kilometers — and the fall has unexpectedly accelerated. The Sun is to blame: in late 2024 and early 2025 it was more active than forecasts predicted, and its radiation heated and "puffed up" the upper layer of the atmosphere. Denser air at higher altitude means greater drag — and the satellite brakes faster. Science ↗According to estimates, Swift has a 50 percent chance of an uncontrolled reentry into the atmosphere by mid-2026, and up to a 90 percent chance by the end of that year. The telescope is still fully functional — which is precisely why NASA decided to rescue it rather than write it off. Astronomy ↗
A ship named LINK
The rescue is to be carried out by the LINK ship from the Arizona-based company Katalyst Space Technologies, which received a $30 million contract from NASA for it. The robotic module, weighing over 400 kilograms, is to approach the telescope and grab hold of it — it has three robotic arms for this purpose, and according to the company, a single successful capture is enough — and then fire its own ion (Hall-effect) thrusters to lift Swift into a higher, more stable orbit, safely above the roughly 300-kilometer threshold below which it would otherwise soon have dropped. Space.com ↗LINK will fly aboard a Pegasus XL rocket from Northrop Grumman — one that doesn't launch from a pad but is dropped by the L-1011 Stargazer aircraft at high altitude over the ocean. Engineers completed the integration of the rocket with the ship on June 9 at the Wallops facility in Virginia, from where it is traveling to the launch site in the Pacific. NASA ↗
Why it's a breakthrough
Satellite servicing missions usually take years of preparation. Katalyst and NASA managed to complete the entire project from contract signing to launch in roughly eight to nine months — pushed by the telescope's decaying orbit. "A completely unprecedented development schedule," said company representative Kieran Wilson; according to him, the goal was to launch before it was too late. SpaceNews ↗If the capture succeeds, it will be the first instance of a commercial ship capturing a government scientific satellite that was not built to be grabbed in space by anyone. Swift has no grapple points or interface surfaces that servicing ships normally rely on — LINK must latch onto the original structure in a way that does not damage the sensitive instruments.

The stakes and the risks
For NASA, this is also a test of a cheaper future. A $30 million repair is a fraction of the cost of a new instrument — Swift itself is estimated to be worth hundreds of millions. Spaceflight Now ↗The operation is nonetheless risky. Approaching and grabbing a slowly falling object that was never designed for it ranks among the hardest maneuvers in space; moreover, another wave of solar activity could accelerate the fall even further. If LINK fails or misses its launch window, Swift faces an uncontrolled reentry into the atmosphere — likely still this year. Science ↗
The story also has a broader dimension: it shows how orbital servicing — until recently the domain of science fiction and military programs — is turning into a commercial service. If Swift survives, it will open the way to extending the lifespans of expensive satellites instead of discarding them. If not, it will become another object that burns up falling to Earth.
