The Facts

NASA and Katalyst Space announced on Wednesday that they are abandoning operations to boost the orbit of a failing observatory, citing ongoing attitude control issues that engineers were unable to resolve despite weeks of effort.
Katalyst Space
The Neil Gehrels Swift Observatory, launched in 2004 to study gamma-ray bursts and originally designed for a two-year prime mission, has become imperiled after its low Earth orbit began to degrade following more than 21 years of operations due to solar activity.
To rescue Swift, NASA partnered with Katalyst, awarding the company a $30 million contract to construct and launch LINK, a robotic spacecraft, to capture and boost the observatory's orbit before it could enter Earth's atmosphere.

However, soon after the spacecraft launched aboard a Northrop Grumman Pegasus XL rocket in July, LINK began spinning uncontrollably in orbit as hardware faults affected its orientation systems and engines, causing NASA and Katalyst to lose communication with it.

Despite Katalyst uploading new flight data, the two organizations concluded that persistent attitude problems made the original mission untenable. Instead, they stated they would test LINK's capabilities by attempting to conduct rendezvous and proximity operations with Swift.

Without a successful orbital boost, NASA expects Swift to re-enter Earth's atmosphere and burn up later this year. The agency said it will rely on other active observatories to help fill the gap in high-energy cosmic observations left by the telescope.

The Spin

Narrative A

The LINK mission falling short of its boost goal doesn't make it a failure. Rather, it has been genuinely valuable, with the operation laying the groundwork for future satellite servicing, as shown by Katalyst's and NASA's ability to move at an extraordinary pace to tackle a high-risk challenge, and the rendezvous data advances America's in-space capabilities.

Narrative B

Swift has delivered 21 years of groundbreaking science — including spotting the most powerful gamma-ray burst ever recorded — and losing it to an orbital decay that a working LINK could have prevented is a real blow. Framing this as a learning experience doesn't change the fact that irreplaceable capacity is now gone and a still-productive observatory has been lost.
