NASA says Swift orbit-boost attempt ended without a boost
NASA says LINK did not raise the Neil Gehrels Swift Observatory’s orbit after the servicing spacecraft developed intermittent communications and orientation-control problems. NASA and Katalyst scaled the mission back from a grapple-and-boost attempt to technology demonstrations. NASA had forecast that Swift would re-enter the atmosphere by the end of 2026 without intervention; its controllers also suspended pointed science observations for several months while using lower-drag pointing to keep the observatory above a critical altitude. NASA says the work generated operational experience, but detailed technical results and independent confirmation were not supplied. [1]

NASA says its attempt with Katalyst Space to raise the Neil Gehrels Swift Observatory’s orbit ended without a boost. The agency reports that communications losses and orientation-control issues aboard Katalyst’s LINK spacecraft led the teams to abandon the planned grapple-and-boost operation. NASA had said that, without intervention, Swift was expected to re-enter Earth’s atmosphere by the end of 2026 as its mission approached its close. [1]

Why the boost plan changed
NASA reports that the orbit raise was not completed. The supplied account says LINK’s revised task was to attempt demonstrations rather than capture Swift, but it does not specify which demonstrations succeeded or provide measured results. [1]
- NASA contracted Katalyst Space in September 2025 for a compressed mission to design, build, test, launch, rendezvous with, grapple, and lift Swift. [1]
- After reaching space and completing initial checkouts, LINK experienced intermittent communications losses and orientation-control issues, according to NASA. [1]
- NASA says the partners then agreed to stop pursuing the grapple-and-boost objective and instead attempt technology demonstrations involving LINK’s xenon-powered propulsion and three robotic arms. [1]
04
What the result meant for Swift
NASA presented the boost effort as a time-critical attempt to extend Swift’s time in low Earth orbit. Because the planned orbit raise did not occur, NASA’s forecast of re-entry by year’s end remained important context, although the supplied material provides no later outcome for Swift itself. [1]
- NASA says Swift was predicted to descend to roughly 300 kilometres, described as a point of no return for the boost attempt, in fall 2026. [1]
- The agency also said that, without intervention, Swift was expected to re-enter the atmosphere by the end of 2026. [1]
- NASA formally ended its involvement in LINK’s mission on September 3, 2026, and records that LINK re-entered the atmosphere on September 25, 2026. [1]
05
How controllers bought time
NASA says the operations team had to reduce atmospheric drag while avoiding pointing directions near Earth, the Moon, or the Sun that could overheat or damage instruments. It also reports that a streamlined orientation could expose the telescopes to atmospheric particles. NASA says the resulting balance bought time for the boost effort, but did not produce an orbit raise. [1]
- NASA says controllers began replacing about 25% of Swift’s normal science targets with lower-drag pointing directions in December 2025. [1]
- By February 2026, the controllers had moved entirely to the drag-reduction approach. [1]
- NASA reports that Swift was not executing pointed science observations from mid-February through late August. [1]
- NASA says the approach kept the observatory above the critical altitude threshold for several months. [1]
06
What NASA says the teams learned
NASA records the effort as a source of experience for future servicing programmes, despite the failed boost. This is an agency assessment: the supplied evidence does not independently establish the performance of the demonstrations or their eventual effect on later missions. [1]
- NASA says the work provided operational experience in a rapid, high-risk servicing effort. [1]
- The agency identifies experience with LINK’s propulsion system and robotic arms as relevant to possible future in-space servicing. [1]
- NASA also describes the mission as a test of faster project management and satellite operations intended to extend time in low Earth orbit. [1]

Limits of this edition
This brief is based on one primary NASA article; no independent reporting or technical post-mission report was supplied. [1]
NASA does not provide detailed telemetry, a full anomaly investigation, or quantified results for LINK’s technology demonstrations. [1]
NASA describes the experience as useful for future spacecraft-servicing work. That prospective value is the agency’s assessment, not independently established impact. [1]
The supplied evidence establishes no concrete Armenia-specific effect or participation path. [1]
