NASA’s Neil Gehrels Swift Observatory, a 21-year-old space telescope that has tracked gamma-ray bursts and cosmic explosions since 2004, is losing altitude fast enough that the agency has suspended most of its science work and hired a private company to attempt an emergency orbit boost. The situation captures a tension that runs through much of NASA’s aging fleet, hardware built for a finite mission life keeps producing valuable science, but the physics of orbital decay does not negotiate extensions. What makes this case distinct is that NASA is betting on a small commercial firm, not an internal fix, to keep the telescope alive.
Why Swift Is Falling and What NASA Did About It
Swift was launched on November 20, 2004, into an orbit of roughly 584 by 601 kilometers with an inclination of about 20.6 degrees, according to historical mission documentation. That technical appendix anticipated that the orbit would remain high enough for safe operations until at least 2025, a projection that assumed a typical solar cycle and corresponding atmospheric density. Instead, a more active Sun has heated and puffed up the upper atmosphere, increasing drag on low-orbiting spacecraft. The extra resistance has been enough to erode Swift’s altitude faster than those early models expected.
NASA’s response has been to put science on hold to buy time. In a February 2026 update on a dedicated Swift mission blog, the agency explained that most observations were suspended and the spacecraft placed in a drag-minimizing configuration specifically to slow its descent while a reboost plan is prepared. When Swift slews rapidly between targets, its solar arrays and instruments present a larger area to the thin atmosphere, increasing drag; by parking the observatory in a more streamlined orientation, controllers can stretch its remaining lifetime. For astronomers who depend on Swift’s rapid-response capability, the pause means a temporary gap in data, but the mission team has framed it as a necessary trade to preserve the possibility of many more years of observations after an orbit raise.
A $30 Million Bet on Katalyst Space Technologies
Instead of designing a bespoke government-led servicing mission, NASA turned to a small company. In a February 11, 2026 announcement on its central news-release page, the agency said it had awarded Katalyst Space Technologies a $30 million Phase III Small Business Innovation Research contract to rendezvous with Swift and boost it to a safer altitude. NASA described the effort as a “race against the clock,” emphasizing that the observatory’s orbit is decaying quickly enough that the servicing vehicle must be designed, launched, and operated, on an aggressive schedule. The Phase III structure signals that this is not just an emergency rescue, but also a maturing of earlier technology work into a real operational capability.
The technical challenge is formidable for the relatively modest price tag. Swift was never designed to be serviced; it has no docking ring, no standardized grapple fixture, and no guidance markers optimized for a visiting vehicle. Katalyst will have to devise a way to approach and secure the spacecraft using only its existing external features, then apply controlled thrust without inducing damaging torques. The $30 million budget (roughly comparable to a single small launch) leaves little margin for elaborate robotics. If the company succeeds, it will demonstrate that commercial orbital servicing can extend the lives of unprepared legacy satellites at relatively low cost. If it fails, NASA loses both the money and Swift itself, underscoring the risk inherent in relying on a new entrant for such a high-stakes mission.
A Telescope That Keeps Breaking and Keeps Coming Back
Swift’s brush with orbital decay comes after a series of hardware scares that have already forced the mission team to improvise. On January 18, 2022, one of the spacecraft’s reaction wheels failed, pushing the observatory into safe mode while engineers assessed the damage. Rather than attempting a risky restart of the faulty wheel, NASA opted to reconfigure the spacecraft to operate with the remaining wheels, as described in a detailed mission status note. That solution restored pointing control but reduced redundancy, leaving less room for any future failures in the attitude-control system. It was an early sign that Swift was moving into a more fragile phase of its life.
More issues followed. According to a later update on NASA’s science portal, the observatory was again forced to suspend science operations after its gyroscopes showed signs of degradation. Engineers responded with a software patch that allowed Swift to operate with only two gyros, a configuration that restored observations on April 3, 2024 while accepting tighter operational limits. This sequence of failures and fixes shows both the ingenuity of the mission team and the narrowing margins of an aging spacecraft. Every workaround consumes redundancy and flexibility; the current pause for orbital reasons is not a reversal of the 2024 recovery, but the next chapter in a long running effort to keep a scientifically productive but increasingly fragile observatory working.
What Success or Failure Means Beyond Swift
Saving Swift is the immediate goal, but the implications reach much further. NASA operates a broad portfolio of satellites in low Earth orbit, many of which are delivering valuable science years or decades beyond their original design lifetimes. The agency’s main public site highlights missions ranging from astrophysics observatories to Earth-monitoring platforms, all of which will eventually confront the same orbital decay that now threatens Swift. A proven, relatively low-cost method for rendezvousing with and boosting old spacecraft would give program managers a new tool: instead of building replacements on fixed schedules, they could selectively extend the lives of high-performing assets, smoothing budgets and preserving unique data streams.
That broader context helps explain why NASA chose a Phase III SBIR contract that emphasizes commercial maturation. If Katalyst’s mission works, it could catalyze a market for orbital servicing vehicles that government and private operators alike might use. Future Earth-observing satellites, for example, might be designed with simple standardized features (reflective markers, grapple bars, or propellant interfaces) that make them easier for tugs to handle. Even spacecraft that were never designed for servicing, like Swift, could become candidates for life extension if the techniques proved on this mission are robust enough. In that sense, the observatory is both a scientific asset and a test case for a new way of managing space infrastructure.
Why Swift Still Matters for Science
Behind the engineering drama is a telescope that continues to play a central role in high-energy astrophysics. Swift was built to detect gamma-ray bursts, brief, intense flashes of high-energy radiation from distant galaxies, and to rapidly slew so its X-ray and optical instruments can capture the afterglow. Those observations help researchers study the deaths of massive stars, the mergers of neutron stars, and other extreme events. The observatory’s quick response has made it a cornerstone of so-called multimessenger astronomy, where gamma rays, X-rays, visible light, and sometimes gravitational waves are combined to build a fuller picture of cosmic explosions. Losing Swift prematurely would leave a gap that no single existing mission fully fills.
For non-specialists, the practical impact is less about any one burst and more about the cumulative record. Each event Swift logs adds to a long-term archive that scientists use to refine models of how heavy elements are forged, how black holes grow, and how the universe evolves. When NASA’s central news hub highlights discoveries about exotic cosmic phenomena, there is a good chance Swift data are in the mix. The current pause in observations slows the addition of new events to that archive, but if the orbit-boost mission succeeds, the payoff could be several more years of discoveries. The decision to trade short-term data loss for the possibility of a longer extended mission reflects a clear calculation: a few months of quiet now in exchange for preserving one of the most prolific burst-hunters ever flown.
