The Neil Gehrels Swift Observatory, a key tool for studying powerful cosmic events like gamma-ray bursts, has temporarily paused most of its scientific work. This measure is being taken to help the 21-year-old spacecraft slow its descent in orbit, a move intended to buy time for an upcoming mission to boost it into a higher, more stable path. This action also serves as a test for a new commercial capability to service satellites in space.
Background of the Swift Observatory
Launched in 2004, the Swift Observatory has been a workhorse in astrophysics, exceeding its initial two-year mission scope. Its primary function is to detect and study gamma-ray bursts (GRBs), the most powerful explosions in the universe. Upon detecting a GRB, Swift quickly relays the location to ground and space-based telescopes, enabling further observation of the event's afterglow. The observatory was designed to operate with its initial orbit of approximately 324 nautical miles (about 521 kilometers).

The observatory is managed by NASA's Goddard Space Flight Center and involves international collaboration.
Key partners include Penn State University, Los Alamos National Laboratory, and Northrop Grumman Space Systems.
Swift uses gyroscopes to point and maintain its orientation for observations.
Recent Operational Status and Challenges
In March 2024, Swift entered a "safe mode," suspending science operations due to a problem with one of its three gyroscopes. Although the spacecraft could function with only two gyroscopes, a software update was necessary to enable continued science observations.
A software update was successfully implemented, and Swift resumed science operations on April 3, 2024.
However, the underlying issue of orbital decay due to atmospheric drag persisted.
Transition to Orbit Preservation
As of February 11, 2026, NASA has again suspended most of Swift's science operations. This decision is a proactive measure to minimize atmospheric drag.

By orienting the spacecraft in a way that reduces drag, controllers aim to extend its time in orbit.
This period of reduced activity is critical to prepare for a planned "reboost" mission.
The Reboost Mission: A Commercial Endeavor
Instead of allowing Swift to naturally re-enter Earth's atmosphere, NASA has contracted Katalyst Space Technologies, an Arizona-based company, to perform an orbit-raising maneuver. This mission represents a significant step in developing commercial capabilities for in-space servicing.
The reboost mission is slated for a June 1, 2026, launch.
Katalyst's robotic spacecraft will autonomously approach, capture, and reposition Swift into a higher orbit.
This will be the first time a commercial robotic spacecraft captures an uncrewed government satellite not designed for servicing.
The total cost of this mission is approximately $30 million.
NASA is also exploring options with other companies, such as Cambrian Works and Starfish Space, for concept studies related to orbit boosts.
Significance of the Reboost Mission
The Swift reboost mission is seen as a pivotal demonstration of emerging technologies with implications beyond just extending Swift's life.
Scientific Extension and National Security
Extending Swift's scientific output allows it to continue its valuable observations of the universe.
The mission is also of interest to the Defense Department, showcasing capabilities for "tactically responsive space" and sustained maneuverability.
Satellite servicing capabilities are increasingly vital for national security, offering potential responses to space-based threats.
Technological Advancement
Successfully boosting Swift would demonstrate multiuse, commercially developed technology for the space domain.
This endeavor could establish a blueprint for future life extension of spacecraft in low Earth orbit.
It highlights the growing importance of on-orbit servicing, particularly for aging but productive satellites.
Potential Outcomes
The reboost mission carries both potential rewards and risks.

Success: Swift's operational life will be significantly extended, and a vital new commercial space capability will be proven.
Failure: If the Katalyst mission encounters issues, Swift would likely re-enter Earth's atmosphere as it would have without the reboost.
Expert Perspectives
"NASA's decision to pursue the reboost effort is commendable. If successful, it not only saves a valuable science asset but also pioneers a critical new space capability for the nation."— Unnamed scientist involved with Swift (paraphrased from Article 2)
"This reboost would demonstrate an emerging multiuse, commercially developed technology for the space domain—several technologies, actually."— Aviation Week Network report (Article 4)
Conclusion
The Neil Gehrels Swift Observatory is at a critical juncture. By temporarily halting science operations, NASA is prioritizing the spacecraft's long-term survival and the development of a pioneering commercial space servicing capability. The upcoming reboost mission by Katalyst Space Technologies is a high-stakes endeavor, promising to extend Swift's scientific legacy while forging a new path for in-space infrastructure and national security. The success or failure of this mission will offer valuable insights into the future of satellite servicing and the longevity of space-based assets.
