Saving Swift: How Robotics May Rescue NASA's First Responder

Updated: Jun 22

Saving The Swift Observatory

During a media event at NASA’s Wallops Flight Facility on June 17th, 2026 the teams from across NASA, Katalyst Space and Northrop Grumman came together to discuss the challenges and accomplishments surrounding the critical and time sensitive mission to save the $500 million dollar Neil Gehrels Swift Observatory from a decaying orbit.


What makes this observatory unique? Swift was built to hunt some of the universe’s most powerful explosions: gamma-ray bursts. It is able to rapidly reposition toward new targets, often within minutes, while observatories like Hubble and James Webb may require days. This agility has earned it a reputation as astronomy’s first responder. This is one of the reasons NASA has chosen to continue Swift's mission to search out those things that go boom in the night, and that night is long, vast and old as time itself.


Launched in 2004 and only expected to last for a mission of two years, it has been continuously providing valuable astronomical observational information about deep space for over 21 years, which also means its orbit has decayed significantly over that duration. NASA has chosen to expand its lifespan by boosting it from a decaying orbit, but they had to move quickly.


Predictions estimate Swift may fall below 300km sometime around October, at which time it will be considered too low for recovery and is why timing is critical for this boost to occur well before then. Modeling is impacted by events like solar weather and insufficient measurements of Earths own atmosphere, which contribute to this uncertainty. Swift continues to fall at a rate of 8km per month and its rate of descent will increase as it gets lower. Rendezvous will be challenging for this rescue mission, but this team has been working tirelessly through these complicated scenarios.


Assembling the A-Team

No one thought we would get this far,” remarked Shawn Domagal-Goldman, Division Director of Astrophysics at NASA Headquarters in Washington as he recalls how quickly they had to move. Timing was everything. This team had under eight months to prepare a rescue operation to save Swift on a budget of $30 million. Here we stand today, viewing the fully integrated Pegasus XL rocket with the LINK robotic system aboard the Northrop Grumman L-1011 Stargazer aircraft.  


One thing is clear, they are proud of how the teams across agency and commercial partnerships came together with a spirit of mentorship rather than oversight, which was critical to delivering such a complex project within an accelerated timeline.

Getting Us There

Northrop Grumman's Stargazer-Pegasus launch system is a unique airborne launch platform that provides rapid-response access to space from locations around the globe. For this mission, the aircraft is expected to depart from Kwajalein Atoll in the Marshall Islands, with a mid-air launch targeted no earlier than June 27.


Unlike traditional rockets that launch from a fixed pad, the Pegasus XL rocket is carried beneath the Stargazer aircraft and released in flight at a predetermined location optimized for orbital insertion. After climbing to approximately 40,000 feet, the aircraft releases Pegasus, which ignites its first-stage motor seconds later and begins its journey to orbit. This air-launch capability offers significant flexibility, allowing missions to launch from a variety of locations worldwide while reducing many of the constraints associated with ground-based launch sites.


Following launch, LINK is expected to rendezvous with NASA's Neil Gehrels Swift Observatory approximately four weeks later. A detailed inspection and survey phase will precede capture operations, which are anticipated to occur. Once securely attached, LINK will perform a series of maneuvers to raise Swift's orbit to a target altitude of approximately 550 kilometers, extending the observatory's operational lifetime. To maximize the spacecraft's chances of success, NASA has temporarily suspended Swift's science operations in an effort to minimize atmospheric drag and preserve orbital altitude ahead of the rescue mission.


This mission will hopefully demonstrate the capability to utilize robotics to capture and service un-crewed spacecraft that have not been designed for servicing of this nature.

Dynamic Space Operations

With the future of space and exploration ever expanding, it is only sensible that we have an answer to how we will continue to maintain that presence if not also be able to build on it. The answer lies in robotics.


The robotics portion of this mission aims to change how people think about space. Having robotic servicing a viable option not only makes sense, but it is also necessary for dynamic space operations which is where our future lies.


Robotics can make docking routine and safe. Robert Lamontagne, Vice President, Strategic Partnerships at Katalyst Space even spoke of how eventually, he could envision a fleet of robotic service vehicles spanning in the hundreds operational and able expand the capability of what is possible for humanity to achieve in space.


Lamontagne states Katalyst will “do amazing things for America and provide more options both for the US government as well as for our commercial partners across the globe.” by marking the end of the era where satellites are a throw-away item, now wanting to “refuel, reposition, repurpose, repair, upgrade." satellites in space.  Their visions pave new and exciting roads for America’s future in space.


As cornerstone observatories like the Hubble Space Telescope continue to age, and significant investments are made in next-generation missions such as the Nancy Grace Roman Space Telescope and the future Habitable Worlds Observatory, developing robotic servicing capabilities will become increasingly important. These technologies could enable repairs, maintenance, and upgrades in orbit, extending the operational lifetimes of these valuable assets and ensuring they continue to deepen our understanding of the universe.


A Parting Gift

As a parting gift leaving Wallops in the early hours to drive back to the airport, the cosmos bid me farewell with a stunning alignment of the Milky Way galactic core positioned vertically over the Assateague Lighthouse standing guard on Assateague Island near Wallops Flight Facility, shining brightly 154 feet above sea level.


With the light swinging by every three seconds, timing was critical to avoid the glare in the camera lens. The shutter could only be left open for approximately two seconds, which also meant an incredibly high ISO of 10,000 and an f-stop of 1.4 on the Sigma 20mm lens to be able to capture the core. Not an ideal scenario for Milky Way imaging, but the scene was too inviting to pass by. To help improve the signal to noise ratio, thirty images were taken then stacked together in AutoStakkert.


This is just one example of what an amazing and beautiful universe we occupy and why efforts must prevail for its continued exploration. Even as novice astronomers, we can learn so much just by watching the night sky. Imagine what more we will learn from Swift and future missions like the Roman Space Telescope and maybe even the Habitable Worlds Observatory... what else is out there?
