NASA’s plan to capture a falling telescope before it burns up in the atmosphere

After more than 20 years carrying out their work to perfectiona NASA space telescope is about to fall to Earth and burn up in its atmosphere. This would be very serious, both because of the possibility of uncontrolled debris being generated and because of the loss of the valuable work that this instrument is carrying out. For this reason, the US space agency has already teamed up with a private company to launch a ship into space capable of hunting the telescope and sending it to a safer orbit.

Key dates. The protagonist of this story is the Neil Gehrels Swift Observatory. According to the latest measurementscarried out in November 2025, there is a 50% risk that this telescope will leave its orbit and fall to Earth in June 2026. In addition, the risk rises to 90% before 2027. For this reason, NASA has granted $30 million to the company Katalyst to develop a robotic spacecraft capable of capturing the telescope and raising it to a safer orbit. The ship is called LINK and its development is going from strength to strength, although there is still no launch date.

The biter bit. Neil Gehrels Swift was sent to space in 2024 to capture and study the explosions of gamma rays. Since then it has provided very useful information; But unfortunately, this could change soon.

A subdued atmosphere. The problem lies in the attenuation of the Earth’s atmosphere. When we travel to space, this does not disappear suddenly, but rather fades little by little. Such a weak atmosphere has the ability to slow down spacecraft and send them into a lower orbit. If solar storms are added to this, capable of swelling the atmosphere, great aerodynamic resistance is produced. We are currently in a cycle of high solar activity, which reached its peak in October 2024. This possibly pushed the telescope to its limits, placing it in an unstable orbit, from which it could leave at any time.

Work against the clock. NASA and Katalyst are working around the clock to launch the LINK spacecraft on time. But in the meantime, the telescope must hold on. For this reason, some of its instruments have been turned off and their operations modified, in order to minimize their energy consumption. This has made it possible to reposition its solar panels and, thereby, reduce their resistance. Sooner or later this will not be enough, but at least it can buy some time until the LINK launch can take place.

In the absence of ground platforms, it is a good plane. In order to hunt this telescope in the orbit in which it is located, a launch configuration is necessary that is not available on any of the platforms available to NASA. Therefore, it is planned to launch the ship directly from an airplane. Thus, the trajectory can be adjusted much better. In short, this will be a unique event in history. A telescope has never been caught on the fly. For now we will have to wait, but we will be very attentive to the release dates.
