NASA’s long-standing Swift Observatory, which plays a crucial role in monitoring the universe's most intense gamma-ray events, is currently drifting out of its orbital zone. In response, the U.S. space agency has enlisted an Arizona-based startup to implement a bold rescue plan before the telescope potentially faces uncontrolled reentry by late 2026.

Launched in 2004, the Neil Gehrels Swift Observatory has circled our planet for over two decades. However, increased solar activity has triggered greater atmospheric resistance, hastening its descent. To counter this, NASA has awarded Katalyst Space Technologies a substantial $30 million contract to provide aid to Swift through an innovative spacecraft known as LINK.

LINK is set for a challenging mission: it will autonomously approach the beleaguered observatory and adjust its position into a more stable orbit, thereby extending the operational lifespan of Swift's crucial gamma-ray burst observations. The team is racing against the clock, facing a launch deadline of June 2026—merely months away.

In a notably unconventional strategy, Katalyst intends to launch LINK using Northrop Grumman’s Pegasus rocket, an air-launched solution that deploys from an aircraft at 40,000 feet before igniting in midair to achieve orbit. This tactic was selected due to Swift’s specific inclinated orbit being much less suited to traditional ground launches, which are both inefficient and expensive.

Over time, Swift has gradually decreased in altitude, typical of most satellites. However, Katalyst warns that the current trajectory poses a 50% risk of uncontrolled reentry by mid-2026 and up to 90% by the year's end. While the telescope would likely disintegrate safely upon atmospheric reentry, the potential loss of its scientific legacy has led to this urgent rescue effort.

The Pegasus rocket, which has mostly lain dormant due to the rise of cheaper launch options, is making a comeback for this mission. “It intersects with our requirements for orbit, timing, and cost,” mentions Kieran Wilson, Katalyst’s technology VP.

If this mission succeeds, it could pave the way for future salvage operations targeting aging satellites, prolonging the lifespan of critical space assets while circumventing the need for costly replacements. The Swift Observatory's impending journey may very well demonstrate that creativity and technical prowess can indeed stave off catastrophe in space.
