NASA is preparing for a critical mission to prevent the Swift Observatory from crashing back to Earth. The $30 million operation will deploy a robotic spacecraft to elevate the observatory to a safer orbit. Launch preparations are underway, with Katalyst Space Technologies leading the mission.
Katalyst’s spacecraft, equipped with three mechanical arms, will pursue Swift after taking off from the Pacific’s Marshall Islands on a Pegasus rocket. The launch is anticipated as early as Tuesday. Since its 2004 launch, Swift has been pivotal in scanning the universe for significant explosions. However, increased solar activity has accelerated its descent, necessitating an urgent move to a more stable orbit.
The Hubble Space Telescope, also at risk, might be next in line for rescue. Like Swift, Hubble’s orbit is compromised by solar flares. Katalyst CEO Ghonhee Lee mentions that the company’s future robots could preserve Hubble in a few years, highlighting the mission’s importance for future satellite servicing.
Only China has conducted a similar mission, moving a satellite to a higher orbit four years ago. This marks the first American attempt of its kind. “NASA has several major observatories, and all could benefit from such services,” Lee noted, emphasizing the mission’s potential impact.
The autonomous spacecraft, called Link, will take about a month to align with Swift, and additional months to elevate it from 224 miles to 373 miles in orbit. The operation is crucial, with Swift’s critical altitude limit of 185 miles approaching soon.
“If Swift reenters, we lose the telescope and its capabilities,” said NASA’s science mission chief, Nicky Fox. “We can’t afford to build a replacement right now.”
Nine months after signing a rapid-deployment contract, Katalyst aimed to avoid worsening the situation while completing the mission. Shawn Domagal-Goldman, NASA’s astrophysics director, expressed optimism despite initial skepticism about success.
Nasa has paused Swift’s scientific work to slow its descent, hoping this mission will restart operations by September. The telescope, valued at hundreds of millions, was originally non-repairable, adding complexity to this endeavor.
If successful, Katalyst plans to expand space repair missions. The next-generation robot, scheduled for next year, will operate at altitudes of up to 22,300 miles, pointing to a future filled with possibilities for satellite maintenance and construction in orbit.
The Hubble Telescope may also benefit from these advancements by 2028, with Katalyst’s potential assistance extending its operational life. “It’s a national treasure,” said Fox, underlining its significance.
This mission sets a precedent for servicing NASA’s older space assets and may pave the way for robust in-space repair industries.
