A three-armed spacecraft named Link, developed by Katalyst Space Technologies, launched from the Marshall Islands on Saturday to perform an orbital rescue of NASA’s Swift Observatory. The mission, valued at US$30 million, aims to boost the aging telescope’s altitude to prevent its atmospheric reentry, which is currently projected for October due to increased solar storm activity.
How does the Link spacecraft rescue mission work?
The Link spacecraft, launched via a Pegasus rocket from a modified airplane, is designed to rendezvous with the 1.4-metric tonne Swift Observatory. According to Katalyst Space Technologies, the spacecraft utilizes a three-armed capture mechanism to secure the telescope. Once attached, Link will fire its thrusters to slowly increase Swift’s altitude by 240km. This gentle approach is intended to avoid heavy jostling that could damage the sensitive scientific equipment onboard. The mission team completed the development of this salvage operation in nine months to meet NASA’s urgent recovery timeline.
The Swift Observatory has been tracking gamma-ray bursts and exploding stars since its launch in 2004. It is currently circling the Earth at an altitude of 360km.
Why is the Swift Observatory at risk of crashing?
Swift is losing altitude faster than anticipated because of increased atmospheric drag. This drag is a direct consequence of solar storms, which heat the Earth’s upper atmosphere and cause it to expand, creating more resistance for satellites in low Earth orbit. NASA suspended scientific observations to preserve the telescope’s orbit as long as possible. Without this intervention, the agency predicts the telescope will plunge to its demise in October.
Could this technology save other space assets?
NASA has identified the Hubble Space Telescope as a potential candidate for a similar salvage operation in a few years. Like Swift, Hubble is experiencing a decline in altitude due to atmospheric drag caused by the sun’s outbursts.
The commercial satellite servicing industry is rapidly evolving.
Frequently Asked Questions
When will the Swift Observatory return to normal operations?
If the rescue operation proceeds according to plan, NASA anticipates that Swift could resume scanning the cosmos by September.
Why did the launch face delays?
Katalyst Space Technologies reported that the mission faced a series of last-minute launch delays caused by a combination of technical issues and unfavorable weather conditions.
What is the primary risk of this mission?
Katalyst Space CEO Ghonhee Lee described the endeavor as a “high-risk, high-reward mission.” The primary danger was that the team would not launch anything and would let Swift burn up in the atmosphere.
