The robotic spacecraft sent to lift a falling NASA telescope has started tumbling during its own rescue mission.<\/p>\n

Two of LINK\u2019s three reaction wheels are not working, but power, communications, and main propulsion remain available, so the mission is not over.<\/p>\n

What was LINK sent to save?<\/h2>\n

NASA\u2019s Swift observatory has detected gamma-ray bursts and other violent cosmic events since 2004. Increased solar activity expanded Earth\u2019s upper atmosphere, increasing drag and lowering Swift\u2019s orbit faster than expected.<\/p>\n

NASA awarded Katalyst $30 million in September 2025 to raise the telescope. LINK was designed, built, tested, and launched in less than a year, reaching orbit on July 3, 2026.<\/p>\n

Why did the rescuer start spinning?<\/h2>\n

Katalyst said LINK spent roughly 72 hours in a multi-axis spin. Communications were temporarily lost and the spacecraft bus reset.<\/p>\n

Two of three reaction wheels, internal flywheels used to point a satellite, are non-functional. The small gas-thruster system used for fine control also has only partial functionality.<\/p>\n

The spacecraft is not dead<\/h2>\n

Electric propulsion, robotic systems, approach sensors, power, and communications are operating. LINK remains power positive and in contact with controllers.<\/p>\n

The team is using steerable electric thrusters to slow the spin. Its July 28 update said those burns had begun producing the intended effect.<\/p>\n

Can it still reach Swift?<\/h2>\n

After stopping the spin, engineers must rewrite guidance and control software for the remaining hardware. Ground tests would be followed by a move into a similar orbit and an inspection of Swift.<\/p>\n

Capture will be attempted only if LINK is healthy and the approach is safe. Officials say the mission remains active, not that success is assured.<\/p>\n

Why time matters<\/h2>\n

Swift suspended most science observations in February to reduce drag and preserve altitude. Every delay leaves less orbital margin for a capture attempt.<\/p>\n

This is the first planned commercial robotic capture of a government satellite never designed for servicing. It could open a new way to save aging spacecraft, but first the rescuer must stop spinning.<\/p>\n
