A unique NASA satellite is falling out of orbit—this team is trying to rescue it

BROOMFIELD, Colorado—One of NASA's oldest astronomy missions, the Neil Gehrels Swift Observatory, has been out of action for more than a month as scientists await the arrival of a pioneering robotic rescue mission. The 21-year-old spacecraft is falling out of orbit, and NASA officials believe it's worth saving—for the right price. Swift is not a flagship astronomy mission like Hubble or Webb, so there's no talk of sending astronauts or spending hundreds of millions of dollars on a rescue expedition. Hubble was upgraded by five space shuttle missions, and billionaire and commercial astronaut Jared Isaacman—now NASA's administrator—proposed a privately funded mission to service Hubble in 2022, but the agency rejected the idea. Swift may be a more suitable target for a first-of-a-kind commercial rescue mission. It has cost roughly $500 million (adjusted for inflation) to build, launch, and operate, but it is significantly less expensive than Hubble, so the consequences of a botched rescue would be far less severe. Last September, NASA awarded a company named Katalyst Space Technologies a $30 million contract to rapidly build and launch a commercial satellite to stabilize Swift's orbit and extend its mission.
