NASA Suspends Swift Observatory Operations to Mitigate Orbital Decay
NASA has temporarily halted most operations of the Swift Observatory to reduce atmospheric drag and slow its orbital decay, aiming to extend its mission ahead of a planned reboost.
NASA has temporarily suspended most science operations of the Neil Gehrels Swift Observatory to reduce atmospheric drag and slow the spacecraft's orbital decay. This measure aims to extend Swift's operational lifespan in anticipation of a planned reboost mission.
Launched in 2004, Swift has been instrumental in studying gamma-ray bursts, the universe's most powerful explosions. Over time, its low Earth orbit has gradually decayed due to atmospheric drag, a process accelerated by recent increases in solar activity. As of early February, the observatory's average altitude had fallen below approximately 250 miles (400 kilometers).
To address this, NASA has contracted Katalyst Space Technologies of Flagstaff, Arizona, to develop a mission that will boost Swift's orbit. The reboost mission is anticipated to launch in the summer of 2026. In the interim, by halting certain operations, NASA aims to maintain Swift's altitude above about 185 miles (300 kilometers), optimizing conditions for the upcoming reboost.
S. Bradley Cenko, the mission's principal investigator at NASA's Goddard Space Flight Center, stated,
"We anticipate the reboost mission to launch in the summer, so we're transitioning operations now to give it the best margin we possibly can."
This proactive approach underscores NASA's commitment to extending the scientific contributions of the Swift Observatory while pioneering new capabilities in satellite servicing.
