NASA is collaborating with Katalyst Space to rescue the Neil Gehrels Swift Observatory from a premature demise. The observatory, designed to study gamma-ray bursts, is descending towards Earth faster than expected and may disintegrate in the atmosphere by year’s end instead of lasting until 2030. To counter this, a robotic spacecraft is being developed to push Swift back into a higher orbit, potentially extending its operational lifespan by several decades.
Brad Cenko, the principal investigator of Swift, highlighted the urgency of the situation, noting that NASA typically takes decades to plan missions of this magnitude but managed to put this plan together in just over a year. The unexpected acceleration of Swift towards Earth’s orbit was attributed to heightened solar activity, coinciding with increased sightings of the Northern Lights.
The rescue mission involves a robotic spacecraft called LINK, which will be deployed using a rocket named Pegasus XL attached to the Stargazer airplane. The goal is for LINK to intercept Swift in space and utilize its robotic arms to push the observatory back into a stable orbit. This complex operation is set to unfold over a two-month period.
If successful, this mission could revolutionize in-space maintenance and pave the way for future endeavors such as refueling spacecraft, replacing components, and assembling telescopes in orbit. Mason Peck, a mechanical and aerospace engineering professor at Cornell University, emphasized the significance of this mission in advancing in-space servicing capabilities and promoting sustainability in Earth’s orbit operations.
Despite the risks involved, Cenko emphasized the valuable lessons that can be learned from this endeavor, regardless of the outcome, in terms of expediting mission planning and execution. The potential loss of Swift, a critical asset for studying cosmic phenomena, underscores the importance of innovative approaches to space operations and maintenance.
