NASA is searching for options for a option to elevate the orbit of the Neil Gehrels Swift Observatory regardless of the spacecraft being marked for termination after FY2026 beneath the company’s finances proposal.
The potential impending demise of the spacecraft, coupled with faster-than-expected orbital decay as a result of further atmospheric drag attributable to photo voltaic exercise, makes Swift a really perfect candidate for the potential project.
NASA has chosen two American firms – Cambrian Works of Reston, Virginia, and Katalyst Area Applied sciences of Flagstaff, Arizona – to develop idea design research for a potential orbit increase. That mentioned, the company would not have agency plans for a reboost and will nonetheless enable the spacecraft to re-enter the Earth’s environment, “as many satellites do on the finish of their lifetimes.”
A lift may lengthen Swift’s lifetime, though the probe, which was launched in 2004 on a deliberate two-year mission, is exhibiting indicators of age. Final yr, the spacecraft dropped into safe mode after certainly one of its three remaining gyroscopes started exhibiting indicators of degradation. Engineers had been in a position to maintain the science flowing by implementing a plan developed in 2009 to function utilizing simply two gyros. The gyros are required to make sure Swift is pointed accurately.
Nevertheless, engineers do not need an answer for the growing atmospheric drag that can finally consequence within the spacecraft re-entering the Earth’s environment the place it is going to be destroyed. Nor have they got an answer for the potential https://www.theregister.com/2025/04/14/nasa_science_budget/”>budget cuts [PDF] that result in the end of operations after FY2026.
“NASA Science is dedicated to leveraging business applied sciences to search out progressive, cost-effective methods to open new capabilities for the way forward for the American area sector,” mentioned Nicky Fox, affiliate administrator, Science Mission Directorate, NASA Headquarters in Washington. “To take care of Swift’s position in our portfolio, NASA Science is uniquely positioned to conduct a uncommon in-space know-how demonstration to boost the satellite tv for pc’s orbit and solidify American management in spacecraft servicing.”
There are present choices for spacecraft servicing. Northrop Grumman, for instance, has its Mission Extension Automobile (MEV), which was used to increase the lifetime of an Intelsat Satellite tv for pc.
Swift is a three-telescope observatory for finding out gamma-ray bursts. The principal investigator for the mission was Neil Gehrels, for whom the mission was named after his dying.
NASA has different spacecraft that may profit from a reboost to increase their helpful lives. The Hubble Area Telescope springs to thoughts, a rescue of which was proposed by former NASA administrator nominee, Jared Isaacman, however was finally rejected. If Swift might be saved, then maybe the Hubble might be subsequent in line?
The Register requested NASA if this was a risk, in addition to how a lot time remained for a reboost of Swift.
In a press release, a A NASA spokesperson mentioned that Swift would seemingly enter the Earth’s environment by late 2026 as a result of elevated photo voltaic exercise. “NASA regularly tracks Swift to enhance estimates of its orbital decay.”
The spokesperson was unable to touch upon the FY2026 finances – it has but to be enacted – nevertheless they mentioned, “NASA is dedicated to advancing the event of key business capabilities for the USA, and takeaways from these idea research will assist inform company discussions about the way forward for its area telescopes.
“There’s time for the company to think about a fair broader set of economic options for a possible Hubble increase, and the vary of technical options would even be broader, as Hubble was designed to be serviced.” ®
