NASA on Tuesday plans to launch a mission to save one of its workhorse space telescopes.<\/p>\n

For more than two decades, the agency\u2019s Neil Gehrels Swift Observatory has been circling Earth studying gamma-ray bursts, the most powerful explosions in the universe, which are triggered by events like births of black holes and collisions between ultra-dense stars at the ends of their lives. <\/p>\n

<\/div>\n

But Swift is at imminent risk of sinking back into the atmosphere, where it would break apart upon re-entry. NASA\u2019s prediction models suggest that the telescope\u2019s orbit could drop to an altitude considered critically low \u2014 below 185 miles \u2014 in October.<\/p>\n

\u201cIt is a swift observatory that can quickly pivot across the night sky to find things that go boom in the night,\u201d Dr. Shawn Domagal-Goldman, director of NASA\u2019s astrophysics division, said during a news conference on June 17, pausing to emphasize the pun with Swift\u2019s name. \u201cSo we decided, yeah, we want to go save this one this time because of how special it is.\u201d <\/p>\n

To stave off the observatory\u2019s demise, NASA plans to launch a robotic spacecraft to boost Swift\u2019s orbital path. The agency last year awarded a $30 million contract to the Arizona-based company Katalyst Space Technologies to build the spacecraft, with aerospace giant Northrop Grumman providing the plane and rocket that will send it into orbit. <\/p>\n

The plan calls for Northrop Grumman\u2019s Stargazer airplane to take off from the Marshall Islands no earlier than Tuesday at 6:23 a.m. Once it reaches 40,000 feet, the aircraft is expected to deploy the company\u2019s Pegasus XL rocket, carrying the 6-foot, 880-pound robotic spacecraft called LINK. <\/p>\n

<\/div>\n

The rocket should then launch LINK into orbit, where it would attempt to capture the Swift observatory and raise its orbit over a period of several months. <\/p>\n

All satellites in low-Earth orbit slowly lose altitude as they experience atmospheric drag. That process had affected Swift, but then came a period of intense solar activity in 2024, a phase in the sun\u2019s natural 11-year cycle known as solar maximum, which is characterized by increased flares and solar storms. When the sun\u2019s activity ramps up, it heats Earth\u2019s atmosphere, which increases drag on satellites in low-Earth orbit as they fly through \u201cthicker\u201d air, similar to the increased effort required to fly into strong headwinds.<\/p>\n

John Nousek, a professor of astronomy and astrophysics at Penn State University, said saving Swift could yield benefits beyond extending its time to conduct observations.<\/p>\n

\u201cIn addition to the scientific return, the new ability to retrieve a satellite (which was never planned to be serviced in orbit) will give NASA or other customers the capability to reuse, extend or add functions to existing spacecraft at a small fraction of the cost of a new mission,\u201d Nousek wrote in an email to NBC News. \u201cIf the LINK mission succeeds it will restore a $300 million (in 2004 dollars) satellite to full capability for only $30 million (in 2026 dollars).\u201d<\/p>\n

Kieran Wilson, vice president of technology at Katalyst Space Technologies, said he hopes the Swift Boost mission will change how astronomers think about satellites\u2019 lifespans.<\/p>\n

\u201cFor years and years, folks have thought about space as something where you build a satellite, you launch a satellite, it does its mission, and at the end of the mission, it gets disposed of, either it re-enters or it goes to a graveyard orbit at some point,\u201d he said during the June 17 news conference, adding, \u201cYou should be able to refuel, reposition, repurpose, repair, and even upgrade satellites, even if they were never prepared for it.\u201d<\/p>\n

<\/div>\n

NASA launched the Swift observatory in 2004 with an original mission duration of two years. The data Swift has gathered since then has helped scientists study more than 1,400 gamma-ray bursts and other high-energy events in the universe in stunning detail, including the most distant one ever detected, from an exploding star around 13 billion light-years away.<\/p>\n

NASA awarded Katalyst Space Technologies the contract to build and launch the LINK spacecraft in September 2025 \u2014\u00a0a tight turnaround. Although that timeline has been met, Wilson said, successfully meeting up with Swift in orbit and getting the satellite into a more stable orbit are still major undertakings. Swift was not designed to be serviced in space, so lacks onboard thrusters to raise its own orbit or rendezvous with another spacecraft. <\/p>\n

\u201cWe still have to operate the spacecraft there successfully, and as we\u2019ve all seen before, that\u2019s a very challenging thing to do,\u201d he said. \u201cRendezvous is going to be a challenge, it\u2019s always a technical challenge, but we think we\u2019re ready to handle that.\u201d<\/p>\n
