After making major contributions to our understanding of the cosmos for over 20 years, the observatory's orbit has been rapidly decaying, with the situation now terminal. By using a spacecraft designed and built by startup Katalyst Space Technologies, the space agency was hoping to nudge the observatory into a higher and more stable orbit. But the rushed mission [didn't achieve its lofty goal](), with Katalyst's spacecraft tumbling out of control months into its daring journey. Now, Swift is set to reenter the Earth's atmosphere in a matter of days, as [*Space.com* reports]() — and nobody knows where its remains will plummet down. According to an [October 23 update]() by the space agency, the observatory has started "to sink rapidly" thanks to an increase in atmospheric drag triggered by an eleventh-hour return to science observations. By mid-October, its orbit had reached just 171 miles, a point at which it was "no longer able to compensate for the effects of the increased drag." Swift is just one of countless objects on a trajectory to careen down through our planet's atmosphere. Experts expect most of the observatory to burn up, with only remnant pieces surviving the ordeal. "It is unfortunate that Swift was not 'reorbited,' but from a reentry hazard perspective it is a small portion of the stuff coming back in," LeoLabs senior technical fellow Darren McKnight told *Space.com*, adding that it's unlikely to pose a hazard to people back on the ground. Swift's deteriorating orbit also puts it only within roughly 21 degrees of the Earth's equator, which is predominantly open ocean. Accu Components aerospace parts supplier Accu Components quality manager Dean Sladen told *Space.com* that the telescope's "six heavy reaction wheels, the spinning flywheels it used to aim itself, along with tougher telescope parts such as lenses and mirrors" are most likely to survive reentry. While we won't have to worry about Swift causing damage on the surface, it's only one spacecraft's worth of space junk compared to the litany of debris making it through our planet's protective bubble. As the Earth's orbit becomes increasingly cluttered with space junk, the sheer amount of stuff that comes crashing down is [increasing year by year](), from [errant stages of Chinese rockets]() to [long-lost Soviet satellites](). **More on Swift:** [*NASA Telescope Careening Down to Earth After Failed Rescue Mission*]() ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]() ## More - [Elon Musk’s Neuralink Caught Filing for Benefits Meant for Small Businesses Run by Minorities]() - [The Trump Administration Reportedly Has Extensive Logs of Epstein Money Transfers, Refuses to Release Them]() - [Calm Down About the Area 51 Fire, People]() - [We Just Got a Major Clue About Why Twitter’s CEO Suddenly Left This Week]() - [Elon Musk Says He Is So Sorry for His Horrible Behavior]() - [United Airlines Shuts Down Starlink WiFi Service on Its Planes After the Antennae Caused Problems With Its Jets’ Equipment]() - [Hawk Tuah Girl Admits She Knew Essentially Zero About Crypto When Her Disastrous Meme Coin Launched]() - [Elon Musk Is Doing Business With Actual Terrorists, Nonprofit Finds]()
