Kornmesser\* A team of MIT researchers are suggesting that we could use a "dynamic orbital slingshot" to get an up-and-close look at interstellar objects — or, in other words, they want to send tiny satellites screaming through space to chase space rocks from beyond our star system. It's a far-out concept that's even grabbed the attention of NASA. The project has secured proof-of-concept funding from the NASA Innovative Advanced Concepts (NIAC) Program, an incubator for radically futuristic concepts such as turning a crater on the far side of the Moon into a [giant radio telescope](). Interstellar objects have been a fascinating and relatively recent addition to scientific inquiry. In particular, space rock [Oumuamua](), first spotted in 2017, and [2I/Borisov](), spotted by amateur astronomer Gennadiy Borisov last year, have puzzled astronomers due to their extremely unusual trajectories, leading them to believe they arrived from a neighboring star system. "There are a lot of fundamental challenges with observing \[interstellar objects\] from Earth — they are usually so small that light from the sun needs to illuminate it in a certain way for our telescopes to even detect it," said Richard Linares, assistant professor in the Department of Aeronautics and Astronautics (AeroAstro) at MIT who came up with the idea, in [a statement](). "They are traveling so fast that it’s hard to pull together and launch a mission from Earth in the small window of opportunity we have before it’s gone," Linares explained. "We’d have to get there fast, and current propulsion technologies are a limiting factor." To get over these limitations, Linares suggests using a series of "static satellites" that each use "solar sail" technology — using only radiation of the Sun as propulsion. ![]() This constellation of space buoys could then jump into action, releasing stored energy as well as using the gravitational pull of the sun to slingshot themselves after interstellar objects once they've been detected. But they won't attempt to stop when they get to these elusive extragalactic visitors. "Flyby missions tend to be easier because they don’t require you to slow down — you fly past the object and try to get as many pictures as you can in that window," Linares said. "Studying an interstellar body close-up would revolutionize our understanding of planet formation and evolution," professor of planetary sciences Benjamin Weiss, who is also working on the project, said in the statement. The slingshots could even allow us to study the feasibility of sending objects to other solar systems, according to Weiss. **READ MORE:** [Solar-sailing sentries could allow up-close study of interstellar visitors like 'Oumuamua]() \[*Space.com*\] **More on interstellar objects:** *[NASA: Something Is Off About This Interstellar Comet]()* ## 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]()
