Back in 2017, astronomers spotted something extraordinary — a mysterious object named ‘Oumuamua, the first known interstellar visitor to sweep through our Solar System. Its appearance sparked global excitement and ignited a new scientific quest: to catch and study these cosmic drifters.
These objects, likely ejected from faraway star systems, may carry chemical clues about alien worlds we’ve never seen. But intercepting one is no easy task. Interstellar objects (ISOs) move at breakneck speeds — ‘Oumuamua, for instance, zipped by at over 32 kilometers per second — and we typically notice them only after they’ve already slipped past Earth.
That’s about to change.
Space agencies like NASA and the European Space Agency (ESA) are preparing to act. ESA’s Comet Interceptor, slated for launch in 2029, will park in space, ready to rendezvous with a pristine comet — or, ideally, an ISO. NASA’s proposed Bridge mission would launch in rapid response to a new detection. And future efforts may use cutting-edge tech like solar sails, AI-driven navigation, and swarms of nimble spacecraft to make real-time interceptions possible.
Meanwhile, the upcoming Vera C. Rubin Observatory is set to revolutionize our sky-watching capabilities. Once active, it could detect dozens of ISOs each year, vastly increasing our chances to study these ancient travelers from other star systems.
But timing is everything. Without the right tools and consistent support, we could miss our chance. The race to catch an object from beyond the stars has begun — and it’s moving fast.
