Solar Oberth Maneuver Could Put a Spacecraft on Track to Intercept Interstellar Comet 3I/ATLAS

Space.com reports a team proposes using a solar Oberth maneuver near 3.2 solar radii to launch a ~500 kg spacecraft in 2035, aided by a Jupiter gravity assist and heavy boosters, to perform a high-speed flyby of interstellar comet 3I/ATLAS by around 2085 at about 732 AU from the Sun. The interceptor would be heat-shielded and not intended to enter orbit, making it a close-proximity encounter rather than a rendezvous. While the concept is theoretically feasible and could push the boundaries of solar-system exploration, researchers note more practical, near-term approaches (like ESA’s Comet Interceptor) could target interstellar objects sooner.
