## Resource

By studying the trajectory of 2001 CA21, researchers uncovered orbital corridors that could enable round-trip missions to Mars in as little as 153 days—far shorter than traditional timelines. Instead of relying on new propulsion, the method optimizes interplanetary trajectory using natural orbital geometry. Shorter missions would reduce exposure to radiation and microgravity, making human travel more viable. The result reframes Mars as a far more accessible target for future exploration.
