There are both ready-to-launch spacecraft currently in storage on Earth, such as Janus, and spacecraft nearing the end of their missions at Mars. We calculate minimum \u2206V single-impulse direct transfer trajectories to 3I\/ATLAS both from Earth and from Mars. We consider launch dates spanning January 2025 through March 2026 to explore obtainable and hypothetical mission scenarios. Post-discovery Earth departures require a challenging \u2206V \u2273 24 km s\u22121 to fly by 3I\/ATLAS. By contrast, Mars departures from July 2025 &#8211; September 2025 require \u2206V \u223c 5 km s\u22121 to achieve an early October flyby &#8212; which is more feasible with existing propulsion capabilities. We discuss how existing spacecraft could be used to observe 3I\/ATLAS and how spacecraft at other locations in the Solar System could be repurposed to visit future interstellar objects on short notice.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Atsuhiro Yaginuma, Tessa Frincke, Darryl Z.
