A Proposed Mars Shortcut Points to a Faster Deep-Space Route
Using early orbital predictions for asteroid 2001 CA21, a researcher identified a possible Mars mission profile that could cut total round-trip travel time to roughly 153 days during a favorable 2031 window.
- A study used asteroid 2001 CA21's early orbital predictions to search for a faster Mars route.
- The analysis found a favorable launch geometry only in 2031.
