New Study Proposes Optimized Route to Mars, Reducing Travel Time to 153 Days
A recent study published in the journal Acta Astronautica suggests a new trajectory for traveling to Mars that could significantly reduce the journey time. Cosmologist Marcelo de Oliveira Souza from the State University of Northern Rio de Janeiro has calculated a route using the asteroid 2001 CA21, which could cut the travel time to Mars to just 153 days. This optimized path takes advantage of the asteroid's orbital plane, which crosses the orbits of both Earth and Mars at a five-degree tilt. The study highlights the 2031 Mars opposition as a particularly favorable time for this route, potentially allowing for two complete sub-year round-trip missions. Despite challenges such as propulsion methods and payload mass, this research offers a promising approach to making human-crewed missions to Mars more feasible.
