A researcher may have found a shortcut to Mars as NASA eyes red planet

Key Points:

• Under current conditions, a round trip from Earth to Mars takes about three years, due to the planets' orbital alignment occurring roughly every 26 months, with travel times of seven to 10 months one-way during optimal windows.
• Researcher Marcelo de Oliveira Souza discovered a potential shortcut to Mars by analyzing the orbital paths of near-Earth asteroids, proposing trajectories that could reduce round-trip travel time to less than a year, specifically around 153 to 226 days.
• Souza's proposed trajectories, based on the asteroid 2001 CA21's orbit, could be viable around 2031, but would require spacecraft to travel at speeds beyond current rocket and landing technology capabilities.
• NASA is actively preparing for human missions to Mars, using the Artemis lunar program to develop deep space travel capabilities, and plans to launch a nuclear-powered spacecraft to Mars in 2028 to test technologies crucial for future crewed missions.
• The nuclear-powered Space Reactor-1 spacecraft aims to arrive at Mars in 2030, deploying helicopters to scout landing sites and detect underground water, addressing challenges like dust storms that hinder solar power reliability on Mars.
