Scientists Say the Time Has Arrived to Land Astronauts on Mars

A consortium of American scientists and engineers released a report arguing that the time has come to send astronauts to Mars to search for life and answer whether humanity is alone in the universe. The 200-page document outlines eleven scientific objectives and recommends initial 30-day missions followed by extended 300-day stays, though major challenges remain including deep-space radiation exposure and biological contamination. While SpaceX's Elon Musk targets crew missions as early as 2029, scientists emphasize that human Mars exploration would represent the most significant space achievement since the Moon landing.
