As of now, a first manned mission to Mars has not yet occurred. Various space agencies, including NASA, have proposed plans and timelines for such a mission, aiming to potentially send humans to Mars by the late 2020s or 2030s. These plans involve extensive preparation, including technological development, training astronauts, and conducting uncrewed missions to test the feasibility of sustaining human life on the Martian surface. The complexities of such a mission, including long-duration space travel and life support systems, make it a crucial area of research in space exploration, and significant advancements are anticipated in the near future.
