4 days ago · NASA's human Mars exploration plans have evolved through the NASA Mars Design Reference Missions, a series of design studies for human exploration of Mars. In 2017, the focus of NASA shifted to a return to the Moon by 2024 with the Artemis program, a flight to Mars could follow after this project.
