The nonprofit Planetary Society has laid out a detailed blueprint for sending astronauts to the Martian moon Phobos in 2033 and then touching down on Mars itself beginning in 2039.
The blueprint released Tuesday is based on a “Humans Orbiting Mars” workshopthat was conducted in April – and it’s probably already out of date, due to last month’s announcement that NASA’s first crewed flight of the Orion deep-space capsule is likely to be put off until 2023. Nevertheless, the Planetary Society’s Casey Dreier says the full study can serve as a realistic yardstick for NASA’s Mars exploration timetable.
