The lowest energy transfer to Mars is a Hohmann transfer orbit, a conjunction class mission which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth.
The primary challenge with any mission to Mars is timing. Space agencies time their missions in windows when Mars and Earth are closest — roughly every 26 months — to save fuel and money.
Artist's conception of a human mission on the surface of Mars. 1989 painting by Les Bossinas of NASA's Lewis Research Center. A Space Launch System design in the 2010s. This rocket is envisioned as the launch vehicle for some of the latest NASA speculative long-term plans for Mars concepts, although there are some bold private venture plans that may also provide mass-to-orbit for any mission ...
Because of the proximity of the Mars moons to Mars, any mission to them may also be considered a mission to Mars from some perspectives. Past missions Three missions to land on Phobos have been launched; the Soviet Phobos program in the late 1980s saw the launch of Phobos 1 and Phobos 2 , while the Russian Fobos-Grunt sample return mission was ...
The SpaceX boss said the launch date is scheduled for when the next Earth-Mars transfer window opens in November 2026, which could see up to eight uncrewed Starhip missions to the Red Planet.
It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars .
The crew of a NASA mission to Mars emerged from their craft after a yearlong voyage that never left Earth. The four volunteer crew members spent more than 12 months inside NASA's first simulated ...
