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. [9] [10] This would be a 34-month trip.
Mars One states that "income from donations and merchandise have not been used to pay salaries". To date, no financial records have been released for public viewing. [84] Mars One initially estimated a one-way trip, excluding the cost of maintaining four astronauts on Mars until they die, at US$6 billion. [85]
Space activist Bruce Mackenzie, for example, proposed a one-way trip to Mars in a presentation "One Way to Mars – a Permanent Settlement on the First Mission" at the 1998 International Space Development Conference, [6] arguing that since the mission could be done with less difficulty and expense if the astronauts were not required to return ...
The mission was intended to be primarily a one-way trip to Mars. Astronaut applications were invited from the public all over the world, for a fee. The initial concept included an orbiter and small robotic lander in 2018, followed by a rover in 2020, and the base components in 2024. [127] The first crew of four astronauts was to land on Mars in ...

The Mars One Project is a privately-funded mission that will take 100 people to live on the Red Planet starting in 2026.
Crewed Mars rovers (also called manned Mars rovers [2]) are Mars rovers for transporting people on the planet Mars, and have been conceptualized as part of human missions to that planet. [ 3 ] [ 4 ] Two types of crewed Mars rovers are unpressurized for a crew in Mars space suits, and pressurized for the crew to work without a space suit.
A Mars return expedition may last two to three years [2] and may involve a crew of four to seven people, although shorter flyby missions of approximately 1 + 1 ⁄ 2 years with only two people have been proposed, [3] as well as one-way missions that include landing on Mars with no return trip planned.
