The lowest energy transfer to Mars is a Hohmann transfer orbit, 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 has a reputation as a difficult space exploration target; just 25 of 55 missions through 2019, or 45.5%, have been fully successful, with a further three partially successful and partially failures. [citation needed] However, of the sixteen missions since 2001, twelve have been successful and eight of these remain operational.

The trip is expected to take nine months to a year with stops along the way to study the local terrain. [94] [95] [96] On 16 July 2013, the Curiosity rover reached a milestone in its journey across Mars, having traveled 1 km (0.62 mi), since its landing in 2012; [97] on 1 August 2013, the rover traveled over one mile: 1.686 km (1.048 mi).

The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history. Viking 1 operated on Mars for 2,307 days (over 6 1 ⁄ 4 years) or 2245 Martian solar days , the longest extraterrestrial surface mission until the record was broken by the Opportunity rover on May 19, 2010.
A NASA mission to test how living on Mars would stress and test a human crew ended Saturday, with four volunteers emerging from more than a year in a 1,700-square-foot structure.
A Mars to Stay mission following Aldrin's proposal would enlist astronauts in the following timeline: [11] Age 30: an offer to help settle Mars is extended to select pioneers; Age 30–35: training and social conditioning for long-duration isolation and time-delay communications; Age 35–65: development of sheltered underground living spaces
