The Hohmann transfer orbit can be made free-return. It takes 250 days (0.68 years) in the transit to Mars, and in the case of a free-return style abort without the use of propulsion at Mars, 1.5 years to get back to Earth, at a total delta-v requirement of 3.34 km/s. Zubrin advocates a slightly faster transfer, that takes only 180 days to Mars ...
The ESA has also considered a sample return mission, one of the latest known as Martian Moon Sample Return or MMSR, and it may use heritage from an asteroid sample return mission. [57] Osiris-Rex 2 was a proposal to make OR a double mission, with the other one collecting samples from the two Mars moons. [58]
In October 2009, NASA and ESA established the Mars Exploration Joint Initiative to proceed with the ExoMars program, whose ultimate aim is the return of samples from Mars in the 2020s. [33] [34] ExoMars's first mission was planned to launch in 2018, [35] [36] with unspecified missions to return samples in the 2020–2022 time frame. [37]
A photomontage shows tubes containing samples from Mars, as collected by NASA's Perseverance Mars rover. The agency's Mars Sample Return Program plans to bring these samples back to study them in ...

The Soviet Union considered a Mars sample-return mission, Mars 5NM, in 1975 but it was cancelled due to the repeated failures of the N1 rocket that would have launched it. Another sample-return mission, Mars 5M (Mars-79), planned for 1979, was cancelled due to complexity and technical problems. [14]
Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...
The rover took 29 weeks to travel to Mars and made its landing in Jezero Crater on February 18, 2021, to begin its science phase. [78] After May 17, 2022, the rover will move uphill and examine rocks on the surface for evidence of past life on Mars. On its return downhill, it will collect sample rocks to be retrieved and examined by future ...
