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]
A free-return transfer orbit to Mars is also possible. As with the Moon, this option is mostly considered for crewed missions. Robert Zubrin, in his book The Case for Mars, discusses various trajectories to Mars for his mission design Mars Direct. The Hohmann transfer orbit can be made free-return.
The Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002. [2] [3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit. [1]
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]

The mission would last about 3.5 years, including cruise, mapping orbit, 7 days on the surface, and sample return cruise time. [1] The spacecraft would be powered by solar arrays . In August 2015, the ESA - Roscosmos working group on post- ExoMars cooperation, completed a joint study for a possible future Phobos Sample Return mission, and ...

SCIM was a sample return mission that would have used a free-return trajectory and aerogel to capture Mars dust and return it to Earth [17] (see also: the Stardust mission). MARVEL was an orbiter that would have searched for volcanism as well as analyzed various components of the Mars atmosphere. [17]
