Finding fossils preserved from early Mars might tell us that life once flourished on this planet. We can search for evidence of cells preserved in rocks, or at a much smaller scale: compounds called biosignatures are molecular fossils, specific compounds that give some indication of the organisms that created them. However, over hundreds of millions of years these molecular fossils on Mars are subject to being destroyed or transformed to the point where they may no longer be recognized as biosignatures. Future missions must either find surface regions where erosion from wind-blown sand has recently exposed very ancient material, or alternately samples must be obtained from a shielded region beneath the surface. This latter approach is being taken by the ExoMars rover under development where drilled samples taken from a depth of up to 2 meters will be analyzed.

The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. Long-term proposals have included sending settlers and terraforming the planet. Proposals for human missions to Mars have come from agencies such as NASA, CNSA, the European Space Agency, Boeing, and SpaceX. Currently, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon, under the Apollo program.

Meanwhile, the uncrewed exploration of Mars has been a goal of national space programs for decades, and was first achieved in 1965 with the Mariner 4 flyby. Human missions to Mars have been part of science fiction since the 1880s, and more broadly, in fiction, Mars is a frequent target of exploration and settlement in books, graphic novels, and films. The concept of a Martian as something living on Mars is part of the fiction.

Several types of mission plans have been proposed, including opposition class and conjunction class,[5] or the Crocco flyby.[7] 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) at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth.[8][9] This would be a 34-month trip.

Shorter Mars mission plans have round-trip flight times of 400 to 450 days,[10] or under 15 months, but would require significantly higher energy. A fast Mars mission of 245 days (8.0 months) round trip could be possible with on-orbit staging.[11] In 2014, ballistic capture was proposed, which may reduce fuel cost and provide more flexible launch windows compared to the Hohmann.[12]

In the 1980s, it was suggested that aerobraking at Mars could reduce the mass required for a human Mars mission lifting off from Earth by as much as half.[15] As a result, Mars missions have designed interplanetary spacecraft and landers capable of aerobraking.[15]

When an expedition reaches Mars, braking is required to enter orbit. Two options are available: rockets or aerocapture. Aerocapture at Mars for human missions was studied in the 20th century.[16] In a review of 93 Mars studies, 24 used aerocapture for Mars or Earth return.[16] One of the considerations for using aerocapture on crewed missions is a limit on the maximum force experienced by the astronauts. The current scientific consensus is that 5 g, or five times Earth gravity, is the maximum allowable deceleration.[16]

Sterilizing human missions to this level is impossible, as humans are host to typically a hundred trillion (1014) microorganisms of thousands of species of the human microbiota, and these cannot be removed. Containment seems the only option, but it is a major challenge in the event of a hard landing (i.e. crash).[42] There have been several planetary workshops on this issue, but with no final guidelines for a way forward yet.[43] Human explorers would also be vulnerable to back contamination to Earth if they become carriers of microorganisms.[44]

Over the past seven decades, a wide variety of mission architectures have been proposed or studied for human spaceflights to Mars. These have included chemical, nuclear, and electric propulsion, as well as a wide variety of landing, living, and return methodologies.

A return mission from Mars will need to land a rocket to carry crew off the surface. Launch requirements mean that this rocket could be significantly smaller than an Earth-to-orbit rocket. Mars-to-orbit launch can also be achieved in single stage. Despite this, landing an ascent rocket on Mars will be difficult.[citation needed]

A person who is inactive for an extended period of time loses strength and muscle and bone mass. Spaceflight conditions are known to cause loss of bone mineral density in astronauts, increasing bone fracture risk. Last mathematical models predict 33% of astronauts will be at risk for osteoporosis during a human mission to Mars.[30] A resistive exercise device similar to ARED would be needed in the spaceship.

The rover Perseverance, which landed on Mars in 2021, is equipped with a device that allows it to collect rock samples to be returned at a later date by another mission.[73] Perseverance as part of the Mars 2020 mission was launched on top of an Atlas V rocket on 30 July 2020.[74]

Viking Mission to MarsNASA's Viking Mission to Mars was composed of two spacecraft,Viking 1 and Viking 2, each consisting of an orbiter and a lander.The primary mission objectives were to obtain high resolution imagesof the Martian surface, characterize the structure and composition ofthe atmosphere and surface, and search for evidence of life. Viking 1was launched on August 20, 1975 and arrived at Mars on June 19, 1976.The first month of orbit was devoted to imaging the surface to findappropriate landing sites for the Viking Landers. On July 20, 1976the Viking 1 Lander separated from the Orbiter and touched down at ChrysePlanitia (22.27 N, 312.05 E, planetocentric). Viking 2 was launched September 9, 1975and entered Mars orbit on August 7, 1976. The Viking 2 Lander toucheddown at Utopia Planitia (47.64 N, 134.29 E, planetocentric) on September 3, 1976. TheOrbiters imaged the entire surface of Mars at a resolution of 150 to300 meters, and selected areas at 8 meters. The lowest periapsisaltitude for both Orbiters was 300 km. The Viking 2 Orbiter was powereddown on July 25, 1978 after 706 orbits, and the Viking 1 Orbiter on August17, 1980, after over 1400 orbits. The Viking Landers transmittedimages of the surface, took surface samples and analyzed them forcomposition and signs of life, studied atmospheric composition andmeteorology, and deployed seismometers. The Viking 2 Lander endedcommunications on April 11, 1980, and the Viking 1 Lander on November 13,1982, after transmitting over 1400 images of the two sites. Many ofthese images are also available from NSSDCA online and as photographic products.

Further information on the spacecraft, experiments, and data returned from the Viking missions can be found in the September 30, 1977 issue of the Journal of Geophysical Research, "Scientific Results of the Viking Project", vol. 82, no. 28.

The NASA-funded Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) mission will launch in 2024. It consists of twin Mars orbiters that will answer deep questions about how the red planet's formerly thick atmosphere has been stripped away by solar radiation over time.

Russia's Phobos-Grunt sample return mission never left orbit due to a rocket failure, and eventually reentered Earth's atmosphere and crashed into the southern Pacific ocean. It was carrying The Planetary Society's LIFE experiment.

Phobos 2 was designed to orbit Mars and land a "hopper" and a lander on the surface of Phobos. The spacecraft successfully went into orbit and began sending back preliminary data. Then, on March 27, 1989, just before the spacecraft was to move within 50 meters of Phobos and deploy the two landers, the spacecraft's onboard computer malfunctioned and the mission was lost.

Phobos 1 was designed to study the Sun and interplanetary space while on its way to Mars. Once in orbit around Mars, it was going to study the red planet and take close-up images of its moon Phobos. However, on September 2, 1988, only two months into the flight, controllers on the ground accidentally uploaded software containing a command that deactivated the spacecraft's attitude control thrusters. The spacecraft then turned its solar panels away from the Sun and was unable to recharge its batteries. As a result, the mission was lost.
