The mission is timed for a launch opportunity in July/August 2020 when Earth and Mars are in good positions relative to each other for landing on Mars. That is, it takes less power to travel to Mars at this time, compared to other times when Earth and Mars are in different positions in their orbits. To keep mission costs and risks as low as possible, the Mars 2020 design is based on NASA's successful Mars Science Laboratory mission architecture, including its Curiosity rover and proven landing system.

It's hard to land on Mars, and even harder to land a rover close to its prime scientific target. Previous rovers have landed in the general vicinity of areas targeted for study, but precious weeks and months can be used up just traveling to a prime target. The Mars 2020 mission team is working on a strategy to put the rover on the ground closer to its prime target than was ever before possible. The Range Trigger technology reduces the size of the landing ellipse (an oval-shaped landing area target) by more than 50%. The smaller ellipse size allows the mission team to land at some sites where a larger ellipse would be too risky given they would include more hazards on the surface. That gives scientists access to more high priority sites with environments that could have supported past microbial life. More Information, landing sites Return
FINAL THREE LANDING SITES At the third landing site workshop for the Mars 2020 rover mission on Feb. 810, 2017, a team of scientists narrowed down the list of potential places where NASA's Mars 2020 rover may land. Three sites were selected to continue as landing site candidates: Columbia Hills, Gusev Crater: Home to Mars rover Spirit Jezero Crater: Wet and Dry and Wet Again NE Syrtis: Once Warm, and Wet Return
The mission takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a "cache" on the surface of Mars. A future mission could potentially return these samples to Earth. That would help scientists study the samples in laboratories with special room-sized equipment that would be too large to take to Mars. The mission also provides opportunities to gather knowledge and demonstrate technologies that address the challenges of future human expeditions to Mars. These include testing a method for producing oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing weather, dust, and other potential environmental conditions that could affect future astronauts living and working on Mars.

Mars 2020 will carry an entirely new subsystem to collect and prepare Martian rocks and soil samples that includes a coring drill on its arm and a rack of sample tubes. About 30 of these sample tubes will be deposited at select locations for return on a potential future sample-retrieval mission. In laboratories on Earth, specimens from Mars could be analyzed for evidence of past life on Mars and possible health hazards for future human missions. More Information Return

Mars Sample Return (MSR) is a proposed mission to return samples from the surface of Mars to Earth. The mission would use robotic systems and a Mars ascent rocket to collect and send samples of Martian rocks, soils and atmosphere to Earth for detailed chemical and physical analysis. The earliest date planned for MSR is 2026, although the exact launch date hasn’t been determined yet. Return
