Mars 2020 is a Mars rover mission by NASA's
Mars Exploration Program with a planned
launch on 17 July 2020
and touch down in Jezero crater on Mars
on 18 February 2021
It will investigate an astrobiologically
relevant ancient environment on Mars and
investigate its surface geological processes and history
including the assessment of its past habitability
the possibility of past life on Mars
and the potential for preservation of
biosignatures within accessible geological materials
It will cache sample containers along its route
for a potential future Mars sample-return mission
The currently unnamed Mars 2020 mission was
announced by NASA on 4 December 2012 at the fall
meeting of the American Geophysical
Union in San Francisco
The rover's design is derived from the Curiosity rover
and will use many components
already fabricated and tested
including different scientific instruments and a core drill.
and a core drill.
NASA announced in June 2019 that a student
naming contest will be held in fall of 2019
to determine the name of the rover
The mission will seek signs of habitable
conditions on Mars in the ancient past
and will also search for evidence—or
biosignatures—of past microbial life
The rover is planned for launch in 2020 on
an Atlas V-541
and the Jet Propulsion Laboratory will
manage the mission
The mission is part of NASA's
Mars Exploration Program.
The Science Definition Team proposed that the rover
collect and package as many as 31 samples of
rock cores and surface soil for a later mission to
bring back for definitive analysis on Earth
In 2015 they expanded the concept
planning to collect even more samples and distribute the
tubes in small piles or caches across the
surface of Mars
In September 2013 NASA launched an Announcement
of Opportunity for researchers to propose and develop
the instruments needed
including the Sample Caching System
The science instruments for the mission were selected
in July 2014 after an open competition based on
the scientific objectives set one year earlier
The science conducted by the rover's instruments
will provide the context needed for detailed analyses
of the returned samples.
The chairman of the Science Definition Team stated
that NASA does not presume that life ever existed
on Mars
but given the recent Curiosity rover findings
past Martian life seems possible.
The Mars 2020 rover will explore a site likely to
have been habitable.
It will seek signs of past life
set aside a returnable cache with the most compelling
rock core and soil samples
and demonstrate technology needed for the
future human and robotic exploration of Mars.
A key mission requirement is that it must help
prepare NASA for its long-term Mars sample-return
mission and crewed mission efforts.
The rover will make measurements and technology
demonstrations to help designers of a future human
expedition understand any hazards posed
by Martian dust
and will test technology to produce a small amount of
pure oxygen from Martian atmospheric carbon dioxide .
Improved precision landing technology that enhances
the scientific value of robotic missions also will be
critical for eventual human exploration on the surface.
Based on input from the Science Definition Team
NASA defined the final objectives for the 2020 rover.
Those become the basis for soliciting proposals
to provide instruments for the rover's science
payload in the spring of 2014.
The mission will also attempt to identify
subsurface water
improve landing techniques, and characterize weather,
dust and other potential environmental conditions
that could affect future astronauts living and
working on Mars.
