The announcement will take place at NASA headquarters in Washington, DC.
The new "roving laboratory" is the successor to the widely celebrated Curiosity rover.
The "roving laboratory" is powered by a radioisotrope generator that gives the rover an operating life-span of at least a full Martian year. This equals 687 days on Earth.
This is twice the average number of proposals submitted for similar competitions, and serves as an indicator of the public's prolific interest in exploring Mars, the space agency said.
