Perseverance, nicknamed Percy, is a car-sized Mars rover designed to explore the Jezero crater on Mars as part of NASA's Mars 2020 mission.

Scientists have made the most precise measurements ever of Mars’ rotation, for the first time detecting how the planet wobbles due to the “sloshing” of its molten metal core.

Red Planet Day commemorates the launch of the Mariner 4 spacecraft on November 28, 1964 which was the first craft to ever reach Mars.

The delta deposits in Jezero crater contain sedimentary records of potentially habitable conditions on Mars, NASA’s Perseverance rover is exploring the Jezero western delta with a suite of instruments that include the RIMFAX ground penetrating radar, which provides continuous subsurface images that probe up to 20 meters below the rover.
