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.
