What is Red Planet Day?
Red Planet Day on November 28 marks the launch of NASA's Mariner 4 in 1964, the first spacecraft to fly past Mars successfully. In July 1965 it sent back the first close-up pictures of another planet, showing a cratered, dry surface rather than the canals and vegetation some had imagined. Mars gets its red colour from iron oxide dust, and the day is a chance to follow today's rovers and orbiters or look for the planet in the night sky.
