Commemorating the day one of the most significant space missions to Mars was launched, November 28 is marked as Red Planet Day.
Details
On this day in 1964, the United States launched the space craft Mariner 4 on a course towards Mars, which it flew past in July 1965, sending back pictures of the red planet.
This was the first time that a spacecraft undertook the first flyby of the red planet, becoming the first-ever spacecraft to take close-up photographs of another planet.
