Mariner 4 was a space probe, launched from Cape Kennedy on Saturday, November 28, 1964. It performed the first successful flyby of the planet Mars, returning the first pictures of the Martian surface to Earth (as shown below). Communications with Mariner 4 were terminated on December 21, 1967. 

On November 21, 1783, physicist Jean Francois Pilatre de Rozier, along with the
Marquis d’Arlandes, became the first humans to fly. Their flight, in a untethered hot
air balloon designed by brothers Joseph and Etienne Montgolfier, was witnessed by thousands in Paris, France including the royal family and Benjamin Franklin. It soon  
inspired a ballooning craze that exists to this day.

Apollo 12 was the second manned space flight in the Apollo program. It was
launched on November 14th and ended with a successful splashdown on the
24th of November. Key objectives were achieved including thirty one hours
of lunar surface activity.

Mariner 9 was a NASA space orbiter that was used in the exploration of the planet
Mars. It was launched toward Mars on May 30, 1971 from Cape Canaveral Air Force Station and reached the planet on November 13 of the same year, becoming the first spacecraft to orbit another planet, narrowly beating Soviet Mars 2 and Mars 3, which arrived at their destination within a month. The orbiter began sending back pictures
of the surface of Mars after months of dust storms. Below are some photos taken
as Mariner 9 approached the planet. It returned 7,329 pictures of the planet’s
surface before contact was lost on October  27, 1972.

The Gemini 12 mission was a manned spaceflight launched on November 11,
1966 as the concluding mission of NASA’s Gemini program. The objectives
were to dock with the Agena target vehicle and conduct three spacewalks. The
mission included conducting 14 scientific experiments and taking pictures of  
the total eclipse over South America. Gemini 12 returned to earth on the 15th
of November.
