Snoopy was created by Charles Shultz in 1950 along with the rest of the Peanuts comic strip gang. Since Schultz was an avid space fan and supported the Apollo program of the 60's wholeheartedly, it's no wonder that Snoopy went on be chosen as NASA's mascot for quality and safety and appeared in various space-themed strips as "The Flying Ace".
The Silver Snoopy is a special honour given to employees and contractors for notable contributions to safety and mission success. The award is always given personally by NASA astronauts and consists of a small silver lapel pin flown during a NASA mission. In 1971, OMEGA received the Silver Snoopy for the Speedmaster's role in rescuing the astronauts of the Apollo 13 disaster.
The Silver Snoopy award represents "outstanding achievements related to human flight safety or mission success"
