Whats Snoopy doing on Omega face?? I cant imagine Nicole Kidman wearing one 
I think the idea came from Swatch Group after they got bot over. Blame Swatch!
On the contrary, I think it's a very novel idea.
Please read this excerpt from wikipedia closely, digest and understand it.
The Silver Snoopy award is a special honor awarded to NASA employees and contractors for outstanding achievements related to human flight safety or mission success.[1][2] The award certificate states that it is "In Appreciation" "For professionalism, dedication and outstanding support that greatly enhanced space flight safety and mission success."[3] The award depicts Snoopy, a character from the Peanuts comic strip created by Charles M. Schulz.also this
Snoopy, the irreverent dog from the "Peanuts" comic strip, took time from his World War I dogfights as world-famous flying ace to become a world-famous astronaut for NASA's Apollo 10 mission.
The beagle now has a 5-foot-tall statue at Florida's Kennedy Space Center to commemorate the flight, which launched 40 years ago this month and arrived at the moon on May 21, 1969. That's when the Snoopy lunar module and the Charlie Brown command module entered lunar orbit. Apollo 10 paved the way for Apollo 11 to land men on the moon.
"It went down in his life as one of the all-time highlights of his career," said Craig Schulz, son of Charles Schulz, the famed American comic strip writer who died in 2000.

The character represents the inner child in all of us and our refusal to grow up and still keep on dreaming. That is why there was no adult representation in both visually and vocally in all Peanut comic strips and cartoon. The character is loved by all Americans and is a very part in the yarn of their popular culture.
Snoopy constantly dreams about being a WW1 fighter ace and would create and imagine dogfights with woodstock. during the height of the space euphoria in America, Snoopy was drawn looking into stars and imagining himself to be an astronaut.
Thus a friendly face was chosen to be the official mascot of NASA and what not better to name an award after an internationally known and loved figure. just like those cuddly olympic mascot.
Maybe it's time to look beyond the cute face and give a thought to what it represents.
