The history of NASA and Charles Schulz's Peanuts dates back to 1968 when Snoopy was named the aerospace agency's safety mascot — a distinction held to this day through the Silver Snoopy Award program. The connection led to another partnership a year later, when the crew of Apollo 10 chose to nickname their command and lunar modules Charlie Brown and Snoopy. The dress rehearsal for the lunar landing was a success and is celebrated 50 years later with this limited edition t-shirt. Available in black, grey, and white, the shirt features a space-ready Snoopy walking above the year 1969.
