Snoopy is home: NASA photos show 'zero-g indicator' after moon trip

January 11, 2023

— Snoopy has come home.

The "world famous astronaut" splashed down aboard NASA's Artemis I Orion spacecraft in December, but it was not until last week that Snoopy — or rather a plush version of the comic strip beagle — was ready to be removed from the flown-to-the-moon capsule. NASA photos taken on Jan. 5, show the doll being carefully handled before being packed back into its carry case.

The images are the first time that the doll has been seen in close-up since it was launched on the Artemis I mission on NASA's first Space Launch System (SLS) rocket on Nov. 16, 2022. During the 25.5-day flight, which logged more than 1.4 million miles (2.3 million km) looping around the moon, Snoopy was only seen at a distance, floating at the end of his leash (otherwise known as a tether) at the bottom of Orion's crew cabin as viewed from a camera mounted on the aft wall.

The custom-made doll served as the mission's "zero-g indicator," a tradition that was borrowed from the Russian space program that uses toys to signal when the spacecraft has entered the microgravity environment of space.

The new photos show Snoopy is no worse the wear for the trip. Sporting a wide smile, the plush flew to the moon and back in a miniature version of NASA's Orion Crew Survival System (OCCS) pressure suit, made out of some of the same materials used to produce the real garments. A full-size suit was also tested on Artemis I, as worn by "Commander Moonikin Campos," an instrumented manikin named after an Apollo 13 engineer.

After landing off the coast of Mexico's Baja California Peninsula on Dec. 11, Snoopy and Commander Campos stayed inside the Orion as it was transported by truck from Naval Base San Diego in California to the Kennedy Space Center in Florida. The spacecraft was delivered to NASA's Multi-Payload Processing Facility on Dec. 30.

Engineers have now removed some of Orion's exterior back shell panels and have opened the hatch as the capsule undergoes post-flight study and analysis.

The Artemis I mission was primarily flown as a test of the spacecraft's heat shield, proving it could safely return from the moon and reenter Earth's atmosphere. The flight also verified that Orion's systems were ready to support flying astronauts as planned for the Artemis II mission targeted for launch in late 2024 or 2025.

Though this was Snoopy's first flight to the moon as a zero-g indicator, his history with NASA dates back the Apollo program when illustrator Charles Schulz agreed to the character symbolizing NASA's safety culture and mission success. The Apollo 10 lunar module was named "Snoopy" (the command module was "Charlie Brown") and the "Silver Snoopy" is one of the highest honors NASA astronauts award to employees and contractors for their support bringing them home safely.

In 2018, NASA and Peanuts Worldwide expanded use of Snoopy and the entire Peanuts gang as new mascots for science, technology, engineering and mathematics (STEM) education and the space agency's deep space missions.
