[Apollo 10]

The present photograph depicts the Apollo 10 mission, whose call signs were the names of the Peanuts characters. Here, the Lunar Module "Snoopy" approaches the Command/Service Module "Charlie Brown" for redocking.

The crew of Apollo 10 named their spacecraft after the beloved Peanuts characters to raise awareness of the Manned Flight Awareness (MFA) Program. Peanuts creator Charles Schulz gave his full blessing to NASA for Snoopy to be adopted as the mascot for the MFA and to be used as a "spokesperson" to emphasize flight safety, quality control, and other related topics during spacecraft manufacturing.

The Apollo 10 mission laid the key groundwork for the historic moon landing of Apollo 11, and launched Snoopy as a beloved NASA mascot. Lunar Module Pilot Gene Cernan later returned to the Moon as Commander of Apollo 17. In 1972, Cernan was last man to walk on the lunar surface as he stepped into the LM Challenger.
