Apollo X - Snoopy becomes an Astronaut

Apollo 10 was the fourth manned mission in the Apollo program. Launched on May 18, 1969, it was the "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing. The Lunar Module came to within 9.6 miles of the moon’s surface, the point where the powered descent to the lunar surface would begin. The success of Apollo 10 allowed the first landing to be attempted on Apollo 11 in July, 1969.According to the 2002 Guinness World Records, Apollo 10 set the record for the highest speed attained by a manned vehicle at 24,791 mph during the return from the Moon on May 26, 1969. Due to the use of their names as call signs, the Peanuts characters Charlie Brown and Snoopy became semi-official mascots for the mission. Peanuts creator Charles Schulz also drew some special mission-related artwork for NASA.

For NASA, he flew aboard two Gemini space flights; and in 1969 was the Commander of Apollo 10. In 1975, Stafford was Commander of the Apollo-Soyuz Test Project flight, the first joint U.S.-Soviet space mission. A Brigadier General at the time, he became the first general officer to fly in space. He was the first member of his Naval Academy class to pin on the first, second and third stars of a general officer. He made six rendezvous in space and logged 507 hours of space flight. He has flown over 120 different types of fixed wing and rotary aircraft and three different types of spacecraft.

John Watts Young (born September 24, 1930), is a retired, US Navy Captain and aviator, test pilot, and aeronautical engineer. In 1965, Young flew on the first manned Gemini mission. In 1969 was the first person to orbit the Moon alone during Apollo 10. He became the ninth person to walk on the Moon as Commander of the Apollo 16 mission in 1972. Young had the longest career of any astronaut, becoming the first person to make six space flights over the course of 42 years of active NASA service and is the only person to have piloted, and been commander of, four different classes of spacecraft: Gemini, the Apollo Command/Service Module, the Apollo Lunar Module, and the Space Shuttle. He is one of only three people to have twice journeyed to the Moon. Young set a speed record driving the Lunar Rover on the Moon's surface. He also commanded two Space Shuttle flights, including its first launch in 1981, and served as Chief of the Astronaut Office from 1974–1987. Young retired from NASA in 2004.
