Apollo 10 was the fourth manned mission of Project Apollo, and the second lunar mission of the Apollo program. The mission functioned as a dress rehearsal for the moon landing by the following mission, Apollo 11. A lunar module descended to within 10 miles of the moon's surface, but did not land. Rendezvous and docking with the command module were successfully accomplished.

NASA film JSC-519

Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Apollo 10 was the fourth manned mission in the United States Apollo space program, and the second (after Apollo 8) to orbit the Moon. Launched on May 18, 1969, it was the F mission: a "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing. The Lunar Module (LM) followed a descent orbit to within 8.4 nautical miles (15.6 km) of the lunar surface, at the point where powered descent for landing would normally begin. Its success enabled the first landing to be attempted on the Apollo 11 mission two months later.

According to the 2002 Guinness World Records, Apollo 10 set the record for the highest speed attained by a manned vehicle: 39,897 km/h (11.08 km/s or 24,791 mph) on May 26, 1969, during the return from the Moon.

The mission's call signs included the names of the Peanuts characters Charlie Brown and Snoopy, which became Apollo 10's semi-official mascots. Peanuts creator Charles Schulz also drew some mission-related artwork for NASA... 

Upon descent stage separation and ascent engine ignition, the Lunar Module began to roll violently because the crew accidentally duplicated commands into the flight computer which took the LM out of abort mode, the correct configuration for this maneuver. The live network broadcasts caught Cernan and Stafford uttering several expletives before regaining control of the LM. Cernan has said he observed the horizon spinning eight times over, indicating eight rolls of the spacecraft under ascent engine power. While the incident was downplayed by NASA, the roll was just several revolutions from being unrecoverable, which would have resulted in the LM crashing into the lunar surface...
