Flight

Launch from Cape Canaveral (KSC); landing east of Samoa Islands in the Pacific Ocean.

Apollo 10 was the final dress rehearsal for the moon landing and the second manned lunar orbital mission, but first lunar orbital mission with the complete spacecraft (including the lunar module).

Shortly after leaving the low Earth orbit, the command/service module separated from the S-IVB stage, turned around, and docked its nose to the top of the lunar module still nestled in the S-IVB. The CSM/LM stack then separated from the S-IVB for the trip to the Moon.

On May 22, 1969 the spacecraft were separated. Spacecraft and the LM, named Snoopy, with Thomas Stafford and Eugene Cernan onboard was inserted into a descent orbit, John Young remained alone in his command module "Charlie Brown". The LM was taken within 15,243 km of the lunar surface, checking out the LMs radar and ascent engine and several more. The lunar module returned to dock successfully with the CSM following the eight hour separation, and the LM crew returned to the CSM. The LM ascent stage was jettisoned. During leaving the moon orbit the LM began to reel because of technical problems (incorrect switch setting was the reason). 31 lunar orbits were performed. Apollo 10 also added another first - broadcasting live color TV from space (19 different broadcasts were performed).

The splashdown was 5,4 kilometers from the recovery ship USS Princeton.
