Apollo 10’s main purpose was to test rendezvous and docking operations between the Command and Service Module (CSM) and the Lunar Module (LM) in lunar orbit. Having entered orbit around the Moon, astronautsStafford and Cernan transferred to the LM, undocked it, and flew within 15,200 meters of the Moon's surface. After the LM descent stage had been jettisoned prior to re-docking, the orientation of the ascent stage began to change unexpectedly due, it turned out, to an incorrectly placed switch. The astronauts took manual control of the LM and were able successfully to rendezvous and re-dock with the CSM. The Apollo 10 crew achieved the highest speed ever attained by human beings – 39,896 km/h. This was also the highest speed of entry into Earth's atmosphere by any spacecraft until it was surpassed by the Stardust probe.
