The Saturn V was a human-rated expendable rocket used by NASA between 1967 and 1973. Most notably, the Saturn V took the Apollo program to the Moon. It still remains the world's tallest, heaviest, and most powerful rocket ever brought to operational status and is the only launch vehicle to take humans beyond LEO.
Apollo 10 was Command by Thomas P. Stafford, Command Module Pilot John W. Young, and Lunar Module Pilot Eugene A. Cernan. This mission was a F Mission which means a dress rehearsal for the upcoming Apollo 11 Mission that would be the first crewed mission to land on the moon.
