Lunar orbit rendezvous (LOR) is a process for landing humans on the Moon and returning them to Earth. It was utilized for the Apollo program missions in the 1960s and 1970s. In a LOR mission, a main spacecraft and a smaller lunar lander travel to lunar orbit. The lunar lander then independently descends to the surface of the Moon, while the main spacecraft remains in lunar orbit. After completion of the mission there, the lander returns to lunar orbit to rendezvous and re-dock with the main spacecraft, then is discarded after transfer of crew and payload. Only the main spacecraft returns to Earth.
Lunar orbit rendezvous was first proposed in 1919 by Ukrainian engineer Yuri Kondratyuk, as the most economical way of sending a human on a round-trip journey to the Moon.

…that a CubeSat (pictured) is a cube, 10 centimetres in all dimensions, weighing less than one kilogram?
…that the Vostok 4 mission was shortened because cosmonautPavel Romanovich Popovich accidentally told flight controllers that he was "observing thunderstorms". This was a coded signal requesting an abort because the cosmonaut was feeling ill, however Popovich was actually trying to inform ground controllers that he could see thunderstorms from space.
…that the backup crew of Apollo 11 consisted of Jim Lovell, Bill Anders and Fred Haise, although after Anders announced his intention to retire, Ken Mattingly was also assigned in case the mission was delayed until after Anders had left? The backup crew, with Mattingly replacing Anders, was later assigned to Apollo 13.
