Lowry Digital completed the full moonwalk restoration project in late 2009. Apollo 11 was the spaceflight that landed the first two people on the Moon. Neil Armstrong became the first person to step onto the lunar surface on July 21, 1969, at 02:56 UTC; Buzz Aldrin joined him about 20 minutes later. Only limited radio bandwidth was available to transmit the video signal from the lunar landings, which needed to be multiplexed with other communication and telemetry channels beamed from the Lunar Module, back to Earth.
