On this day 55 years ago, #NASA launched the Apollo 11 lunar mission and three astronauts began their journey to the Moon. One major task during the mission involved installing a lunar laser-ranging retroreflector designed to measure the distance between the Earth and the Moon within a millimetre. The first lunar ranging tests were completed in 1962 and were designed to better understand the Moon's gravitational forces. By installing a reflector on the Moon's surface, scientists could begin measuring these forces with higher precision. This work was vital to developing GPS and other GNSS satellites as scientists could better understand impacts on a satellite's orbit and synchronicity to control stations. The Apollo 11 retroreflector was the first to be installed in space; now, every satellite is equipped with this proven technology to uphold the highly precise position, navigation and timing measurements people rely upon every day.
