Kennedy Space Center Apollo 8's lunar orbiting mission. The next two missions tested the Lunar Module: Apollo 9 (Earth orbit) and Apollo 10 (lunar orbit). Apollo 11, launched from Pad A on July 16, 1969, made the first Moon landing on July 20. Apollo 12 followed four months later. From 1970–1972, the Apollo program concluded at KSC with the launches of missions 13 through 17. On May 14, 1973, the last Saturn V launch put the Skylab space station in orbit from Pad 39A. By this time, the Cape Kennedy pads 34 and 37 used for the Saturn IB were decommissioned, so Pad
Orbital station-keeping Global Geoscience WIND satellite—each have annual station-keeping propellant requirements of approximately 1 m/s or less. Earth-Sun —approximately 1.5 million kilometers from Earth in the anti-sun direction—is another important Lagrangian point, and the ESA Herschel space observatory operated there in a Lissajous orbit during 2009–2013, at which time it ran out of coolant for the space telescope. Small station-keeping orbital maneuvers were executed approximately monthly to maintain the spacecraft in the station-keeping orbit. The James Webb Space Telescope needs to use propellant to maintain its halo orbit around the Earth-Sun L2, which provides an upper limit to its designed lifetime: it
