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
Space warfare make engaging targets in space very difficult. First, the vast distances involved mean that an error of even a fraction of a degree in the firing solution could result in a miss by thousands of kilometers. Second, space travel involves tremendous speeds by terrestrial standards—a geostationary satellite moves at a speed of 3.07 km/s whereas objects in low earth orbit can move at up to 8 km/s. Third, though distances are large, targets remain relatively small. The International Space Station, currently the largest artificial object in Earth orbit, measures slightly over 100m at its largest span. Other satellites can be
