July 16, 1969: Launch of Apollo 11

Five satellites rode a Long March 2D rocket into orbit Monday from the Jiuquan launch base in northwestern China, including a pathfinder for a planned constellation of low-altitude relay satellites and a mysterious spacecraft ambiguously described by Chinese state media.

With its payload shroud filled with multiple U.S. Air Force satellites heading for a high-altitude perch over the equator, a United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral Saturday at 7:13 p.m. EDT (2313 GMT) in its most powerful configuration with five strap-on solid-fueled boosters.

Japanese officials halted a countdown Monday at the Tanegashima Space Center when teams overseeing preparations for launch of an H-2A rocket detected a nitrogen gas leak, prompting the return of the launcher and its Japanese government payload to a nearby assembly building for repairs.
