*'''Project Apollo ''' On May 25, 1961, President [[John F. Kennedy]] announced the goal of sending a man to the moon before the end of the decade. Coming just three weeks after Mercury astronaut Alan Shepard became the first American in space, Kennedy's bold challenge set the nation on a journey unlike any before in human history.

:Eight years of hard work by thousands of Americans came to fruition on July 20, 1969, when the lunar module landed in the [[Sea of Tranquility]] and [[Apollo 11]] commander [[Neil Armstrong]] stepped onto the moon's surface with the words, "That's one small step for man, one giant leap for mankind."

:Six of the missions -- Apollos 11, 12, 14, 15, 16 and 17 -- went on to land on the moon, studying soil mechanics, meteoroids, seismic, heat flow, lunar ranging, magnetic fields and solar wind. Apollos 7 and 9 tested spacecraft in Earth orbit; Apollo 10 orbited the moon as the dress rehearsal for the first landing. An oxygen tank explosion forced [[Apollo 13]] to scrub its landing, but the "can-do" problem solving of the crew and mission control turned the mission into a "successful failure."

:The station now includes the Russian-built Zarya Module and the Zvezda Service Module, which contain the station’s living quarters and life-support systems; the U.S.-built Unity Connecting Module, providing docking ports for several station components; the U.S.-built Destiny Laboratory, which expands the station’s scientific capabilities with experiment compartments that allow nearly continuous scientific research and provide additional life support and robotic capabilities; the U.S.-built Quest Airlock, a doorway to space that supports station-based spacewalks; the Canadian-built Canadarm2, a new-generation robotic arm that gives the station a movable space crane; the Russian-built Pirs docking compartment, which adds additional spacewalking and docking capabilities to the station; and truss segments, which serve as the framework for additional station segments. Japanese and European research laboratories are ready for delivery to expand the station’s research capabilities even more. <ref> http://spaceflight.nasa.gov/spacenews/factsheets/index.html </ref>
