: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>

==NASA Unmanned Missions==
*Explorer 1 was the first satellite launched by the United States when it was sent into space on January 31, 1958. Following the launch of the Soviet Union's Sputnik 1 on October 4, 1957, the U.S. Army Ballistic Missile Agency was directed to launch a satellite using its Jupiter C rocket developed under the direction of Dr. Wernher von Braun. The Jet Propulsion Laboratory received the assignment to design, build and operate the artificial satellite that would serve as the rocket's payload. JPL completed this job in less than three months.
:The primary science instrument on Explorer 1 was a cosmic ray detector designed to measure the radiation environment in Earth orbit. Once in space this experiment, provided by Dr. James Van Allen of the University of Iowa, revealed a much lower cosmic ray count than expected. The existence of these radiation belts was confirmed by another U.S. satellite launched two months later, and they became known as the Van Allen Belts in honor of their discoverer. <ref> http://www.nasa.gov/mission_pages/explorer/explorer-overview.html </ref>
