Radio Solar Telescope Network Radio Solar Telescope Network The Radio Solar Telescope Network (RSTN) is a network of solar observatories maintained and operated by the 557th Weather Wing, ACC. The RSTN consists of ground-based observatories in Australia, Italy, Massachusetts, New Mexico and Hawaii. It became apparent in the early 1960s that certain space weather events might interfere with the stated U.S. objective of a manned mission to the moon. In particular, the sun emits continuous electromagnetic energy and electrically charged particles, which can cause disturbances in the near-Earth environment and disrupt satellite communications. Foremost among these concerns was the possibility of a geomagnetic storm
Discovery and exploration of the Solar System Earth was Yuri Gagarin, a Soviet cosmonaut who was launched in "Vostok 1" on April 12, 1961. The first human to walk on the surface of another Solar System body was Neil Armstrong, who stepped onto the Moon on July 21, 1969 during the "Apollo 11" mission; five more Moon landings occurred through 1972. The United States' reusable Space Shuttle flew 135 missions between 1981 and 2011. Two of the five shuttles were destroyed in accidents. The first orbital space station to host more than one crew was NASA's Skylab, which successfully held three crews from 1973 to 1974. True
