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
Neil Armstrong the surface of the Moon occurred several seconds after 20:17:40 UTC on July 20, 1969. One of three probes attached to three of the lunar module's four legs made contact with the surface, a panel light in the LM illuminated, and Aldrin called out, "Contact light." Armstrong shut the engine off and said, "Shutdown." As the LM settled onto the surface, Aldrin said, "Okay, engine stop"; then they both called out some post-landing checklist items. After a ten-second pause, Duke acknowledged the landing with, "We copy you down, "Eagle"." Armstrong announced the landing to Mission Control and the world with
