AMSAT (Radio Amateur Satellite Corporation - was first formed in the District of Columbia in 1969 as an educational organization. Its goal was to foster Amateur Radio's participation in space research and communication. AMSAT was founded to continue the efforts, begun in 1961, by Project OSCAR, a west coast USA-based group which built and launched the very first Amateur Radio satellite, OSCAR, on December 12, 1961, barely four years after the launch of Russia's first Sputnik.
Manned (piloted) astronautics. Figures and facts. – Very interesting and learnfull site about space, space vehicles, satellites.
Rocket and Space Public Corporation Energia after S.P. Korolev Is the strategic enterprise of Russia and the leading company engaged in manned space systems. A great deal of attention is focused on the development of new space technologies, including dedicated unmanned space systems for various applications, rocket systems for spacecraft orbital injection. Its presence is noticeable on the international market of rocket and space services. It is the leader in introducing space high technologies for manufacture of products not related to space industry.
ARISS (Amateur Radio on the International Space Station) - Is a volunteer program which inspires students, worldwide, to pursue careers in science, technology, engineering and math through amateur radio communications opportunities with the International Space Station (ISS) on-orbit crew. Students learn about life on board the ISS and explore Earth from space through science and math activities. ARISS provides opportunities for the school community (students, teachers, families and local residents) to become more aware of the substantial benefits of human spaceflight and the exploration and discovery that occur on spaceflight journeys along with learning about technology and amateur radio.
SatObs - Visual Satellite Observer's - If you have ever star-gazed shortly after sunset or before sunrise, you have probably noticed one or two "stars" sailing gracefully across the sky. These are Earth-orbiting satellites, visible due to the reflection of the Sun's light off their surfaces toward the observer. Hundreds of satellites are visible to the unaided eye; thousands are visible using binoculars and telescopes. Observing satellites has many enthusiasts around the world.
Celestrak - Information about sattelites - One of the older site about satellite. Many programms and information about satallites autor T.S. Kelso.
Heavens-Above - оbserving and tracking satellites - is a web site dedicated to observing and tracking satellites orbiting the Earth. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen when looking up. Special attention is paid to the ISS, Iridium flares, recent space shuttle missions, and other satellites currently visible from Earth. The website also offers information on currently visible comets, asteroids, planet details, and other miscellaneous information. Sky and Telescope magazine calls "the most popular website for tracking satellites."
