| dbo:abstract |
SOLRAD (SOLar RADiation) 3 was a solar X-ray satellite, the third in the SOLRAD program. Developed by the United States Navy's Naval Research Laboratory (USNRL), it shared satellite space with and provided cover for the Navy's GRAB 2 (Galactic Radiation And Background), a secret electronic surveillance program. The satellite was launched atop a Thor-Ablestar rocket on 29 June 1961 along with Transit 4A and the University of Iowa's Van Allen Belts Injun 1 satellite. After reaching orbit, SOLRAD 3/GRAB 2 and INJUN 1 separated from Transit 4A but not from each other. Though this reduced SOLRAD 3's data-transmission ability by half, the satellite still returned valuable information regarding the Sun's normal levels of X-ray emissions. The SOLRAD experiment package also established that, during solar flares, the higher the energy of emitted X-rays, the more disruption caused on the Earth's thermosphere (and radio transmissions therein). The GRAB mission was also highly successful, returning so much data on Soviet air defense radar facilities that an automated analysis system had to be developed to process it all. (en) Solrad 3 (ang. Solar Radiation 3 – promieniowanie słoneczne) – amerykański satelita wywiadu elektronicznego. Był trzecim statkiem z serii GRAB. Pozostawał utajniony do czerwca 1998. Zbudowany przez , NRL. Solrad 3 został wystrzelony wraz z satelitami Transit 4A i Injun 1. Injun 1 i Solrad 3 odłączyły się od Transita, ale nie odłączyły się od siebie. Chaotyczny ruch obu połączonych ze sobą satelitów, o okresie kilku minut, monitorowano jednym z magnetometrów. Statek pozostaje na orbicie, której żywotność szacuje się na 900 lat. (pl) |
