Vela 3A (original) (raw)
Vela 3A (also known Vela 5, Vela Hotel 5 and OPS 6577) was a U.S. reconnaissance satellite to detect explosions and nuclear tests on land and in space; the first of the third pair of Vela series satellites; taken together with Vela 3B and ERS 17 satellites. The secondary task of the ship was space research (X-rays, gamma rays, neutrons, magnetic field and charged particles). Sister Vela 3B was in a similar orbit, but 180 degrees from it, i.e. on the opposite side of the globe. The ship remains in orbit around Earth.

| dbo:abstract | Vela 3A (also known Vela 5, Vela Hotel 5 and OPS 6577) was a U.S. reconnaissance satellite to detect explosions and nuclear tests on land and in space; the first of the third pair of Vela series satellites; taken together with Vela 3B and ERS 17 satellites. The secondary task of the ship was space research (X-rays, gamma rays, neutrons, magnetic field and charged particles). Sister Vela 3B was in a similar orbit, but 180 degrees from it, i.e. on the opposite side of the globe. The satellite was rotationally stabilized (2 rps). The ship could work in real time mode (one data frame per second) or in data recording mode (one frame every 256 seconds). The first mode was used for the first 40% of the mission's duration. About 1 transmission was received every 4 hours. The second mode was used until the next pair of Vela satellites were launched. The ship remains in orbit around Earth. (en) Vela 3A – amerykański satelita rozpoznawczy do wykrywania wybuchów i prób jądrowych na ziemi i w przestrzeni kosmicznej; pierwszy z trzeciej pary satelitów serii Vela; wyniesiony razem z satelitami Vela 3B i ERS 17. Drugorzędnym zadaniem statku były badania przestrzeni kosmicznej (promieniowania X, gamma, neutronów, pola magnetycznego i cząstek naładowanych). Siostrzany Vela 3B znajdował się na podobnej orbicie, ale 180° od niego, tj. po przeciwnej stronie globu. Satelita był stabilizowany obrotowo (2 obr./s). Statek pracować mógł w trybie czasu rzeczywistego (jedna ramka danych na sekundę) lub w trybie zapisu danych (jedna ramka co 256 sekund). Przez pierwsze 40% czasu trwania misji używany był pierwszy tryb. Odbierano około 1 transmisji co 4 godziny. Drugiego trybu używano aż do czasu wystrzelenia następnej pary satelitów Vela. Statek pozostaje na orbicie okołoziemskiej. Po 34 latach bez śledzenia (ostatnie wyznaczenie orbity pochodziło z 1970 roku) i znajomości jego położenia został ponownie zaobserwowany przez Roberta McNaughta, a po wstępnej identyfikacji jako Vela, również przez Tony'ego Beresforda i innych.
