The sun passes south to north through the ring plane when Saturn's heliocentric longitude is 173.6 degrees (e.g. 11 August 2009), about the time Saturn crosses from Leo to Virgo. 15.7 years later Saturn's longitude reaches 353.6 degrees and the sun passes to the south side of the ring plane.
It consisted of two main parts, a rigid ring for structure, and within that, electronics. [31] Instrument units had a slightly different numbering scheme than the other parts. S-IU-200D/500D was for use with the SA-200D dynamic test article – a Saturn IB, and also for use with SA-500D, the Saturn V.
During its time as a test vehicle, SA-500F underwent several unique and critical evaluations to validate the facilities and procedures for the Saturn V program. SA-500F was first stacked on Mobile Launcher 1 in the Vehicle Assembly Building High Bay 1 up to the Instrument Unit on March 30, 1966.
The moons Prometheus (right) and Pandora (left) orbit just inside and outside, respectively, the F ring of Saturn, but only Prometheus is thought to function as a shepherd moon. A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects.
To test S-IC-T a special test stand was built, the B-2 Test Stand, this held the rocket in place under full power test. B-2 Test Stand was designed in 1961 and construction started in June 1961. B-2 Test Stand was completed in spring 1965 at the NASA Mississippi Test Facility and the Pearl River Site, then the NASA Mississippi Test Operations ...
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
The Saturn V instrument unit is a ring-shaped structure fitted to the top of the Saturn V rocket's third stage and the Saturn IB's second stage (also an S-IVB). It was immediately below the SLA (Spacecraft/Lunar Module Adapter) panels that contained the Apollo Lunar Module .
Cassini–Huygens (/ k ə ˈ s iː n i ˈ h ɔɪ ɡ ən z / kə-SEE-nee HOY-gənz), commonly called Cassini, was a space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites.
