Produced by Takara (Japanese).History:THE VOYAGER SPACECRAFTThe Voyager spacecraft is a marvel in any context. It is a showcase for mid 1970s technology. It can point its scientific sensors to an accuracy of 0.1 of a degree. As it shoots past a planet or moon, tiny Hydrazine rocket motors with a thrust of only 85 grams can hold the spacecraft 60 times steadier than the hour hand of an analog clock. The telephoto television cameras are powerful enough to resolve a newspaper headline from 1 km away. There were 60 scientists and engineers at JPL, known as the Spacecraft Team, looking after the spacecraft, at any given moment half would be busy with planning the mission, while the other half were engaged in analysing the data being sent from the spacecraft.Each spacecraft has 65,000 individual parts, one computer memory alone contains over a million electronic parts, but by today’s standards its total memory capacity was only a mere 514 kilobits, which would hardly rate a calculator these days. Expecting radiation doses over one thousand times the lethal level for humans, these sensitive components were radiation hardened and shielded from the harsh space environment. In the navigation department, the toughest target was Neptune, where the target accuracy at the planet of 100 kilometres, divided by the trip distance (arc travelled to the planet from Earth) of 7,128,603,456 kilometres is equivalent to sinking a 3,630 kilometre long golf putt!Their fuel efficiency on arrival at Neptune was 13,000 kilometres per litre. This efficiency will continue to improve until the fuel runs out.The rings around Uranus were so dark, it was comparable to photographing charcoal at a distance of 3 metres illuminated only a one watt bulb using 64 ASA film.Sending data back to Earth was a technical marvel. Images begin to smear if the spacecraft is travelling more than 100,000 kph (62,139 statute miles per hour), so the spacecraft has to turn to keep the subject firmly locked in the camera lens. Then the data rates drop dramatically as the spacecraft moves further out. At Jupiter, for instance, the telemetry data rates were a high 115.2 kilobits per second. By Saturn they were down to 44.8 kps, so it took a lot longer to transmit the same amount of data.Voyager 1 made its closest approach to Jupiter on 5 March 1979 at a distance of 206,700 kilometres above the cloud tops, followed by Voyager 2 on 9 July 1979 at 570,000 kilometres.The Voyager 1 and 2 Saturn flybys occurred 9 months apart, Voyager 1 on 12 November 1980 at a distance of 64,200 kilometres, and Voyager 2 on 25 August 1981 at a distance of 41,000 kilometres. Saturn is the second largest planet of the solar system, taking 29.5 Earth years to circle the Sun once, its spin making a Saturn day 10 hours 39 minutes long. It has 17 moons, with a very complex ring system.Shipping and HandlingWe combine shipment and reduce shipping cost if you have multiple purchases.
