The Cassini Flight System Spacecraft

It will function with 1,630 interlink circuits, 22,000 wire connections, and over 14 kilometers (8.7 miles) of cabling ("The Spacecraft," 1995).

The Cassini spacecraft is named for the Italian french astronomer JeanDominique Cassini (to a fault known as Gian Domenico Cassini), who discovered intravenous feeding of Saturn's major moonsIapetus, Rhea, Tethys, and Dione. In 1675, he discovered that Saturn's rings atomic number 18 split largely into two parts by a narrow gap, since known as the "Cassini Division." In earth-based analyses of the rings of Saturn, many questions were raised about the rings and about the moons. Because Saturn resembles Jupiter and spins rapidly on its axis, scientists thought it likely that Saturn has a magnetic field. To establish this, a flyby spacecraft would be needed both(prenominal) to establish its forepart and to measure its strength. The ring system of Saturn has divisions that were not thought to be empty space but regions where there were smaller amount of particles. From Earthbased observations, astronomers believed the Cassini division was about 6,000 km (3,730 miles) wide. It separates the two main bright rings, dubbed A for the outermost and B for the adjacent inner visible ring, that comprise the bright visible system. Cassini is mean to answer such issues (Fimmel, Van Allen, & Burgess, 1990).

Scientists also note that the spacecraft is steadier than any seen before, with the images it sends back unexpectedly terse and clear even in the longest exposures and in the most challenging spectral regions. Mission engineers at NASA have been running(a) with their counterparts at the European Space Agency on a business enterprise with the communication system on the Huygens canvass, which is attached to the Cassini spacecraft.

This concern was identified in early September with tests at ESA's trading operations Center at Darmstadt, Germany and involves the radio converger supplied by ESA to receive signals from the Huygens prove as it descends through Titan's atmosphere. The tests show that the signal send to Cassini from Huygens will change in frequency as both spacecraft rapidly change position in semblance to each other because of the Doppler Effect ("Cassini Mission Status," 2000). In general, though, the probe is proceeding as planned and is expected to be super successful.

The Cassini probe cost some $2.7 billion, more than the kinds of projects now being planned, but with many times their capabilities. In its seven year outbound voyage, it will skim past three planets (including genus Venus twice) before it goes into orbit around Saturn as the first spacecraft ever to do so. Earlier missions that visited Saturn - Pioneer 11 in 1979 and the twin Voyagers in 1980 and 1981 - were strictly flybys (Schefter, 1996, 60). Cassini in will sire in the vicinity of Saturn the summer of 2004 and will begin and contract an ambitious 4year scientific program to pucker an unprecedented amount of information on Saturn, including 300,000 pictures and data on its colorful atmosphere, where the equatorial wind blows at speeds faster than sound. The probe will also study the physics of Saturn's rings and its socalled she
