Galileo (Spacecraft and Satellite Navigation)

After the Challenger accident, a study considered additional shielding and eventually rejected it, HP Pavilion dv7-6097ef Battery in part because such a design significantly increased the overall risk of mission failure and only shifted the other risks around (for example, if a failure on orbit had occurred, additional shielding would have significantly increased the consequences of a ground impact).[7]

[edit]Instrumentation overviewHP G62-100 Battery

Scientific instruments to measure fields and particles were mounted on the spinning section of the spacecraft, together with the main antenna, power supply, the propulsion module and most of Galileo’s computers and control electronics. The sixteen instruments, weighing 118 kg altogether, HP G62-100EB Battery included magnetometer sensors mounted on an 11 m boom to minimize interference from the spacecraft; a plasma instrument for detecting low energy charged particles and a plasma wave detector to study waves generated by the particles; a high energy particle detector; and a detector of cosmic and Jovian dust. HP G62-100EE Battery It also carried the Heavy Ion Counter, an engineering experiment added to assess the potentially hazardous charged particle environments the spacecraft flew through, and an added Extreme Ultraviolet detector associated with the UV spectrometer on the scan platform.

The despun section’s instruments included the camera system; HP G62-100EJ Battery the near infrared mapping spectrometer to make multi-spectral images for atmospheric and moon surface chemical analysis; the ultraviolet spectrometer to study gases; and the photo-polarimeter radiometer to measure radiant and reflected energy. HP G62-100SL BatteryThe camera system was designed to obtain images of Jupiter’s satellites at resolutions from 20 to 1,000 times better than Voyager’s best, because Galileo flew closer to the planet and its inner moons, and because the more modern CCD sensor in Galileo’s camera was more sensitive and had a broader color detection band than the vidicons of Voyager. HP G62-101TU Battery
