![]() ![]() More than 100 scientists from United States, Great Britain, Germany, France, Canada and Sweden carried out Galileo's experiments. International contribution estimated at an additional $110 million Total from start of planning through end of mission was $1.39 billion. Solid-state imaging camera, near-infrared mapping spectrometer, ultraviolet spectrometer, photopolarimeter radiometer, magnetometer, energetic particles detector, plasma investigation, plasma wave subsystem, dust detector, heavy ion counterĥ0 inches (127 centimeters) in diameter, 36 inches (91 centimeters) high, weighed 750 pounds (339 kilograms)Īpproximate number of people who worked on some portion of the Galileo mission: Power : 570 watts (at launch) from radioisotope thermoelectric generators.Weight : 4,902 pounds (2,223 kilograms), including 260 pounds (118 kilograms) of science instruments and 2,040 pounds (925 kilograms) of propellant.Size: 17 feet (5.3 meters) high magnetometer boom extended 36 feet (11 meters) to one side.Total distance traveled, launch to impact:Ībout 2.8 billion miles (4.6 billion kilometers) Speed of atmospheric entry at mission end:ġ06,000 miles per hour (47 kilometers per second) - equivalent of traveling from Los Angeles to New York City in 82 seconds Spacecraft entered Jupiter’s atmosphere on Sept. ![]() Io 7, Callisto 8, Ganymede 8, Europa 11, Amalthea 1 Number of Jupiter orbits during entire mission: Impacts of comet fragments into Jupiter observed while en route in July 1994 18, 1989 from Kennedy Space Center, Fla., aboard space shuttle Atlantis This enables the instruments to image the polar regions of the Sun clearly for the first time and make key measurements that will advance our understanding of the solar dynamo and the polarity reversal of the global magnetic field. It was the first spacecraft to operate in a giant planet magnetosphere long enough to identify its global structure and to investigate its dynamics. During the nominal mission, Solar Orbiter views the Sun from latitudes of up to 24.It made the first, and so far only, direct observation of a comet colliding with a planet’s atmosphere (Shoemaker-Levy 9).It completed the first flyby and imaging of an asteroid (Gaspra, and later, Ida).It was the first spacecraft to deploy an entry probe into an outer planet's atmosphere.Galileo was the first spacecraft to orbit an outer planet. ![]()
