Sonda kosmiczna Galileo na Jowiszu

Sonda kosmiczna Galileo na Jowiszu – In October, 1989. Space shuttle Atlantis took into space probe Galileo. Did not move out of orbit straight to Jupiter, but first flew in the direction of Venus, which was used to assist gravity. In the same order twice used the Earth and finally moved toward the gas giant. Along the way, the first probe approached asteroid, specifically Gaspra, a distance of 1600 km.

Galileo probe to Jupiter was heard after 7 years and accompanied him the next 8. It became his artificial satellite. Among other things, sent into the atmosphere of Jupiter measuring instrument, which in hellish conditions lasted almost an hour. Several times flew near the Galilean moons: Io, Ganymede, Europa and Callisto. Discovered that beneath the surface of the last three is salty ocean water.

Due to the good operation of the systems, the probe mission was extended several times (the last time at the end of April 2001.). Made a total of 34 laps around Jupiter. At that time, 7 times visited Io, Callisto 8 times, as many times Ganymede, 11 times Europe.

Io najbardziej aktywny wulkanicznie

Io most active volcanically – There is, on the same conditions as in hell. It is the most active volcanic object in the solar system. Throws tons of sulfur, so its poor atmosphere composed predominantly of sulfur dioxide. On the colored surface of Io erupts approx. 400 volcanoes. And it plays an important role in shaping the magnetosphere of Jupiter.
