Galileo End of Mission Status The Galileo spacecraft's 14-year odyssey came to an end on Sunday, Sept. 21, when the spacecraft passed into Jupiter's shadow then disintegrated in the planet's dense atmosphere at 11:57 a.m. Pacific Daylight Time. The Deep Space Network tracking station in Goldstone, Calif., received the last signal at 12:43:14 PDT. The delay is due to the time it takes for the signal to travel to Earth.

From the Sun to the Earth: Polar, Wind and Geotail Polar, Wind, and Geotail are fundamental elements in NASA's global approach to understanding the Sun-Earth Connections system. Operating as a distributed laboratory in space, events are routinely followed from their birth on the Sun, traced through the interplanetary medium, and then studied in terms of their effectiveness in creating geomagnetic storms and substorms in our near Earth environment. The focus is on understanding the dynamics ...

Neptune, which is usually the eighth planet from the Sun, is a very cold place. Occasionally, the ninth planet Pluto crosses Neptune's orbit and becomes the "eigth planet". Its bluish color comes from its atmosphere of methane gas. The planet has moons and a very narrow, faint ring system.
