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. (PDT). 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 the signal to travel to Earth.
