Galileo was made up of two parts: an orbiter and a probe. The probe was released from the orbiter on July 13, 1995 and it went towards Jupiter.[5][6] It reached Jupiter on December 7, 1995 and went down into the atmosphere.[5][6] The probe gathered data for 57 minutes until the great atmospheric heat and pressure destroyed it.[5][6]

The orbiter went into orbit around the planet on December 8, 1995[5] and went down into Jupiter's atmosphere and was crushed on September 21, 2003.[7]
