Galileo Atmospheric Probe

Galileo Probe and its Descent Profile

Classification: Atmospheric probe spacecraft

Mission: Investigate Jupiter's atmosphere

Features: The Galileo Atmospheric Probe was released from the Galileo orbiter spacecraft in July 1995, about 100 days before arrival at Jupiter. Atmospheric entry took place on 7 December 1995 as the orbiter tracked the probe and recorded its data for later relay to Earth. Probe instruments investigated the chemical composition and the physical state of the atmosphere. The probe returned data for just under an hour before it was overcome by the pressure of Jupiter's atmosphere.

Stabilization: Spin stabilized on trajectory from release until entry.
