          The Atmospheric Structure Instrument (ASI)
                              PDS3 CERTIFIED















Probe Science Instrument Layout


The Galileo Probe Atmospheric Structure Instrument (ASI) measured state properties of Jupiter's atmosphere from nanobar pressure levels to a final pressure of ~24 bars. The depth reached in the probe's parachute descent, calculated from measured temperatures and pressures assuming hydrostatic equilibrium, was ~160 km or 0.22% of the radius of Jupiter. Velocities during descent decreased from ~400 m/s at parachute deployment to 156 m/s in the first 100 s, to ~48 m/s at the 3-bar level, and to ~30 m/s at loss of signal.
