As it arrived at Jupiter on December 7, 1995, 
NASA's Galileo orbiter received a stream of data 
transmissions -- represented by the blue dots in 
this artist's depiction -- from the atmospheric 
probe that was descending through Jupiter's clouds. 
The orbiter had released the probe five months 
earlier. The wok-shaped probe sent information to 
the orbiter for 57.6 minutes as it dropped about 
200 kilometers (125 miles) through the atmosphere, 
before succumbing to atmospheric pressure about 23 
times greater than the average at Earth's sea 
level. The probe returned data about sunlight, 
heat flux, pressure, temperature, winds, lightning 
and atmospheric composition. About one hour after 
the end of the probe's transmissions, the orbiter 
fired its main engine to brake into orbit around 
Jupiter. The Jet Propulsion Laboratory, a division 
of the California Institute of Technology in 
Pasadena, manages the Galileo mission for NASA's 
Office of Space Science, Washington, D.C.
