Space probe comet 67P/Churyumov-Gerasimenko in November 2014. First probe to Jupiter. Radio communications were lost with Pioneer 10 on January 23, 2003, because of the loss of electric power for its radio transmitter, with the probe at a distance of 12 billion kilometers (80 AU) from Earth. First probe to fly by Saturn. (Communications were later lost due to power constraints and vast distance.) "Voyager 1" is a 733-kilogram probe launched September 5, 1977. It visited Jupiter and Saturn and was the first probe to provide detailed images of the moons of these planets. "Voyager 1" is the farthest human-made object from
Galileo Probe data for further insights into the atmosphere, and one way to do this was to study the motion of the probe during the descent down. It was found that at 700 mbar of pressure the winds on Jupiter are prograde and increase to a speed of 170 m/s at 4000 mbars of pressure. Galileo Probe has cospar ID 1989-084E while the orbiter had id 1989-084B. Names for the spacecraft include "Galileo Probe" or "Jupiter Entry Probe" abbreviated JEP.
