Jupiter to several seconds, and short bursts (or S-bursts) that had a duration of less than a hundredth of a second. Scientists discovered that there were three forms of radio signals transmitted from Jupiter. Since 1973 a number of automated spacecraft have visited Jupiter, most notably the "Pioneer 10" space probe, the first spacecraft to get close enough to Jupiter to send back revelations about the properties and phenomena of the Solar System's largest planet. Flights to other planets within the Solar System are accomplished at a cost in energy, which is described by the net change in velocity of the
Galileo Probe Galileo Probe The "Galileo" Probe was an atmospheric-entry probe carried by the main "Galileo" spacecraft to Jupiter, where it directly entered a hot spot and returned data from the planet. The probe was built by Hughes Aircraft Company at its El Segundo, California plant, measured about across. Inside the probe's heat shield, the scientific instruments were protected from extreme heat and pressure during its high-speed journey into the Jovian atmosphere, entering at per second. It entered Jupiter on December 7 1995, 22:04 UTC and stopped functioning 23:01 UTC, 57 minutes and 36 seconds later. The probe was released from the
