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
The Jupiter Theft into an alien contact scenario. The "intruder" is actually the silicate core of a Jovian planet, orbited by a moon and five immense alien spacecraft. The Jupiter Mission is intercepted in mid-space by aliens, dubbed Cygnans, riding on matter-annihilation powered "broomsticks". The mission is essentially destroyed, with the surviving crew taken alive as specimens for a Cygnan zoo. Now imprisoned, the Sino-American crew attempt contact with the Cygnans and seek to discover their true purpose in appearing in the Solar System. Using a Moog synthesizer and their natural gift of perfect pitch, one of the crew learns first to understand
