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
Saturn Atmospheric Entry Probe Saturn Atmospheric Entry Probe The Saturn Atmospheric Entry Probe is a mission concept under study since 2010, where a robotic spacecraft would deliver a single probe into Saturn to study its atmosphere. Due to the orbits and relative positions of Saturn and Earth, launch is proposed for August 30, 2027 for a June 22, 2034 arrival. The mission is under review in order to compete for funding by NASA's New Frontiers Program. To unveil the processes of outer planet formation and Solar System evolution, detailed studies of the composition, structure, and dynamics of giant planet interiors and atmospheres would be
