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
Moonbase Alpha (Space: 1999) Pilot Captain Alan Carter serves as section chief. In the days before the Moon's departure from Earth, Reconnaissance was responsible for all aspects of the deep-space flight missions deployed from Alpha (see the Uranus Expedition, the Astro Seven Mission to Jupiter, the Ultra Probe and the Meta Probe among others). Medical encompasses the physician and nursing staff, plus medical orderlies and laboratory technicians—twenty-five persons in all.
