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
NASA Uranus orbiter and probe NASA Uranus orbiter and probe A Uranus orbiter and probe is a mission concept for study of the planet Uranus. It was first recommended to NASA in 2011 by its Planetary Science Decadal Survey 2013–2022. NASA evaluated in 2017 twenty different mission designs submitted by the scientific community, considering mission trades, trajectories, and the technology required for specific objectives. Because of planet position and alignments, Neptune was dropped in favor of Uranus. If funded, the proposed mission would launch in the 2020s with launch-windows of 21 days every year. The survey listed the Uranus orbiter and probe as the third
