Uranus : the planet seventh in order from the sun — Webster   See also   OneLook


Uranus is the seventh planet from the Sun. Its name is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares (Mars), grandfather of Zeus (Jupiter) and father of Cronus (Saturn). It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as “ice giants” to distinguish them from the other giant planets. — Wikipedia

If you are over a billion miles from the Earth and Sun, the need to create your own energy to power your living needs can be difficult. But if you have a giant gas planet with lots of Helium 3 nearby, all you need to do is find a way to scoop up some for your needs. As a sequence for a planetarium program showing possible future NASA exploration directions, Home Run Pictures, working with NASA scientists, visualized engineering concepts for a space station that would dive into the upper atmosphere of the planet Uranus. Since this was an educational program, avoiding being too science fiction-like was difficult at times, but the concept involved a space station in an elliptical orbit that would once every several orbits, dive into the upper atmosphere of the planet. The Uranus Helium 3 Ram Scoop space station sequence is part of NASA funded The Great Planet Adventures Planetarium Show fulldome planetarium show.

Voyager Program is an American scientific program that employs two robotic interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable alignment of Jupiter and Saturn, to fly near them while collecting data for transmission back to Earth. After launch the decision was taken to send Voyager 2 near Uranus and Neptune. — Wikipedia

William Herschel observed Uranus on 13 March 1781 from the garden of his house at 19 New King Street in Bath, Somerset, England (now the Herschel Museum of Astronomy), and initially reported it (on 26 April 1781) as a comet. With a homemade 6.2-inch reflecting telescope, Herschel engaged in a series of observations on the parallax of the fixed stars. — Wikipedia
