The outer solar system exploration was kick started by Pioneer 10 and 11 in 1973 and 74 followed by Voyager 1 and 2 in 1979.The European Probe Ulysses on route to the Sun in 1992 and the space probe Galileo in 1996 orbited the planet, then the Cassini Hughyens probe for millennium on route to Saturn. New horizons in 2007 pushed further exploration on her way to Pluto.
Like a dare devil uncaring for its own life, Pioneer 11 hit the Bow Shock of Saturn on August the thirty first, 1979 and took the risk so that Voyager 1 in November 1980 and Voyager 2 in August 1981 could safely accomplish their mission. Cassini in2004 orbited Saturn until 2017 making a complete study of the planet, its ring system and its multiple moons.
The only planetary space probe to have visited the tilted ice giant Uranus was Voyager 2 in January 1986 when she flew by and explored Uranus’s extreme eccentric magnetic field,, its young planetary rings and its chaotic moon Miranda which is a complete geological enigma with its fractures, cracks and giant rifts.
The venerable Voyager 2 reached Neptune on the twenty sixth of August 1989 and has so far provided the bulk of the data on the Neptunian system. Neptune was found to have the most violent wind system in the solar system with speeds of approximately one thousand two hundred kilometres per hour. Its moon showed Triton had a young surface with intense geological activity and cryo-volcanic geyser. Voyager two showed Triton was once a standalone planet orbiting the Sun and is the only planetary sized moon around Neptune.
The arrival of New Horizons at Pluto on the fourteenth of July 2015 as it flew by brought into focus the recently demoted Pluto’s Planetary attributes which it stubbornly resisted, as it was found to be astonishingly geologically active with cryo volcanoes which h
Astroverbot Julia Valle Marineris
In our solar System, features like the towering volcano Olympus Mons and one of the largest systems of canyons, Valle Marineris on Mars, stand out for the sheer vastness and majesty of their size. Named after the famous Mariner 9 Mars Orbiter, the Valles Marineris runs for 4 thousand kilometres along the Equator of Mars with a width of 200 kilometres and up to 7 kilometres in depth. In all, it covers around a quarter of Mars’s circumference and various theories as to its occurrence included water or carbon dioxide eroding the surface and the erosion of the lava flows from Pavonis Mons. The accepted reason at present is tectonic cracking of the crust of Mars due to the thickening of the crust in the Tharsis region, like the rift faults created on earth. Starting from Noctis Labrynthis canyon in the West and running to the East from Tithonium up until the Eos canyon, these chasmata or chasms end in the region of the outflow channel leading to the basin of Chryse Planitia. Their terrains are a result of the violent discharge of ground fluid in cataclysmic circumstances where the liquid could be carbon dioxide ice and gas, water or lava much like the Scablands of Eastern Washington on Earth but on a vaster scale.
Mars has 2 moons, Phobos which is the innermost and largest with a mean radius of 11 kilometres and Deimos named after the God of War’s sons. Orbiting only 6 thousand kilometres from the surface of Mars, Phobos appears to rise in the West, set in the East and because it orbits Mars faster than Mars rotates, it orbits Mars twice in a day. It has a large impact crater Stickney, and is thought to be composed of a large pile of rubble held in place by a thin crust. However due to the tidal forces it is subject to being so close to Mars, it is slowly being torn apart and will eventually crash into Mars itself or become a planetary ring in about 30 to 50 million years. It’s very lack of density and the porosity of its regoli
