Toutatis.jpgEarth from the asteroid "Toutatis"102 visiteOn September 29, 2004, the Earth came within 1 million miles of the asteroid Toutatis - the closest predicted approach of our fair planet to a sizable asteroid or comet in this century. Coming within 1 million miles (or about 4 times the Earth-Moon distance), Earth would appear to be nearly the size of the full moon in the asteroid's sky, as suggested in this illustration. In Earth's sky, Toutatis appeared only as a faint object rapidly moving against a background of stars. Also known as Earth-Crossing Asteroid (ECA) 4179, Toutatis is in an eccentric 4 year orbit which moves it from the asteroid belt between Mars and Jupiter to just inside Earth's orbit. When the Earth passed near it in 1992 Toutatis was imaged by radar and seen to be 2 irregularly shaped lumps, perhaps joined by a narrow neck. This bizarre object is about 3 Km wide, 5,5 Km long and is tumbling through space. Studies of Toutatis and other ECA's help reveal connections between the Solar System's meteorites main-belt asteroids and comets.Ott 01, 2004

Landing on Mars.jpgLanding on Mars151 visiteA livello di curiosità Vi suggeriamo, se volete vedere una ricostruzione davvero molto credibile di un futuro "landing on Mars" (a base di paracadute prima ed airbags poi), la sequenza della discesa della capsula di emergenza con 5 astronauti a bordo che viene presentata nel discreto Sci-Fi Movie "Red Planet".Set 10, 2004

Landing on Titan (3).jpgSaturn, through the fog of Titan123 visiteTitan's surface may hold lakes of liquid ethane and methane, sprinkled over a thin veneer of frozen methane and ammonia. Most of the brownish-orange color comes from more heavily processed hydrocarbons present in Titan's atmosphere and on its surface. Artistic license has been used to exaggerate the size of the orbiter, the sharpness of the icy features, the tilt of Saturn's rings, and the visibility of the planet through Titan's atmosphere.

Landing on Titan (2).jpgLanding on Titan (2)114 visiteThe Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter. The probe is equipped with a variety of scientific sensors to measure the physical properties of the moon's atmosphere; it also carries an imaging device to return pictures of Titan's possibly hydrocarbon-lake-dotted surface.

Landing on Titan.jpgLanding on Titan114 visiteBecause it's in a deep freeze state, Titan's atmosphere is thought to contain chemicals similar to those found on Earth's early days. Data from the Huygens probe combined with Cassini's measurements may offer clues about how life began on Earth. Set 04, 2004

Titan - artwork.jpgHuygens on Titan96 visiteThin methane clouds dot the horizon and a narrow methane spring or "methanefall" flows from the cliff at left and drifts mostly into vapor. Smooth ice features rise out of the methane/ethane lake, and crater walls can be seen far in the distance.Set 04, 2004
