Comets-Comet_Hartley_2-NASA-0.jpgComet "Hartley 2" (an Image-Mosaic by NASA, JPL-Caltech, UMD, EPOXI Mission)90 visiteDa "NASA - Picture of the Day" del giorno 5 Novembre 2010:"Follow these 5 frames clockwise starting from the top left to track the view from the EPOXI Mission Spacecraft as it approached, passed under, and then looked back at the nucleus of comet Hartley 2 on November 4.
Its closest approach distance was about 700 Km. In fact, this encounter was the 5th time a spacecraft from planet Earth has imaged a comet close-up. But Hartley 2's Nucleus is definitely the smallest one so far, its long axis spanning only about 2 Km (such as approx. 1,2 miles).
Though Hartley 2 is small, these stunning images showing Jets of Dust and Gas indicate an impressively active surface. The Jets are seen originating from the rough surface areas, with Sunlight illuminating the Nucleus from the right. Remarkably, rough areas at both ends of the elongated Nucleus are joined by a narrower, smooth waist.
The EPOXI mission reuses the Deep Impact Spacecraft that launched a probe impacting the Nucleus of comet Tempel 1 in 2005".MareKromium11/07/10 at 20:53MareKromium: ...Stile espressivo NASA, nulla di pił.

Asteroids.jpgAsteroids (an Image-Mosaic by Emily Lakdawalla - Planetary Society - & Ted Stryk)105 visiteDalla Rubrica "NASA - Picture of the Day" del giorno 26 Luglio 2010:"As humans explore the Universe, the record for largest Asteroid visited by a Spacecraft has increased yet again. Earlier this month, ESA's robotic Rosetta Spacecraft zipped past the asteroid 21 Lutetia taking data and snapping images in an effort to better determine the history of the Asteroid and the origin of its unusual colors.
Although of unknown composition, Lutetia is not massive enough for gravity to pull it into a sphere.
Pictured above on the upper right, the 100-Km across Lutetia is shown in comparison with the other nine Asteroids and four Comets that have been visited, so far, by human-launched spacecraft. Orbiting in the Main Asteroid Belt, Lutetia shows itself to be a heavily cratered remnant of the early Solar System.
The Rosetta Spacecraft is now continuing onto comet Churyumov-Gerasimenko where a landing is planned for the AD 2014".MareKromium07/29/10 at 14:03andreagg: infatti scherzavo! ;)
