EPOXI Mission - http://epoxi.umd.edu/ 
This is the continuation of space exploration mission Deep Impact, the comet now consider 103P/Hartley 2. And will produce only 700 kilometers of the comet nucleus on November 4, 2010. A very important opportunity for scholars in the field of comets and considering that few have been addressed to date. In 1986 the famous Halley's Comet was the first to be visited up close. And the last mission was in July 2005 between the comet Tempel 1 and the "Deep Impact", which seeks to identify now for the first time this comet surface the presence of these "ice." In a few days, Deep Impact redirected on this new target will give us vitalinformación on 103P/Hartley 2.
Scarmato explains: "This comet is part of the existing number of comets in our solar system, but this is only the fifth time it approaches the Earth and then we have the unique opportunity to photograph and study a comet" young "and find information to provide more knowledge about the birth of our solar system." This means that the probe "will closely follow the appearance of its surface and then see the source of gas and dust emission, and hence deduce its physical and chemical composition."
Often the idea of \u200b\u200bobserving the sky is linked to ancestral fears of the man who, in ancient times was not able to understand many phenomena. The appearance of comets were often associated with catastrophic events or a bad omen, but today we have the right tools to make new considerations.
Comets are balls of ice water in 95% of its composition with other elements in small quantities. Scarmato confirms that "we know enough about what happens when a comet approaches the Sun and Earth."
He continues: "The ice is trapped in a kind of shell carbon, due to the prevailing temperature tends to sublime-step solid to volatile. This phenomenon gives rise to the "coma" and "tail" of the comet that extends in a direction opposite to that in which it is the sun. "What seems to be interesting to study further the dynamic evolution of tag compounds emitted by this comet, the 103P/Hartley 2 "." You can help us understand some of the events that happened on Earth billions of years ago. " "For example, Scarmato says that the extinction of the dinosaurs seems to be attributed to the fall of a large comet or an asteroid perhaps."
Astrophysical Toni Scarmato is a graduate of the University of Bologna. He resides in San Costantino di Briatic, Calabria, Italy. Astronomer is a member of the Italian Union and collaborator Astrophysics at NASA. He is recognized internationally and its 1,000 th comet discovery through satellite observatory SOHO (Solar Heliospheric Observatory).
