Why Use White Squash Balls

LIST THE GREAT APPROACH TO COMET HARTLEY 2

The event will take place within just nine days, on 4 November 2010. That's when the mission fighter kites "Deep Impact, the same as in 2005 drove a 400 kg projectile into Comet Tempel 1, passing just 702 km away from their second goal, Hartley 2. Ingenuity will be assumed that the best images from a kite collected so far. And you'll get first-hand on a cold relic and that comes from the distant days when our planetary system formed.

The Hartley 2 comet is a small, only 1.5 km in diameter and makes a complete orbit around the Sun every six years. When you meet with Deep Impact, the comet will be at its peak time, which coincides with its proximity to the sun.

Like the rest of the comet, the orbit of Hartley 2 is very long and goes far from the sun during most of the time, so the approach of November 4th is an extraordinary opportunity to study it. In fact, the action of sunlight vaporizes the top layers of ice core, releasing the real space eruptions of dust and gas.

The objective of the mission is precisely to get as much information as possible about the composition of this comet and compare it with that of other known, will give us new clues about the origin of the sun and its planets. "Comets," says Sebastien Besse, also an astronomer at the University of Maryland, are the leftover building material of our Solar System. " When the planets formed from the rotating solar nebula, countless fragments that do not set out literally thrown toward the outside and became comets.

During the meeting, which will only last one day, the Deep Impact will launch a dive into the bright comet tail and head toward the core, who photographed with high resolution cameras. "We expect to see in great detail the facial features of the comet," says scarred Beese. We may even be able to say exactly where they come from gas jets. "

initially built to fulfill the mission that bears his name, the Deep Impact threw a metal projectile in the year 2005, the comet Tempel 1 , causing a small explosion on its surface that was imaged by spacecraft instruments.

Now the probe is used for other purposes, such as study and track multiple objects and celestial bodies within the mission Extrasolar Planet Observation and Characterization (EPOXY) , the NASA . But researchers have not wanted to miss the chance to make the ship look into this new and interesting surviving building of the Solar System.
