NASA spacecraft is about to close

The Deep Impact probe spacecraft of the US Space Agency (NASA) will approach the Comet Hartley 2 with the closest distance so far on November 4, NASA scientists batched.

The US space agency (NASA) launched the Deep Impact spacecraft into space to track stars Hart Hartley for the past two months. On November 4, Deep Impact will approach this star with an extremely close distance of 698 km.

Star image Broom Hartley 2 was taken by Hubble telescope on September 25, 2010.

The result of the very close approach of the Comet Hartley 2 will help scientists better understand the structure and evolution of Comet, as well as the secrets of the early solar system. Earlier, on the night of October 20, the star Hartley 2 approached Earth at the closest distance since it was discovered to date of 17.7 million kilometers.

' The ability of Deep Impact to reach the Star Hartley 2 at close range could help scientists discover more secrets about this Comet, ' said Dr Tim Larson, executive director of Deep Ship's mission. Impact, said.

The Comet Hartley 2 is about 1.5 km long and the orbital cycle revolves around its Sun for 6.5 years, stretching from outside Jupiter's orbit to near Earth's orbit. Austrian astronomer Malcolm Hartley discovered this Comet star in March 1986.

It is known that since being launched into space to monitor the star Comet Hartley 2, the Deep Impact spacecraft sends 2000 images of this broom to Earth every day.
