THE DAWN MISSION..
Click HERE for more information..
WHAT IS THE DAWN MISSION?
The Dawn mission will study the asteroid Vesta and dwarf planet Ceres, which are celestial bodies believed to have been formed by the effect of gravity pulling together surrounding objects and gases, early in the history of the solar system. Data returned from the Dawn spacecraft could provide opportunities for significant breakthroughs in our knowledge of how the solar system formed.
What Is The Objective Of The Mission?
During the earliest epochs of our solar system, the materials in the solar nebula varied with their distance from the sun. As this distance increased, the temperature dropped, with terrestrial bodies forming closer to the sun, and icy bodies forming farther away. The Dawn mission will characterise the early solar system and the processes that dominated the formation of such bodies.
Why Vesta And Ceres?
The asteroid Vesta and the dwarf planet Ceres have been selected because, while both have conditions and processes that were depicted early in the formation of the solar system, they developed into two different kind of bodies. Vesta is a dry, differentiated object with a surface that shows signs of resurfacing. It resembles the rocky bodies of the inner solar system, including Earth. Ceres, by contrast, has a primitive surface containing water-bearing minerals, and may posses a weak atmosphere. By studying both these two distinct bodies the Dawn mission hopes to compare the different evolutionary path each took and also create an overall picture of the early solar system
DAWN'S JOURNEY:-
Launch: September 27, 2007
Vesta Arrival :August 2011
Vesta Departure: May 2012
Ceres Arrival: February 2015
End Of Primary Mission: July 2015
