On the Vesta there are many water ice
For the asteroid Vesta, the scientific world is watching more than a dozen years, many have learned even more left. Something cooked, but it`s the little things:) Vesta is a unique object in deep space, it is unique for many reasons. This is probably one of the largest asteroids in the asteroid belt, if in the future I will find even more significant, it will be the big discovery of the 21st century. The asteroid is very peculiar, the scientific world of his with great curiosity examines and explores what is not the year, then something new in this direction published. Found the lump quite by accident, was just looking for another planet between Mars and Jupiter, and as a result found only debris in the asteroid belt.
Vesta is unique in that its surface is smooth as a skating rink for a long time the scientific world has come up with an explanation for this has not yet guessed and not revealed the secret. The answer was more than just the surface of Vesta is covered with a thick layer of frozen water. Figured it out after analyzed data from the Dawn probe , this device was around in 2011 and 2012. On Board the probe had enough equipment to get the answer to the question "Why is the surface on the Vesta side so smooth?". Using locator and neutron detector scientists to enlighten the entire surface and have now pretty accurate structural map of the surface of the asteroid. It turns out that there where a smooth surface in the upper layers of the surface a lot of hydrogen. That explains all, with high probability, all the smooth places on the Vesta it is the ordinary ice fields, frozen water. The Dawn probe was designed to study Vesta, he successfully got to her and did much useful work for the study of all that is caught in the grip area of sensors and devices. Dawn is also very well studied asteroid belt between Jupiter and Mars, so with high probability it can be argued that there are no more big asteroid, something larger than Vesta and Ceres.
