NASA DAWN Mission: UFO Crash Site on Giant Asteroid Vesta 2011

On the asteroid Vesta, someone dug mines!

They found a long trough of unknown origin.

Probe Dawn («Dawn") continues to explore and photograph the asteroid Vesta. The spacecraft approached him about a month ago. It was a momentous event in the study of the universe. After all, never probe from Earth did not become an artificial satellite of asteroid.

Recall that the West - is a giant denizen of the Main asteroid belt located between Mars and Jupiter. The average diameter of Vesta is about 530 kilometers. Under this option, it is second only to Pallas, who wears the title of the largest asteroid (average diameter of 532 kilometers). However, the mass of Vesta Pallas superior, being the heaviest asteroid. Such large bodies were created in the asteroid belt between Mars and Jupiter, about four billion years ago, ie in the early stages of the solar system. Therefore, astronomers, and it is interesting: Vesta may shed light on many mysteries of the universe.
July 19 "Dawn" made the first detailed picture of the ward. August 3 at the new close-up photographs of the testers, hoping to find signs of life on an asteroid in the form of the presence of water, suddenly saw a clear figure of "snow woman." Although, of course, it was only three nearby crater, which is covered with the surface of Vesta. Each of them is smaller than the other, because of what the picture really looks like from afar, "snowman".

And today once again surprised the scientists probe. First, before they were confident that the 460-kilometer crater at the south pole of Vesta - the trace of a collision with another celestial body. At least so it seemed in the study of images taken orbiting telescope Hubble.
It is assumed that as a result of the impact fragments were part of the asteroid belt, in part - in interplanetary space, and even appeared on Earth as meteorites. However, a probe made ​​by "Dawn" close-ups show that the giant plain do not like a typical impact crater: a wall of rock thrown around only half its circumference, and the center is not a conical elevation, a rounded hill, reports rnd.cnews.ru.
Second, it seems very strange series of long trenches that surround the equator of Vesta. This is not seen on any other celestial body, and what impact could cause such an effect is not explained.
Chief investigator Chris Russell Dawn believes that this puzzle can be solved in October, after the interplanetary probe will come to the West Side at the closest distance and give clear images and maps of gravitational forces.
Also, planetary scientists are hoping that Dawn would explain why Vesta is the brightest asteroid, reflecting up to 40% of sunlight, and the reason for some of its brighter than others.

On the asteroid Vesta, discovered a giant "snowman" - an anomaly!

The American space probe "Dawn" is sent to Earth photographs of one of the most ancient and mysterious asteroids - Vesta. Astronomers have long been hunted for him, but no one expected to find on its surface "snowman".Satellite-cartographer "Dawn" was trying to find traces of water on the asteroid, there is evidence of life, but ran into a giant snowman. He was, alas, is miraculous - it's a triple crater. The exact dimensions of scientists have yet to figure out.The asteroid Vesta - the brightest in the sky. Such large bodies were created in the asteroid belt between Mars and Jupiter, about four billion years ago, ie in the early stages of the solar system."West - one of the unique instances of such an ancient period of the existence and formation of our system. We are very pleased that we now have the opportunity to get acquainted with a variety of features of the asteroid's surface," - said Christopher Russell, supervisor of the project.Asteroid shape resembles a soccer ball pierced. The most notable feature of the landscape - a huge crater at the south pole, which is certainly a huge scar after a collision with another celestial body. Unusual asteroid discovered German astronomer Heinrich Olbers in 1807. But neither then, nor 20 years ago, when Vesta looked at with a telescope "Hubble", such high-quality images and video all the more scientists were not available."One of the most amazing aspects of this mission is that we had the opportunity to explore one of the most neglected areas of the Solar System. Vesta - this is the only asteroid that can be seen with the naked eye from Earth," - said Marc Rayman, chief engineer of the project.NASA ironically, why not melted snowman, because an asteroid, just as on Earth, it's summer? Now the end of the summer season in the southern hemisphere of Vesta, so a large crater at the south pole of the sun lit up. With this calculation and sent the probe to an asteroid - let the summer there and it lasts more than 11 months.



Is this object artificial? NASA's Dawn spacecraft obtained this image of the giant asteroid Vesta with its framing camera on July 24, 2011. It was taken from a distance of about 3,200 miles (5,200 kilometers). Dawn entered orbit around Vesta on July 15, and will spend a year orbiting the body.
