Details:
February 15,2015 is two years anniversary of Chelyabinsk asteroid event.
After the asteroid exploded the fragments traveled through the atmosphere on their own. Most material has melted completely, but some survived. Thousands of tones reached the ground, and became known as Chelyabinsk meteorites. The scientists studied them and found out they belong to the most common meteorites: ordinary chondrites. During their flight they melted and developed shiny black fusion crust. Some got shaped by an aerodynamic forces and display features of the flight orientation.
Some meteorites broken windows, hit cars and even persons, but most of them fell in the snow, which made a recovery of them relatively easy. Locals including children quickly realized that to find a meteorite they should look for small holes in the snow, and then to dig it, and then there was either a meteorite or a mouse. Interestingly enough the meteorites found 2-3 days after the fall were located atop of small ice pinnacles. The entire families form kids to grandparents suddenly became meteorite hunters. They got two great weeks of hunting before a new snow fell and covered the magic holes. After that the hunting resumed by the end of April after the snow melted.
The image is of a 24.7 grams oriented Chelyabinsk meteorite. It is a dome-shaped meteorite that displays some flow lines, which developed during it passage through the Earth's atmosphere as the molten material flowed towards the trailing edge of the stone.
