  • Next week the Canadian Space Agency will launch the world's first dedicated asteroid-hunting satellite-just after one of the hottest events in space rock history: a surprise meteor that exploded over Russia on 15 February. The Canadian telescope has been years in the making, so it is pure chance that it will blast off hard on the heels of that big event. Researchers at Ural State University in Yekaterinburg say they have recovered meteorite fragments from Lake Chebarkul and determined that they are ordinary chondrites. Although this is the most common type of rock in space, such meteorites look a lot like terrestrial rocks, so they are difficult to recognize and rarely collected.
