The Sky Is Falling

COSMOS IS FALLING: The first fragments of shattered satellite Cosmos 2251 are about to reenter Earth's atmosphere. According to US Strategic Command, fragment 1993-036PX will reenter on March 12th, followed by 1993-036KW on March 28th and 1993-036MC on March 30th. These are probably centimeter-sized pieces that will disintegrate in the atmosphere, posing no threat to people on the ground.
