"A European satellite that mapped Earth’s gravitational field in exquisite detail will be pulled down by gravity to its fiery destruction sometime in the next few days. Where and when it will crash no one knows. It could be almost anywhere on the globe. About 25 to 45 fragments of the one-ton spacecraft are expected to survive all the way to the surface, with the largest perhaps weighing 200 pounds. It is the latest in a parade of spacecraft falling from the sky in what are worryingly called ‘uncontrolled entries.’ About 100 tons of debris will fall from the sky this year alone."
