A Russian space probe aiming to land on a Mars moon was stuck circling the Earth after equipment failure Wednesday, and scientists raced to fire up its engines before the whole thing came crashing down. One U.S. space expert said the craft could become the most dangerous manmade object ever to hit the planet. If the controllers fail to bring the Phobos-Ground back to life, the tons of highly toxic fuel it carries would turn it into the most dangerous manmade object ever to fall from orbit. |
