Canada is just one of many countries that are closely monitoring a wayward Russian satellite that is expected to make a fiery return to Earth on Sunday. The 15-ton Phobos-Grunt satellite has been circling the planet out of control since its Nov. 8 launch.
Its rocket boosters failed to send it on its planned voyage to Mars.
Roscosmos, the Russian space agency, predicts the car-sized satellite will re-enter the atmosphere on Sunday. It could come down anywhere in an area stretching as far north as Calgary and as far south as the tip of South America.
