Russian space probe to crash to Earth within hours
None
A failed Russian probe designed to travel to a moon of Mars but stuck in Earth orbit will come crashing down within hours, likely in a shower of fragments that survive the fiery re-entry.
The unmanned Phobos Ground is one of the heaviest and most toxic space derelicts ever to crash to Earth, but space officials and experts say the risks are minimal as its orbit is mostly over water and most of the probe's structure will burn up in the atmosphere anyway. (AP)
