Mars probe to crash to Earth

2011-12-16 14:46
Moscow - A Russian spacecraft bound for a moon of Mars and stuck in Earth's orbit will come crashing back next month, but its toxic fuel and radioactive material on board will pose no danger of contamination, the Russian space agency said on Friday.

Between 20 and 30 fragments of the probe with a total weight of up to 200kg will survive the fiery plunge and shower the Earth's surface, Roscosmos warned in a statement.

The agency said the unmanned Phobos-Ground spacecraft will plummet to Earth between January 6 - 19, and the rough area of where the fragments could fall could only be calculated a few days ahead of its plunge.

While the agency had lost contact with the probe following its launch on November 9, this was the first time they acknowledged that the $170m craft has been lost and will come crashing down.

Since its November launch the engineers in Russia and at the European Space Agency have attempted unsuccessfully to propel it away from Earths orbit and toward its target.

Phobos-Ground weighs 14.6 tons, which includes 12 tons of highly toxic fuel. Experts had warned that if the fuel has frozen, some could survive entry into Earth and pose a serious threat if it falls over populated areas.

But Roscosmos said it is sure that all fuel will burn on re-entry some 100km above the ground and pose no danger.

It said that 10kg of Cobalt-57, a radioactive metal contained in one of the craft's instruments, will not pose a threat of radioactive contamination.

The failed mission was the latest in a series of recent Russian launch failures that have raised concerns about the condition of the country's space industries.
