Pieces of failed Russian Mars probe plunged into mid Pacific

”If anyone gets to see it, it will be a fabulous show”

Pieces of a failed Russian Mars probe plummeted into the Pacific Ocean far off the Chilean coast on Sunday, Russian news agencies cited a military official as saying.

Debris from the Phobos-Grunt craft fell into the sea some 1,250 km west of the coastal island of Wellington, state-run RIA and Itar-Tass cited Aerospace Defence Forces spokesman Colonel Alexei Zolotukhin as saying.

The spacecraft never made it out of Earth's orbit after its November launch on a rare interplanetary mission for Russia's struggling space program. It was not immediately clear whether all the parts of the craft that did not burn up in the atmosphere had fallen in the same area.

Russia's space agency Roskosmos had said debris from its doomed 14-ton craft, which included 11 tons of toxic rocket fuel, might fall in the Atlantic Ocean about midway between Brazil and West Africa.

Due to constant changes in the upper atmosphere, which is strongly influenced by solar activity, the exact time and place of the probe's return had been unknown.

Experts said the falling space junk posed little risk, with the probe's aluminium fuel tank expected to burn up high in the atmosphere.

“If anyone gets to see it, it will be a fabulous show. I don't think there has been an explosion of such a large volume of fuel in space history,” Igor Marinin, editor of a space journal published by Roskosmos, said earlier on Sunday.

The 165-million dollars spacecraft, designed to retrieve soil samples from the Martian moon Phobos, was meant to be Russia's first successful interplanetary mission in over two decades.

But it became stuck in orbit after a botched launch on November 9, and had since been slowly losing altitude due to gravity's pull.

Some 20 to 30 small pieces of debris with a total weight of 200 kg could hit Earth, Roskosmos said, adding that a tiny radioactive cargo of Cobalt-57 was too small to cause harm.

One component likely to survive re-entry was a small return capsule specifically designed to crash-land back on Earth in 2014, mission scientist Alexander Zakharov said.

“This is the capsule that was meant to bring back samples from Phobos, it's disappointing,” Zakharov said. “We're hoping Roskosmos will approve a new craft to accomplish this mission.”

Phobos-Grunt was one of five botched launches last year that marred celebrations of the 50th anniversary of Yuri Gagarin's pioneering first human space flight and hurt Moscow's pride.
