Russia’s Phobos-Grunt, whose mission to a Martian moon went astray before circling the Earth, has finally plunged into the Pacific Ocean, says Russia’s Defense Ministry. But experts from Russia’s aerospace industry insist it hit the Atlantic Ocean.
The stray probe plunged into the cold waters of the Pacific Ocean at 17:45 GMT (21:45 Moscow time), says the press service of Russia’s Aerospace Defense Forces in the Defense Ministry.
“Phobos-Grunt’s fragments were to fall into the waters of the Pacific Oceans at 21:45 Moscow time. This is according to the calculations made in the Space Control Centre,” said Aleksey Zolotukhin, of the space division of Russia’s Defense Ministry.
The probe hit the water 1250 km (776 miles) to the west of the Chile’s island of Wellington, in an area commonly used to dispose of “Progress” spaceships once they have completed their missions.
This would be in line with the forecast Russia’s space authority, Roscosmos, made on Saturday.
But a source from Russia’s aerospace industry citing ballistic data has stated the probe landed in the Atlantic, reports RIA Novosti news agency.
“The probe’s fragment fell in an area in the Atlantic Ocean, with the coordinates of 310.7degrees east longitude and 18.2 degrees south latitude in the vicinity of the Brazilian coast,” said the source, adding that Phobos-Grunt re-entered the atmosphere at 17:59 GMT(21:59 Moscow time).
Roscosmos challenged this statement.
“The probe would simply not make it to the Atlantic. Taking into account its orbit, the probe would have gone over Argentina and Brazil,” they stressed.
There were no immediate reports from the two countries whether they had registered the stray probe in their skies.
Till the very last moment there was still some doubt as to where Phobos-Grunt would end up. Sunday’s forecasts put forward Brazil and Argentina as possible destinations.
Roscosmos officials explained the variety of reports by “a decrease in the height of [the probe’s] orbit, solar activity and the state of the atmosphere.”
The 13.5-ton Phobos-Grunt was launched from Baikonur Cosmodrome in Kazakhstan on November 9 to investigate Phobos, one of the moons of Mars. However, after entering Earth’s orbit, the probe failed to launch on its course to Mars and remained stuck going around the Earth.
