Phobos-Grunt Re-entry Map
The first major space-related event of 2012 is upon us. The failed Russian Mars probe, Phobos-Grunt, crash landed today in the Pacific Ocean – or was it the Atlantic Ocean? After months of speculation, even the experts seem to disagree about the final resting place of the doomed satellite. The Russian Ministry of Defense, and according to some accounts, U.S. Strategic Command, are reporting the satellite fell into the Pacific Ocean to the west of Chile and Argentina.
“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, a representative from the Russian Defense Ministry’s space office.
Others, including Russian scientists and leaders in Russia’s aerospace industry, are claiming Phobos-Grunt actually landed in the Atlantic Ocean, northeast of Brazil.
“The probe’s fragment fell in an area in the Atlantic Ocean, with the coordinates of 310.7 degrees east longitude and 18.2 degrees south latitude in the vicinity of the Brazilian coast,” claimed an unnamed source.

Launched in November 2011, the satellite was on a mission to explore Phobos, one of two moons orbiting Mars, but stalled in low-Earth orbit gradually falling back toward the Earth’s surface. The mission, which was supposed to last three years, was an ambitious step forward for Russia’s space agency Roscosmos. If successful, Phobos-Grunt would have been the first ever spacecraft to return to Earth with soil samples from the moon of another planet. The Planetary Society, an NGO based in California which is expected to make headlines later this year for its efforts advancing commercial space exploration, also loaded Phobos-Grunt with a variety of bacteria to test whether or not life could ever “planet-hop.” All in all, Russia spent nearly $170 million on the failed Phobos-Grunt mission.
Regardless of the exact re-entry point, what exactly do we need to do (or not do) when a satellite comes crashing down? Here’s a “beginner’s guide” to surviving a space junk re-entry event. It’s worth a quick glance given the sudden increase in falling satellites. Interestingly, the legal implications highlighted in the guide (No. 7, “Be aware of the legal situation”) state that the 1967 Outer Space Treaty and 1972 Space Liability Treaty require the launching state to pay compensation for any (physical) damage resulting from a crash. So in the event Phobos-Grunt, or future space junk crashes, cause damage here on Earth, it will be the responsibility of the launching state to pay for repairs. That said, there is not much of a chance for bodily injury, so there is no need to run out and get space insurance just yet. The chances of any one person being hit by a falling satellite are extremely rare.
More seriously, what caused this failure? After all, this was suppose to be Russia’s major Mars-related mission. With the failure of this Phobos-Grunt, NASA’s Curiosity rover, which is already well on its way to the Red Planet, will continue to give the United States the upper hand in terms of Mars exploration.
According to an interview this week, Vladimir Popovkin, head of Roscosmos, says (to the surprise of many) foul play cannot be ruled out as a factor. “We don’t want to accuse anybody, but there are very powerful devices that can influence spacecraft now,” Mr. Popovkin said. “The possibility they were used cannot be ruled out.” Slate.com provides us with another quote from the interview, which was given in Russian to the newspaper Izvestia and translated by various sources, “the frequent failure of our space launches, which occur at a time when they are flying over the part of Earth not visible from Russia, where we do not see the spacecraft and do not receive telemetric information, are not clear to us.”
Mr. Popovkin did not directly accuse the United States, or any other country, of foul play and was most likely blowing off steam after a series of failed launches this past year. In the same interview, Mr. Popovkin also acknowledged that the failure was more likely related to aging technology. “If we had not sent it to Mars in 2011, we would have had to throw it away.”
According to ABC News, “in the half century since the space age began, Russia has tried and failed 19 times to reach Mars.”
