Phobos-Grunt on the Run to hit Earth

Satellite Phobos-Grunt will hit Earth in early 2012, around January 12, 2012 approximately 5.5 days. The fall of Phobos-Grunt is not the first. Earlier there was Upper Atmosphere Research Satellite (UARS) belonging to NASA and the Roentgen Satellite (Rosat). Phobos-Grunt is more than 13 tons, twice the UARS. Secondly,
there is the Phobos-Grunt who is designed to be very resistant to heat while turning to Earth intact.

Larger mass and the presence of heat-resistant materials will impact the amount of debris that reaches the Earth's surface, which is estimated to be greater.

The third, most of its mass in the form of hydrazine, a rocket hipergolik materials are extremely toxic to humans. Currently estimated hidrazinnya has changed so frozen due stranded in Earth orbit. However, when falling into the Earth's surface opens the possibility of residual liquid hydrazine is still there. Phobos-Grunt is a Russian mission to land on Phobos, moon of Mars. This media is in charge of taking samples of Phobos soil and rocks and bringing them to Earth. Therefore, a vehicle equipped with heat resistant material. Phobos Grunt mission cost about Rp 1.5 trillion. The failure of Russia to send mission to Phobos is the umpteenth time, after being failed in 1988 and 1996.
