Russian spacecraft discharges 12 tons of poison to the ground?

Russia's spaceship launched on Mars failed to roam Earth's orbit with 12 tons of toxic fuel.

According to AP , the worse news is that Phobos-Grunt could fall back to the ground in the next few weeks, if Russian engineers could not reconnect with it before tomorrow. They also hope that the fuel on the ship will explode on the upper atmosphere and not threaten the ground.

The $ 170 million unmanned aerial ship called Phobos-Grunt with the mission to explore Mars is launched from Kazakhstan. After separating from the boosters, according to the plan, the ship's engines will have to activate twice to overcome the attraction of the Earth and escape to Mars.

Even so, disaster has occurred when no engine has 'spoken' . Consequently, the ship could not leave Earth's orbit and was hovering at a height of 129 - 212 miles above the ground. And according to American satellite observations, it seems that this orbit is getting lower and lower.

The Russian Federal Space Office predicts that the ship's trajectory and on-board fuel allow it to circumnavigate the Earth for about two weeks. Vladimir Popovskin, director of the agency, acknowledged that the ship maintenance system was in the right direction, probably broken. The 'rescue' ship of Russian engineers is struggling to pile up because of the limited communication network between the ground and the ship.

In fact, it is the amateur astronomers who are the first to discover the problem with the Phobos-Grunt when they find that the ship is still stuck in the atmosphere.

Even so, Mr. Popovskin still hopes this is only a fixable software bug and the system can be recovered.

According to data from the Russian side, the ship weighs about 14.6 tons but most of its weight (12 tons) is fuel. The key issue is that this fuel is still in liquid form or has been frozen. If it was liquid, it would ignite harmlessly when it was 80km above the ground.

But if the ship's fuel is frozen, the risk of harming the Earth will be greater, because these toxins will pass through the fire wall and fall to the ground. With nitrogen tetroxide and hydrazine, this will be the "most toxic satellite ever".

In 2008, also because of concern about the level of poisoning of a dead satellite (although the satellite's titanium fuel tank contains only about half a ton of frozen hydrazine), the US government ordered the shooting down by name. Navy fire.
