Russian Poison From The Sky

This time, it’s the Russian’s turn to randomly drop a spacecraft to Earth from orbit, only this one is loaded up with ten tons of highly toxic chemicals. When you duck, don’t forget your umbrella.

Toxic Russian Mars Probe Heads Back to Earth

It’s hard to believe that only last week we were getting excited for Russia’s first interplanetary mission in 15 years to launch. By now, we should be happy in the knowledge that the ambitious — and awesome — mission is powering through space, toward the Martian moon Phobos.

The reality is that we are now discussing uncontrolled reentry scenarios.

As if that wasn’t enough bad news, we are looking at an uncontrolled toxic reentry scenario. Phobos-Grunt — correctly written “Fobos-Grunt,” meaning “Phobos-Soil” or “Phobos-Ground” — is fully-laden with unsymmetrical dimethylhydrazine and nitrogen tetroxide; that’s ten tons of fuel and oxidizer. The probe itself weighs-in at only three tons.

The majority of the fuel will likely vaporize during reentry, but everyone will be hoping for a splash-down in an ocean (which covers two-thirds of Earth, fortunately), as the wreckage will still be hazardous. There’s also a small quantity of radioactive cobalt-57 in one of the science missions housed in the probe — a fact that will most likely cause a media frenzy.

It is for these reasons that the Russian media is dubbing Phobos-Grunt “Most toxic falling satellite ever.”

Man, the Russians just can’t catch a break. This is their fourth launch failure just this year and now they’re 0 for 18 at Mars missions.
