"Sometime this weekend, Phobos-Grunt will crash into the Indian Ocean. The Russian space probe was supposed to return a sample from Mars's moon Phobos (hence the name - grunt means "ground" in Russian). But after its launch on 9 November, the upper stages failed, and it remained stuck in low Earth orbit - so low that atmospheric drag will destroy it."
