Russia's Mars dream ends, and now a toxic nightmare begins as its crippled fuel-filled probe heads back down to earth

Russia's Mars dream ends, and now a toxic nightmare begins as its crippled fuel-filled probe heads back down to earth | Mail Online: "Russia's space agency has all but given up hope of saving a £100million spacecraft that was bound for Mars but conked out shortly after launch. Engineers had three days to fix a problem that caused the Phobo-Grunt probe to shut down before batteries aboard the craft died for good. The engines that were supposed to propel it on its way to the red planet failed to ignite, and any attempts to correct the failure seemed doomed when scientists admitted that they couldn't even establish communications with the craft."
