Mission launched to retrieve Fukushima reactor debris

Japanese officials launched a mission to retrieve melted fuel debris from the Fukushima Daiichi nuclear plant, using a remote-controlled robot named "telesco." The operation aims to collect a fragment weighing less than a tenth of an ounce from the reactor, where an estimated 880 tons of radioactive material remains. The cleanup is projected to take 30 to 40 years, amid ongoing challenges and scrutiny.
