Not since an enormous quake (and subsequent explosions) crippled the Fukushima plant has anyone stepped foot insideā€”the radiation has been too thick for humans, leaving robots to do the job. But not today, as workers braved the millisieverts.

After the robot squad reported lowered radiation levels, a team of twelve, working on quick shifts to prevent over-exposure, entered the plant's leaking reactor to repair an urgently-needed ventilation system. Should it prove successful, the functioning ventilator will allow for more manned missions inside the plant, as radiation levels diminish furtherā€”an important path towards (safely) shutting the place down for good.
