A remote-controlled robot has embarked on its second mission to retrieve tiny bits of melted fuel debris from inside a damaged reactor at the Fukushima nuclear plant that was wrecked by a tsunami 14 years ago.

The mission, which follows the first such debris retrieval in November, is aimed at eventually developing the technology and robots needed for a larger scale clean-up of the plant, destroyed by the earthquake and tsunami in March 2011.
