To say Japan's not doing its hardest to monitor and control the radioactive situation at TEPCO in Fukushima is complete bollocks. Japan's already sent in a bunch of robots to scope out the situation, but sending in a rover designed for missions on the moon? Jeez.
Despite having 55 unwavering and brave troopers, certain parts of the damaged nuclear plants in Fukushima are still unsuitable for humans to examine. According to DigiInfo, Japan is considering sending in the Tri-Star IV into the plants. Originally developed to collect rock samples from the moon, the Tri-Star IV's light and simplistic design along with its sheet metal and canvas wheels would be more than capable of overcoming any rugged terrain.
Professor Shigeo Hirose, developer of the Tr-Star IV thinks that it can be used to get over rubble, climb stairs and approach the reactors. It's simple structure would also allow it to be cleaned easily — a problem that arises upon the return of complex robots from dangerous zones.
If sending in a lunar rover will help assess the situation quicker, then I say do it. Who knows when the next time mankind will be returning to the moon will be anyway.
