“I know I may not make it through this lunar night.” The China Academy of Space Technology laid the pathos on thick when it gave its lunar robot Jade Rabbit a farewell speech at the end of last month. The rover had become mired in moon dust and was unable to enter hibernation. Facing 14 days without sunlight, the solar-powered robot, launched on 2 December, was unlikely to survive. “Good night, Planet Earth,” it said. “Good night, humanity.”
It looked like the end of a venture that could have accelerated the process of finding out who – if anyone – owns the moon. The ultimate goal for Jade Rabbit was to bore a hole in the moon and see what moon rock is made of. That’s because the Chinese think the moon’s minerals might be worth extracting. “They are looking at feasibility for mining the moon, and they are likely to do it if there’s a strong business case,” says Richard Holdaway, director of the space division at the UK’s Rutherford Appleton Laboratory, which collaborates closely with China’s space programme.
