The Japanese space probe Hayabusa 2 dropped an exploratory robot onto the surface of the asteroid Rguyu early on Wednesday morning. The autonomous probe is called MASCOT. With 16 hours of battery life, it landed at one spot on the asteroid's southern hemisphere, took a slew of data and then jumped to another location for more image-taking, temperature and magnetic measurements and chemical analyses of the rocks. MASCOT project manager is Dr Tra-Mi Ho of the German Space Agency.

A critical meeting of the International Panel on Climate Change is underway in South Korea.
