The Morning After: A surprising cloudy day on Mars

NASA's Curiosity rover has been able to register something which, while unremarkable on Earth, is an interesting phenomenon for Mars -- cloudy skies. The agency has shared images of "shining" clouds, able to form on a planet that has a relatively thin atmosphere. Nothing has been confirmed just yet, but they could be naturally formed dry-ice clouds, made of carbon dioxide. It might not match the appeal of ancient megafloods or possible signs of life, but Curiosity continues to offer up new Mars insights, both above and below the surface of the red planet. A little closer to home, Japan's Aerospace Exploration Agency (JAXA) has teamed up with Sony, Doshisha University and toy-maker Tomy on a ball-shaped transforming robot destined for the Moon.
