China's Jade Rabbit (Yutu) successfully came back from the dead after a serious malfunction in 2014. (*see update below) Scientists have finished analyzing the data China's moon rover Yutu beamed back sometime ago. As it turns out, the rocks the Jade Rabbit collected can reveal more about the moon's younger years when there were small volcanic eruptions all over the place. See, the Chang'e-3 probe that served as its ride to the moon in 2013 landed on a "relatively young" impact basin visible from Earth, giving Yutu the chance to collect samples that are only 3 billion-years-old. The samples brought back by the Apollo missions were as old as 4 billion years.
