China’s first-ever moon rover is driving on the lunar surface after successfully separating from its carrier lander to begin exploring its landing locale: the Bay of Rainbows.

The Chang’e 3 lunar lander reached the moon Saturday (Dec. 14) at about 9:12 p.m., Beijing time, making China only the third country in the world to achieve such a moon feat after the former Soviet Union and the United States. The lander also delivered the robotic rover Yutu (“Jade Rabbit”) to the lunar surface to begin its months-long driving mission.

A few hours after landing, Yutu’s wheels were unlocked by the firing of explosive devices and the rover unfolded its solar wings and deployed its instrument-laden mast. A cable connecting the rover and lander was then cut. A “transferer” system — resembling a pair of ladders set up on the lander —then unlocked to inch down closer to the lunar surface, allowing the Yutu rover access to the moon’s surface to begin its lunar trek.

NASA scientists found faint signatures of water in the atmospheres of five distant planets. All five planets appear to be hazy.

NASA’s Hubble Space Telescope has detected water in the atmospheres of five planets beyond our solar system, two recent studies reveal.

The five exoplanets with hints of water are all scorching-hot, Jupiter-size worlds that are unlikely to host life as we know it. But finding water in their atmospheres still marks a step forward in the search for distant planets that may be capable of supporting alien life, researchers said.

“We’re very confident that we see a water signature for multiple planets,” Avi Mandell, of NASA’s Goddard Space Flight Center in Greenbelt, Md., lead author of one of the studies, said in a statement. “This work really opens the door for comparing how much water is present in atmospheres on different kinds of exoplanets — for example, hotter versus cooler ones.”
