China has launched the first mission to land a robotic craft on the far side of the Moon, Chinese media say.
The Chang’e-4 mission will see a static lander and rover touch down in Von Kármán crater, located on the side of the Moon which never faces Earth.
The payload blasted off atop a Long March 3B rocket from Xichang Satellite Launch Center.

A new way to make arrays of nanofibers that gets its inspiration from polar bear fur, lotus leaves, and gecko feet could lead to coatings that are sticky, repellant, insulating, or light emitting.
“This is so removed from anything I’ve ever seen that I would have thought it was impossible,” says Joerg Lahann, a professor of chemical engineering at the University of Michigan and senior author of the paper, which appears in Science.
Polar bear hairs are structured to let light in while keeping heat from escaping. Water-repelling lotus leaves are coated with arrays of microscopic waxy tubules. And the nanoscale hairs on the bottoms of gravity-defying gecko feet get so close to other surfaces that atomic forces of attraction come into play.
