Japan's Hayabusa 2 spacecraft reaches cosmic 'diamond'
A Japanese spacecraft has arrived at its target: an asteroid shaped like a diamond or, according to some, a spinning top. Hayabusa 2 has been traveling toward the space rock Ryugu since launching from the Tanegashima spaceport in 2014. Using explosives to propel a projectile into Ryugu, it will dig out a fresh sample of rocks and soil from beneath the surface and deliver them back to earth. (BBC)
DARPA is literally reinventing the wheel
The advanced research arm of the United States Department of Defense, DARPA, wants to rethink how military vehicles are designed to protect the crews inside -- by making them faster and smarter. The program, called GXV-T, seeks to reduce combat vehicles’ size and weight while doubling their speed and making them capable of traveling across 95 percent of all imaginable road and off-road surfaces on earth. It involves several different technologies, including augmented reality and LIDAR but, perhaps most intriguingly, the GXV-T team is also developing entirely new types of wheels that will allow soldiers to escape dangerous situations faster.

That made 2017 the second-worst year for tropical tree cover loss in the satellite record, just below the losses in 2016. (New York Times)
