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. From a report: Hayabusa 2 has been travelling toward the space rock Ryugu since launching from the Tanegashima spaceport in 2014. It is on a quest to study the object close-up and deliver rocks and soil from Ryugu to Earth. It will use explosives to propel a projectile into Ryugu, digging out a fresh sample from beneath the surface. Dr Makoto Yoshikawa, Hayabusa 2's mission manager, talked about the plan now that the spacecraft had arrived at its destination. "At first, we will study very carefully the surface features. Then we will select where to touch down. Touchdown means we get the surface material," he told me. A copper projectile, or "impactor" will separate from the spacecraft, floating down to the surface of the asteroid. Once Hayabusa 2 is safely out of the way, an explosive charge will detonate, driving the projectile into the surface.
