Japan delays landing of Hayabusa2 probe on asteroid
The Japanese Hayabusa2 spacecraft's landing on asteroid Ryugu has been delayed until January, due to the asteroid's rugged surface, as per data received by space agency JAXA. The spacecraft recently dropped a pair of round, tin-shaped robot rovers and a new 10-kilogram observation robot, MASCOT, on the asteroid. It is expected to return to Earth with samples in 2020.
