 Here we see pictures of the near-Earth asteroid 162173 Ryugu, taken by the Japan Aerospace Exploration Agency spacecraft Ayabusua-2. It's a potentially hazardous asteroid discovered in 1999. It's approximately one kilometer, or six-tenths of a mile, wide. And its mass is estimated to be around 450 million tons. This spacecraft was launched in 2014 and arrived at the asteroid on the 27th of June, 2018. Here you can see the spacecraft's shadow on the asteroid. The mission includes four rovers that will land and explore the surface. By September 22, two of them had successfully touched down on Ryugu's surface. Our objective is to explore for the asteroid's minerals, water, and organic matter, in a bid to learn about the origin and evolution of the solar system. The mission is also expected to return material from the asteroid to Earth by the end of 2020.
