Tomorrow, as of writing, on Wednesday, June 27, Japan will arrive.
Launched by Japan in December, 2014, JAXA will arrive at the near-earth asteroid Ryugu and study it for 18 months. Moreover, they will bring a sample of the asteroid back to Earth in 2020. Read more about the Hayabusa2 mission here.
This is not the first time this has happened, surprisingly. The mission is a follow-up of Hayabusa, which returned samples of Asteroid 25143 Itokawa to Earth in 2010 despite numerous technical difficulties.
