하야부사 is a series of Japanese space missions conducted by JAXA, the Japan Aerospace Exploration Agency. The first mission, 하야부사 1, launched in 2003, successfully collected samples from the asteroid Itokawa and returned them to Earth in 2010. This marked a significant achievement in asteroid exploration. The second mission, 하야부사 2, launched in 2014, targeted the asteroid Ryugu. It successfully collected samples and returned them to Earth in December 2020. Both missions have provided valuable insights into the formation of the solar system and the composition of asteroids.
