Review:
Jaxa Hayabusa Asteroid Missions
overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
The JAXA Hayabusa asteroid missions comprise a series of Japanese space endeavors aimed at studying, retrieving samples from, and returning material from asteroids. The original Hayabusa (MUSES-C) mission launched in 2003 successfully collected surface samples from asteroid Itokawa in 2010, marking a significant milestone in planetary exploration. The subsequent Hayabusa2 mission, launched in 2014, targeted asteroid Ryugu and delivered valuable data and samples back to Earth in 2020. These missions have advanced our understanding of small bodies in the solar system and contributed to planetary defense research.
