Japan’s Hayabusa2 Is Chasing an Asteroid for a 2031 Landing, but New Data Spells Trouble

The article discusses the challenges faced by Japan's Hayabusa2 mission, which is planning to land on the asteroid 1998 KY26 in 2031. Recent observations have revealed that the asteroid is much smaller and spinning faster than initially believed, which could complicate the mission. The original estimates suggested that 1998 KY26 was about 30 meters in diameter, but new data indicates it is only around 10 meters wide. Additionally, the asteroid is spinning much faster than expected, completing a full rotation every 10 minutes. This rapid spin could make it difficult for the Hayabusa2 spacecraft to land and collect samples. The article highlights the importance of accurate data in mission planning, as the new information about 1998 KY26's size and rotation rate has forced the Hayabusa2 team to re-evaluate their approach. The mission's success relies on their ability to adapt to these unexpected challenges and find a way to safely land on the rapidly spinning, diminutive asteroid.
