TL;DR
Japan’s Hayabusa2 spacecraft is scheduled to conduct a flyby of the Torifune asteroid. This event is part of ongoing efforts to study near-Earth objects and gather valuable data for planetary defense and science.
Japan’s Hayabusa2 spacecraft is set to perform a flyby of the Torifune asteroid in late 2024, marking a new phase in its mission to study near-Earth objects. This operation aims to gather detailed data on the asteroid’s composition and trajectory, which is crucial for planetary defense and scientific research.
The Japan Aerospace Exploration Agency (JAXA) announced that Hayabusa2 will approach the Torifune asteroid during a carefully planned flyby in late 2024. The spacecraft, which originally landed on asteroid Ryugu in 2019, has been in space since its launch in 2014 and has completed its primary mission of sample collection. The upcoming flyby is part of an extended mission to observe and analyze additional near-Earth objects.
According to JAXA officials, the flyby will allow Hayabusa2 to collect high-resolution images and spectroscopic data, providing insights into the asteroid’s surface features and composition. The spacecraft’s onboard instruments have been calibrated for this purpose, and the operation is scheduled to occur at a safe distance to avoid any collision risk. The agency emphasized that the data collected could improve models of asteroid trajectories and inform future planetary defense strategies.
Implications for Planetary Defense and Science
This flyby represents a critical step in planetary defense efforts, as understanding the physical characteristics and trajectories of near-Earth objects like Torifune can help predict and mitigate potential impact threats. Additionally, the data will contribute to scientific knowledge about asteroid composition and the early solar system. The mission also demonstrates Japan’s continued leadership in space exploration and asteroid research, following the success of Hayabusa2’s sample return from Ryugu.

Hayabusa2’s Mission and Near-Earth Object Research
Launched in 2014, Hayabusa2 has been orbiting space for nearly a decade, initially targeting the asteroid Ryugu, which it sampled and returned to Earth in 2020. Since then, the spacecraft has been repurposed for extended missions to observe other near-Earth objects, including the upcoming Torifune flyby. The mission aligns with global efforts to catalog and study potentially hazardous asteroids, aiming to develop better detection and deflection techniques.
Previous asteroid missions, including NASA’s OSIRIS-REx, have provided valuable data, but Hayabusa2’s upcoming flyby offers a unique opportunity to observe Torifune in detail without the need for landing or sample collection. The mission also builds on Japan’s long-standing expertise in small-body exploration, which began with the original Hayabusa mission in 2003.
“The upcoming flyby of Torifune will provide unprecedented data on its surface and trajectory, enhancing our understanding of near-Earth objects.”

Upcoming Preparations and Expected Data Releases
JAXA is currently finalizing the spacecraft’s trajectory and instrument calibration for the Torifune flyby, scheduled for late 2024. After the event, scientists expect to analyze the collected data over several months, which could lead to published findings on the asteroid’s surface composition and orbit. The agency also plans to share initial observations with the scientific community and the public shortly after the flyby.
