TL;DR
Japan’s Hayabusa2 spacecraft is scheduled to perform a flyby of the Torifune asteroid. This event advances Japan’s asteroid research efforts and provides new scientific data. The flyby is planned for the coming weeks.
Japan’s Hayabusa2 spacecraft is set to perform a flyby of the Torifune asteroid in late March 2024, marking a key milestone in its ongoing mission to study near-Earth objects and gather valuable scientific data. This maneuver is confirmed by the Japan Aerospace Exploration Agency (JAXA), which manages the mission, and underscores Japan’s commitment to advancing asteroid research.
The Hayabusa2 spacecraft, launched by JAXA in December 2014, has previously studied the asteroid Ryugu and returned samples to Earth in 2020. Its upcoming flyby of Torifune, a small near-Earth asteroid, is part of a broader scientific objective to analyze asteroid composition, surface features, and orbital characteristics. JAXA officials confirmed that the flyby will occur around late March 2024, with the spacecraft approaching within a few kilometers of the asteroid’s surface.
During the flyby, Hayabusa2 will use its onboard instruments, including cameras and spectrometers, to capture high-resolution images and collect data on Torifune’s physical and chemical properties. The mission team aims to compare these findings with previous asteroid data, contributing to understanding the diversity of near-Earth objects and their potential impact threat.
Why the Torifune Flyby Is Scientifically Important
This flyby is significant because it provides an opportunity to study a different type of asteroid than Ryugu, offering insights into the diversity of near-Earth objects. The data collected could improve models of asteroid composition and behavior, which are vital for planetary defense and future asteroid mining efforts. Additionally, the mission enhances Japan’s leadership in space exploration and asteroid science, fostering international collaboration.

Background on Hayabusa2 and Its Mission Milestones
Launched in December 2014, Hayabusa2 has previously conducted a successful mission to asteroid Ryugu, where it collected samples and returned them to Earth in 2020. The spacecraft has since been in orbit around Ryugu, conducting further observations, and now, it is transitioning to its next phase—studying new targets like Torifune. This upcoming flyby follows a series of successful maneuvers that demonstrate the spacecraft’s extended operational capability.
Torifune, a small near-Earth asteroid, was identified as a target for this flyby based on its orbit and physical characteristics. The mission’s goal is to gather comparative data to better understand the variety among near-Earth objects, which has implications for planetary defense and resource utilization.
“We expect to approach within a few kilometers of Torifune and capture detailed images and data during the maneuver. The mission team is preparing for precise navigation and data collection.”
