TL;DR
Japan’s Hayabusa2 spacecraft will conduct a flyby of the Torifune asteroid, aiming to gather valuable data. This event advances Japan’s asteroid exploration efforts and could provide insights into asteroid composition.
Japan’s Hayabusa2 spacecraft is set to conduct a flyby of the Torifune asteroid in late April 2024, according to the Japan Aerospace Exploration Agency (JAXA). This event marks a key milestone in the mission’s ongoing efforts to study near-Earth objects and gather data that could inform future planetary defense and exploration initiatives.
The flyby is scheduled for late April 2024, with the spacecraft approaching the small asteroid Torifune, located in the vicinity of Earth. JAXA officials confirmed that the probe will pass within approximately 20 kilometers of the asteroid’s surface, collecting high-resolution images and spectroscopic data.
Hayabusa2, which previously visited the asteroid Ryugu and returned samples to Earth in 2020, is now focusing on Torifune as part of its extended mission. The spacecraft’s instruments will analyze the asteroid’s surface composition, shape, and rotation, providing insights into the early solar system and the origins of asteroids.
JAXA has emphasized that this flyby is a scientific observation mission, with no plans for sample collection during this event. The data collected will complement previous findings and contribute to ongoing research on asteroid diversity and evolution.
Implications for Asteroid Research and Planetary Defense
This flyby represents a significant step in asteroid exploration, offering an opportunity to study a different type of asteroid than Ryugu. The data could improve models of asteroid composition and behavior, which are critical for planetary defense strategies. Additionally, understanding the diversity among near-Earth objects can inform future missions aimed at resource utilization or deflection techniques.

Hayabusa2’s Extended Mission and Past Achievements
Launched in December 2014, Hayabusa2 successfully reached the asteroid Ryugu in 2018, where it collected samples and performed detailed surface analysis before returning to Earth in 2020. The mission has been praised for its technological achievements and contributions to planetary science.
After the Ryugu mission, JAXA extended Hayabusa2’s mission to include flybys of additional near-Earth objects, including the upcoming encounter with Torifune. This reflects Japan’s ongoing commitment to asteroid research and planetary defense.
Torifune, a small asteroid approximately 1 kilometer in diameter, was identified as a target for the upcoming flyby due to its orbit and composition, which could provide new scientific insights.
“The upcoming flyby of Torifune will provide valuable data on asteroid surface properties and contribute to our understanding of near-Earth objects.”

Details of the Flyby and Data Collection Methods Still Unclear
While the timing and proximity of the flyby are confirmed, specific details about the instrument settings and data collection plans remain undisclosed. It is also unclear whether the spacecraft will perform any maneuvers during the flyby or if additional observations are planned afterward. The exact scientific objectives for this event are still being finalized by JAXA.
Data Analysis and Future Missions Post-Flyby
Following the flyby, JAXA will analyze the collected data over the coming months, with preliminary results expected by mid-2024. The agency may also consider future missions based on the findings, potentially including sample-return efforts from other small bodies or targeted asteroid deflections.
The success of this flyby could influence the planning of subsequent asteroid exploration missions and enhance international collaboration on planetary defense initiatives.
