TL;DR
Japan’s Hayabusa2 spacecraft will conduct a flyby of the Torifune asteroid, aiming to collect data on its composition and orbit. This event advances Japan’s asteroid exploration efforts and provides insights into small celestial bodies.
Japan’s Hayabusa2 spacecraft is set to perform a flyby of the Torifune asteroid in late 2023, according to the Japan Aerospace Exploration Agency (JAXA). This event represents a key milestone in the spacecraft’s extended mission to study small celestial bodies and gather data that could inform future planetary defense and exploration efforts.
The flyby is scheduled for late 2023, with precise timing depending on orbital calculations. JAXA officials confirmed that Hayabusa2 will pass within a close distance of the Torifune asteroid, a small near-Earth object (NEO) measuring approximately 150 meters across. The spacecraft’s instruments will collect data on the asteroid’s surface composition, shape, and orbit, continuing the mission’s goal of understanding the properties of small bodies in the solar system.
Hayabusa2 previously collected samples from the asteroid Ryugu and has been orbiting and studying other objects since its primary mission concluded. The upcoming flyby of Torifune is part of a broader effort to expand knowledge about NEOs, which could pose impact threats or serve as resource sites in the future. The spacecraft’s onboard instruments include cameras, spectrometers, and a laser altimeter, which will be used during the flyby to gather detailed observations.
Implications for Planetary Defense and Space Science
This flyby offers valuable insights into the physical and chemical properties of small asteroids, which are crucial for developing planetary defense strategies. Understanding the composition and structure of NEOs like Torifune can inform impact risk assessments and potential mitigation techniques. Additionally, the data contribute to scientific knowledge about the early solar system, as small bodies are remnants of planetary formation processes.
Furthermore, Japan’s successful execution of this flyby demonstrates the capabilities of its space exploration program, positioning JAXA as a significant player in asteroid research. The mission also supports international efforts to monitor and understand near-Earth objects, which could become threats or resource sources in the future.

Previous Missions and the Role of Hayabusa2 in Asteroid Research
Japan’s Hayabusa2 mission, launched in 2014, successfully collected samples from the asteroid Ryugu in 2019 and returned them to Earth in 2020. This achievement marked a major milestone in asteroid exploration, providing scientists with direct samples for analysis. Since then, Hayabusa2 has been involved in orbiting and studying other small bodies, including the upcoming Torifune flyby.
Torifune, a relatively small NEO, has garnered interest due to its proximity and potential as a target for future exploration or resource utilization. The upcoming flyby builds on previous missions, leveraging Hayabusa2’s advanced instruments to gather detailed data remotely. Japan’s focus on small-body exploration aligns with global efforts to understand the diversity and behavior of near-Earth objects.
“The upcoming flyby of Torifune will provide critical data on its surface and orbit, enhancing our understanding of small near-Earth objects.”

Details on Exact Timing and Data Collection Scope
While the scheduled timing for the flyby is confirmed for late 2023, precise details such as the exact date, distance of closest approach, and specific data collection plans are still being finalized. It is also unclear how much new data will be obtained compared to previous observations of similar objects.
Further updates from JAXA are expected as the mission approaches, but some aspects remain under development or subject to orbital adjustments.
Next Steps After the Torifune Flyby
Following the flyby, JAXA plans to analyze the collected data and publish detailed scientific reports. The agency may also consider future missions targeting similar NEOs for sample return or in-depth exploration. Additionally, the data from this flyby could inform planetary defense strategies and future asteroid resource assessments.
Preparations are underway for post-flyby operations, including data transmission and analysis, with further updates anticipated in the coming months.
