Hayabusa2’s daring 800-meter flyby reveals Torifune as a contact-binary asteroid

Japan’s JAXA Hayabusa2 mission carried out an exceptionally close flyby of near-Earth asteroid Torifune, reaching about 800 meters from the asteroid’s center at a speed of roughly 5.3 km/s after months of debate over safety. The flyby produced high-resolution imagery showing Torifune is a contact-binary asteroid larger than anticipated, with all four science instruments returning data and the most urgent data downlinked, while the full 300 MB dataset will arrive later. The mission demonstrates rapid asteroid characterization capabilities and could inform future planetary-defense efforts, including potential impactor-style investigations.

Hayabusa2's 800-meter close shave reveals Torifune as a binary asteroid

Hayabusa2 pushed its aging craft to a record-close 800-meter flyby of the near‑Earth asteroid Torifune, a binary rock, after a heated debate over risk; the mission returned close images and science data from all four instruments, including nine seconds of Thermal Infrared Imaging and a possible first LIDAR ranging during an asteroid flyby, with about 25 MB of data downlinked initially and some 300 MB total expected. The operation demonstrated fast reconnaissance capabilities for planetary defense and paves the way for the spacecraft's 2031 rendezvous with KY26.

Hayabusa2 photographs Torifune on a distant, high‑speed flyby

Japan’s Hayabusa2 spacecraft conducted a high‑speed flyby of asteroid Torifune about 62 million miles from Earth, capturing optical imagery with its ONC‑T camera and thermal data with the Mid‑Infrared Camera to analyze surface temperatures and roughness. The encounter, not part of the original mission and described as risky, adds to Hayabusa2’s long-running exploration after returning Ryugu’s samples in 2020 and sets the stage for its future target 1998 KY26 in 2031 while showcasing the probe’s ongoing study of small solar‑system bodies.

Hayabusa2 completes Torifune asteroid flyby, on track to 2031 target

Japan's Hayabusa2 completed a high-speed flyby of the Torifune asteroid as part of its Extended Mission, with data confirming success and potential image release; the probe continues toward its final target in 2031 and aims to advance close-approach technology for planetary defense.

Hayabusa2 to skim Torifune from a room-temperature: ultra-close asteroid flyby on tap

Japan’s Hayabusa2, on an extended mission after Ryugu, will perform one of the closest asteroid flybys by a mission of its class, approaching Torifune to within about 1 kilometer at ~5.3 km/s on July 5 to study its shape and properties and test rapid reconnaissance for planetary defense—with a long-term aim to visit the tiny asteroid 1998 KY26 in 2031, potentially landing there.
