The uncertainty region for #Hayabusa2 approaching #Torifune was about 300 m long. That combined with the asteroid's maximum radius to set the minimum safe flyby distance of 800 m. #ACM2026

The last session of #ACM2026 starts with Makoto Yoshikawa presenting the preliminary results of the #Hayabusa2 flyby of #Torifune on behalf of the mission team, who are still quite busy.

Paul Simon presents a combination of dynamical, space weathering, and spectral models to try and figure out just where near-Earth asteroids visited by spacecraft came from.

Suggests Eros, #Itokawa, #Torifune, and #Apophis all came from the main-belt asteroid Flora 1.2 billion years ago.

Patrick Michel updates #ACM2026 on the #HeraMission.

Quotes the surface ages for Didymos and Dimorphos as 12.5 million years and <300,000 years respectively.

That was before the #DARTMission impact.
