# New framework predicts asteroid impact sites from orbital data alone

A team of researchers has developed a method to forecast meteorite strewn fields using only pre-impact orbital solutions, a capability tested against asteroid Bennu.

Anna Moscati and colleagues present an ab initio framework that predicts meteorite strewn fields of near-Earth asteroids directly from pre-impact orbital solutions without requiring fireball triangulation or event-specific tuning [^1].

Validation against recent asteroid falls with recovered meteorites shows agreement, with nominal solutions reproducing fall locations within 100-200 meters [^2].

When applied to asteroid Bennu using cohesive forces measured from samples returned by NASA's OSIRIS-REx mission in 2023, the framework predicted Bennu's surface strength to be below 1 pascal [^3].

Sánchez noted the framework could provide initial approximations to asteroid tensile and cohesive strengths, which are basic material parameters for impact simulation codes used in the only tested method for asteroid deflection, as demonstrated by NASA's DART mission striking Dimorphos in 2022 [^4].
