Anticipating the DART impact: Orbit estimation of Dimorphos using a simplified model
Shantanu P. Naidu, Steven R. Chesley, Davide Farnocchia +5
We used the times of occultations and eclipses between the components of the 65803 Didymos binary system observed in its lightcurves from 2003-2021 to estimate the orbital paramete…
Isolating the mechanisms for asteroid surface refreshing
F. E. DeMeo, M. Marsset, D. Polishook +10
Evidence is seen for young, fresh surfaces among Near-Earth and Main-Belt asteroids even though space-weathering timescales are shorter than the age of the surfaces. A number of me…
After DART: Using the first full-scale test of a kinetic impactor to inform a future planetary defense mission
Thomas S. Statler, Sabina D. Raducan, Olivier S. Barnouin +38
NASA's Double Asteroid Redirection Test (DART) is the first full-scale test of an asteroid deflection technology. Results from the hypervelocity kinetic impact and Earth-based obse…
The Nature of Low-Albedo Small Bodies from 3-m Spectroscopy: One Group that Formed Within the Ammonia Snow Line and One that Formed Beyond It
Andrew S. Rivkin, Joshua P. Emery, Ellen S. Howell +9
We present evidence, via a large survey of 191 new spectra along with previously-published spectra, of a divide in the 3-m spectral properties of the low-albedo asteroid populat…
Connecting Asteroids and Meteorites with visible and near-infrared spectroscopy
Francesca E. DeMeo, Brian J. Burt, Michaël Marsset +12
We identify spectral similarities between asteroids and meteorites. We identify spectral matches between 500 asteroid spectra and over 1,000 samples of RELAB meteorite spectra over…
The debiased compositional distribution of MITHNEOS: Global match between the near-Earth and main-belt asteroid populations and excess of D-type Near-Earth Objects
Michaël Marsset, Francesca E. DeMeo, Brian Burt +10
We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects (NEOs) collected on the NASA InfraRed Telescope Facility (IRTF) as part of the MIT-Hawaii NEO S…
