Pre-impact Thermophysical Properties and the Yarkovsky Effect of NASA DART Target (65803) Didymos

The Planetary Science Journal
The NASA Double Asteroid Redirection Test (DART) spacecraft impacted the secondary body of the binary asteroid (65803) Didymos on 2022 September 26 and altered its orbit about the primary body.

Spectral and Spin Measurement of Two Small and Fast-Rotating Near-Earth Asteroids

, 2012
In May 2012 two asteroids made near-miss "grazing" passes at distances of a few Earth-radii: 2012 KP24 passed at nine Earth-radii and 2012 KT42 at only three Earth-radii. The latter passed inside the orbital distance of geosynchronous satellites.

Measuring the Sizes, Shapes, Surface Features and Rotations of Solar System Objects with Interferometry

, 2011
We consider the application of interferometry to measuring the sizes and shapes of small bodies in the solar system that cannot be spatially resolved by today's single-dish telescopes.

Mid-infrared Measurements of Ion-irradiated Carbonaceous Meteorites: How to Better Detect Space Weathering Effects

The Planetary Science Journal
Remote sensing study of asteroids will soon enter a new era with an increasing amount of data available thanks to the JWST, especially in the mid-infrared (MIR) range that allows identification of mineral species.

Detection of a 2.85 μm Feature on Five Spinel-rich Asteroids from JWST

The Astrophysical Journal Letters
Ground-based observations of “Barbarian” L-type asteroids at 1–2.5 μ m indicate that their near-infrared spectra are dominated by the mineral spinel, which has been attributed to a high abundance of calcium-aluminum inclusions (CAIs)—the first solids to ...

A Comparative Study of Infrared Asteroid Surveys: IRAS, AKARI, and WISE

, 2014
We present a comparative study of three infrared asteroid surveys based on the size and albedo data from the Infrared Astronomical Satellite (IRAS), the Japanese infrared satellite AKARI, and the Wide-field Infrared Survey Explorer (WISE).
