A Photometric Survey of over 200 V-type Asteroids and Their Phase-curve Analysis

open access: yesThe Astrophysical Journal Supplement Series
V-type asteroids are considered to be crustal fragments of asteroid (4) Vesta and possibly of other differentiated parent bodies that once existed in the main asteroid belt.

Optical Monitoring of the Didymos–Dimorphos Asteroid System with the Danish Telescope around the DART Mission Impact

open access: yesThe Planetary Science Journal, 2023
The NASA’s Double-Asteroid Redirection Test (DART) was a unique planetary defence and technology test mission, the first of its kind. The main spacecraft of the DART mission impacted the target asteroid Dimorphos, a small moon orbiting the asteroid ...

Photometry of Outer Solar System Objects from the Dark Energy Survey. I. Photometric Methods, Light-curve Distributions, and Trans-Neptunian Binaries

open access: yesThe Astrophysical Journal Supplement Series, 2023
We report the methods of and initial scientific inferences from the extraction of precision photometric information for the >800 trans-Neptunian objects (TNOs) discovered in the images of the Dark Energy Survey (DES). Scene-modeling photometry is used to

The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

The Secular Dynamical Evolution of Binary Asteroid System (65803) Didymos Post-DART

open access: yesThe Planetary Science Journal
The successful impact of NASA’s DART mission with Dimorphos, the secondary body of binary asteroid system (65803) Didymos, altered the attitude, shape, and orbit of Dimorphos.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

The Cumulation of Debris Clouds around a Fast-rotating Asteroid

open access: yesThe Astrophysical Journal
The rotational mass loss has been realized to be a prevalent mechanism to produce low-speed debris near the asteroid, and the size composition of the asteroid’s surface regolith has been closely measured by in situ explorations.

Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

Probing Subsurface Properties With Mission Hardware: Lessons Learned From Artificial Impacts of Mars 2020

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hardware released during spacecraft entry can generate hypervelocity impacts that provide unique constraints on planetary subsurface properties. During NASA's Perseverance descent, two tungsten cruise ballast mass devices (CBMD) and fragments of the cruise stage formed meter‐scale craters north‐west of Jezero crater, in one of the sinuous ...
