RESONANCES IN ASTEROID SYSTEMS

open access: yesOdessa Astronomical Publications, 2016
Today the following types of resonances in the rotation of celestial bodies in the solar system are known, namely orbital, spin-orbit and spin-spin resonances.

Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Lunar Trailblazer is a smallsat mission launched on 27 February 2025 as a secondary payload with the Intuitive Machines IM‐2 mission. After insertion into a near‐polar circular orbit around the Moon, the mission's goal was to search and characterize lunar water, primarily looking for ice in permanently shadowed craters and water bound in ...

Lightcurves, Rotation Periods, and Colors for Vera C. Rubin Observatory’s First Asteroid Discoveries

open access: yesThe Astrophysical Journal Letters
We present lightcurves, rotation periods, and colors for the first asteroid discoveries made with the NSF-DOE Vera C. Rubin Observatory. These are the first science results derived from the 2103 asteroid discoveries released as part of the Rubin First ...

Exploring rotational properties and the YORP effect in asteroid families

open access: yesAstronomy & Astrophysics
Context. The long-term dynamical evolution of asteroid families is governed by the interplay between orbital and rotational evolution driven by thermal forces and collision. Aims.

Asteroid spin-rate studies using large sky-field surveys

open access: yesGeoscience Letters, 2017
Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from which we identified two new super-fast rotators (SFRs ...

Preatmospheric Detection of a Meter-sized Earth Impactor

open access: yesThe Planetary Science Journal, 2023
On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound ...

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

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.

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...
