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.

Influence of Solar Sails on Magnetic Field Measurements in Space Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Solar sail technology is ready to be deployed in a satellite mission carrying a science‐grade magnetometer. In preparation for such a mission, it is essential to characterize the interactions between the sail and the ambient plasma that could affect the magnetometer readings.

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

Spectral evidence of size dependent space weathering processes on asteroid surfaces

, 1993
Most compositional characterizations of the minor planets are derived from analysis of visible and near-infrared reflectance spectra. However, such spectra are derived from light which has only interacted with a very thin surface layer. Although regolith

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.

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

Characterization of asteroid analogues by means of emission and reflectance spectroscopy in the 1-to 100-mu m spectral range

, 2016
The last decades have seen a large number of missions targeting small bodies in the solar system. NASA, ESA and JAXA sent missions to different solar system small bodies (SSSB), and the Japan mission Hayabusa returned samples from the surface of the S ...

Kineochelins—A New Group of Siderophores From an Antarctic Bacterium

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...
