Coherent interdecadal cycles in global rainfall, temperature, and cloud cover with alignment to Jovian orbital periods

Environmental Research Letters
Interdecadal cycles repeatedly appear in global climate variables such as rainfall, temperature, and the climate modes, yet their origin remains unresolved and is most often attributed either to quasi-periodic artefacts of internal climate variability ...

MAVEN Observations of Metallic Fe+ Distributions in the Martian Ionosphere

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Metallic ions deposited in planetary atmospheres via meteoroid ablation are an invaluable tool for understanding electric fields, atmospheric winds, and minor ion transport. At Mars, metallic ion distributions are poorly understood. We analyze MAVEN/NGIMS Fe+ ${\mathrm{F}\mathrm{e}}^{+}$ distributions in the Martian ionosphere over the period ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Oued Chebeika 002: A new CI1 meteorite linked to outer solar system bodies

Meteoritics &Planetary Science, Volume 60, Issue 7, Page 1441-1479, July 2025.
Abstract CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ryugu and Bennu asteroids returned by the JAXA Hayabusa2 and NASA's OSIRIS‐REx missions.

The COBE Diffuse Infrared Background Experiment Search for the Cosmic Infrared Background: I. Limits and Detections [PDF]

, 1998
The DIRBE on the COBE spacecraft was designed primarily to conduct systematic search for an isotropic CIB in ten photometric bands from 1.25 to 240 microns. The results of that search are presented here.

Do the Antennas of DEMETER Spacecraft Detect Dust Impacts?

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract This study investigates pulses detected by the electric field instrument, ICE (Instrument Champ Electrique) onboard the DEMETER spacecraft. Using an automated identification algorithm, we identified 1,000 short pulses recorded in 2005 and 2010. The spatial distribution of these signals, primarily localized over South America and near the South

Heliospheric modulation of the interstellar dust flow on to Earth

, 2018
Aims. Based on measurements by the Ulysses spacecraft and high-resolution modelling of the motion of interstellar dust (ISD) through the heliosphere we predict the ISD flow in the inner planetary system and on to the Earth.

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1227-1235, May 2025.
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...
