Mission Design and Early Navigation Operations for the Lunar Trailblazer Mission

Earth 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 ...

Impact of Magnetosphere Forcing and Model Resolution on Joule Heating Estimates in WACCM‐X During the 24 August 2005 Storm

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Ionospheric Response to the Extreme Geomagnetic Storm of 10–11 May 2024 Based on Total Electron Content Observations in the Central Asian and East Asian Regions

Atmosphere
The ionospheric response to the major geomagnetic storm (SYM-H = −518 nT) of 10–11 May 2024 was investigated using total electron content (TEC) observations from the Central Asian (CAR) and East Asian (EAR) regions.

Interplanetary Tracking of the 23 March 2024 CME: Computer Tomographic Analyses of IPS, White‐Light, and Type II Radio Burst Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract We analyze the propagation of a coronal mass ejection (CME) observed on 23 March 2024, at 01:25 UT by SOHO/LASCO using a multi‐instrument and multi‐method approach. The study combines Interplanetary Scintillation (IPS), type II radio bursts, white‐light, in‐situ observations, and 3D tomographic reconstruction of the inner heliospheric density.

Seismogenic Effects in Variation of the ULF/VLF Emission in a Complex Study of the Lithosphere–Ionosphere Coupling Before an M6.1 Earthquake in the Region of Northern Tien Shan

Geosciences
A complex study was performed of the disturbances in geophysics parameters that were observed during a short-term period of earthquake preparation. On 4 March 2024, an M6.1 earthquake (N 42.93, E 76.966) occurred with the epicenter 12.2 km apart from the

Undifferenced Integer Ambiguity Resolution in GNSS Network Solutions: Benefits to Satellite Orbits, ERP, Geocenter, and Station Coordinates

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Integer ambiguity resolution (IAR) is critical in high‐precision Global Navigation Satellite Systems (GNSS) data processing. While the legacy double‐differenced (DD) IAR is widely adopted by most analysis centers (ACs) of the International GNSS Service, undifferenced (UD) IAR is gaining popularity for global network solutions.

High‐Rate GNSS Analysis of the Onset, Growth, and Termination of Slow Slip Events and Their Along‐Dip Variability Offshore the Boso Peninsula, Japan (2011–2024)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Recurring slow slip events (SSEs) with moment magnitudes in the mid‐6 range have occurred every few years since the 1990s offshore the Boso Peninsula, Japan. These events occur near the source area of ∼M8 megathrust earthquakes beneath the Tokyo metropolitan area and are accompanied by earthquake swarms.

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.
