A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Payload Selection Scheme for a Fast‐Response Planetary Defense Scouting Mission: The Satis CubeSat Study

Advances in Astronomy, Volume 2026, Issue 1, 2026.
The continued detection of near‐Earth asteroids with postulated close encounters with Earth is a clear motivation for planetary defense–driven mission designs. Fast reconnaissance in an imminent threat scenario (i.e., less than a few years upon impact) is crucial to gain information about an asteroid potentially impacting the Earth in the near future ...

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO). III. Dust and Gas Disk Properties in the Lupus Star-forming Region

The Astrophysical Journal
We present Band 6 and Band 7 observations of 10 Lupus disks around M3-K6 stars from the Atacama Large Millimeter/submillimeter Array survey of Gas Evolution in PROtoplanetary disks (AGE-PRO) Large Program. In addition to continuum emission in both bands,

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Mineralogically Diverse and Salt‐Rich Regolith in Jezero Crater Characterized Using X‐Ray Spectroscopy

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...

exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks

The Astrophysical Journal Letters
Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes and the presence of protoplanets within disks.

Antum Crater: A Window Into Ganymede's Icy Evolution

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Located within the extensive dark terrain of Marius Regio, in the anti‐Jovian trailing quadrant of Ganymede, Antum crater is marked by dark‐rayed ejecta that obscure older features and reshape the surrounding landscape. This study investigates Antum and its geological context using optical and infrared data from the Voyager and Galileo ...
