🪨 New study quantifies controls on iron redox in Martian magmas using Mössbauer, wet chemistry & XANES analyses. Results show strong temperature sensitivity of Fe³⁺/Feᵀ. 👉 doi.org/10.1029/2025JE009148 #Mars #PlanetaryScience #AGU26 #AGUPSS26

🔴 New study suggests Al-rich clays in Nili Fossae formed through alteration of reworked Al/Si-rich volcaniclastic sediments, rather than prolonged basalt weathering—implying more limited aqueous activity on ancient Mars. 👉 agupubs.onlinelibrary.wiley.… #Mars #AGU26 #AGUPSS26

🔴 New study using MAVEN observations finds that currents in Mars’ dayside ionosphere are primarily solar-wind driven, with a smaller role from neutral-wind dynamo processes. Read more at👉 agupubs.onlinelibrary.wiley.… #Mars #MAVEN #PlanetaryScience #AGU26 #AGUPSS26

🚀 Mare Vaporum may be a prime target for future lunar exploration. New geologic mapping identifies resource-rich pyroclastic deposits, prolonged tectonic activity, and favorable landing conditions for future missions. 👉 iopscience.iop.org/article/1… #Moon #ISRU #AGU25 #AGUPSS25

🏜️ Curiosity reveals Gale crater’s sulfate unit formed in a complex environment of wind-driven sands + fluctuating groundwater, not simple long-term drying. 👉 agupubs.onlinelibrary.wiley.… #Mars #Curiosity #PlanetaryScience #AGU25 #AGUPSS25

🌕 New study uses Mini-RF radar to map lunar mass wasting—landslides, debris flows & rockfalls. Distinct radar signatures can help identify hazards, even in poorly lit or shadowed regions. Read the paper here👉 doi.org/10.1029/2025JE009484 #Moon #PlanetaryScience #AGU25 #AGUPSS25

🌕 Apollo seismic + GRAIL gravity data refine the Moon’s interior: Average crustal thickness = 43.6 ± 1.9 km, with strong regional variations. Read more at👉 doi.org/10.1029/2025JE009453 #Moon #PlanetaryScience #AGU25 #AGUPSS25

🌌 Nearly 10 years of MAVEN data show Mars’ upper atmosphere is shaped by a complex mix of solar EUV, dust storms, and global circulation. Read more at👉 doi.org/10.1029/2025JE009510 #Mars #MAVEN #PlanetaryScience #AGU25 #AGUPSS25

☁️ Venus hosts the largest hydraulic jump in the Solar System. A 6,000-km cloud front forms as atmospheric waves trigger sulfuric acid condensation—helping drive superrotation. Read more at👉 agupubs.onlinelibrary.wiley.… #Venus #PlanetaryScience #AGU25 #AGUPSS25

🌊 Martian deltas may not require long warm climates. Study shows formation via multiple water sources and episodic activity over long timescales. Read more at👉 iopscience.iop.org/article/1… #Mars #PlanetaryScience #AGU25 #AGUPSS25

❄️ How long do lunar cold traps last? Large craters can host PSRs for billions of years—but small ones may last only ~10–100 Myr. Read the new study at👉 iopscience.iop.org/article/1… #Moon #PlanetaryScience #AGU25 #AGUPSS25

🌌 Can Dragonfly detect Titanquakes? Study shows low-frequency seismic signals may be detectable—offering clues to ice shell thickness. 👉 agupubs.onlinelibrary.wiley.… #Titan #Dragonfly #PlanetaryScience #AGU25 #AGUPSS25

⚡ New study revisits Saturn lightning (SEDs) from Voyager data. Finds polarization depends on geometry and shows ionospheric effects can mimic equatorial sources. 👉 agupubs.onlinelibrary.wiley.… #Saturn #PlanetaryScience #AGU25 #AGUPSS25

🌋 How well do sediments preserve their origin? Mars-analog study shows transport & sorting can mask source signals, with altered materials often lost. Read the new study by Putnam et al., 2026 here👉 agupubs.onlinelibrary.wiley.… #Mars #PlanetaryScience #AGU25 #AGUPSS25

🛰️ Mars-like sublimation can enhance biosignature detection initially, but prolonged exposure reduces some signals. Important implications for the Rosalind Franklin rover. Read more at👉 agupubs.onlinelibrary.wiley.… #Mars #Astrobiology #PlanetaryScience #AGU25 #AGUPSS
