@sahar_shahaf and I looked at Europa, as observed by @JNASAWebb from several viewing angles. We then used spectral decomposition to identify surface processes and found several CO2-enriched terrains! First paper accepted to ApJ, and is now live on @arxiv: arxiv.org/html/2603.1052…

למה מאדים אדום? 🤔🔴 מחקר חדש חושף גילוי פורץ דרך שמקרב אותנו להבנת ההיסטוריה של מאדים! הצבע האדמדם של מאדים, טוענים החוקרים, לא נובע מהמינרל שחשבנו עד היום, אלא מחומר אחר – שמהווה עדות לכך שכוכב הלכת היה במים שאפשרו התפתחות חיים. כל הפרטים בכתבה >> space.gov.il/news-space/134…

The Effect of Ground Ice Redistribution on the Martian Paleo-CO2 Cycle. buff.ly/3E5UMzB Ground water ice migration with the evolving orbit reduces the seasonal CO2 duration and mass in mid-latitudes at high obliquity periods.

My first paper with @odedaha @Eranium_V @norbertinhawaii recently got published on JGR-Planets! it uses climate and ground ice models to simulate the effect of ground ice migration on the CO2 cycle in past climates. Check it out here agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

The 8th International Mars Polar Conference has been an incredible experience - thank you @Mars_Polar ! I presented my ongoing work with @odedaha and @phayne on the BRDF of CO2

I encountered a delightful little astrodynamics proof last week when an astronaut casually stated it as a fact, and when I looked skeptical, he just smiled and said, "Check it yourself." Here's the statement: "It takes 2 hours to orbit at the surface of any object made of rock"

A new image released from the Large Binocular Telescope showing Jupiter's moon Io. The sharpest ever taken from a ground based telescope and well beyond what even HST has produced. From Earth Io spans around 1 arc second across. news.berkeley.edu/2024/05/30/wit…

@norbertinhawaii @AAS_Publishing @planetarysci @NASAGoddard @UCLA Congrats Norbert!

Our new paper about north polar cold traps on the Moon is out. We even found cold traps that aren't cold traps. "Lunar North Polar Cold Traps Based on Diurnally and Seasonally Varying Temperatures" doi.org/10.3847/PSJ/ad… via @AAS_Publishing @planetarysci @NASAGoddard @UCLA

@AliBramson Congratulations!

I'm super honored that our amazing and hard-working International Mars Ice Mapper Measurement Definition Team has received a Group Achievement Award from NASA Headquarters!

Io from yesterday’s Juno flyby - incredible!

New paper about Mars subsurface ice and how it affects the NPLD stratigraphy is finally out!! agupubs.onlinelibrary.wiley.com/doi/10.1029/20… @norbertinhawaii @PlanetsAtWIS @jgrplanets

Red soil + snow on the Ausangate trek in Peru giving strong wintertime Mars vibes…

buff.ly/3LukUVD @EarthSky Scientists at PSI and @SwRI announced a new study that suggests water ice is both younger and less extensive on the Moon than scientists previously thought. This could have implications for future human habitation on the moon...

Also had the pleasure of taking part in the Justitia’s occultation observation campaign, led by Marc Buei of @SwRI in preparation for the upcoming Emirates Mission to the Asteroids @uaespaceagency - a very unique experience

Just finished 2 months at @LASPatCU with @phayne and the EPIC group - an incredible way to start my PhD! Looking forward to continuing our work together

Chandrayaan-3 Mission: On August 27, 2023, the Rover came across a 4-meter diameter crater positioned 3 meters ahead of its location. The Rover was commanded to retrace the path. It's now safely heading on a new path. #Chandrayaan_3 #Ch3

During northern hemisphere winter on Mars, several meters of water and carbon-dioxide frost and ice are deposited in the polar region.
