And what's best than being able to "actually" visit these sites? So we embedded the models in #VirtualReality 😎 5/X

Interesting! Especially knowing some people largely abusing on the price of their replicas, so waiting to see. But that will never beat BlueBrixx's version

Browsing accros the "Mars" algorithm of BSky, I recommend you doing it! But I'm really upset, how could a complotist account with endless bullshit like that have much more followers than people actually studying Mars for a living? (More than me clearly 😅) Don't let BSky become the worse of X...

Based on these data, we highlight 4 hydrogeological cycles, indicating that the lake-level in Jezero fluctuate during and in-between episodes of deltaic construction, with variations up to 10 meters at the time of Kodiak being deposited

Dr. Gwénaël Caravaca 🔴 ⛏ @gccmars.eurosky.social · 10/04/2024

In turn, these facies also allow us to highlight 3 different units, associated with 3 individual mouth bars : unique discrete piece of deltaic construction

J'ai essayé de regarder en fait 😜 Théoriquement, vu la résolution de l'HiRISE de 25 cm/pixel au mieux, non. Après si l'ombre portée était assez grande... Ou en faisant de la superrésolution faudrait une bonne demie-douzaine d'images... Sachant que la cam est petite (photo réplique Cité de l'Espace)
