Martian Vistas

Check out this epic Stereo3D vision captured by Perseverance, where the stereoscopic effect is strongly enhanced by the foreground boulder field.

Finding "hidden" topographic features with advanced mapping techniques! Clear and concise connections to all Jezero science, loved this paper.

Perseverance has moved forward to close-in with the big frowning boulder...

🌊 Water Enters Jezero Crater - Artist's Concept

Those waters brought fine-grained sand and mud known for preserving fossilized life in comparable environments on Earth. The Martian crater's lake grew as wide as 35 km in diameter and as deep as 30 m.

I found this old(ish) paper about #JezeroCrater and the delta really educative and accessible even when #IAmNotAGeologistTMBut

Schon et al. "An overfilled lacustrine system and progradational delta in Jezero crater, Mars: Implications for Noachian climate"
https://www.researchgate.net/publication/258688201_An_overfilled_lacustrine_system_and_progradational_delta_in_Jezero_crater_Mars_Implications_for_Noachian_climate

A lot of substance and recognizable features in almost every figure, some examples:

Fig. 10: Escarpment of the deltaic deposits truncates a scroll bar. The orientation of this meander indicates that the direction of migration was proximal (toward the watershed, away from the escarpment). This orientation requires a more extensive delta in the past.
Fig. 12: Scroll bars. Numerous scroll bars (lateral accretion topography) are observed adjacent to Belva crater on the delta plain and stratigraphically below erosionally-resistant materials interpreted as channel sands. These features (A–H) result from the development of point bars at the inside of distributary channel meander bends. Arrows indicate the direction of channel migration. Unconformities in the scroll bar patterns are common and suggest successive channel migrations.
Fig. 14: Channel deposits. (A) Stratigraphically above the scroll bars and epsilon cross-bedding are elongate erosionally resistant materials interpreted as channel sands. Consistent with the interpretation of a more extensive delta in the past, these channel sands would have been deposits in distributary channels sourcing more distal depocenters, and are high-standing because they are more erosionally resistant than overbank deposits. (B) Channels sands are mapped in green, scroll bars in blue, and craters in purple.

Trying new ways to visualize the #JezeroCrater delta chronology suggested in this preliminary paper
https://www.hou.usra.edu/meetings/lpsc2023/pdf/2067.pdf

I've animated the classified deposits in their rough form and with the estimated timeline. #PerseveranceRover is currently traversing deposit 'k'.

#IAmNotAGeologistTMBut

Animation of handdrawn deposits matching those in the paper's map, gradually appearing according to the suggested timeline.
