Reposted by V Martín Simeon Schmauß @stim3on.bsky.social · 18/12/2025Mine was only a proof of concept, so I'm glad someone at NASA made a more refined version. Their version apparently fuses more streams of telemetry to represent the true rover position at very small intervals, while mine was limited to only the Navcam image locations that were interpolated. 131

Reposted by V Martín Tim Demko @timdemko.xyz · 09/09/2025After poking around and finding the base of the flow, the story became much richer: the basalt had flowed over some eolian dunes which sourced the water for the hydrothermal system. The sand might have accumulated as obstacle dunes around a bedrock hill, then buried by the flow in a valley. (2/2) 3122

V Martín @sharponlooker.net · 07/04/2025Exquisite work! 👍 I took the liberty of rotating the 2nd one a bit, it gives a better sense of orientation. The detail and the lightning are great input for seeing how some of the small features that might look like the leopard spots from Cheyava, are probably impact spherules in this case. 010
