V Martín @sharponlooker.net · 17/09/2026Here's the area in MUTED, the crater is visible in the HIRISE 2021 and 2024 footprints. The surrounding hills are a good reference point in the huge HIRISE strip: https://muted.uni-muenster.de/?x=76.196&y=18.950&z=2413&ch=11.9&cp=-89.1&d=102&b1=18.9443&b2=18.9565&b3=76.1921&b4=76.2018 120

V Martín @sharponlooker.net · 14/09/2026No need to apologize, we've had quite some fun with it, my wife thinks we should name the mini-crater Martiny 🤣 It's an honor to be of help! I noticed that fig S6 places it NW of impact e, but I believe it closer to c. Irrelevant to the science I'm sure, but may get someone to scratch their heads 😉 010

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
