Finally drove away from Pahrump Hills on sol 923. Wheel tracks sure are piling up at the end of the drive -- there seems to have been quite a bit of slip.
[admin note: I was going to start a new thread for this, but realized our thread naming may be a bit out of whack because we're really not journeying to Mt Sharp anymore, are we? We'll discuss it with admins and I'll move/rename posts when we figure out our naming schema.] -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

A (probably failed) attempt to find fluorescence in the Sol 935 MAHLI night shots:
Starting from this Sol 935 MAHLI white LED night shot, RGB channel-wise histo stretch returned this image: ![]() Starting from this Sol 935 MAHLI uv LED night shot, perliminary cleaning by subtracting a Sol 910 night image without LED returned this image ![]() then RGB channel-wise histo stretch returned this one: ![]() Subtraction of the histo stretched white LED image from the cleaned and histo stretched uv LED image returned this image: ![]() Histo stretch of the difference image returned this result: ![]() In the latter image I wasn't able to indentify fluorescence or phosphorescence uniquely. Most variations are probably due to shadows and slightly different positions of the LEDs (my preliminary interpretation). |
