Marveling at the world

Lots of Martian rocks and landscapes, some looking all too familiar, but don't be fooled by that: Mars is an inhospitable toxic planet. Let's not mistake fiction for reality.

I like dirt and rocks, but I Am Not A Geologist (IANAG).

Until life (past or present (!)) is found on Mars, rocks is all we are gonna get 😀

Yes, both Deimos and Phobos were visible at that time (UTC: 2023-04-26T04:27:34) in that orientation. What we see is probably the larger of the two, Phobos, which was also higher up in the sky. The camera was looking at 30° elevation, 90° azimuth, and that's close to where Phobos was.

Maybe this is the first time Phobos is viewed in daylight from a rover on Mars? 👍 !

Great memory @PaulHammond51 !
Then maybe, "the first time Phobos is viewed in broad daylight from a rover on Mars"? 😀 A few minutes before it took that image it had captured the sun:

Great news for anyone working with the Perseverance raw images!
A longstanding issue was recently fixed that applied a linear stretch to the public raw images.
This made it nearly impossible to work with the tiled Navcam images.

I suspected something had happened because I no longer had to manually adjust the color of parts of my auto-mosaic images.

Your Twitter thread probably played a role, in which case it once again proves that takes user reports seriously.

Great job! 👍 !

The other week I saw @65dBnoise's Mars Trilogy maps https://mastodon.social/@65dBnoise/109849270626537378 via @elakdawalla. I've adapted them into an interactive, zoomable, map as an illustrative example for a visualisation package we are making for work: https://open-innovations.github.io/oi-lume-charts/samples/map/zoomable/#example-9 The zoomable map makes use of OpenPlanetary's nice base map tiles.

It turns out the flew a complex flight path (re: https://mastodon.social/@65dBnoise/110249309884223213).

The map shows the official flight path and an estimated location and field-of-view (cyan) of the RTE 51-7 image posted earlier.

EDIT: The flight path may be an indication of the path may follow when it departs Mount Julian, as the almost flat top of that hill appears to be smoother than other path choices.

Angled rocks on the nearby interior wall of crater Belva.

The rock on top left appears to be about 70m away. Context map follows.

Anyone reading Kim Stanley Robinson's "Mars Trilogy" or any part of it quickly realizes that while the novels are full of technical details, there are very few maps and those that exist are very coarse.

Here are some maps I made while reading the books several years ago, showing cities, places and plot info. The background is a USGS Topographical Map from Wikipedia: https://upload.wikimedia.org/wikipedia/commons/4/48/USGS-PlanetMars-TopographicalMap.png

Corrections and new locations will be posted to this thread.
