Astronauten stehen am Südpol des Mondes vor einzigartigen visuellen Herausforderungen

i don’t think this is a huge technical problem… ambient light sensors, fancy full spectrum LEDs and electro tinting visors… similar conditions should be easy to recreate on the ground.. it just has to be automatic, they can’t be fiddling with knobs.

[Electrochromic devices](https://en.wikipedia.org/wiki/Electrochromic_devices) change light transmission properties in response to voltage and thus allow control over the amount of light and heat passing through.[^([12])](https://en.wikipedia.org/wiki/Smart_glass#cite_note-Nature-12) In electrochromic windows, the material changes its [opacity](https://en.wikipedia.org/wiki/Opacity_(optics)). **A burst of electricity is required for changing its opacity, but the material maintains its shade with little to no additional electrical signals**.[^([13])](https://en.wikipedia.org/wiki/Smart_glass#cite_note-Mortimer-13)

shadows are really dark when there’s no atmosphere.

„It is very easy to see in the shadows after you adapt for a while,“ noted Armstrong. But, added Aldrin, ***“continually moving back and forth from sunlight to shadow should be avoided because it’s going to cost you some time in perception ability.“***

They had just landed at Fra Mauro and were busily unloading the lunar module. Out came the ALSEP, a group of experiments bolted to a pallet. Items on the pallet were held down by „Boyd bolts,“ each bolt recessed in a sleeve used to guide the Universal Handling Tool, a sort of astronaut’s wrench. Shepard would insert the tool and give it a twist to release the bolt–simple, except that the sleeves quickly filled with moondust. The tool wouldn’t go all the way in.

The sleeve made its own little shadow, so „Al was looking at it, trying to see inside. And he couldn’t get the tool in and couldn’t get it released–and he couldn’t see it,“ recalls Mitchell.

„Remember,“ adds Mitchell, ***“on the lunar surface there’s no air to refract light–so unless you’ve got direct sunlight, there’s no way in hell you can see anything. It was just pitch black.*** That’s an amazing phenomenon on an airless planet.“
