“so the flag appears as “normal””
That’s a flawed process too. After all, if Mars’ atmosphere has a reddish hue (which seems to be the case), then if you were on the surface, the white in the flag logo would not appear white, but reddish. Therefore, correcting the photo to make it appear white would not give you the true colors as they would appear to you on the surface.
The normal hue of the sky during the daytime is a pinkish-red; however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown "butterscotch" color . On Mars , Rayleigh scattering is usually a very small effect... Since Mars is at roughly 1.5 astronomical units from the Sun, the amount of light on the surface is about half that on our planet. Under low illumination conditions, our eyes shift sensitivity towards blue because we change from using color-sensitive “cone” cells to color-blind “rod” cells. This is known as the Purkinje effect. Hence, the first astronaut landed on Mars would probably describe its sky even bluer than one might expect.What color is the sky on Mars? Astrophysicist Santiago Pérez-Hoyos about the Mars' atmosphere, Pancam instrument, and Purkinje effect. | FAQ | October 19, 2016The atmospheric pressure at the surface of Mars is about what is found at 40 miles altitude over the Earth.
Did they ask her, “What’s a ‘chalkboard’?”....................
Which would kill you first if you were kicked out of an air lock naked on Mars Remember a habitat on Mars would not be kept at 1 standard Earth atmosphere. It would be more likely at the pressure of a airliner at 30,000 feet which is the air pressure at about 7000 feet.
Freeze to death
Blood boil
Asphyxiate.
Brain hemorrhage/stroke.
Remember that there are no Earth habitats on Mars, and that the surface conditions won't support anything other than microbial life -- no humanoids, no insects, none of Arthur C. Clarke's banyan trees.
:^) Nope, because then they'd have to clean the erasers. At least they'd wind up with some job skills.
It was of course a hypothetical question.
I haven’t seen a ‘chalkboard’ in a school for decades.
All ours use dry erase markers now...................
The pressure is equivalent to Earth at 100,000 feet. The atmosphere is predominantly carbon dioxide, but at that pressure it doesn’t matter. Your blood boils as you asphyxiate, without a pressure suit.
Ah, now I see, there was no q-mark, so it liked like a declarative sentence, though confusing.
Maybe Bug wasn’t there
“Don’t let out Yog-Sothoth” how many times do we have to tell them not to leave the Eldritch abomination pen open!

So there are probably “insect/reptile like creatures” there.
Run away when you read this sort of thing.
If we suppress all discussion, all criticism, proclaiming "This is the answer, my friends; man is saved!" we will doom humanity for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before. - Richard Feynman
