The average solar intensity at the orbit of Mars is 590 W/m2, compared with 1370 W/m2 in Earth orbit
So, for the pictures to show anything worth viewing, they must show more light than we see, that is allways used in photography but people do not notice it.
On Pluto, the light is 1/1000 of what we have here on Earth.
Thanks for the info. So Mars has a bit less than 1/2 of Earths Solar intensity.
How greatly is Earth's Solar intensity reduced on an overcast day, do you know? It is still quite bright, isn't it? We are talking about surface intensity.
Wouldn't the lack of a substantial atmosphere on Mars allow more solar radiation to reach the surface?
I do not believe it is as dark and gloomy on Mars as you contend...but that is really not the issue here, is it?
