Mariner 9, the first spacecraft to orbit another planet, was launched en route to Mars on this day in 1971.

Mariner 9 completely changed our thoughts regarding Mars. Its cameras examined major features including Mars’ polar caps, the Valles Marineris canyon, and moons Phobos and Deimos while also noticing evidence of flowing water in Mars’ ancient past.

What color is Mars?
We’ve all seen images of the surface of Mars, but chances are, the color has been altered in some way.
The above images are in raw/true colors, so if you were to pull out your trusty smartphone to take a picture, they’d look like this.

Many images are balanced before they’re released. Some exaggerate the redness of Mars, some are white balanced to make it appear more like it would if the terrain were on Earth.

Similarly to Earth, the sun changes throughout the day, giving the landscape different colors depending on the sun’s position…but the colors are opposite of Earth’s. Daytime is reddish pinkish colors, sunset/sunrise are blueish colors.
Mars is also a lot darker than Earth. The daytime brightness of the sun is about like it’d be on Earth on a heavily clouded day.

Blue Sunset on Mars

On April 15, 2015, the Curiosity rover witnessed this blue sunset over the crest of Gale Crater. Why does the Martian sunset appear blue?

It’s not a camera trick or an interplanetary Instagram filter. Due to their particular size, the gas molecules in Earth’s atmosphere scatter short wavelengths of light (blue and violet) away and allow long wavelengths to pass (red and orange). This scattering makes the midday sky appear blue away from the sun, and makes our sunsets appear red or orange as the light passes through more atmosphere on the way to our eyes. 

The Martian atmosphere, on the other hand, contains dust particles of just the right diameter to scatter red and orange light and let blue light pass by, sort of the opposite of on Earth. Hence, a slightly sapphire sunset.

anonymous asked:

for future reference, what kinds of constructive crit would you be looking for?? or even if you're up for criticism at all?? just so we dont accidentally offend you; there are lots of people out there that are bad at or not educated in how to properly give criticism.

This is a great question friend! Thank you for asking~

I love constructive criticism. I love advice. I’ve never had the opportunities to take formal art classes or anything, so I’m on my own as far as learning goes, and getting pointers from different people is really important to me. 

But there’s a distinction between constructive criticism/advice and flat out telling an artist how you want them to draw. Just telling me what’s wrong with something I draw, or what looks bad? Yeah, I probably already know, so that doesn’t help me at all. If you want to send me criticism, make sure it’s constructive. My coloring sucks? Okay, don’t just tell me my coloring sucks. Give me links to tutorials, point out specifics and give tips on how to improve/things I can try. 

Also, please, if you’re going to send me critique, do it off anon. There is a 100% chance that I won’t be mad about it. If you send me vague, confusing things on anon, its not gonna sit well with me. It’s so much easier to clear things up when I can talk to you directly. 

I know it takes a lot for some people to come off anon, but it takes a lot to post art too, so just keep that in mind.
