How Blocking the Sun Makes Mars Hotter

Pre-order your MOM pin all this month here: dftba.com/scishow
If we’re going to send people to Mars someday, we’re going to need to be very conscious of the challenges presented in this endeavor. And at the top of that list is the ferocious nature of dust on the barren planet.

    MOM entering Martian orbit: Why aren't you married yet? Your cousin Saturn has the most lovely ring. Even Uranus has one. I'm not detecting any signs of life down there. I just came from your sister Earth, eight billion kids now. And why didn't you go to medical school? Mercury can take temperatures, so can you.

    I was originally thinking that the dust acts to “thicken” the atmosphere, and disallowing the radiating of heat back into space. But one question sticks with me, was the orbiter measuring the temperature on the surface or the dust suspended in the atmosphere where it has absorbed additional heat and retains it as it’s a thermal mass.

    "[due to its] much thinner atmosphere, Mars's dust can hang in the air for way longer than Earth's usually does" -- the other reasons make sense, but that seems counterintuitive. Seems like thinner atmosphere means fewer air particles to provide air resistance preventing dust from settling? And indeed the Wikipedia page for "martian soil" says "Similarly sized dust will settle from the thinner Martian atmosphere sooner than it would on Earth.".

    It's _way_ easier to terraform even when terraforming is as hard as it is. Building a planet from scratch would be monumental. If you could redirect ALL the trillions of asteroids that make up the Asteroid Belt (making sure to collide them at low enough velocity that they coalesce) then you'd still only have a body 3 or 4% the mass of our Moon. en.wikipedia.org/wiki/Asteroid_belt

    All the friction from collisions would produce a ton of heat. Mars was warm, then cooled down. Like eating a hot pocket (or soup) immediately out of a microwave 😛🔥 If you don't build it correctly, then you'll have to terraform it too. (Earth didn't start with oxygen rich atmosphere, cyanobacteria did that, and other plants enhanced it)

    Pressure. Hot air expands, leaving a 'vacuum' with 'no pressure'. Cold thick air rushes in to fill up that 'vacuum'. That "rushing in" is the wind. MAYBE like when you wave your hand, you push air away in front of your hand, but the empty space behind your hand is filled with new air, rushing in. (My best shot. Biological sciences here, and I think air pressure is weird 😑)
