How Blocking the Sun Makes Mars Hotter

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.

Huh. Turns out Mars really DID need M.O.M

[Blabla]

Also the Indian space craft was extremely concerned whether you were wearing the sweater they gave you!

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.

This is really interesting, I'd never considered a dust driven climate but it makes sense if we think of weather as the interaction of atmospheric particles, rather than as wind, rain, etc :)

😂😂 "MOM" LOL, Mom, how's Mars doing? Can I have some more cereal, Mom? Want a cuddle Mom!... Sorry, I'm so childish

Venus: planet of lust
Mars: planet of dust

so earth has the hydrological cycle, and Mars has the dustological cycle.

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.

It's not a commercial new but it's still like the stratosphere!

"Cold, barren and suffocating..."







There's an ex-wife joke in there.

So early all the comments are terrible 😎 thanks for the vids scishow team!!

Of course the guy who comes up when you image search 'Hot Mars' is pretty hot already... must be the robes and helmet combo. Oh, and abs.

"[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.".

They don't realize the dust storms are powered by electrostatics. The surface and ionosphere acts like a capacitor, it is charged by solar wind.

We need to divert a small ice body to crash into Mars. Or perhaps just into close orbit so that it decays gradually and sprays its water into Mars' atmosphere. There ought to be plenty of such bodies out around the orbit of Pluto.

If shell is sand I can't imagine how much glass can be there

[xsauce]

Mars is at opposition at this point in time

[AceSpadeThePikachu]

Hmmm...I wonder if future colonists on Mars will be able to find a way to use these dust storms to start teraformong the planet. Maybe pump a whole lot a really dark carbon-rich ash into the atmosphere turning the dust storms pitch black to absorb the maximum amount of sunlight possible.
