Great video about Mars! Knowing the average temperature on the planet really puts Total Recall and Watchmen into perspective. The people exposed to the outside in both of those movies would have actually met a very chilly fate. Knowledge is awesome. Thanks for this! 🖖
A lava tube or cave at the equator with weighted clothes seems like a good place to start....would the carbon dioxide in the air at the equator be gas during the day and snow back to the ground at night?
I seen a video awhile ago about some people that had a party and threw a lot of dry ice into an in ground swimming pool some people jumped in and a couple died from the carbon dioxide they couldn't get out of pool fast enough to breathe fresh air
How can Mars temperature ever reach 20 degrees c if its so far from the sun compared to earth and no atmosphere? 20 degrees c is a nice warm summers day here and do not get that much heat in the winter. It does not make sense.
Thank you!!! At last I found a common sense explanation of the temperature and oxygen level that makes up Mars!! I’ve heard of “ mad” scientists, and if anyone thinks about going to Mars 🙆♀️
A blanket only works when you have a significant heat source inside, like yourself. It is not known how much internal heat due to radioisotopes decaying are present on Mars . The latest Mars lander has indeed an experiment to measure heat flow. So the thin atmosphere(density 0.0151 kg/m^3 at the Viking 1 landing site, mean over a 180 sol period at mean temperature of -60 C and 6.2 mbar mean pressure.) does not contribute to the cooling at the aphelion It is caused by the relatively large eccentricity of the orbit. The reflective effect of the 15 nm wavelength infrared absorption of the molecular bending mode is small due to the low ground temperature( greenhouse effect) The density ratio compared to the earth sealevel density ( 1.225 kg/m^3) is 1/81
3:10 You say that due to the cold night you would not live on Mars. Because the Mars air (~95% CO2, 5% N2) has a very low density, the heat capacity per m*3 is also very low, this makes an enormous difference, as illustrated with 2 examples: 1) An eskimo needs to heat his igloo from a chilly -20C to a cozy +20C and say the volume to be heated is 5 cubic meters. His heater delivers 200 watts. He starts out at -20C where the air density is high , as the air warms up slowly the density decreases, so some air is pushed out and needs not be heated. Using the mean density at 0C of 1.293 kg/m^3 , the heat capacity at constant pressure cp=1005 J/kgK we can calculate the heat energy required and the time it takes to reach 20C. E = 40C * 5 m^3 * 1.293 kg/m^3 * 1005 J/kgC = 260 kJ The time to raise the temperature is t = 260 000W sec / 200 W = 1300 seconds or ~ 22 minutes. Next we will determine on Mars how long the same heater will warm the interior of a closed but unpressurized rover from -60 to +20C, the interior volume is also 5 cubic meters but the temperature difference is 80C. On the next comment we will do this calculation and see how long it takes.
To complete the comparison, we first need to determine the heat capacity of the Martian air and the mean density at -20C at an external pressure of 6.2 mbar. The gas-constant for the Martian air is Rm = 8314 J/mole K / 43 mole/kg = 193 J/kgK. the first number is the general gas-constant , the second is the molecular weight of the mixture of CO2 and N2, Martian air. The ratio of specific heats k = cp/cv is 1.33 the heat capacity cp = Rm * k/(k-1) cp = 778 J/kgC , smaller than terrestrial air. The mean density at -20C is rho = 620 N/m^2 / (778 J/kgK * 253K) = 0.0127 kg/m^3 next we will calculate the thermal energy to heat the rover air from -60C to +20C
Completing the calculation: Em = 80C * 5 m^3 * 0.0127 kg/m^3 * 778J/kgC = 3.95 kJ and the time to heat the Martian air is 3950 Wsec / 200 W = 19.75 seconds! So it takes about 60 times less heat energy to warm the same volume of Martian air by twice the temperature difference than on earth. For the comfort to live on Mars the low temperatures are not relevant! It is important that machinery is not subject outside to CO2 condensing temperatures without small heaters to prevent malfunction. When the habitats are properly designed, and the dust problem is correctly dealt with , life on Mars is going to be very attractive. Very low temperatures are NOT a problem! With the new contact pressure suits not requiring the cooling systems as used on the Moon, mobility is far easier than what our astronauts had on the Moon .
Well the core doesn’t really play into surface temperature, BUT if the core was alive again it could recreate the magnetic field around Mars allowing it to protect itself from the solar wind, rebuild a thicker atmosphere and keep in heat.
So did these snowflakes land on the rover do they interfere with the camera lens or solar panels. It’s so crazy these time panels are able to run the rover across the ground run the camera receive and transmit massive amounts of digits data for photos and diagnostic data. Has the rover ever been caught in a massive dust storm.?
Bros been mewing💀💀💀
Mars may look hot because it’s color is just trying to fool your eyes, it is way colder then you could ever experience on earth 🥶🥶
I appreciate u do degrees Celsius for us non Americans, and great video as always!
We should all be using Celsius!

Great video, glad you didn’t grab the dry ice accidentally with your bare hands when during your experiment 🧪
That was a great presentation
How is this very informative video only has 1,400 views!? Very nicely done!
I appreciate the support!
I stopped watching after he said “further away” three times and “Antartica”.
Loved your video 👍
Yayy!!!
Great video man
Mars doesn’t sound so bad it’s negative 40 degrees in Chicago right now and I would finally fit the growth chart if i went to mars
Great explanation 👍👍
Fascinating
Wow... All that we wanted to know about MARS and other planets too ... Thnk u boss..👍🙏
you're welcome!!!!
A lava tube or cave at the equator with weighted clothes seems like a good place to start....would the carbon dioxide in the air at the equator be gas during the day and snow back to the ground at night?
we should be looking at the equator in Summer on Mars. that'll be the money shot for finding life.
Love your content. I wonder is 1 year in earth counts as 1 year in mars.
Hello friend I am an Indian, your talk about Mars was awesome, Congratulations💐
Thank you!!
Why is your nationality relevant?
@@markfox1545 Congratulations on behalf of our country "Even if we are divided as a nation" there is no alternative to "we are all human"🙏
I also..bro
58 ° but I can't stand that temperature. Yes, I found a new venture idea. I will establish the first ice cream factory in mars.
Long live Uncle Kevin put my heart on my comment. I will do my best to see you one day when you come back to Istanbul.
Nice video bro
thank you!

cold in north and south pole but, is there an ice there?
There is!! But it's Carbon Dioxide Ice, commonly known as Dry Ice here on Earth!
Let us bring it closer to the sun, and then just wait. What distance would be about right?
nice video
How the Rover drive there and "helikopter" fly there on that temperatures and winds

Kevin sir I like your Videos on space 😁🙏❤️
That makes me so happy!
Mars is a planet farther from the Sun as compared to Earth. In fact, the temperature on Mars is -81°C. (-109°F)
So why are we WASTING MONEY & TIME THERE!!!? / it was just -22 Here in Minnesota...Yea I want to go there.
People in Minnesota go to Mars to warm up!
*Mars'chan* is a, Kuudere.
Sir, can we build Venice beach on Mars? I'll email Uncle Elon so he can do this.😅😅😅
Hahaha
If Mars had a core like Earth, producing additional heat, not totally relying on the sun...
How would the temperature in Mars change?
Well the core doesn’t really play into surface temperature, BUT if the core was alive again it could recreate the magnetic field around Mars allowing it to protect itself from the solar wind, rebuild a thicker atmosphere and keep in heat.
@@APlaceCalledSpace Yes. That's what I was getting at.
How does a core become inactive? I'm sure you've got a video.
@@aimeefriedman822 potentially a massive collision, but not for certain.

They will Bomb the MARs in the End and come back. LOL
