Who knew that the science parts (like the 2Hot Thermometer and PresMat Barometer) in Kerbal Space Program could actually be used for scientific purposes?! Well, that is the reason why this video tries to show you what you can do with this information! There is a connection between how fast the pressure or density of an atmosphere decreases and the composition of that atmosphere through something called the scale height and the mean molecular weight! To figure out what that means, be sure to watch the entire video!
By the way, I have taken the time to actually make some nice captions/subtitles for this video. Apparently, about 8 to 10% of you use these. So to make my videos more accessible to other people I will do this from now on!

Mystery goo… iz verry yummy
Considering that the KSP system is a 10 times scaled down solar system, to make all the maths match, shouldn't you add some multiplication to the masses that the planets are made up to make things work?
Kerbal is far too dense for its size to match the gravity shown. Can't you apply that same scaling of the mass being higher to the atmosphere?
Edit:
In the maths section, it says d^2 z/d^2t, but it should be d^2 z/dt^2.
Additionally, I have taken the time to actually make some nice captions/subtitles for this video. Apparently, about 8 to 10% of you use these. So to make my videos more accessible to other people I will do this from now on!
This guy is alive? I thought he dropped off the face of kerbin
~5:40 its possible that Kerbin has an elevated amount of O3 instead of O2 compared to Earth. By how much exactly, I donβt know. That's for people who are more capable at math than me to do. : P
He has unlocked the fully potential of ksp science
really good vid!
TOO MUCH MATH!!!!!! (nice vid tho)
Worth the wait! π¨βπ
Great video to watch instead of doing my math homework
but can you tell me what element the mystery goo is? π
FALSE ADVERTIZING! I was FOOLED into thinking you'd be MAKING MYSTERY GOO in your kitchen but instead you're doing NERD MATH like a NERD! GREAT video though keep up the GOOD work!!!!!!!!!!!
What if kerbins atmosphere just has a bunch of xenon?
Eddit spelling
I think the simplest answer to the question of what the atmospheres of these planets are made of is, the developers just made things up as they went along and adjusted them until they felt right
I love watching these as a student in science and pretending that i know what you're saying 90% of the time
oh no mistakes have been made i voted yes for the math thingy but i dont understand it D=
Well, now i gotta finish my video using the presmat and thermometer to find the boundary layers of kerbins' atmosphere. Unless you've already done that.
Hmm in you derivation, you took 'g' to be a constant, while that is a good approximation for a planet the size of earth, it's really not for a smol planet like kerbin.
Kerbin's radius is 600km and the atmospheric height is 70km which is pretty significant in comparison to 600. So the value of 'g' at the edge of the atmosphere is only about 80% of what it is on the surface.
Maybe that's why we got a weird value of ΞΌ
How do you change the engine throttle?
When solving the equation for P(z), I think you assumed H was a constant relative to z, but it's not because the temperature varies with altitude.
If you used surface temperature, then your expression is valid only close to the surface and your results may be biaised (how much ? I don't know, maybe it's a good enough approximation).
I think you could first use the thermometer to have an experimental model for T(z), then use that in your equation for P(z), and finally do what you did with the barometer.
It was still a good video, I really like the concept!
My (scientific) oppinion is: We never know, it could be made of an complete unusual stuff. This is because the Kerbol universe is not like our universe in many aspects. Some planets have too much density, so you have to assume degenerate matter to fit our understanding of quantum mechanics. Moreover, if you measure the gravity below the surface you discover, that all celestial bodies have singularities at their centers. Kerbol itself couldt never ever become a star with his mass (one order of magnitude above Jupiter), especially not a G-class star. And so on…
I think Kerbol habitable zone closer in but the CO2 like on earth keeps it from freezing
