How Much Do Rockets Pollute? Are They Bad For Our Air? 

Introverts: I was born for this

As a major introvert, when I read about the psychological issues a Mars mission faces, most of the listed problems look like major benefits to me.

@@thejimmydanly As an introvert myself, i rather be isolated, especially on another planet. Plus I am onboard with Elon's " I'd rather die on Mars, just not on impact" thing. I-got-hit-by-a-car death is boring.

The introverts often forget that they're anything but alone on Mars. Pressured and temperature-regulated real-estate will be a scarce commodity during the first years (decades?) on Mars. You'd be sharing a small habitat with dozens of people with very little privacy. Think Antarctic research station or submarine, not city apartment or loft. Oh - and pretty much no Internet as bonus - no Netflix, no YT, no Disney+, no Snapchat no TikTok.

lol before the "event" and after the "event" my life is more or less the same so far, stay at home all day, and only go out when I must get things... I think I've spent years training for life in space lol jk.

He makes the music as well, I think it's really cool.

Yes

the effort behind each of these videos is mind boggling- you're doing an amazing job tim

MMMMMMMMMMMMMMMMMMMM, A WATER DELUGE

It's an idiots answer to complicated problem. Elon is a scam artist. Watch Thunderfoots videos about Elon.

@@Rainaman- bruh

@@fl488 who?

6 football field is not that much in my opinion, thought you were going to say size of NY city.

@@sevencostanza3931 its not but you also need all the batteries to last for at least a few months with no input power which we do not have enough batteries in the world to do that yet. I believe that nuclear (fission or fusion) would be a far better option with these planets powering CO2 removal systems as well as most of the world. the waste from these would only be about a football field stacked 50m high. Though the waste removal or processing must be improved. Thorium reactors may help with this though

Insert picture of Tim 50 years in the future, where he's still Not done Researching

Next video is going to take him until next year.

Super easy, barely an inconvenience!

I'll start chiseling the tombstone

True

Simple questions have some of the longest answers. Some even have whole fields of studies dedicated to them.

I take it you're new to the channel. I recommend the equally long video about the different types of rocket engines

And he didn't take the manufacturing into account. ^^ That's why people do 3 to 8 years PhD to answer a question.

CO2 to CH4, can home solar do that to run small engines? Big CH4 plants can power gas turbines etc? Methane powered container shipping? Pollution from latest rockets is so small. Thanks for the numbers.

The lovely life of studying through problem oriented project work 😂 my life for the last 4 years

That is so true. Well done Tim! Keep them coming.

whilst playing kerbal

Just found this channel and I'm impressed

True true, I didn't realize that it was that long before I read your post. Again I love these videos.

or smoked weed

I might just make a list of people, but he works really hard on these for sure. You know, considering this video is an hour long. Why can't you be more like chris random, he is like two comments down.... ps. what is your stance on politics. :)

whats so funny tho? peace

Go for it man! I know nothing about atmospheric physics and would love to learn some!

Yes, give me those vids!

You only have other stuff on your channel. Boring stuff like survival, sports and drones. Where are those sweet sweet lectures???

Weatherwax 😂 sorry my bad, let me whip one up for ya 😘

You should do both!

yea, same I am only 30 minutes in though

55 minutes...

I wish I knew how to boost this comment somehow!

Big thanks Lisa, Tim seemed pretty well informed about the basics of climate - sadly quite rare because of all the partisan shouting that goes on - and I'm guessing that is largely due to your work ( plus Tim having the sense to employ someone do the research ).

Thank you Lisa

Thanks! :D

Lisa Stojanovski Finally got a chance to watch this in it’s entirety! Great job, Lisa! Hard work pays off! Good work as always, @EverydayAstronaut!

Yeah, how do you think SpaceX are turning out so many Starship prototypes?

how do you get the seeds

@@small_SHOT they are stored in the copvs and when rockets explode and die, they fire their copvs and make them go in every direction spreading seeds

@@small_SHOT in nasa’s secret vault

yes you can grow rockets in your backyard using a hydrogen bottle and then just wait around 3 years and you have a rocket

You'd then have to be careful not to launch yourself into orbit by accidentally hitting the throttle :)

I have always thought leafblowers were the most stupid, anti-environmental invention ever. Use a rake!! An LB has no advantage over a rake at all. It's not even faster or easier to use. You can't even gather the leaves together for composting with an LB! People typically just blow the leaves off their property and onto the road. Stupid.

@@DunnickFayuro According to the back of this here envelope, you'd hit Mach 1 in 0.3 seconds. Now THAT is a leaf blower!

@@deanmichalos6848 corded electric models not that wasteful, the idea is that your blow all the stuff into a pile, then use your rake & shovel to load the stuff into the yard waste bin // if you for example use a push reel mower (hand foot human power rotary blade) to cut grass & want to clean up the grass clippings, a rake does not really work very well, but an electric leaf blower in yard vac mode works great // after your blow all the grass into a pile to suck up //

@@deanmichalos6848 always felt same.

Watch the aerospike video it's longer and better

Hahaha "Ken Burns" haha

I know right lol

Kerbin is 10 times smaller than earth

@@zhurs-mom Its a game.......?

@@Teddy-bg3bo yeah, Kerbal Space Program, great game to wrap your head around rocket science.

My Kerbin doesnt have ice caps anymore

@@EverydayAstronaut Nice video!, here some questions and some things that you might add: 1-Why you use the case of a single starship without the booster for long range passenger transport? Elon used the booster for that, not sure that an starship loaded with 400 passengers (around 50 tons of payload) could reach very far being reusable. I don't know, I am asking. 2-Water vapor is not even comparable with co2, it is a more potent greenhouse gas, but it last only from days to few months (depending the altitude) vs hundreds of years of co2, then we also consider that most of the emissions happen at lower altitude instead at higher altitude. 3- Electrolysis does not consume much energy, today electrolysers are at 90% efficiency, current liquefaction plants are at 70% efficiency, but just scaling up (which you need to make rocket fuel) you can have a plant with 85% of efficiency. One more case, you need to store solar and wind energy one way on another into hydrogen to solve the seasonal disparities and to clean the other 50% of global co2 emissions that came from the utility transport sector and the natural gas grid, those thing can not be solved with batteries (is not practical neither cost efficient). 4-You mention how many football fields of solar panels are needed to make enough fuel for the starship on mars, but you did not mention how much time it would require to fill those, is not the same that amount of panels to refill a starship every 1 month than every 2 years.

Everyday Astronaut why does this comment have 1 like and no comments?

Well the dragon 2 capsule can actually handle 7 passengers, Ik it has four seats for ISS config but it can be configured for seven seats

Um, I think we need another video on that.

New video out today from SpaceX, using a booster

Of course there should feel use when the Starship

I like how you can call it a documentary it’s just that good

TV? What is that? :)

True

Ps zzz

Completely agree - this is my go-to for info on space.

Java Man True. Rockets do not launch frequently either so rockets are one of the last things to worry about

14rs2 Depends on the Rocket. Anything using hydrazine (UDMH, MMH) and di-nitrogen tetroxide are pretty bad no matter how you look at it. The fuel and oxidiser are both extremely dangerous and their by products are extremely dangerous. They are also hypergolic. While it’s not pollution in the generally accepted sense (growing problem, contribution to global warming, etc.), all of those things post immediate problems before, during and after launch. But they are used because they still give very good performance.

Rockets are not a problem if we continue to use them as we do now, taking payloads to orbit. If we try to implement Elon's dumbass idea of replacing airline travel with rocket travel, then the number of launches increases to the point where it becomes a huge problem. The ozone layer would be decimated by thousands of re-entries a day. But as long as Elon gets his daily fix of Twitter attention, he doesn't care if his ideas are feasible or not.

Rockets aren't the problem yet. And that is why now is the perfect time to discuss those issues so the companies don't start their usual song of how much it would cost and the economic loss of switching to better methods, like those people always do when left unattended for to long.

@@javaman4584 Like Joe Holland stated, they aren't "completely unregulated" but definitely aren't without their issues either. Like in certain territorial waters strict rules are supposed to be in place with regards what one can do with the various byproducts leftover after water and fuel filtering. I don't know if it's strictly speaking legal to dump certain of those things in international waters or other places with less strict regulation, but let's just say I wouldn't be surprised if quite a few companies save some money doing it the easy or cheaper way. I'd definitely consider it to be a sector where improvements would be meaningful.

Muhaha I'll spoil it for you IN THE END HE TALKS ABOUT HIS MERCHANDISE STORE

True, but I have nothing to do tomorrow so away I go

Bitch just watch til 2:00, bit of persistence mate

@@sheggle Actually 01:52 now and I just finished watching the video :D

this... lol.. i thought that this is gonna be loooonnngg video (well,, it is), lets watch it for a few minute... and i suddenly realise,,, i watched the whole video xD

Every single video lol captivating stuff!

That was my same reaction and I immediately started watching it!

@HO LAM YIU lol

*_And today on, Things That Totally Happened_*

@@hypeninja4786 I started asking questions on space and creation at 10 some kids are really curious

@Lewis Massie: well done on the 11:30-ish pronunciations

TTS can easily help with these. I'm sure he made use of that. I do it all the time.

this is funny

thats hilarious

it's a drop in the bucket now. but with all these space travel plans, eventually there "will be" multiple rocket launches per day. what does the pollution look like with 10 per day? 20? by the time a group of starships reach mars you've launched hundreds maybe thousands of rockets in a short period of time. im sure you will find a way to ignore this and keep cheering on for space travel.

Hahaahah

It's been a long time in the making haha

Followed by hitting 'replay' to make sure you didn't miss anything the first time around!

ronn kelley haha

Me: only videos

Yep

Yep yep

Okay.... What's your opinion on the vegans.

Check @TheUrbanist his channel is about architecture, art, food and travel. He has the same policy.

Pollution is politics.

Ha! Yep, and how many commented before having watched a significant portion of the video :)

Far too long I skipped 98% of it

As much as I’d love to watch the whole thing, there are countless other hour-long things I’d prefer to do instead.
