December 21, 1968 was the launch of Apollo 8 and I was there as a 17 year old boy. After the launch, I could smell kerosene. I was 18 miles away. Pollution? You tell me..... Visually the Saturn 5 first stage burned cleaner and dissipated faster than a shuttle launch with it's two huge SRB's. They almost blocked out the sun. But an RS-25 (Hydrogen fueled) exhaust is very clean......So is a Spacex Raptor which runs on Methane. (And is MUCH cheaper than Hydrogen)

Hey Tim, ever think about making a video on the impact of rocket pollution on the ground? Kennedy space center, wallops flight facility, and boca chica are all on fragile wetlands and I've always wondered what kind of actions they take so as to, you know, not murder everything in the wetland. I only really thought about this after seeing crowd videos of the SN8, 9, 10 test footage and hearing SO MANY DIFFERENT KINDS OF BIRDS and it made me wonder how they plan on expanding Boca Chica (or any other coastal launch facility really) without causing intense environmental damage

Waker of Winds Pirms 2 Stundām
@Troy Savary Ummm.... Perseverance got millions of views. I personally really enjoyed it. The way you're framing it is that people don't like NASA anymore. NASA is a government organization. They aren't in the business of trying to be a hype machine. They also aren't as active as SpaceX in doing new things. I'd say that if anything, more people are interested in NASA because of SpaceX. The problem is you can be interested in NASA, but not a fan of them really like you can of SpaceX. Unless you're constantly watching NASA TV, the only constant source of space news is SpaceX. When other companies or NASA do something, we happily talk about it. I personally love all spaceflight stuff.

After all, rockets are not that huge things compared to oil industry and other sources of GHG's. And without rockets we would not have earth's observing satellites that are helping to measure other emissions and what really happens with our climate. But even rockets can do better and make less pollution. Let's also hope that Musk or others won't mass produce rockets that will become a really significant emission source.
Mikko Makela
Mikko Makela Pirms 7 dienām
Steel should be produced by using hydrogen. Then emissions will go down a lot. We just need to get hydrogen prizes down.
Mikko Makela
Mikko Makela Pirms 7 dienām
Methane powered rockets may release double COe-emissions on launch. If you overpressurize the rocket fuel for better performance then you may have some unburned methane that leaks to the atmosphere. If that amount is around 4% then it means you get 25-times more potent GHG to the atmosphere and 4% times 25 is: +100% vs. pure CO2 burn.
Mikko Makela
Mikko Makela Pirms 7 dienām
What about the whole system that runs? You have plenty of build infra around the rocket and if the rocket is not reusable then you have to manufacture them again and again. Hardly ever you'll see the whole combination of the system, but only one part of it. And by mass the rocket itself is a tiny part of the whole organisation. And in space technologies you use loads of rare materials that has to be taken out from the earth crust. This adds quite much pollution to the equation. Without rockets you won't need any of these, so they should be added as a rocket waste. The launch is most likely a minor part of the pollution when compared to the whole industry around them.
Mikko Makela
Mikko Makela Pirms 7 dienām
Methane leaks are just pure methane that comes out from all along the methane manufacturing, transporting and fueling. Also the burning process is not always burning all methane, so there's another source. And also with failures like Starship landing failures you get extra methane leakage. Same issues effects almost any gas. Global methane levels are raising rapidly and one source is fracking industry with long pipelines.

The CO2 emissions of rockets should not be our primary concern here, because of their relative limited use, at least for now! What is way more alarming: The hardcore poisons like aluminum-oxide and chloride, which are not only spilled into the lower atmosphere, but also into the upper atmosphere thanks to the use of Solid Rocket Boosters (SRBs). SRBs should have been banned as a health hazard a long time ago as it effectively borders on chemical warfare! Luckily, the Space shuttle is grounded! Unfortunately, the politics surrounding the stupid SLS Rocket will ensure that these SRBs will stick around for a while still! Hopefully not for to long!

I would have liked for there to more emphases on the health concerns of rocket emissions to humans. What effect would Starship launches have on the air pollution index for towns or cities there are near? Climate scientists will typically preface when talking about CO2 that it is a very mild greenhouse gas with water vapor being a much more powerful greenhouse gas. Water vapor overlaps the inferred blocking wave lengths of CO2 except for a small window and is some 45 times more concentrated in the atmosphere. A note: greenhouse gases as typically discussed block inferred radiation from the earth's surface from escaping out to space. Their interaction with solar radiation is not a big topic of popular discussion. Water vapor and steam are invisible. Condensing water vapor and steam appear white as seen during rocket launches. CO2 in the atmosphere converts high energy ultraviolet solar radiation into longer wave lengths more conducive to heating the earths surface. This is CO2's primary means of heating the earth and is thought to provide the earth with some 50°C of additional temperature. This takes place with very low levels of CO2 at 10 - 50 ppm to reach saturation with present day concentrations being around 350 ppm and there is no ultraviolet radiation in the wave length CO2 does this conversion hitting the earth's surface. There is a giant spike in the CO2 converted wavelengths hitting the earth's surface. This is NOT a greenhouse gas mechanism. As a greenhouse gas CO2 has a natural log relationship with larger concentration having smaller effects in radiation forcing and may go hyper log rhythmic at multiples of todays concentration. CO2's forcing effect is small at some 1.4 W/m^2 inferred energy retention predicted by an attitude of 20 km for an increase of CO2 from 250 ppm preindustrial to 350 ppm of today. As a comparison a solar panel is typically rated at a solar radiation of 1000 W/m^2 and on a typical good day will see 500 W/m^2.

Fossil fuel is the most extremely limited resource of power over any other alternative engine of travel, even though its the most powerful and unsfable exertion in its duration then anything else. Because of bulk limit canister, its even more dependent on aviation gears like wings/gyros/propellers and/or other altermative fuel preserve methods, until we learn to use more EPA/Eco freindy combustion booster, or other flight concept paderns when traveling within the Earths Troposphere.

The anti-gravity warp drive comments are pretty stupid but to claim there's no alternative to chemical rockets as we use them now, especially for stuff like interplanetary missions is pretty ignorant I'd say. Both Atomic rockets and various electrical propulsion systems are proven technologies that are a lot more efficient with their fuel compared to even hydrolox type chemical engines. It's not extremely relevant to the topic of this video but I feel I have to point it out.

Very nice Video, but of course there are some slips that, in all fairness, you can not avoid completely. If you compare Rockets to Airliners, then you have to look on their practical and societal uses. There are so many airliners, because they serve a purpose to society - a purpose that in wide parts can not be replaced by rockets (midrange travel). So just putting the different numbers up there rather becomes a part of an "whataboutism", You could equally excuse *anything* with that argument that just happens in a niche, like car racing / racing cars on public streets, military emissions, etc. pp. The question is not: "Has this a large percentage on overall pollution?" but "is this additional pollution worth the purpose it serves". Almost nothing apart from general transportation, electricity generation and heating has large impacts on pollution, if singeled out - but the sum of the small niches still delivers a huge part of overall pollution. So - you just can't absolve Rockets from producing emissions by saying "there are not that many of them". If a rocket is used as travel devices for millionaires to have an exiting "holiday in space" than its emissions are completely avoidable - this serves virtually no benefit to society. It just would be a totally unneccessary purpose, a sign of pollution as a right to a decandent elite. This is of course also true for yachts, etc. - but this is again a whataboutism and would do nothing to justify Spaceflight as a thrillride for millionaires. E.g. Bransons complete "space"-company is nothing than an elaborate amusement park ride... Of course some rocket starts serve important scientific purposes - but manned spaceflight in general would be highly debatable in this discussion - a mars mission with its thousands of neccessary rockets starts during the programm leading to the final mission could also be debated in its use to humanity.

I had an idea from along time.... What if we lauch rockets from a higher land, like mountains? I mean, it would be away from public, as well as, u would save on alot of fuel!
Harshit Singh
Harshit Singh Pirms Mēneša
@40hup firstly, the rocket scientists, or, any famous person in general, is a normal person - among us. It's not a compulsion to be in space industry - to get a good idea. Secondly, although what u r saying is true, but even then, it would cut off like 3-4 miles thick atmosphere straight away! And, not all, but atleast, some fuel would be saved! Because, u r nullifying the drag caused by 3-4 miles of atmosphere, along with the 3-4 miles of distance. And, there are more advantages to that. Firstly, u get a cool climate to work with, so u don't need to be worried about overheating in a few cases, like cold temperatures to safely store cryogenic fuels in their respective tanks. Secondly, geographical places with such high altitudes are generally less populated. Thirdly, although a little bit vague n has negligible effect, there would be lesser gravity at such altitude(not a lot for us, but it may save a few litres of fuel in rocket - which can change alot, as EVERY GRAM MATTERS) And if we do so from a mountain near equator (as u say), then, it's a lil more sensible...
40hup
40hup Pirms Mēneša
No, you would not. The energy is in large parts not used to "lift" the rocket up, but to speed it up to orbital speed (~28.000 km/h). Rockets do not fly "straight up", they go more horizontal pretty soon after they start. It amazes me, that after decades of rocket science people think that "starting from a mountain" would be an idea that nobody in the industry had already entertained - and obviously discarded it... In fact the best starting points are around the equator - there you can use the "sling" effect of the turning earth which is far greater than "starting from higher up". Same is also true btw for any "catapult-launchpad" ideas - that does not have a large fuel-saving impact in general.

Great video but I don't think it makes sense on any level to compare the number of launches with the number of plane flights. the purpose is totally different. We should reduce everything where the use to pollution ratio is bad. For example I use bamboo toothbrushes. Is it one of the big pollution problems in the world? Probably not. But how hard is it to do that instead of a plastic toothbrush? well they are not more expensive. The only disadvantage if you desperatly try to find one is the less comfortable handle. So bad ratio for using plastic toothbrush over bamboo one since they cause a bit of pollution but the use is no price advantage and no real benefits aside from the handle thing so easy to get rid of it. When it comes to planes we have to watch how big the use of a flight is and the same goes for rockets but again the purposes are very different and at rockets it seems to be quite complicated to calculate. So we should think about which of those satellites we really need up there and which we don't. We also should think about if we really need the starship transportation system for people over regular airplane flights unless one day they are ecofriendlier than planes.
