    Like the others say, dont change. Think of it like this. You're not going out of your way to make it polished sleek and sexy, and by just being yourself, talking about what you love and sharing you'r knowledge you have 1 and a quarter million people subscribing to your content, if that should'nt be a huge ego boost I dont know what should. Anyways, what is your favourite book/Author?

    Scott on the last starlink launch I was watching the video and it looks like you can see the moon in the background then it set and another one appears. What are the objects in the background?

    Personally, I like your simple "get to the point" causal format. You talking is interesting enough. it feel like I'm in your living room having a beer and listening to you rambling about rocket stuff. You do sell sell yourself short. you have a totally perfectly fine quality for what you do . I will give a example, your "going nuclear" series is one of the best series about that subject. the images, graphics, archival image are simple to the point and "efficient" ( haha). Yeah, you could be like PBS space time. but I think there is enough of them out there. I'm a Fan of Engineering Explain and it is mostly Jason in front of a White board doing math, to me this is perfect.

    Scott, a question for you. When an airlock on the space station is used for a spacewalk, it obviously must be evacuated of air before opening the outer hatch. Is this done by pumping the air back *inside* the station using a vacuum pump, to save the air, or is it vented overboard? It would seem to me the former is more 'efficient' because oxygen in space is rather expensive while electrical power is effectively free. Maybe the strategies have changed over time?

    Not sure where to post this question but here goes: Has anyone considered moving the ISS (International Space Station) to orbit the moon while we do our landings. It's already built out and has most of what they need. And it would protect the ISS from getting hit with Earth's space junk. All they need is to attach a booster to push it to the Moon.

    Adding fancy graphic and irritating background music might look as a more polished and pr0 but it's just a facade. What brings me here is the interesting content, the feel of great knowledge, fast responses to some space/rocket events, clear English (quite important for a non native), superb analysis of various "rapid unscheduled disassemblies". I get the feeling that I'm sitting with a friend, sipping tea and talking about the mysteries of the universe while on those "polished" channels I feel like watching a TV ad or a cinema show, lack of connection there. Keep flying safe!

    Scott, Always enjoy watching/listening to your videos - the accent is a little familiar too. As a boy I used to visit Armagh Planetarium. If you were wondering about topics for future videos, here's a couple of ideas. Now that Starship is going to get to the Moon at least once, what should 2 astronauts take and what should they bring back? What kind of boxes might be used to test how corn, or wheat or grapes, might grow - with some kind of window allowing "friendly sunlight" without the deadly radiation? I thought returning several tons of lunar material would be good. Though with only the Orion capsule, not so much. What would the mechanics of getting a Lunar Starship to a place it could meet with a ground-capable Starship to transfer a hefty payload? Seems it would be helpful for people on earth to figure out how to make things like concrete on a large scale, to design some useful mining equipment. How would "earth-moving" equipment work on the moon? Seems 1/6G might have unexpected effects - at least to some people used to 1G. Challenges of such equipment working in a vacuum - no convection cooling, only radiative cooling? Tanks of liquid nitrogen, oxygen, or amonia as heat sinks? How to deal with Lunar dust? According to the astronauts it got everywhere, and was extremely abrasive. Can't just spray water to keep the dust down. To act as a shield against radiation, micro meteorites and the likes, seems an living below the Lunar surface would be good place to be. Is it really? How deep would a place have to be to reduce radiation exposure to normal shirt-sleeve environment? New application for Boring company tunneling equipment? Hope some of those questions, might be of interest to explore/talk about

    Have you tried the Spiffing Brit's youtube algorithm gaming? NOprojects might have fixed it by now, but pretty much all of the NOprojectsrs I follow from Linus Tech Tips, to far lesser known NOprojectsrs participated, and some got up to a million extra subscribers. I'm sure NOprojects has probably fixed it by now, but it's a thought, and a good 20+ NOprojectsrs that I personally follow took good advantage of it, in addition to several dozen that I wasn't previously aware of.....

    Don't make it a professional thing. The format of your channel is perfect as it is, the fact that you have over a million subscribers should be evidence of that. Fancy graphics, music, etc. is what channels tend to use when content is lacking (with exceptions, ofc). You're the opposite, your brain is constantly generating quality content, no need for superfluous crap that just gets in the way and dumbs it all down. PS: I miss those X-Wing intros 😅

    Scott, have you done any videos about drag reduction? I have wondered about a spinning rocket myself, like a rifle bullet rather than a musket ball. Alternatively a surface which carries an electrostatic charge may also trap a thin layer of air, to act as a lubricant. Maybe golf-ball dimples as well. Would any of those ideas work, or do you know of others? Obviously spinning may make life awkward for steering and navigation systems, but it may still be possible. Thanks.

    Why do we re-enter the atmosphere from space in the manner we do? Ie why enter at stupid speeds and travel laterally through the atmosphere causing the heating burn etc. Why don't vehicles slow down in space so they literally come straight down into the atmosphere hereby needing only a little power to stop them accelerating too much due to gravity etc and then use parachutes to finish the descent? Would landing like this avoid the heating burn since you aren't barrelling through the atmosphere like Wille Coyote on an acme rocket ;~)

  • Kepler


    17 dager siden

    Though this would avoid a lot of the re-entry heating you would have to slow yourself down from orbital velocity, taking almost as much delta v as it took for you to get up there. It's far easier for vehicles to let the atmosphere do all the slowing down for you than to double your fuel capacity

  • Rupert Reynolds

    Scot Manley have you covered how the Dzhanibekov Effect may apply to artificial 'gravity' in spinning spacecraft, such as 2 modules tethered by cables? Is it simply a matter of ensuring that the intended spin (end-for-endl) is the most stable one? Could be nasty if we got our sums wrong...

    Scott, this works BECAUSE you don't have a producer and a team of graphics-builders and research assistants. If all that happened, you'd be subject to commercial pressures of your advertisers, and they would want it all dumbing-down for a larger mass audience, and the script writers would insist you repeat everything three times, and the producer would want to add dramatic music "to make it more interesting" and it would be just another crap superficial TV channel. Please don't let that happen.

    Asteroid mining seems much more beneficial for end products to be used in space / on the moon. If you can process it end to end in space you can avoid the costs associated with earths gravity well. Although if we're making rocket fuel mostly from solar I guess that cost is not such a big deal.

    quite often, they change things because they cam, but that doesn't add value. Don't waste the effort on changing unless it adds value to what you have to offer. Like your said, you kinda like being scrappy, and for now, it may be what keeps you motivated. If you ever lost your scrappy edge, you might loose your motive? Well, maybe, depending on your situation. But, your motive is what your viewers can connect with, that similar passion for humanity's trek beyond the gravity well. Stay true to your inspiration, you're viewers will follow you, scrappy or not ;) upvoting @MaxQmodels about ad revenue...

    Le Verrier couldn't get anyone in France to take his calculation for the position of Neptune seriously, so he send a letter to an observatory in Berlin. They already had recent observations from that region and found Neptune moving in their records on the same day. So they did see it several times, they just had not noticed that it was moving.
