Beautiful,smart,handsome man-my respect

Wow

Bro just casually assembling a lunar lander, and I am just here nodding my head like I totally understand

SpaceX, has success due to its rapid manufacturing of test rockets and therefore the many progressive test leading to succeeding where other fear to go, etc 😂

Not a rocket scientist here... just a trucker. So please be kind 😅 Given that Starship is the truly revolutionary part of the Starship/Super Heavy combination, and it seems like they've got the design for the booster pretty well dialed in, it would seem to make sense to have some kind of non-reuseable second stage to put on top of Super Heavy. Essentially, BFR. That way, they could start making use of all that lifting capacity while waiting for Ship to be ready.

I can see a viral demand for Mooncoin.

Your point about telepresence is well made. And from a technical perspective, it is correct, but it ignores the core of the issue: which is budgets and politics. (Never make the mistake of thinking that the technical facts and figures are the core of the issue... they basically never are for ANY issue. This is because, with enough money, one can generally overcome near any technical issue, and the gate-keeping of large amounts of money is always political). There are three Political Space Factions in America. Here they are named after their first or principal proponents. The Von Browns see Space as all about international relations and grand spectacles. The Sagans see space as all about Science. The O'Neills see it as all about Settlements (full disclosure, I'm an O'Neill). Apollo and Skylab era NASA endeavors were mostly about the Von Brown Agenda... they didn't want telepresence robots on the moon for the same reason they didn't want cheap and routine space flight... it would eliminate the POINT which is spectacle for international diplomacy reasons. Telepresence robots on the moon are much less of a spectacle than people. In the early space shuttle era, the Sagans weren't interested in telepresence on the moon because there was more and cheaper science that could be done with floating space telescopes like Hubble or robotic probes that were sent too far for telepresence to work. The O'Neills have, until relatively recently not been afforded any power in NASA, and even now entities like SpaceX attract their attention more. That's why it hasn't happened. Concerning you're brief asside about radiation exposure on the Lunar and Martian surfaces... not really sure why you think that matters much. Neither environment has much on the surface that matters. Settlements will be sub-surface and most maintenance in either location will be performed by telepresence robots operated by humans in the same location. There's a 1 second delay between the Moon and Earth without delays built into the telepresence robot and communication network. That much latency, as anybody who has ever played an online multiplayer video game knows, is almost crippling. You CAN do it from Earth to the moon, but you can do it BETTER from Moon to Moon. Your radiation position makes more sense when considering spinning habitats that are not on the surface of natural bodies... which lets face it are going to be where most humans end up living. But even then, there will be enough shielding, both material shielding mined from asteroids, and EM fields that the unprotected radiation number for space, either inside or outside the magnetosphere of a natural body only relevant to a "What if something goes wrong?" contingency plan. Your points on Falcon Heavy are well taken... and to me it comes down to Farring size. Why has SpaceX and NASA been so reluctant to develop a WIDER farring?

should use Chain on Arms instead of Long Rails for catching booster - chain could self center - can wrap around booster some - -can use several catch hooks - will catch on chain links and not Slide - fast adjust - tighten Less chance of smashing booster - form arms/ chain n slight U shape Bowed - Strong - could also use a Cable with stops added on cable - Rail catch looks sketchy to me

The angry astronaut we neeeded

Great ideas! Fear not, I think Elon's dream of lowering the cost space flight will open up all these possibilities.

For the lunar lander, why don't we consider the SkyCrane architecture from the Mars missions. If scaled up, it could be reusable after dropping it's cargo. What would the mass and fuel numbers be for that?

I’ve been thinking for some time now, and hope that it’s a viable idea, that we could perhaps develop a 100% reusable spacecraft that’s potentially even larger than starship super heavy, uses turbine jet engines on 1st stage, mix of turbine jet and SCRAM engines (or whatever the upcoming state of the art hypersonic jet engines are) for 2nd stage, and for the 3rd (or however many stages this method winds up taking) stage, you would then use either whatever Vac optimized chemical engine u want to use, or depending on the circumstances you could implement several large Hall effect thrusters, VASIMER (sp*), fission, fusion, solar sail, Warp drive…(obvious joke) or even a combination of the above engines. It would seem that these 1st and 2nd stages could be flown back to LZ w/ SO much less risk and cost as you wouldn’t have to pay for oxidizer. Also much more efficient as there’s no mass penalty for oxidizer. Plus these engines are inherently hella more efficient and need less upkeep than rocket engines and experience less stresses et al. Idk to me it just seems like an obvious next step although I’m just not convinced that jet engines scale up like rocket engines do. I’d be super interested to find out. I’d like to research this topic now…🤔

Would it make sense to add 2-3 additional boosters to Falcon Heavy?

Also, the lunar decent engine needed to throttle deeply. Can the aerospike do that? Might be easier to control several small engines. Also, 380 isp is close to the theoretical maximum for methalox. We will need to see that potential realized

As a Chinese I don't like your political views, but the scientific part is accurate. We have been operating under limited funding and Western sanctions and still we sticking to the time schedule. Chang'e 6 returned 1.9kg of samples from the far side of the moon.

I think your LOI dV numbers are a little low. More like 800dV to low lunar orbit plus at least 2000-2100 to land and take off from the moon (gravity losses).

Al Gore Rhythm!!!👍🏾

10% dry mass for a metalox rocket seems pretty high, this is usually a value for pure hidrolox rockets, but in this case you have higher deltaV, if you re-make the calculations with 5% dry mass everything will look better.

We need to stop screwing around and get back to the moon. I think we need lots of machines, but a few humans too. I just turned 50 and I"m ready to go. Not sure about the plan to use Falcon Heavies in expendable mode. Either we plan to use the starship, or send up modules in heavies with 2 or more launches. It's not like the 60's where we aren't sure we can rendezvous and dock in orbit. So what if we send up a CM and lander on separate launches. Plus as it stands now the Heavy isn't human rated either. Praying we stop screwing around and get he Starship on the moon soon and then hopefully we can get enough mass there to make a strong and quick foot hold. SO what is your take on seemingly small solar storms turning into large geomagnetic storms recently? Seems all out of whack to me. Might give us some other issues in space soon.

I really like how you edited this

White privilege must be great 👍

It is absolutely distressing that NASA didn't use robotics to start building human habitats on the moon. They could have tried a variety of approaches and learned from failures. What went wrong.

Getting cargo and rovers to the lunar surface is one thing. Getting humans there and back is a different story. Sure, use cryogenic propellant for cargo and landers, that's fine. If it's my ass on the line. I would like something more reliable, like hypergolic. As long as Boeing doesn't design the manifold, it should be good.

Always an interesting journey, thanks.

What is it that people are going to do on the moon? Going to the moon was awesome, but what is the value of going back?

10:10 an aerospike does absolutely diddly squat for you in vacuum (such as when trying to hover/land on the Moon). The beauty of aerospikes is that they form an optimal expansion envelope during _atmospheric_ flight, as external pressure goes through the full range - so you don't have to separately equip sea-level and vacuum-optimized nozzles. An aerospike is a good 'universal' solution, that does well in all regimes - but as so often happens, a Jack of all trades is a master of none. In vacuum, a good vacuum-optimized bell nozzle will beat the tar out of an aerospike, in terms of overall efficiency.

I heard recently that SpaceX is approved with decommissioning the ISS, but with the way things are with Boeing I’m not too sure of that anymore…

You my friend, need to collaborate with the angry astronaut to bring about the real engineering enigmas that if we are to accomplish the moon, will need critical analysis and engineering sciences to overcome gravity.

A no BS channel. How refreshing. Subbed.

It will test Lunor Starship will tranfer equipment to moon, or Space X need redesgn it.

Frist Lunor Starship, should be Cargo vrsion, caring lunor robot setup becan [help next lunor starship landing], Constrution [level Landing site],, and setup power/ comunicatio .

I love the motto: "This IS Rocket Science."

CSI Starbase is THE starship channel. Nobody comes even close to close.

Well one thing Russia did was fly our boys and girls to the ISS for a decade after the shuttle finally fell apart. Keep it about rockets not your own political opinions please.

The worst aspect of the time we’ve lost in our space program as NASA sat on its hands for decades while continuing to waste taxpayer money and cash paychecks is that we can NEVER recover that time. 😢

To protect people, you really want a space ship to be built like a battleship, with 12" of steel armor around the living quarters. Space is dirty, and the faster you go, the more volume you sweep through and the more high speed impacts you must endure.

It works with cartoons, India and China are poor quality, but they make it work. We used to make real good cartoons, space-x will get there, once they start using pastels.

ive always said we should be sending seniors , especially for long duration monotonous trips. Set up a bingo display , load up the geritol and they will do just fine. Not to mention theyre aquired wisdom is invaluable

We should not ignore the old Surveyor design. Equipped with up to date gear, this proven, reliable bus won't tip over. made of modern materials it would be ultra light.

Unmanned construction on the moon is unfeasible. Compared to manned missions, it is far more expensive and more likely to break. The issues with high development costs make it difficult, and the motivation for people to send robots is low compared to people.

Another great technical channel is Eager Space. Low sub count but lot of great insight (and dry engineering humor :).

Actuslly we can use the 9 meter booster, of Super Heavy, Starship add in a second stage to the moon orbit, and we can release a fully fueled lander and return launcher, to bring back the samples. We can build a massive faring, and send a 50 tons payload to the Moon.

I agree we should at the very least be launching ROSV's (Remote Operated Space Vehicles) a lot more, specially with all the advanced systems we have now, we also should be looking more at hybrid 1st stage systems using turbine based engines supporting rocking engines to help reduce cost and increase reusability.

SpaceX was supposed to work on extended Falcon fairing but it's been a really long time since I have seen any news about it

Lets call the coins Actual Luna! Best marketing begines at crypto's expense.

I want a wide starship hls somthing around 15m wide and 25m tall

I really like the idea of making coins out of the regolith.

Yep. The US is going to let it happen. Science fiction writers will start using Chinese Mandarin instead of English. Mandarin will be the language of Luna.

Military is a waste of money in the grand sheme of the universe. It does not get into my head why humanity, as one species, tries to kill each other as fast and cruel as we can. NASA and every other space agency around the world is heavily underfunded for greatness that we could have achieved by now as humanity. I hope it changes in the next 25 years for the benefit of space exploration. I want to be alive when we set foot on mars and other planets building colonies ...
