China's Moon Secret Revealed // Starship Success // The Real Asteroid Danger 

I agree!😊

Again. :-)

Perhaps they're not afraid to show their failures because that is now the 'norm'? Especially for sociopaths like Musk who doesn't feel he should have to care if things go wrong. How will he respond if/when people lose their lives when things go wrong. Will you praise him for it then?

Wadirum, locals know it as Wadi and themselves as Rum, hence a no brainer for the judges. ( Or has some Indian guy slipped half his name into cosmic canon )

Among those some well placed idiots will find a way to corruptly make a profit with the philosophy that "There will be enough of Earth Left to spend my money!"

We'd have to send The Rock to punch it

Some nations have been very aggressive and attacked another nation even now without the other drama

I would second that. And thank you for being a human, who understands his script! I get so sick of videos with robots reading scripts that ,of course, they do not understand and hence bungle in various ways.

I can´t really answer your questions, but I believe JWST is now always directed with its back towards the direction of travel, which should make a big difference.

Reaction wheels are now ceramic so they shouldn't fail the way they used to. Only new causes of failure from now on....

LOL😂😂😂😂😂

Uh huh? Is that sarcasm I’m detecting? Unless there is more than one China. LOL 😂

The booster went super nova 🙂

Definitely have some timing issues to work out with the stage separation.

@@oldschoolman1444 They may need to shut down the booster after stage separation then wait for the fuel tanks to stabilize before restarting. The booster is basically in a free fall. The reason they wanted to keep some of the engines running was for thrust to keep the fuel where it should be to feed the pumps. This was so the booster does not have to wait to do the boostback burn to return to “base” otherwise it keeps flying down range.

@@ronald3836it was absolutely beautiful in the early morning light, like a constantly flowering rose. Best launch I’ve ever seen

​@@oldmech619 : I'm thinking they should add a single massively smaller engine for their constant thrust, so they can maintain thrust with "almost no" fuel consumption. It should get them most of the benefits of keeping those three center engines on, with far easier engineering requirements.

How soon, can stretch out to happenstance, a lucky observation. Detection depends on what approach angle, chance of a telescope looking there and seeing anything unusual. Albedo of object, shape and orientation, obscured or overlooked, many things. Planet killer...what do you mean? A small Chicxulub range 100km Global mass extinction event crater, flip and melt most of the crustal rocks - erase all life, or larger? Oumuamua when found would have been 10 days warning, retrospective data if noticed 5 days more. It wasn't exactly shining or generating a comet tail to show up and was already heading outward from the sun. Estimated 100-1000 metres , plate-like, 50 kps, about 10,000 megatons impact, depending where it hit from disaster to catastrophic, not global extinction. The impact energy has a wide range wrt 'planet killer' depending on angle. The Earth orbits the sun at 30kps, a near headon impact of a smaller object has much greater energy and smaller means less warning time. Approximate detection a good chance of 500m 1 AU with 40 days lead time at 40 kps. For an interstellar object impact comparable to the Chicxulub impactor energy, 10 km diameter at 20 kps, 72,000,000 Megatons it has a high chance it could be spotted a year or two out, perhaps more. Or it could whip around from behind the sun and have a month or less warning. Practically no time to do anything, still maybe enough to deflect it a bit if prepared. Earth is a tiny target and very roughly 150 million to one that any random object that happens to pass through the inner solar system is going to be in the same place as Earth at the same time. Only need to shift the intersection a few thousand km or a few hundred seconds, possibly a lot less if it is only just going to touch by a few km. Of course touch = full impact energy delivered to planet. And you need pretty good instruments for tracking and prediction to be able to decide whether it will miss by a gnats whisker before everyone decides which doomsday movie they want to re-enact. I suspect just the media reaction knowing Oumuamua was going to hit in a couple of weeks would be more damaging than the damage when it hit. Odds are it is hitting in deep water, it isn't all that big really, sucks to be near the coast.

@@johncarlaw8633 Wow, that was a thorough answer. What I meant with planet killer was extinction of all life. I was thinking of a head on impact with the fastest possible relative speed. I assume interstellar objects have quite a bit more velocity than a common asteroid (and asteroids orbit the Sun in the same direction as the Earth so a perfect head on collision will never happen) so the impact energy would be equally massive.

they rare enough chance of hitting extremely low. But your right they traviling way faster. Rogue Planets, Brown Dwarf or Black holes are also possible but chances of all so small it not really worth worrying about. It the in system stuff that is way more likely to hit. @@arnelilleseter4755

@@arnelilleseter4755 would most likely hit water, and cause tsuanamis near the countries that it hit. Would not have been fun. Which is why we should start getting serious in a defense/monitoring system in the next 50 years or so.

The other solution is to slow down enough in orbit so that entering an atmosphere will not generate the amount of heat that requires shielding. Either way a large amount of energy will be required. Neither is practical until nuclear powered spacecraft become common.

🤣🤣🤣🤣🤣

Unlikely, the orbiter had a problem with oxygen containment, its likely that one of the turbines malfunctioned, or the seal lost containment. This is a mechanical QC issie.

There would be plenty of volunteers.

Cue the Star Trek theme.

Forget it. Our 8 planets are not even 1% of the mass in our solar system. Again the asteroid belt is only about 2% the mass of a single planet. Examine the reason why dark matter was postulated: this would in reality throw the stars out their orbits and no galaxy could exist. Face it, they dont get the three-body-problem. Now the three-trillion-body problem laughs at them. It really came in handy, that StarWars got popular at the time. Beware the dark side. 🚀🏴‍☠️🎸

Exoplanets don't contribute any noteworthy amount of mass to the total mass of the universe. Most of the mass is contributed by interstellar and intergalactic gas and dust

I heard that if any type of unplanned event occurs (if things do not go as planned) the rocketry is made to explode high in the sky to reduce damage on ground. It had problems so self destructed.

@@MARILYNANDERSON88 yes, in the videos it looks like a couple boosters went out after recognition and one or two blew.

It needs to compensate and adjust for the earth's spin

Also it may have gone up at a bit of an angle to be over the launch pad for less time. If it were to fail in the early portion of flight and crash back down better to move it away as the destruction of the pad would be very bad for the programme.

I think about this spiral effect on rocketry and examine foxtail plants drilling mechanism, as above so below.

Canada/USA has a huge land mass too.😮

@@NovaDeb the US has too many populated cities and towns. Canada is fairly remote up north. And russia has a ton of free land where an impact would probably not have extreme consequences to people and buildings

Nope no relation.

Sure they managed not to fail the launchpad witch was last time, let's not forget it, a first in space industry! The hot staging worked magnificently, unless it caused the first stage to blow up beautifully. And the top part blew way higher than last time, so much closer to Mars. At least it's RU-vid rated.

@@cgourin That was edited ? ? WTF, edited to sound like a 4th grader wrote it ?

@@uuzd4s Yes, you caught me: I forgot the space after the beginning of a sentence and the dot was interpreted by YT as an URL witch is bad for security reasons to complicated to explain even to an acute 5th grader like you.

@@cgourin Witch ? Still high from Halloween ?

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CTcSMh4VYow.html This is a good video showing issues with Starship spinning & rotating taken by telescope in the Florida Keys. Can see why the flight termination triggered as it just was not recovering.

I wish I had advanced knowledge. 😔

Hah, yeah, that.

😊

No, it cant turn it's heat shield away from the earth and sun .

Falcon Heavy uses 27+1, never had a failure.

Finer thrust control and additional redundancy seem to outweigh the added complexity.

Yes, 6 to 7 years is a reasonable time for developeing a rocket, if the developement bases on an intelligent plan. 🚀🏴‍☠️🎸

@@MichaelWinter-ss6lx Given Falcon 9 has been routinely operating for a good few years new it's more like 3-4 years.
