These people don't know what they are looking at or what they are doing...>> <<@IJ72 says : Everything for Musk! If you don't know, he is doing that to take us to the Mars and save us! When time comes, I will say to Must about this video! No Mars for you! Don't you even eat candy bar Mars! No Mars!>> <<@KenMac-ui2vb says : Almost there... just a little more Tax Payer Funds.>> <<@jsmeghead says : Oh come on. Your so butt hurt by his success. He's made more progress on this then most in the same field. No one will take you seriously anymore. Such a looser>> <<@SafirSecerovic says : I see zero evidence of manned moon landing here. Even less so, and waaaay less believable that it happened almost 60 years ago...>> <<@jesterzubrata says : This make me realize how fake moon landing is with shit technology 70 year ago we can go there and now with better tech we have a hardtime we can only go around earth so far😅>> <<@redbarchetta8782 says : ELON, another four letter word IMHO.>> <<@veganbutcherhackepeter says : Somebody needs to make a comedy show about three multibillionaires crammed into a tiny spacecraft going to Mars. I'm looking at you, Netflix.>> <<@infidelcastro5129 says : You can actually see him making stuff up as he says it. He’s so full of shit.>> <<@songbreaze says : Sick model collection dude seriously>> <<@doggedout says : I am 62 years old. I watched men walk on the moon as a child. Watching this tax payer funded cartoon nightmare is nearly breaking me. Watching actual people cheer on this incredibly stupid vanity project slow motion train wreck has broken my suspension of disbelief. It makes me wonder if I am real...or living in an incredibly bad simulation.>> <<@britishbulldog8966 says : It’s not nice to mock other religions.>> <<@victorbar3567 says : Valid point... Elon's time, the guy is always overly optimistic. The rest of your video and criticism... just plain shit, same as 99% of comments here>> <<@tonyprice1526 says : I was in technology sales. Our US business colleagues would over claim on market size, over claim on sales projections, over claim on technology, and then demand the bulk of financial resources to the detriment to efforts elsewhere. Musk is doing the same. He is a salesman who is brilliant at it. However he is flawed due to his tendency to over stretch the technology capabilities. He always moves the goal and continually ices the cake to make it look bigger and better. He will in part deliver on some things but ultimately he will fail on the stretched targets. He will blame others and walk away>> <<@andrewbyronloveshire5209 says : to be fair - i love throwing shade on uncle Elon, he's quite the fraud - BUT to be fair to SpaceX... they do have functioning rockets sending satelites into orbit all the time, its only the new supersized starships that are trialing new tech that are failing>> <<@geofromnj7377 says : Don't be surprised if Musk soon states publicly that the Apollo program was a hoax, no astronauts ever actually left earth orbit, and the black and white images of astronauts walking on the moon were filmed in a studio at some unknown location. It's for reason that Space X has not yet succeeded in executing a moon landing. After all, landing on the moon and bringing astronauts back to earth is hard. In fact, it's actually harder that producing the cybertruck in large numbers.>> <<@senormojo says : Hahaha! 05:40: A Rapid Unscheduled Disassembly! That is the best/worst spin on a rocket exploding I've ever heard. Oh my! 😆 An exciting end to the boosters' journey! You can't make that stuff up! Oh wait! They did.>> <<@greggavagan says : Why don't nasa get saturn 5 out of the museum and re-use the system that allegedly went to the moon 6 times. I think thunderf00t and destin from smarter everyday proved that nasa may not of gone to the moon with the boosted video.>> <<@jameshakola3603 says : 3:09 DUDE! Nice God Phoenix there on the left! Lots of great stuff actually...>> <<@kookiespace says : I thought we'd learned from the soviet lunar program that having too many engines on a stage is a game of diminishing returns because there's too many parts and too much complexity to make it work. The soviets learned that 50 fucking years ago. But I guess Elon doesn't like reading about history>> <<@batipapo says : They should fill up the next Musk’s rocket $1 bills to show us all how what’s happening to our tax $$$ 🧐>> <<@donwald3436 says : Ask FElon "when" the answer is always this time next year..... which year? "this" year! lol>> <<@antongromek4180 says : You just don't get it. This is not a simple rocket start - it's also a big bang simulation.>> <<@goofycker says : 9:10 A way to recognize Elon lying: stuttering...>> <<@jimjones-pz1tt says : It's fitting that the Starshit launches from a stool.>> <<@jarivuorinen3878 says : Not to defend the space X orbital test here, but 30 km/h difference is large amount of energy in speeds like 27000 km/h. Kinetic energy works exponentially, as Phil of course knows. But on the other hand, tumbling spacecraft will create more airdrag, so this difference is not meaningful. And we don't know about tolerances of their equipment either, I just assume that they have to be quite accurate for speed and acceleration as they got even this far, and these are not very hard things to measure anyway. Although I'm not sure what is the reference point to the speed of this re-entry tumbling spacecraft. From one perspective, reference to Earth surface would tell more about the kinetic energy changes. But from heatshield standpoint, reference speed to air is what is important, and air density. However, potential energy here also is important. If altitude goes down, and potential energy as a result goes down as well, then total mechanical energy (kinetic and potential combined) in reference to Earth surface goes down. This energy of course is absorbed by the spacecraft and surrounding atmosphere. This is high school physics. But I find Phil's argument here a bit dull because altitude, and descend rate, here would be important information to know how much the spacecraft actually lost energy when re-entering the atmosphere. Speed alone doesn't tell us much, especially when we don't know what that speed is measured relative to. That wasn't his main point anyway, I understand that he simply meant to emphasize that spacecraft was out of control, and that is fact, and if you do re-entering like that, your spacecraft will overheat and landing is impossible. It can also create uncontrolled momentum and vibrations that tear the spacecraft apart. And overheated metals have reduced capability to hold their qualities, and will oxidize in the atmosphere, so surfaces will very literally burn off. Aside from this SpaceX flight test, burning off material in re-entry in controlled manner is actually quite useful. It can actually form protective gas around spacecraft and keep material surface temperatures down. Actually this is very old idea for re-entry crafts, and has been used and tested by major powers. Ablative shielding is useful.>> <<@thebutthurtdesk4048 says : At this point I'm convinced that spaceX is just filled with first year engineer students doing some for fun project but with the backing of a national budget.>> <<@jessh2147 says : So SpaceX is just basically playing Kerbal irl>> <<@danielwesterlund1905 says : This moron can't even make good cars, but he'll definitely revolutionize space travel.>> <<@ang5035 says : Stop hyping mediocre white men!>> <<@guyonearth says : These SpaceX launch videos have a definite cult meeting vibe going on.>> <<@RocketPal says : What fail? Nothing but successes for now. Another fake update channel trying to push opinions, propaganda and BS. Go watch NSF, Lab Padre, Marcus House, Terran Space Academy.>> <<@utoob7361 says : NASA needs to be terminated>> <<@utoob7361 says : Elon knows more about getting his snout into the government trough than anyone now alive on earth. NASA is a giant waste of money anyway. Expect to see Elon go to prison for every kind of fraud possible. Either that, or he builds a Bezos-style yacht and never sets foot on land again.>> <<@ladymorwendaebrethil-feani4031 says : This is the result of the privatisation of the space exploration.>> <<@user-cx4ll4rj1t says : The current world's richest man is obviously the world's biggest bullsh*ter - surely he needs to be investigated and arrested. Even his character makes him unlikable so why do people laugh and smile at his every word --- sad people I guess. The same is true with the people putin surrounds himself with.>> <<@cmaxnat says : Ociangate upwords 😂>> <<@ch4rl3magn38 says : I love thunderfoot when he makes snake oil salesman look like they actually are>> <<@purpleaki7135 says : 23:53 says it all.>> <<@androidemulator6952 says : @26:18 "2018 Spacex CEo ( Gwynne Shotwell) .. hmm, unfortunate surname, given the SHOTS are NOT going WELL.. LOL>> <<@androidemulator6952 says : "Cheering like brain-washed Cult members." FFS ;)>> <<@SpaceBound-1 says : When you think about what people would do if they had the technology of the present. Well.>> <<@ripley_hicks_newt_86 says : Zero G games and restaurants. Yeah right!>> <<@Goddot says : They're making the N1 look good>> <<@BarrySW19 says : Has he thought about trying an electric rocket?>> <<@mikerash-pc4jc says : I saw Apollo take off and land as a young teenager. So my 45 years in manufacturing, electronics and electrical will properly build the entire rocket with the correct materials. Musk said he knows more about manufacturing than anyone alive. Well he doesn’t know me. Now Elon you’re screwed!>> <<@mikerash-pc4jc says : Ill will give SpaceX a working design for only 1 billion dollar. How will they guarantee the first flight works or I’ll give the billion dollars back?>> <<@mikerash-pc4jc says : Well to all my fans and friends from my post starship wouldn’t make it. How do you feel me now?>> <<@thelonercoder5816 says : why is this guy so obsessed with elon. You've been covering his entire existence for the past 7+ years.>>
