Which SpaceX milestone are you most excited for in 2019? Video corrections: 1) At 2:50, I provide the measurements of the entire Falcon 9 rocket at liftoff, which is misleading. Only the first stage of the rocket returns for landing, which is approximately 43 meters tall and weighs around 22,000 kg empty. 2) At 5:00, I state that the improvement in landing accuracy from 10 km to 10 m is 10,000%. This is incorrect. The increase in landing accuracy is actually a 99.9% improvement.
Dude, you can't write it like that, there's not 6 minutes' worth of fluff to read before part 1, and step 2 is simplified way too far. You have to spend 5 minutes explaining how you solve the problem and then have to find a pencil to slowly etch a small portion of the graphite into a circular pattern that corresponds to both the correct answer and the originally allocated number for the problem in the exam.
I remember watching the live stream of the first landing and crying tears of pure joy as humanity stepped into a new era. still get goose bumps and sweaty eyes when I see those scenes. ah, nice :) I liked this video, thank you!
I will never get over the ridiculous complexity of the engineering required to pull these landings off. I watch these landings in awe and amazement, it never gets old!
@@111utoobmetoob111 its amazing how many times he's watched the landing and still didn't figure out that its fake, just look at it, they cut to the smoke after, looked like the take off in reverse...so funny
Highly recommend that anyone who is really interested in how SpaceX does this, that they read the rather lengthy but greatly informative comment by David Ogawa. Thank you sir.
I watched this launch and landing with my family from Cocoa Beach near the Wakulla - it was fantastic! Having grown up with regular Apollo launches, followed years later by the Space Shuttle, this event marked a welcome next generation of US space flight from KSC. In addition, since the launch engines are so much more efficient (and quieter) now, the sonic booms of the booster landing are a visceral reminder of the older launches.
@@Angry.General1461 That's what the "re-entry burn" is for(duh), things only burn up during re-entry if they're going very fast, and the re-entry burn slows down the rocket to prevent that.
@@WhyPee24 I dont think we needed the (duh) but the rest of your explanation was informative cheers :o) I was hoping to see your knowledgeable response to The Angry General when asking about exploding fuel, is the slow re-entry not at all hot then?
Thanks, I was wondering how its done. For years I repaired an inertial nav system for the Air Force and others. I think the addition of gps makes a big difference. Grid fins also.
After landing on the drone platform, how do they secure the first stage for transportation ? The sea can be very quick to change. I watched Mercury as a child, this program has reignited my interest. Truly awe inspiring.
A robot, officially named the Falcon 9 Securing Robot, but universally known as Octagrabber lives on the droneship and is deployed shortly after a booster landing. The robot is remotely driven from it's blast-proof shelter and positioned underneath the Falcon 9. Four arms then raise up and latch onto the Falcon 9 Octaweb, securing the booster.
@@SniperMro1 Not every 10 mins videos do that. The goal for 10 mins is to get more ads In video. And this video has no ads on it. And Elon musk fan is correct The current format is less blatant
You know, people are always caught up with ridiculous specs and this incessive need to prove they know better. I really enjoyed the video for the information and how you delivered it. Thanks for the great work! If others think they can do better, let them actually prove it!
@@ReneAltena The title of the video was clearly answered as recognised by myself and dozens of other commenters. You may have to watch the video a few timesb but is all there just not wrapped up in a simple little package like probably wanted. Gosh and whoever thought rocket science wasn't simple?!

I just love the space X command center. All skilled people giving their best on computers inside glass room and all fans just jumping with joy outside the glass room
Make sure to remember that there are suicide burns. This can be much better completed through more accurate computers that can run the staging sequence perfectly. This might have also played a role in their "10,000%" success rate boost. Next time, give us the math as well. I am quite curious how the suicide burn works, but I am unsure of how to calculate it completely.
You need to calculate the deceleration that will be applied, taking into account the reduction of mass as propellant is depleted, such that velocity reaches zero at zero altitude. Also, as you might be aware (but I will mention it anyway as others might appreciate it), doing suicide burns is not only a propellant saving technique but is actually necessary as the engines (or engine - singular) cannot throttle down low enough that it won't begin to ascend again if you accidentally reach zero velocity before reaching zero altitude (landing).
@@thepieoneers4421 as this video delivers merely any real Information about any background... consider checking out Scott Manley (esp. for space-math-things) or Everyday Astronaut
Your description was the most thorough and accurate description of any SpaceX process I have seen to date, and I've watched them all, some multiple times. Adding you to my bookmark, please keep it up. And feel free to use my comments. Thanks.
Excelent video, dont pay mutch atetion to hate comments, for people who 1st come to know about SpaceX it is very usefull information, the people who dont liek dont care about thye time it took you to gather all that info and video footage, well done, i just give the tip they gave me give a little more pause to your talking dont mind if the video is a little longer
After watching a nasal documentary about the shuttle, it almost feels embarrassing for them not to have led this over spacex. That said, space flight & exploration amazes me, more so that the Astronauts were around my age, people working on it for nasal even younger, puts my achievements into perspective. What a great 80 years from the dreaded V2 bomb leading to the falcon 9.
Grid Fins are also the control system used in MOAB(Mother Of All Bombs) They are high Lifting devices often used as alternate to wings Has so many variants based on orientation of panels ,the number of panels, the depth of fin, etc. Straight forward to design and analyze but hard to optimize on Panel level...
it's common practice to use SI units in anything to do with science, it's just not often used in daily life (though medicine is a good exemption, as it's usually by per mG or per mL) even NASA uses SI, there just so happens to be a law that makes NASA legally requires to make any public releases use the imperial system (though I believe this is a cold war era law)
You forgot 1 key thing: AI & big data computing for precise autopiloting the rocket. During years of their r&d, they collect huge amounts of behavioral data of the whole flight path / rocket positions, engines & thrusters. So the AI computer really learns from previous mistakes. The AI system became very precise & proficient in controlling the vertical descents. Thus SpaceX's success. This is they key factor.
As a kid watching black and white tv in 1969 for the moon landing, the kid in me gets goosebumps watching the landing of rockets in the ocean! Elon sometimes seems a little kooky but man when he he on he is awesome! Best of luck to the next generation of explorers!

@@michaelmulder1289 Just fucking with you dude, I'm just giving praise to the people that made this technology work. Whether it be made in the USA, by millennials, or snowflakes....it's still impressive.
The crazy part is that 4 years ago 30 successful landings and 17 re flights in total was groundbreaking, while SpaceX today is on a steak of 167 successful landings in a row (240 in total) with multiple launches per week and a single booster launched up to 18 times.
I think it's awesome when it returns to earth to land -love it!👍🙂.Quite funny really , when I was at school in 70s , I use to draw the same rocket taking off then landing somewhere else , as is , so i knew all this was going to happen then, at 12 👍😊.Nice to see what I knew , came to be 😉🍻
The landing accuracy has been very reliable. I wonder whether they could do away with the deployable landing legs altogether by landing in a cradle or capture system of some sort. That would save weight, simplify the design (of the rocket), reduce drag and reduce the risk of deployment failure leading to damage.
Takes me back to watching Thunderbirds But would i trust a computer to bring me down that has thousands of working parts not sure but i have a lot of admiration for the scientist and engineers who put this package together?

I watched Mercury as a child, this program has reignited my interest. Truly awe inspiring.
They refilled the fuel and fly back to the land base. Maybe
They have an "Octograbber" robot on board the drone ships that comes out once it is safe, and it clamps the base of the booster.
@@CPlater1 Thanks. I didn't know about it. It would be dangerous under strong wind attack. Of course, they will choose a right time to do it.

That would save weight, simplify the design (of the rocket), reduce drag and reduce the risk of deployment failure leading to damage.
They are trying to catch the fairings in giant nets to be able to reuse those. I'm not sure if they have done it yet though.
Takes me back to watching Thunderbirds But would i trust a computer to bring me down that has thousands of working parts not sure but i have a lot of admiration for the scientist and engineers who put this package together?
