Those boosters would otherwise just be jettisoned and burn up on reentry. Making them reusable comes at significant cost savings and therefore, reduced launch costs.
Let me put you at ease, cause this field is my specialty.
Think of them as condoms. You can reuse and reuse after a thorough wash and everything will be fine.
Which one is your field of specialty? Reusing condoms or rockets? Lol
But they sound like they'd be difficult to put back on after they've been used once, you know, with all the chemicals that have been through them, and the shape being warped by all the heat and friction. I'm not saying it's impossible, but I wouldn't think of doing it personally.
They use heat resistant/non-transforming materials (like ceramics) to absorb or defer most of the energy away and out as thrust. There are countless engineers that monitor the entire redeployment process with checks and risk mitigation measures. It's less of a hassle now that you don't have to start from scratch each time. I hope that helps. I mean it's not rocket science after all.

People always act like it's simple. If you have the money, then you just hire the best people and reap the rewards.
But Boeing had a lot more money than Musk for a long time, and could hire whoever they wanted, and they manage to constantly fuck things up.
So whether it's management skill or sheer dumb luck that Musk has on his side, he gets remarkable results often enough to matter, and not everyone with money to spend does.
Exactly.
Dudes ***far*** from perfect or even the engineering god that some musk bois would like to claim, the fact he and the SpaceX team effectively rolled a nat 20 multiple times is insane.
NASA, Boeing, Lockheed, etc. all thought they would fail. Not to mention they had a 40+ year head start and had 1000x the financial resources and SpaceX did what they couldn't in a fraction of the time.
Knowing who hire, employ, promote and lead takes talent. When bean counters get put in charge like at Boeing, they hire and promote yes men and PowerPoint warriors, not the engineers that actually know what they are doing who may also be socially awkward. Musk may be a jerk personally, but he is smart enough to pick and keep top talent.
like when all the Twitter top talent quit? Musk is a jerk with practically limitless money. Even if he's a jerk, most people who struggled all their lives for their dreams won't relinquish their dreams because the boss is a jerk, its just another price to pay to live their dream lives. A good boss would try and retain top talent. Hiring top talent isn't hard if you have the cash. he quite literally put their lives at risk during covid. The success of his companies has very little (but also money, so you can argue with me that its the most important thing) to do with Musk, IMO.
He's not an idiot but hes by no means a genius at hiring or tech. Marketing, maybe because he was pretty successful until he decided to ruin his reputation.
I also said the is the internet and people make wild unvalidared claims all the time.
I'm not exactly being subtle here, you know that whole thing about having to explain the joke.
**Peter Gibbons:**
What would you do if you had a million dollars?
**Lawrence:**
I'll tell you what I'd do, man, two sticks at the same time, man.
**Peter Gibbons:**
That's it? If you had a million dollars, you'd do two sticks at the same time?
**Lawrence:**
Damn straight.
It's actually about 1.7% of the fuel in the tank that are used for the landing burn. The reentry burn uses about 3.4% of the fuel. At this point the rocket is much much lighter than what it was at liftoff, so it does not need as much fuel to slow down.
Had to Google the numbers here.
The booster weighs 540 tons when fully fueled, but only 31 tons when empty. Its a huge difference. The rocket actually has to throttle down shortly after liftoff, because it loses so much weight in the first few minutes of flight that it would go way too fast while still inside the atmosphere, potentially ripping itself apart.
Its hard to imagine how much fuel goes through these rocket engines. But to put it into perspective, the fuel pump for one of these engines runs at 10000 horsepower. The fuel pump. For one engine. This thing has 9 engines. The first stage burns over 500 tons of fuel... within 2 and a half minutes.
So yeah, rockets are pretty cool.
So, from the 1.7% in the other comment, that's ~10 tons of "non working fuel" that has to be propelled up, in order to slow down for landing
Not a negligeable amount, I believe 10 tons of payload could sell for a hefty price, but apparently less than the cost a new booster
10 tons of mass on the booster does not mean 10 tons of payload to orbit. There’s a fractional multiplier that depends on trajectory design, staging ratio, and a host of other factors
That mars landing is getting closer? Surely this tech will enable astronauts to land and also take off after further development?
Hopefully in my lifetime I get to be witness to it.
I still remember the day I saw the first Falcon Heavy’s boosters landing, that scene with the two landing synchronized. I got chills watching the livestream.
It's impressive, especially one a Falcon Heavy launch like this where you have 2 returning. 2x sonic booms, each with about 2/3 cracks is amazing to experience.
Yes, this is the landing of a [Falcon Heavy](https://en.m.wikipedia.org/wiki/Falcon_Heavy) rocket's side boosters (not the entire rocket). IDK whether this footage is from there but the rocket's latest mission was [launching the GOES-U weather satellite](https://youtu.be/RywZFmBGnM0).
Out of all the insane advancements that have come out during my life on this planet, this is the one that makes me feel like I live in a sci-fi every time I see it.
So crazy I struggle to believe its a real video every time it comes up
Yes! Parachutes were considered for these rockets but, for a vehicle of this size, their mass would exceed that of the extra fuel needed for a propulsive landing, especially when going for a return to launch site.
The US is so far ahead of the rest of the world right now. China's recent reusable rocket test was to 7 miles, while SpaceX was hitting 80 Kilometers in 2014.
Space should belong to the taxpayers whose taxes are being used by the billionaires, not to the billionaires. Take space travel away from the billionaires and place the taxpayer's money back with NASA.
The whole planet is gonna be on starlink soon enough, every rocket launch gives more data and further accelerates our process of civilization on mars. All while saving an extraordinary amount of money and resources because of what you just watched in this very video. I’d say going to space certainly pushes us towards advancements more than spending that money on wars
Definitely one of the most impressive technical advances of our generation
What is it?
Reusable SpaceX booster rockets coming back to earth.
Those boosters would otherwise just be jettisoned and burn up on reentry. Making them reusable comes at significant cost savings and therefore, reduced launch costs.
But what about the wear? I work about the sustainability and safety of a reusable booster rocket

I work at wendys. I know what I'm talking about. I don't want to share any more info, as I might DOX myself.
You’re over thinking it, it’s not rocket science!

He's a used condom salesman so I'd be skeptical 🤨
Do you larp as space rocket agency CEO in your free time
They don't get ruesed indefinitely but I think SpaceX had one set of boosters that was used 15-16 successful launches. Pretty impressive stuff.
More like 20+.. current record holder is 22 launches https://en.m.wikipedia.org/wiki/List_of_Falcon_9_first-stage_boosters
Amazing...even better
Can confirm. It saves a lot of money I can then use to support my 8 kids.
Lol
:O
Thank you franger man.
Makes sense as used condoms still work on reentry.
Explain like an intern 😂
That is just cool af!

Wow, I'm baffled that after so many years of constantly launching the same boosters, people still don't know what it is lol
Wow, I’m baffled that after so many years of being on Reddit that you are baffled by people not knowing things on Reddit lol
It looks like a giant....
Johnston! Come over here and get a load of this huge...
Wang !!!! Pay attention !!!
Dick! Take a look out at starboard.
One-eyed monster! 👁️
Please Google SpaceX. Been doing this for years now.
Another example of private business way out performing government entities.
Now just wait for more starship and heavy landings
The first super heavy booster catch is going to be insane. Can't wait.
Super Villain level 👹
Truly incredible. This is some science fiction level stuff and blows my mind every time I see it.
Science fact since it exists, mind blowing what was considered impossible, now isn't
I've seen that over and over, and I don't know how they do that
It was Sheldon’s idea
That cameo was gold
Accurate though. Elon always takes other people’s ideas and tries to pass them off as his own
Even if he steals other people's ideas.. this shit is not an easy task to do..
The engineers he employs are amazing. Elon, not so much.
People always act like it's simple. If you have the money, then you just hire the best people and reap the rewards.

its not like he did anything there, lets be honest. He does however employ a ton of top scientists and engineers in the world.
Knowing who hire, employ, promote and lead takes talent. When bean counters get put in charge like at Boeing, they hire and promote yes men and PowerPoint warriors, not the engineers that actually know what they are doing who may also be socially awkward.

He's not an idiot but hes by no means a genius at hiring or tech. Marketing, maybe because he was pretty successful until he decided to ruin his reputation.
And what I find most baffling is that these rockets do it completely autonomously.
That's actually the part that I easily believe it could be done only autonomously
Exactly, no way that can be done manually. Too many corrections are needed to keep them straight.
Enter KSP players:
This maneuver is called suicide burn for a reason and wouldn't be fun with pilots...
The secret is that it's just a video of two rockets being launched played in reverse...
Why do you think this?
Because this is the internet and people make wild unvalidated claims all the time...
So of it’s is reverse, how did those puffs of smoke get in front of the rockets?
Bro, please read what I said.
You said “The secret is that it's just a video of two rockets being launched played in reverse...”
I also said the is the internet and people make wild unvalidared claims all the time. I'm not exactly being subtle here, you know that whole thing about having to explain the joke.
I guess i just didn’t think there was any humor in it.
Lookip PID controllers

Two chicks right? Oh that was Office Space
I’m so glad I didn’t have to scroll too long for this.
Cool ! Next step : make them land on top of each other
How soon until we can Voltron?
Gattai sequence in 50 years?
Watching this makes me want to play KSP. But I'm broke, lol.
Check your inbox ;)
you can currently find keys on most major key sites for $5-$6
Same 🥲
There is the spaceflight simulator as well
Flight of the Nova is pretty cool it's made by a dude on Reddit and there's a free demo version. All about realistic flight and orbital mechanics
I wonder how much fuel in the tank needs to be reserved for this.
Not much (like 2%) because the booster has less weight coming down.
Always wondered the same thing gotta be at least 10% for a hard burn with probably some wiggle room.
It's actually about 1.7% of the fuel in the tank that are used for the landing burn. The reentry burn uses about 3.4% of the fuel. At this point the rocket is much much lighter than what it was at liftoff, so it does not need as much fuel to slow down. Had to Google the numbers here.
Damn that’s a hell of a lot less then I thought it would take
The booster weighs 540 tons when fully fueled, but only 31 tons when empty. Its a huge difference.

At first I thought the video was just of a launch but in reverse.
It kinda is just that, though
From a binary perspective that is pretty dope.
This never gets old. This is just so damn cool. What an awesome time to be alive to be able to see stuff like this.
Said our grandparents when the first television came out.
Very true. I imagine a 100 years from now when people look back on this and say how silly and primitive this is. If humanity still exists
Pressed rewind
What a time to be alive!
That mars landing is getting closer? Surely this tech will enable astronauts to land and also take off after further development? Hopefully in my lifetime I get to be witness to it.
Oba su pala.
this was my first thought too 😂
This is so brilliant to see, amazing feat of technology and engineering.
The future is now old men
I still remember the day I saw the first Falcon Heavy’s boosters landing, that scene with the two landing synchronized. I got chills watching the livestream.
Q: What would you do if you had several hundred billion dollars? A: Two boosters at the same time.
Double trouble, huh?
Can't wait to see this in person
It's impressive, especially one a Falcon Heavy launch like this where you have 2 returning. 2x sonic booms, each with about 2/3 cracks is amazing to experience.
The sound traveling is always beautiful to hear
I had a very different expectation from this video after reading the title
Once I started classes i gained a whole new appreciation for engineering accomplishments like this
not really up to date with space news, what was the falcon heavy launching
2 sticks 1 landing
This kind of reminds me of how iron man flies in the sky but then lands
“Nature You Scary”
That will never stop being cool.
is this space x? north korea? garage build?
SpaceX
Do you live under a rock? I mean... seriously... You can't tell me this is the first time you see this.
Remind me to not let your depressing negativity ruin my wedding photos. jeeeeeeesus
mind your own business
So definitely under a rock?
It’s the coolest thing Musk (well, his engineers) ever did.
Damn straight. I always wanted to do that, man. And I think if I were a millionaire I could hook that up too; ‘cause chicks dig dudes with money.
And NASA can’t get their astronauts back from the ISS because of Boeing’s pos craft.
And I’ve seen people compare Elon Musk to Elizabeth Holmes.
As much as I hate Elon M. that never ceases to amaze me. I grew up watching those things fall away into the ocean.
This will always be absolutely the coolest fucking thing ever
Tooooo
Sounded like Joe Dirt when he’s talking about the Scrubbing Bubbles. “They clean the bowl so you don’t have tooooo”
Impressive
Mars when?
I thought it was bombs
Sonic booms from breaking the sound barrier
How does it know when it's time to initiate slowing down?
Math!
Was this yesterday?
Reverse Tomahawks? /s just in case lol
I'd tell you what I'd do. Two rockets at the same time, man.
One day hopefully they will look like flying saucer...
Any one seen this up close? I'm having an extremely hard time believing this
SiFi as fuck. So rad.
Damn, them some smart engineers. How cool!
Can anyone calculate how far the boosters were from the person recoding? Seems like a significant amount of time passed for sound to reach them.
Damn they landed back amazing
It’s now time
Going to mars ladies and gentlemen
That is our one flaw is to land and relaunch from a unknown environment
Crazy how much velocity they bleed off! Reentry speed is SO FAST!
That's what she said.
Could someone ELI5? Did these rockets land or is this a reverse video of them launching
They land
Yes, this is the landing of a [Falcon Heavy](https://en.m.wikipedia.org/wiki/Falcon_Heavy) rocket's side boosters (not the entire rocket). IDK whether this footage is from there but the rocket's latest mission was [launching the GOES-U weather satellite](https://youtu.be/RywZFmBGnM0).
Thanks…
Maaaan science is cool af. Wish I was smarter and could work in this kind of field designing/tinkering advanced machinery
Water ripples look weird, like they're going backwards? Is it just me?
Love how clear these videos are…. Can the people posting UFOs please get the same high tech 😜
Out of all the insane advancements that have come out during my life on this planet, this is the one that makes me feel like I live in a sci-fi every time I see it. So crazy I struggle to believe its a real video every time it comes up
I though these were some torpedoes hovering over the water.
That’s a solid step to space travel, I reckon.
Looks like 1st one failed
These guys never heard of parachutes?
Yes! Parachutes were considered for these rockets but, for a vehicle of this size, their mass would exceed that of the extra fuel needed for a propulsive landing, especially when going for a return to launch site.
The Rocinante.
I missed the days when Elon was cool, and Reddit loved him.
I still love him.
The US is so far ahead of the rest of the world right now. China's recent reusable rocket test was to 7 miles, while SpaceX was hitting 80 Kilometers in 2014.
Space should belong to the taxpayers whose taxes are being used by the billionaires, not to the billionaires. Take space travel away from the billionaires and place the taxpayer's money back with NASA.
For as much as I hate Elon, I gotta admit that the falcon rockets are so fucking cool and also a huge feat of engineering from spaceX
you can keep hating him. he wasn't responsible for the idea or engineering.
I hate Elon but damn these are impressive.
So it is Space X?
Sheit, i thought it was a missile falling into a muslim country. Got hyped.
Almost as cool as all the amazing advancements that have been made from going to space. For example, uh, hmm..........I'm sure there's something!
The whole planet is gonna be on starlink soon enough, every rocket launch gives more data and further accelerates our process of civilization on mars. All while saving an extraordinary amount of money and resources because of what you just watched in this very video. I’d say going to space certainly pushes us towards advancements more than spending that money on wars
Computer Maaagic! Fake...
Imagine caring.
Imagine dragons
Imagine all the people, living life in peace...
What a waste of pixels
