"How do you get satellites into orbit?" "We basically just throw them really hard."

The issue is the projectiles are limited in payload as the payload has to be designed to withstand the launch system, rather than it's primary mission upon delivery.

Hate 2 see what happens when it miss the exit by millisecond 💥

how in the world do they possibly get the timing down too that precision too launch out perfectly through that machine. This is truly incredible.....

How it doesn't destroy itself upon release is quite impressive, that's a huge amount of unbalanced weight to be spinning.

At this point I am beginning to think that this is really a stealth pitch to the military instead of a space launch system. Change the launch arm to a wheel so you can launch multiple projectiles at once, spin it up to sub orbital speeds and you could deliver a dozen or more payloads weighting multiple tons each to any point on the planet. Even if you can only get the range up to a thousand miles or something along those lines it would still make for one hell of an artillery piece.

I'm getting OceanGate vibes. 😂

I am skeptical that this technology would work. To many issues I can see with this, for example the machine would need to be much larger and spin much faster to reach the needed escape velocity needed. The larger it gets would make it harder to reach the near vacuum the needed inside the chamber. As the machine spins faster how will they keep it stable and have it release at the right moment.

ACME Centrifugal Space Cannon. Wyle E. Coyote. Super Genius.

As large as that structure is, I find it hard to believe it contains 2.2 million tons of steel. That would be about 30% of the total annual UK steel output and be worth at least 4 billion dollars, without cost of construction.

The exit release off by microseconds, the projectile slams into the exit port walls and the whole thing blows up. Just a matter of time as to when that happens. In the meantime, no people can be launched with it, and the electronics of most devices get shattered without major reinforcement, adding to weight. Really, a rocket launch system. That means the base should be pivotable on a rotational axis to aim it.

Imagine building that in space. That could really speed things up without waiting.

There is so far zero evidence that this approach can scale to the speeds and masses needed to be useful. SpinLaunch doesn't talk or outright bullies anyone who tries to question the necessary engineering breakthroughs to make this work.

Looking at this system there many issues: 1. How out of balance with the system be at full size when you release the mass? The higher the rotational velocity the greater the force applied. This is a V^2 relationship, where when you double the velocity the force increases by 4. When the mass is released, the force for the counterbalance will be in the opposite direction will be the same and unless there is somewhere to either drop the mass or stop the rotation rapidly, the system will fly apart. 2. At 5,000 files per hour debris from the breakable seal holding the vacuum with be very damaging to the projectile launched. At 5,000mph that is the equivalent to 7,333 feet per second. Anything capable of holding 14psi of pressure out in an opening that large is going to cause a lot of damage. Having the projectile breaking through it may look cool, but it is a disaster for the object traveling at that speed. 3. When the projectile encounters the atmosphere at 5,000mph both the shock and ram pressure heating will be tremendous. The only materials to be able to survive that are either ceramic, and or Carbon/Carbon structures. The carbon structures do not do well with impacts, and the ceramic's are very heavy. This is nothing more than snake oil being sold to low resolution thinking individuals. Just these three issues alone make this implausible, and there are many more. Any time someone tells me that this is ecologically sound, alarm bell go foo saying "Scam Alert".

This is absolutely mindblowing! Always wondered why spinning launchers and long rail guns weren’t attempted to launch things into space. Amazing to see it being tried.

Impressive to see how far they came. I saw this from the start.

Begs the question......the projectile and payload must both withstand immense G-loading, so that would seriously limit the types of permissible payload and also require intense engineering of the projectile and any systems/components carried. Seems like a very limited scope launch system albeit much lower cost per mission. Most of the G-load concerns would go away if this was a linear launch system but would require an extremely long distance.....about 400 miles if acceleration is 5g to reach 5000 mph (guestimated velocity to reach low-earth orbit as per this video) which likely explains his circular launch concept.

Wouldn't this be more efficient if this is done closer to the equator so as to leverage the earth's spin?

In the videos you can see some of them go through at an angle which would slow them down incredibly. They had this issue months ago, if they fix it great, but the launches aren’t consistent. If they can get it working properly you could send satellites in pieces and connect them via a remote control or something

As a nanosatellite delivery system, it’s quite clever. If it can free up traditional rocket launches for smaller payloads, that reduces demand for rocket delivery, helping to drive the market to lower costs.

This sounds like something that works in theory, but is massively impractical in reality.

Fascinating but I wonder if upscaling will be maxed out at some point. I love the concept, but question its actual payload abilities.

It is always pleasure and pleasing to meet ones who were supposed to work. Thankyou congratulations. Thankyou for visiting me.

Amazing. Happy that we have clever folks like this in the US

This may be an improvment on my idea of using a giant rubber band to slingshot obects into space. One difference is that our plan involves launching the object parallel to the ground to the horizon instead of up because we would have to dig a hole deep enough to pull the rubber band back far enough. The next impediment is that there is not a long enough flat surface on which to mount the slingshot because the Earth is curved. We are still working on that.

Wow! The projectile reaching maximum speed and then hitting the thickest part of Earth's atmosphere, I'd like to see that, from a distance.

I can't believe how many people think this will fail. I spent a few days running through calculations about a year ago when I first heard about Spin Launch. I looked at different weights, radius of rotation, several projectile geometries with different centers of mass, release timing requirements for stability for different projectiles, strengths of materials, drag through atmosphere upon release, etc, etc. After all the calculations, I found a range of acceptable parameters for certain materials, launch velocities, projectile designs, and a requirement on the time to release the front vs rear of the projectile. It's not impossible. In fact, the ranges are wider than I expected. Spin Launch will be successful if they have competent engineers. It's all about the design limits, and collecting good data to making everything balance. There's no magic here, just good design and hard work.

This makes my head spin.

Wow! For reference, the minimum escape velocity for Earth at ground level for ballistic objects like their launch vehicle is ~11.2km/sec or over *25,000mph* or Mach 33. Even the extremely fast "hypersonic" speed range starts _only_ at Mach 5. But will need a some more speed to account for atmospheric drag. The pressure and heat from atmospheric drag will be enormous. The launch vehicle exiting the barrel at such speed could cause a large shockwave perhaps. Really good concepts and challenges listed on Wikipedia: en.wikipedia.org/wiki/Escape_velocity Hope they can do it but using someone else's money and not any tax payer money.

The size this thing would need to be to launch anything of use to space would be crazy

I'd hate to be the guy who mistimes pressing the release button.

So what happens when all that weight is released and the wheel is unbalanced? Im sure theyve thought about it, but Ive seen large fans (think 5,000 Horse Power) rip themselves apart from small weight imbalances

Tbh.. looks like the massive wood chipper that I used to work near at a paper mill as a summer student back in the late '70's. Not quite as big but a beast of a machine.

They got this built for 150 million. That's cheap. I think we all have the same question: How this thing spins this fast and how you get it to perfectly release at the right point. The payload has to handle the rotation and G's of the launch..

I really like the idea of combining this with rocket boosters that kick on after launch! Seems like a win/win

The shaft of the orbital accelerator could suffer certain degree of damage due to the unbalanced loading on the object holding arm. Depending on the weight of load (rocket), it may need to replace the bearing frequently. Electromagnetic railguns should be able to launch much heavier aircraft/rocket.

Its a great idea but it would mainly have to be used for payloads that arent easily breakable unless they have a mechanism to protect the payload from the G-force being generated.

I saw this in a cartoon once, only it was a big slingshot with a really big rubber band...worked great !

Also - India currently (2014) spends $1.2 billion a year on its space program. In comparison, US space agency NASA has a budget of $17.5 billion for the year ending Sept. 30 2014

Didn't Thunderf00t already debunk this as a fraud?

They can save even more fuel as they can tune the engine bell of the rocket motor for the altitude it ignites/ orbit, as opposed to having a design that has to be a good fit from sea level to orbit. Could also be a good weapons system/ launcher. Another thought would be to add a kinetic energy recovery system (KERS) via a flywheel and generator to recover some of the energy as electricity.

America is huge that we can just things like this

Actually, it is based upon Winans Steam Gun, designed in 1858 and built in 1860, and found action during the Civil War. A full scale replica of Winans Steam Gun can be found today in Elkridge, Maryland.

Been following them and wish them nothing but the best … it’s cool to see new ways of getting things to space …

will anything more advanced than a rock survive the g-forces?

I don’t realize why so many in the community are hating on this…. If they had to get emergency supplies to ISS this is the way to go. Very little prep and wait on a launch. They still use fuel to complete the burn, but that’s ok! I know this isn’t viable for putting humans into space, but the company never said that was a plan!

Yes, launch costs are decreasing, but the costs of making electronic and mechanical hardware that can cope with the g force caused by rotation are increasing tens, maybe hundreds of times. In addition, when this hardware goes into space, the cost of durability required to withstand the g force becomes a waste...

I hate seeing Spinlaunch associated with such things. Yes, centrifugal slings are potentially useful on the moon, asteroids, or in free space. But Spinlaunch isn't working on such applications, and most of what they are working on won't be applicable. You don't need the vacuum chamber, you aren't limited to such a short radius of rotation and high acceleration forces, you don't need a near-orbital rocket stage with a discardable aeroshell that can survive sea level hypersonic flight... Spinlaunch isn't about efficient lunar payload launches, they're about getting investor funding by pushing a fallacy that orbital launch here on Earth is expensive due to propellant costs. By the time we're building lunar slings, they won't be around any more.

This is Great. I cannot fathom but admire the imaginations and greatness of human mind. Support this from Kenya.

The projectile can still use fuel to boost the flight even further. To gain momentum.

i think it was a bit misleading that they didn't mention until the very end that the high G forces of this launch method make it unsuitable for manned launches. In fact, quite a lot of unmanned launches wouldn't work because the payload wouldn't withstand the high G forces. However, for payloads that can handle those G forces, it shows a lot of promise.

If I was the owner of spin launch I would be bragging on how high I launched my projectiles to date !

It's incredible! I hope everything will going right!

We all need to unite as one species of one planet if we are ever going to have a chance at going out there and staking our claim.We will discover things in space that are way beyond our understanding and strength as any single nation.

Building the launcher at 10,000' elevation or higher might help, as the air is significantly thinner there.

its been cool to follow the development of this. its a crazy concept. when i listen to the designers, i really believe in what they are saying, all the same i still have this feeling of skepticism

So is this how they are releasing alien tech without getting in trouble. Under a rouse!?

Wow, it will be interesting to see where this tech is in 50 years! 😳😳😳😳😳

This is a very interesting innovation. I hope it really takes off.

Love the design ! Reminds me a little of the movie "Contact" with Jodie Foster :)

Whatever works! It’s the idea that matters, being positive and productive for humanity’s development 😊

This would be useful for chucking materials and other robust payload into space. Anything delicate like a person will have to use conventional launch.

I've always envisioned a much larger space station with a mother ship where it is docked and can be loaded with supplies and any upgrades that it needs for a journey. Also, modules that could be added to it over time. The astronauts would fly up on a smaller rocket.

10.000g. Hahahahaha! Satellites will be chunky salsa.

As a space fan, follow spaceX and the rest, I must say. You all rock for being different. Can't wait to see the full build and testing. I'll follow all the way when it's the full sized one being tested. Investors better invest!

Interesting, they need very high vacuum, more than you can get with just a mechanical pump and are using what looks to be a giant size diffusion pump to get it. I guess that would scale better and be less expensive than a turbomolecular pump

This was discussed in 2013 glad to see it today

I have been a Spinlaunch fan for years, not just because Yeeting satellites amuses me. I'm glad to see the press picking up on some of the other young aerospace companies with less self-promoting but equally intelligent CEOs as they work to bring the tried and true but outdated commercial aerospace industry my Dad worked for into the 21st century. (Too many people don't realize that commercial aerospace has been around as long as weather and telecommunications satellites and the US nuclear program - NASA just provided a more peaceful, civilian, and scientific purpose and R&D for ICBMs).

Great concept but what they didn't show was that the projectile doesn't fly strait when released is wobbles back and forth causing excessive amounts of drag.

It’ll be ready in about 5 years and they’ve been working on it since 2014 so it’s taking them 14 years total to get it working 😊

Freaking awesome! I for one wish them a ton of success and can’t wait to see their evolution of spin lunch.

I feel like this isnt getting anywhere close to orbit. Saving a few gallons

How about building a SpinLaunch system at very high-elevation places (Hill Stations like the Himalayas) where the atmosphere is very thin?

So exciting, I wish them well‼️

How truly wonderful to hear a modern engineer say "aeroplane" instead of the crude, inelegant, "airplane"!

Part of the risk of that core technology involves damage to our ozone layer. This would significantly cut down on the damage done each time a heavy lift vehicle heads to orbit from earth. Bravo!

if people could survive such a launch I think this technology would have been developed sooner

Doesn't even matter if we use it once to send man into space, as long as it's able to send supplies, satellites, and other important cargo cheaply and more environmentally friendly as well as safer.. already the biggest win 🏆

Next up in our series of highly practical engineering solutions, the hyperloop.

Our ET friends said that as long as we use electricity our technology is going nowhere. They don't use it on their planets or in their ships.

I'm an investor in this company, they're doing great things 💪💪

The passengers can't handle the g force😂

its exciting stuff but the gap between where they are now and where they need to be is still a big one

I can imagine this being used on battlefields with small rockets sent hundred of miles away, using a much smaller version obviously. Imagine 3 full lines of this against an enemy would be devastating.

Man.....if Apple decided to make a big giant iPhone then it would fit right in there! 😂1:26

I'm surprised this money-pit project is getting a 2nd airing in 2023.

Spinlaunch sounds like it could be a plastic kids toy sold for 3 easy payments of 19.95 + shipping and handling batteries not included some assembly required

Good way to launch low budget satellites. However, spin launch is deadly for any living thing.

Wow! My fist thought, can it be used to send fuel to orbiting starships?

A lot of cool scams going on in the space space

Everyone seems to be having a great time saying, "astronomically expensive."

Most payload components need to withstand that centrifugal g-force and need a way turn that most into different directions to get a desired orbit path.

Dude better start showing some spectacular results and soon. It seems like everyday SpaceX has done something ingenious that's got the folks at NASA shaking their heads in amazement.

1963: "by 2020 we will have flying cars" 2023: "let's just yeet stuff out of a spinning cannon"

It feels a lot like Theranos. Hopefully this works

"I was sitting in my mom's lap at 3 years old learning how to fly a plane" talk about winning the parents lottery, a platinum spoon. an out-liar

Yeah....hard, hard pass on investing in this one. They might be able to design an elaborate skeet launcher, but that's about it. No satellite with modern tech would be functional after that level of G-force. Also, if we weren't able to put satellites into orbit with a giant cannon, then there ain't a chance in hell we are doing it with a sling. I'm sure this guy skipped a few physics lessons in his day. Thank God that he isn't building submarines...

I pray we redirect our focus to finding, acquiring, and securing sustainable, cost-effective, renewable building materials that can sustain or be easily replaced by these new storms… Space can wait💪✨

Why don't they laych it from a high altitude location? They could save a few kilometers of dense atmosphere.

Another Elizabeth Holmes in the making or Nikola.
