This isn't new, it's a 10yr old company

[@atenrok]

Should be bankrupt by now...

[@pef1960]

SpinLaunch is already a dead duck...

[@JohnPowell6]

Spinlaunch is a great idea - for the Moon or other airless bodies.

[@Leafbinder]

but cant launch a Manned Rocket!

[@Jondiceful]

Particularly those with lower a gravity force to overcome.

[@roveriia6334]

Great idea? explain please

[@andrewc662]

An electromagnetic railgun would probably be easier.

[@reisrosenbloom]

I think its more likely we have space zeppelins before this works

[@atenrok]

..or space elevator 😉

[@roveriia6334]

Boondogle where the top executives make a ton of money and will eventually walk away

[@NelsonZAPTM]

I want a space Zeppelin, with a pirate ship suspending below. Something like in the movie Stadust.

[@NelsonZAPTM]

​@atenrok don't be silly, that's actually possible 😉

[@JoeSmith-cy9wj]

Elegant ideas should never be dismissed. However most serious physicists have debunked this pie in the sky theory. The materials and designs required to make this practical just aren't available now, if ever.

[@roveriia6334]

its a money grab by the leaders. sucker investors

[@larryscott3982]

Spin Launch is as unfeasible as hyper-loop

[@learnallican3627]

WOW! this seem like this wont work at all.

[@a-fl-man640]

the plural of spacecraft is spacecraft, not " spacecrafts"

[@egalitarian-rex]

Copy editing is almost nonexistent nowadays. Apparently, standards are elitist.

[@leadboots72]

Is this a joke, Nova? Why publish this?

[@_MaxHeadroom_]

100% won't be the end of traditional rockets because the G forces are insanely high so it could never be used for human spaceflight. Also in order to have anywhere near a Starship equivalent payload the launcher would need to be incomprehensibly huge

[@ebbiketrip2497]

“I’m not an engineer …”. That sums this up

[@roveriia6334]

Appearently the investors are deaf

[@Smokeisprogress]

Has anyone ever gotten close to getting this to work in atmo? Seems like something to fleece investors and maybe sucker a grant from some pentagon office.

[@jimshreve83]

A smaller version should be built on the Moon and Mars to be used daily to keep the astronauts' bones strong. A small version of the tilt o rama carnival ride using electric motors and solar would be a game changer for the health of the inhabitants.

[@themaddgamer2112]

You're not spin launching people into orbit. Many payloads won't survive the spin either.

[@TheChumzo]

As an aerospace engineer I don't think this is feasible.......but this is great and I want to be proved wrong. YEET!

[@bernzeppi]

Same 10,000G would be felt in a gun to reach the same velocity except it happens over shorter duration. Just make the electric motor a linear accelerator.

[@Danger_mouse]

It's still a pie in the sky system. Short of throwing rocks into space, nothing else useful with survive the G forces. Change the batteries, great, what about the electronics, the propellants and motors needed for final orbit adjustment? How many completely solid state, non deploying (solar panel arrays etc) are there lining up for a rock launcher???

[@AdRock]

They already gave up. This video is out of date.

[@homewall744]

Just user feathers and wax and fly into space.

[@billwhite1603]

I've been seeing this for a good while. I would like to know if you could spin an artillery shell 40 miles from a launcher you could mount on a truck.

[@marsrocket]

Did they pay you to post this? Hasn’t this nonsense gone on long enough? I thought they were n the verge of bankruptcy because it’s an idiotic idea.

[@Prifly70]

Thought the same exact thing.

[@kerrytodd3753]

If they ain’t they sure ought to be……must be Gubmit money.

[@happykillmore349]

Did inbreeding and fetal meth syndrome cause this comment?

[@atenrok]

Yes

[@ebbiketrip2497]

Ditto. Was thinking the same thing

[@Sloshy_garage]

5:13 this guy is giving off huge scam vibes 😂

[@birgirkarl]

This 'scammer' is Adam Steltzner, the lead engineer behind the Mars lander, Curiosity rover.

[@Ohfiveoh_]

Seems like a lot of extra work 😅

[@anthonytimpson4975]

it'd need to spin so fast as to put the payload under thousands of Gs.. Thunderf00t tore this crap to shreds years ago..

[@homewall744]

You'll arrive in space dead and products broken into pieces from the dizzying spin

[@NelsonZAPTM]

Not broken, painted onto the floor.

[@MoneySavingVideos]

I like the elevator to space

[@Leafbinder]

no like throwing speghetti against the wall , no human can survive the G`s of this process.

[@albeit1]

Space elevators won’t work either. Anything going up a space elevator still has to accelerate horizontally somehow. That requires fuel. And that’s even harder when you’re trying not move the elevator.

[@dougaltolan3017]

​@@albeit1You are right that angular velocity isn't addressed in the basic (simple) presentation of a space elevator. But it is not a show stopper. If mass going up is balanced by mass coming down, there is no net acceleration. If balance cannot be achieved then the counterweight can be made to advance beyond Earth's (or wherever) rotation. That way "up" is in the direction of rotation, and climbing will also provide the required angular force. You might now have some mental image of the top of the elevator whipping about. Sure, but do the calculations before assuming that it is critical.

[@john762x51]

isn't this company already gone under

[@leadboots72]

I thought so as well

[@vegasflyboy67]

Love me some pie in the sky.🤩

[@liamguitars]

Wouldn't a electromagnetic super maglev ramp be a little easier ? No idea I just want to see GIANTMUNGOUS ramps

[@ScottGrammer]

So let me see. We begin with a rotating arm, balanced so that it won't vibrate excessively while spinning up. A tremendous amount of rotational power is applied to get the velocity of the payload at one end of the arm up to where it can escape Earth's gravity. That means it has to be moving at about 25,000 MPH - AFTER - moving unpowered through miles of atmosphere. So the finely-balanced arm is spinning like crazy, and the payload is suddenly released - immediately unbalancing the spinning arm. Gee, I wonder what happens to that spinning arm?

[@swill128]

Look them up on real engineering. They address it. You can drop a counterweight or lengthen the arm when the payload is released.

[@JustinMShaw]

They specifically said that the payload would be lifted to 40 miles, not that it would escape the Earth's gravity. Even the rocket that would kick in after that would just lift it to orbit, which is still short of escaping Earth's gravity.

[@wally7856]

@@JustinMShaw You cannot "lift" anything to orbit. You have to accelerate it to orbit to reach a velocity of ~17,500mph/25,000 kmh. You fall down otherwise no matter how high you are. You cannot escape Earth's gravity with this thing. Look how far away the Moon is and Earth's gravity holds it in place just fine, hell the Earth wiggles the Sun from it's pull. There is still 97% of Earth's gravity at the space station, they just don't feel it because they are falling (orbit). You also can't throw anything into orbit, it'll always come back and hit you in the head. You need to do a second velocity change at apogee to circularize the orbit. This means that whatever this thing plans to throw into orbit, it needs a rocket built into it.

[@JustinMShaw]

@@wally7856 That's a funny thing to claim when aviation uses the term "lift" to increase elevation. Bonus clue - lifting anything off the ground by any means involves acceleration. And screw you for pretending that I didn't know orbital velocity. Your assumptions are pathetic.

[@CountYourblessings0]

This spacecraft could also need a heat shield as it plowed through the atmosphere starting at a high speed and gradually slowing down until it reached space at which point a rocket stage would have to ignite and burn long and hard to bring it up to orbital speed.

[@villageid10t53]

Did I miss the part where the empty spaces within the cube sat were filled with a medium other than air? But what would I know? 🧐

[@Internet-Antics]

What about when it hits the atmosphere? If air presents too much friction for the launch, what about the majority of the trip through the atmosphere?

[@andrewsmactips]

The plural of spacecraft is spacecraft. Just saying.

[@CountYourblessings0]

I'm reminded of those old videos of astronaut candidates being spun around in the centrifuge. It looked pretty unpleasant and that level of spin wouldn't be anywhere near enough to launch them into space.

[@LordDustinDeWynd]

Notice the lateral translation as it comes out? That's what's keeping them from going live, they are unable to release instantaneously and therefore cannot calculate the trajectory of the payload. An inch/centimeter out of alignment on earth means miles/kilometers out of alignment at orbital altitudes.

[@nnitro527]

just saw that yeah....its very unpredictable, i dont see this ever working out.

[@swill128]

Rockets don't go in a straight line. They can turn and course correct..

[@elmartillo7931]

Absolutely ridiculous waste of money. This is not viable. I'm a mechanical power engineer with 30 years experience, this is a ridiculous pipe dream. And 10,000 g's? Yeah and how much is the payload going to cost to engineer and design to withstand those types of g-forces? Why focus millions of dollars and Maron hours trying to create a technology like this when all of that time effort and money could be put into making existing technologies better? And who is this going to benefit? The people working there that's it. This is like money laundering. Let me guess they get most of their funding from anonymous donations 😉

[@MrBrokenwrenches]

The Yeeter 9,000

[@TheOpticalFreak]

Uhm... This is old! Those guys are already broke the company is bust! 😝👎

[@MrDhalli6500]

I particularly like the part @11:12 mark, where the projectile didn't leave a clean hole like a bullet does on a paper target. Yikes. Yea that's gonna be a problem leaving the launch tube sideways. They may have to put a spin on the projectile, like a quarterback does on a football.

[@unotechrih8040]

If you want to cover the true future of spaceflight, cover Starship.

[@JJs_playground]

We'll get a space elevator before we get this.

[@roveriia6334]

This ia a gravy train for the executives wasting stupid investors money. This will never work They provide the proof with no data, no requirements, and then they provide solutions to batteries. How about proof of escape volocity? What about sensetive satallite instruments, which experience only 3 G's rather than 10,000 Gs? Run away, investors. I hope this saves one person from loosing their money to these snake oil salesmen.

[@wally7856]

Too late, they already took the money and ran.

[@daveseddon5227]

You may well be correct. They obviously purchased this 9:57 from a Sci-Fi movie set! 🤣 How much did that high-tech office/observation unit cost?

A reminder from the same 50's & 60's... He who controls space, controls the world. Least we not forget.

[@ATop1x]

Hahahaha, new? Wtf spin launch has been around since 2014, and there has only been like 1 successful sub orbital launch. Also, how are you going to send people up without out turning them into a smoothie at 10000g's?

Old video, and its just a dumb idea, Nova, lol

[@donaldbohn3183]

It would work for Payloads, not for People.

[@Zindo.Majesty.HisMajesty]

Lots of G’s that the satellite has to withstand.

[@AySz88]

An incredible fraction of fuel in a traditional rocket is "spent" during the slow, heavy beginning of the launch, fighting gravity to build speed. Just giving it a kick start will save massive amounts of weight. Hopefully they can build light and strong enough make this work, even if they eventually need more from regular rocket engines than they think.

[@anthonytimpson4975]

is the energy to spin it up suddenly free? this idea was idiotic years ago and ius idiotic now

[@AySz88]

@anthonytimpson4975 The relevant constraint for rockets isn't energy, but momentum.

[@anthonytimpson4975]

@@AySz88 how do you build up momentum?

[@JustinMShaw]

@@anthonytimpson4975 The energy needed for the initial boost may not be lower for this than for a rocket, but the rocket requires fuel while this requires electricity.

The second it hits the atmosphere it's going to start decelerating.

Ok inert payloads only. Is their research only addressing MAX Q or are there other issues?

[@Leafbinder]

Go SpaceX GO ELON !!!

[@nnitro527]

Is it more energy efficient though, in the end its using energy to spin and accelerare with fosil fuels or similar, whats the point. If it requires less energy it could be good, maybe they use gravity so it doesnt use as much energy for the spin idk.

[@kumaranmani]

I hope there are no taxpayer grants going into this

[@briankleinschmidt3664]

I see a lot of skepticism here. I once read a book called "The First Men on the Moon." They used a giant cannon to shoot themselves into space. So, the idea is not new. You can fire a person from a cannon. I've seen it done.

[@evanm6739]

Only good for for non fragile payload

[@LeonParrish-q6w]

Spinlaunch is radical alright, and not very practical. Not in an atmosphere.

[@garyfrancis6193]

Spacecraft has no plural form. “ Craft” referingbto vehicles has no plural form because it’s an uncountable noun. “ Crafts” eexists describing certain typs of manual production skills like weaving, pottery, knitting, carpentry. Thus people involved in construction trades are called “ craftsmen”. Uncountable nouns like tea, coffee, sugar, snow rain, happiness, money have no plural form.
