Great ^^ thank you.
High quality very good video thanks.
Nice!
This is a great update to what happened during the test. I was under the impression that the chute got tangled and only partially deployed, but this video clearly shows it disintegrating under the stress. Thanks for the update. Hope the next test goes just as planned. Looking forward to larger payloads on Mars.
I'm also reminded how impressed I was with the precision the rocket motors had during spin-up and then stabilized flight. Very cool to watch.
Nice to see NASA switching back to a more failure-accepting position again. Taking risks with cheap programs is how you get things done
I like how you tone it down for general audience. You clearly discuss goals, your method, results and discuss what you learnt to conduct future experiments. No one really gets bored with cool stuff from NASA so all in all a perfect example to use for teaching kids about basics of scientific communication.
I was really impressed by how accurate the vehicle was de-spun, it was so precise.
why did they spin it like that anyways?
It's pretty amazing that these guys make this stuff.
Very cool! I love the explanations of what I'm watching! It makes the video that much more interesting.
Did anyone else read this as "LSD: Supersonic Test Flight?"
This and more, from just half of every penny on the tax dollar. Imagine what we would be testing right now if NASA got the military's budget...
If NASA had that kind of cash, you and I would be drinking martinis on Mars this weekend!

More likely you'd be speaking Russian right now.

Okay, I'll admit it: I don't get it. If NASA had a budget as large as the US military, we'd be speaking Russian? Do you mean, if the military budget was shifted over to NASA, then we wouldn't have the strength to keep Putin on his side of the planet?
Sorry to go clueless like this. Mostly, I'm worried about those Martian martinis!
By the way, I checked out your channel subscription. Amazing - that's all I'm saying. I mean, I don't want to get into a smack-down with someone who's subscribed to Neil deGrasse Tyson, atom central, AND Bright Enlightenment!
No - thank YOU!
Yeah, NASA get's half of a percent of the entire US budget, which is obviously still a lot for most people, is still so minuscule if you think about all the benefits NASA has given the world. NASA invented Velcro, gave way to modern insulation, set up multiple weather satellites, explored the surface of other planets and satellites, ect.

Sadly, velcro is one of the things NASA can't take credit for. But, if you google "Nasa spin off technologies," you'll see they DID come up with LED lights, cordless vacuum cleaners, scratch-resistant lenses, aircraft anti-icing systems, image enhancement and water purification technologies, those grooved runways that make aircraft landings safer (and highway driving, too), memory foam, blah blah blah.
NASA is one of the few government agencies that gives us a massive return on the investment. If you drive a car, use a computer, or fly anywhere, you'll get it done safer and more efficiently because of NASA.
I'm sure Stanley Kubrick would be the first to say, "I didn't fake the moon landings - and I didn't invent the Dustbuster, either!"
Scumbagel - a brilliant name with an avatar to match.
Am I the only one who really thinks this guys voice is just nice to listen to? Seriously no homo but you have a really nice commentating voice.
Great job on the test. Excellent video of the chute coming apart, I assume there is a lot of knowledge in all that video to work with. Great job overall, and I hope this turns into a great new tech available for mankind to use in the future.
This is the only last sign of humanity working together as one to achieve a greater purpose.
I watched this live at the time, and it was pretty cool :P Cant wait to see more progress.
Wow shredded chute! This task is a lot to ask of fabric. I am sure the next test will be as exciting.
Had this problem on a much smaller scale. Figured out how to deploy streamers first and then after a delay/slow down deploy a parachute without ripping it to shreds. I hope they can figure out a similar solution for this project. Good luck!
I hired a man who is having tough times to help him out and got the surprise of my life! The most inspiring video I ever filmed.
Some thoughts on this test of the saucer cushion test. First off, the atmosphere on Mars is much thinner. Secondly, why stop the spin rate? It(spin rate) will help to manuever the saucer and keep it steady during decent. It ALSO helps diffuse much of that extremely turbulent and chaotic wake enviroment into a better organized wake enviroment. You actually want to spin the wake and not allow it to control itself(it won't, its chaos). The spin adds the organization to chaos just as an atom spin signifies organization.
***** Exactly- Force is Force. Gravity, density, velocity, and cross section matter for this test. Mimicking the FORCES involved provide a stable test bench even if the variables are moved around.
why did they spin it? to keep it more stable? are this gyroscopic forces really needed? Or is ot to create an artificial gravity inside?
same reason they spin a bullet out of a rifle/cannon. If you don't know then look it up to be more ACCURATE with your understanding
***** I like that idea. The chute could actually be designed to spin opposite from the craft providing even more stability of the two...
"First off, the atmosphere on Mars is much thinner."
which is why they take it up so high first, so the density are similar to what it would encounter on mars as it would try to slow down for landing.
Fascinating!
Indeed!
You're a proud NASA geek if, like me, you watched this video of a parachute being torn apart and you thought, "This is SO cool!"
The parachute had to die. Good luck with the next tests!
fantastic ! wonderfull adventure ! the needing of cleanliness approach for this complete is very important.
What about your clean room and cleanliness guidelines ?
This test must have made quite an impact.
*#LDSD**: NASA's Supersonic Test Flight (HD)*
So I just saw the june 2015 live feed. This is a test vehicle right? We saw the SIAD inflate and just a few seconds after that deployment of the parachute. Wasn't that fast? Shouldn't the donut be given some time to decelerate the vehicle? Or does it already decelerate the vehicle by 1.5 mach (from 4 to 2.5) in a few seconds? And why not try testing multiple parachutes in one test? Test one chute design, see how it holds and whether its deceleration of the vehicle is as designed, and the cut it loose and deploy another? Just so you can test multiple designs in one go? Then the best design can be chosen. :)
so, does parachute failure indicate a failure or a success of the test as a whole? Or, does it just indicate that design changes are needed?
I thought the title said LSD for a second i was like damn NASA
Will the parachute react the same way in the atmosphere (or lack there of) of Mars? Perhaps a lighter and more aerodynamic ballut will keep the parachute from tearing. Seems like it pulled the chute too hard and shredded it.
Is a second parachute an Option in the design or just the one? Hope you can fix it. Did the parachute break up the same way in the ground tests or it didn't happen? Destruction of?
Nice Presentation.
So beautiful, I almost cried :)
This footage is so cool.
The news said "flying saucer" so I figured they spotted aliens. I should've known better
Awesomeness abounds
That was bad ass.
Why is it that much more people are interested in a pig surfing than this xD
What kind of rocket motors are used for spinning and de-spinning the vehicle?
excellent . I wish you more
The propulsion tube fuel blast is one of many I inspected. I don't understand the reason for it or the cost.
To me it looks like they got the centre of gravity wrong when they located the spinning thrusters! That was not a very straight flight!
Am I wrong? is there a reason to the wobble spin?
Awesome. Question: Why do they need to wait until June of 2015 to test again? I.e. why can't they test sooner?
I imagine that re-engineering the parachute will take time. And they're not going to use an untested parachute on an expensive test vehicle, so it's going to need to be tested again (using the rocket sled like the last one?). And I'm sure that availability of the test facilities also adds time to the test schedule.
god i hope the people who disliked this video dont breed
If you need a bit of problem resolution with the parachute system go find some of the gray hairs who did the Apollo Earth Recovery Systems. Thanks for not sub-contracting the project and the jobs overseas! Good luck!
Hats off to NASA.
Oh I remember hearing about this test and initial reports were that the chute didn't fully deploy. I see now that the chute in fact ripped itself to shreds. Successful test. Unsuccessful chute.
How did NASA use parachutes on the moon if the moon does not have an atmosphere?
eric maina they didn't
Use a deployable wing designed to create drag instead of parachute. It might last longer when you drag it behind the vehicle. I have some design ideas. Let me know if you want to chat.
Why you have to spin it for stability?
Nooo not the parachute problem again :(, They had the same problem in the lab prior to the test flight.
Why don't you use gyroscopic precession and utilize the torque vector created when you spin the disk? At that altitude you could probably spin it fast enough (without too much friction) to create an upward force to slow its descent towards the planet. Don't use a parachute, slowly retract blades from the disk that will allow it to "helicopter" itself down to the surface. Sort of like maple tree seeds spinning down to earth. You might not land exactly where you want, but you can always choose a site safe enough to widen the target landing zone. Is this a good idea? Is there an official place I can submit ideas to NASA? I love brainstorming!
Question- where are the stars?
We need this in Kerbal Space Program
Sorry the chute got all snarky. Hope you can tame it!
I don't get it - those super sonic parachutes seems to fail 2/3 times, isn't it a dead end?
Supersonic parachutes have been used on every Mars landing mission to date, and so far there have been no known chute failures from any of those missions.
The issue with this test was that they have to make a "huge" parachute - much larger than ever used before. The parachutes used on other planetary missions have (correct me if I'm wrong) a 100% success rate. We want to land some really big stuff on Mars and we have to have a really big parachute to do that.
aSuspiciousPete... science.... testing. test video. never been done at this size or speed. its called a failure. we then move on and try harder. that's called engineering. :) making the impossible possible
David Duvall Why can't they just use retro rockets to slow down instead of having a parachute?
why do that when they can have a parachute. and dont point to the failure above. thats why they test. Nothing you take for granted was built in a day.
It's stuff like this that the US should spend their federal budget on.
Through many failure will come success! Never stop failing NASA.
Makes me want to play Kerbal some more!
I hope to be alive when 'little pink men' invade Mars in a flying saucer. LOL. On a more serious note, this is doing my heart good seeing us (the human race) doing some more exploration and going boldly where no human has gone before.
Don Pfoutz to them we would be "big pink men"
So is this no go? Did NASA abandon Low-Density Supersonic Decelerator ? I am wondering cause SpaceX plans to test Red Dragon in 2018 and I presume NASA will share some of the data on what they found out.
Yes, LDSD has been discontinued
So do I hear the vibrations or the does the camera pick up the noise?
Camera picks up noise. The craft wasn't quite out of the atmosphere, so we still got sound.
sad that after over 45 years we are still using and testing things based on very old technology
amazing.
Dam that's something else
Wait so what's the point of this whole test?
I wish I could do this for a job..... building and testing space craft systems........ oh ya........ I can feel it... :D
This is too cool
Awesome work NASA.
I tought that supersonic chutes would be using different geometry..
So in other words, our plans to invade Mars is on schedule.
Keep at it, NASA! You ate the future saviors of the human race!
This is amazing! O.o
adorei o video
I really want to hear about the Thermals that the SIAD was exposed to.
who does not [does'nt] like jumping off the routemaster before it's stopped
kinda cool. Thanks for sharing, nasa.
HI-Definituon, Hi-Resolution, Hi-Speed never-before-seen footage. (In black & white.)
вот действительно достойный пример чем стоит заниматься США, а не терроризмом и войнами в других странах...
p.s США спонсор мирового терроризма, сейчас это четко видно по Украине, пишу как житель Украины. я уверен, что жители США не хотят такой репутации для себя, но факт остается фактом благодаря их власти.
nice saucer, i wounder when you go metric except the pound wich is a metric measurement 0,4545kg
Great 👍👍
Mars' gravity is weaker and its atmosphere thinner. Doesn't that translate into less turbulence in the wind drag and less weight on the parachute?
Might as well of used multiple streamers before chute deployment
Instead of releasing the balloon could the hydrogen in the balloon be pulled in and compressed into the rocket and used as more fuell? Maybe retro rockets for re-entry.
Now NASA is going to use the very clever go to answer. "We already thought of that."
It uses a solid rocket motor, so there's no option for hydrogen reuse here.
There are exothermic uses for hydrogen with oxygen on-board the space plane. In space, even low space, there is no air to slow thrust so Newtons Laws of motion on the space plane are 100% for the space plane and zero for air resistance.
Très bien mis en scène celui ci.. :)?
Very inteligent thank you Dear NASA .G OD bless every one my fellows.
Since in the proverbial idea space invasion by air balloons instead of environmentally friendly fuel engines
pretty cool
what was that? a technology of what?
We`re going to kick some alien ass
The narrator is talking like some CZcamsr doing a DIY video.
1:24. If that's the Sun, why does it appear so close? What is going on here?
Its just the big glare from the sun.
Same reason why the Earth looks flat lol
As it turns out the sun is a lot bigger than it looks on the surface.
Aliens.
its not the sun, it's a reflection of light which tends to happens on fish eye lens as it bends light. wth is up with you guys?
linkshellvendor
And I quote myself, "If that's the sun". Emphasis on "if". Nothing wrong with us. By the way, how do you know it's a reflection? Professional photographer? What do you do for a living?
Awesome! :-)
Ovo je priča za malu decu. isto kao i sletanje na Mesec 1969, godine.
Why not just use reverse propulsion? A 10 year old could tell you a parachute would rip under those circumstances.
All these "experts" in the comments telling NASA how terrible they are at designing parachutes make me laugh.
I'm not a specialist but I didn't see anything like a flying saucer in this video... :)
How about reporting in SI units to get your fellow countrymen accustomed to the units you yourself (and 95% of the worlds population) use on a daily basis?
I don't want other users to start some kind of a comment war over messurement systems, it's just a friendly suggestion to JPL as well as other scientific and engineering organisations in the U.S.
I hope I am among the majority of people who didn't understand the things said in this video.
Whoa,...... I thought this was going to be a supersonic flight on LSD.
Like......my bad.
Why can't NASA afford a GoPro? (Yes, GoPro works in outer space and underwater)
This test actually did use GoPro cameras on the top deck and camera mast.
GOTTA GO FAST!
ya need alot stronger material for the chutes .....
