- We’re testing a new way of landing on Mars… by crashing into its surface.
The Simplified High Impact Energy Landing Device (SHIELD) is a lander concept being tested at NASA’s Jet Propulsion Laboratory (JPL). It could one day provide a new way for low-cost missions to land on Mars.
Rather than rely on parachutes or retrorockets, SHIELD would include a collapsible, accordion-like base to absorb the energy of a landing. A full-size prototype of the base was tested on Aug. 12, 2022. The prototype was hurled at the ground from the top of a nearly 90-foot-tall (27-meter-tall) drop tower at JPL. A steel plate ensured the impact was even harder than what would be experienced on Mars.
The design worked: After crushing against the steel plate at 110 mph (177 kph), several electronic components inside the SHIELD prototype, including a smartphone, survived the impact.

It's so crazy to see that much metal, moving that fast, deform like rubber.
It is amazing to see NASA has taken heavy inspiration from Kerbal Space Program and applied it to real life
I propose this alternate name for the system: SPLAT Lander ... Space Payload Lander At Terminal (velocities) Lander
A modification to not use Lander twice... Space Payload Lithobraking At Terminal (velocities) Lander
@@dalel3608 I like 'lithobraking' 👍🏻. I used 'lander' twice and really didn't like it. Yours is much better.
I think somebody was just trying really hard to name it "SHIELD"
I want to see a bunch of these tests now, with different sized rocks and sand and stuff for the landing surface.
I know an easy way.., just have the builders use the metric system and have the people flying it use the imperial system!
thats why we should abolish ALL measurment
@@ThatOpalGuy ..but then how will I know how many Leagues are in a Furlong??
@@rogerwilco1777 it'll be tough going at first.
Nice!
@@ThatOpalGuy . . . and replace them all with a time-tested unit of measurement: the Macedonian cubit!
If you could make a landing system without parachutes or propulsion landing. It would be complete game changer.
So... Lithobraking?
Kerbal space program would be proud.
So proud like an Argentinean (San Martin) lead the jet sequence of landing. Go Nasa go!!! GO JPL GO!!!
I can imagine some students building this to protect an egg!
But the probe seems to flip over after touchdown, so how will that be prevented?
The first test was into the desert floor. It didn't bounce in the slightest. In this test the steel plate bent and sprang back throwing the lander into the air.
You know, if you make it out of lightweight material, you wouldn't have to crash into Mars - it would just float down like a piece of paper.
While there is definitely an amount of weight that would float nicely in the thin Martian atmosphere, I imagine it would have to be so incredibly lightweight that you can't bring any particularly meaningful payloads -- after all, to make something heavy have enough drag to float slowly on Mars, it's a parachute lol
Superhero landing!
Safe lithobraking. Nice!
Lithocapture is an enabling technology.
A hardened launcher could be incorporated: dropping a penetrator, capturing a sample and launching back to orbit in a matter of seconds!
Awesome, really great work.
now i can safely send my cellphone to mars...
Spiral glider or auto gyro. Like helicopter 🌱 seeds.?
@@TheStockwell I was meaning for decending purposes.
Awesome 👍👍
Very nice work. Tons of modeling, both hard and digital. I think It's gonna need "articulated kickstands",, to right itself from upside down possibly. Be crazy not to have them, and a waste. Could use them to angle the rigid solar panels for sunlight aiming, for maximum power produce, and shaking the gravel and grit off the top. Could even walk the thing down onto the Planitia, or just a short distance for better science. legs, , Kickstands,,something like that. Plop on the gound uninjured, like a Potato bug, then get up and walk away. That would win the Christmas Turkey at JPL.
One mission could bring a "padded" landing pad to use subsequently.
Show the G load graph or what is the max G load.
NASA always thinking outside the box, love that!
Are you planning on using this method combined with the jet lander? (Like what you currently use, but instead of a parachute you have a shield) because this doesn't look close to survive a drop from space at hypersonic speeds
No I think so. The way they explained it is pretty much: you only land with the shock absorber. The rest of the interplanetary speed is taken care of by the atmosphere and a heat shield.
NASA should go back to the drawing board; this idea is to laughable; we need to build anti-gravity spaceships.
I think that they'd still use a parachute but this landing method replaces the sky crane or other rocket powered landing. Because those sky cranes are very expensive.
@@ChristinaVahlsing Zero way systems.
+1 to what Jaydon said, my intuition is that they would still use a parachute. Parachutes are the common element to practically all landing on bodies with atmospheres (Parachute + Airbags on Mars, Parachute + Skycrane/Jetpack on Mars, Parachutes on their own on Venus, Titan, etc etc). It's just that Mars' atmosphere is too thin for a parachute to be useful *on its own*. Having said that, Schiaparelli's impact speed was 300kph, close to its terminal velocity, so it's also wrong to claim that the impact would be hypersonic -- even without a parachute, a thin atmosphere will slow you down a bunch.
This seems like the end of “the landing ideas” rope for nasa
WAIT, that's it! Get me a long rope...
I was thinking of a way where the linear forces would be converted into rotational energy through a metallic ring . Thus , increasing the deformation cycle and providing gyroscopic stability due to disc rotation.
Wouldn't that be a bit too heavy for a phone protector.
So when will we be able to buy a NASA phone case made out of this?
How come carbon fiber structure isn't used, because Formula monocoque is able to also absorb a lot of the impact, but it's much lighter than the metal used.
Dumb question time!
But by new do you mean new to NASA?
Because if I remember right it was tried before, was it not ESA's Schiaparelli lander?
I mean it had a problem and landed to hard, but did that not use a crumble structure too?
Or maybe you will let it free-fall?
Relying only on the drag of the atmosphere to slow it before hitting the surface?
ESA did try use both parachutes and thrusters to slow Schiaparelli AFAIK.
I like this.
Wow great to see that 😁
Science!
Makes me think of the imperial probe on hoth landing
Dear NASA. Please give us the ability to comment on ALL your videos. I don't understand the inconsistency. Many thanks. 👍😎
Fantástico
Awesome
if you can build the science experiments to withstand that crashing into rock, go for it
Cool! Shows some promise!!
Please, NASA, consider this: pl.wikipedia.org/wiki/Zderzak_%C5%81%C4%85giewki
energy accumulation-dispersion converter - probably Cambridge has a patent, but the name of the inventor is Łągiewka. The device allows you to absorb most of the impact energy, without any special crush zones.
Awesome experiment, with being a success I hope one day cargo/humans/rovers + would land on Mars & other locations in universe with this crash landing method. All the best to NASA/JPL in their future activities/endeavours. 👌😃🙂
I don’t want to be in that when it crashes
It will never be used to land people - it's for cargo & robots.
What if it lands upside down or flips over on impact?
It's designed not to do that but of course it's a factor that they have to think about. This is JPL. They definitely have thought about it. As long as your centre of mass and centre of lift are placed correctly and you land on relatively flat terrain, you won't flip over
Oh I’m sure they’ve thought about it but it would be cool if they explained it a bit more 🚀
Is this noy going to have difficulty if it land on the edge of a large rock structure?
Like a few years ago when car crash tests started including the partial overlap frontal crash? And all the initial results were bad?
maybe put a habitable small artificial moon in orbit around Mars, where rockets / spaceships from earth can dock or attach to and the astronauts can live inside indefinitely (similar to international space station); and from which can go down to Mars surface from time to time for research and other activities?
Could indeed really lower the cost and simplify it, with I would think better chances of a successful landing.
Yeah, glass looks good. So, time to try with human. Any volunteer ? ;)
This is awesome JPL but can we let that NASA meatball logo go for good?
The point of a meatball logo is to make people hungry - hungry for human accomplishment! 🔭 = 🤤
Why don't you guy give it a spin with appropriate aerodynamic design could decrease the impact force
Crumple zones - used in cars for decades.
Next!...
There is something wrong in the text: if the test height is 27 metres and the test object is released in free fall, the impact velocity against the ground is not 177 km/h, but can only be ~83 km/h. best regards
Might want to rewatch the video Albert, they have a bungee pulling it down to accelerate it.
@@dalel3608 I think you are right. Sorry, thank you and best regards.
Try an egg lol
Whoa! Look at all the comments from armchair designers with the funding and technical expertise to tell JPL they've got a better system worked out! 😂
It can flip over.
So... they have a proven method of landing parachutes and sky crane and also the airbag method which also worked as well - And they are trying this? -Why don't they just used the ones that they know have delivered ?
This is way cheaper. Also simpler. Fewer parts = fewer possible failure points
cheaper, fewer failure points
That's how they're gonna drop humans off
110 MPH = 177 km/h
Sorry, but the terminal velocity of an object dropped from a height of 90 feet is only 52MPH.
Miss the bungee cord?
Too much Dragon Ball Z hahahahaha. The final prototype will be a ball.
Er..if I go to mars in the future I'd like to land on wheels please that method would hurt bad!😎😁👍
Ever had to ride in a car with a sprained shoulder or a femur that's just been put back together? Every bump is agony.
Now... imagine you're on the ship and you suffer a fracture 2 days before scheduled landing... :|
It really crash?
It's a good concept try with humans
🎱
No control sample? Would phone survive in some simple container filled with a foam? Poor demonstration of over engineered phone case...
Use water
…
I believe Mr musk, has already solved that prob???
by tweeting idiocy?
No he hasn't.
*Mr.* Musk? The last I heard, he was more appropriately addressed as St. Elon of Musk.
LOL! Mr Musk hasn't even left LEO...
Bubble wrap anyone? lol I love how NASA wastes money -- NOT !
like how you wasted education?
@@ThatOpalGuy LOL What education? ;p
Now put some of the real hardware you would send there and drop it. Also , well done caving in to the super small minority that cried about some easily removed debris on the planet. Nice job cowering.
I believe the British have an excellent expertise in the subject.
Dunno about this. Last time I heard about the British trying to crash into something, it was an old warship with a bunch of bombs stacked in the bow, paved over with concrete to hide them, and then they just rammed a dry dock in WWII.
It didn't end well for the ship.
