sad. Ingenuity was amazing though...

I don't know about that. I have seen some pretty wobbly ceiling fans spinning away, One report thinks that it landed on two legs pitching the blades into the dirt and damaging all 4 tips. Wouldn't we all be surprised if they were able to increase rotor speed and get enough for some lift to pace the rover. Never underestimate those miracle workers at JPL. We'll just have to see what they can come up with.

@@PC-nf3no Run that wobbly fan at 2400rpm and see what happens.

@@jlangevin65 well, you're right, it could be bad. Or, JPL could do what scientist do and run tests and see what they got. Categoric presumptions dont work here!

@@PC-nf3no I'm not even sure how to respond to you. I didn't make any categorical pronouncement, but now I will - Ingenuity will never fly again.

In the space flight industry (SFI), all terminology needs to able to be a TLA (three letter abbreviation). So SSA works whereas SA clearly does not. :-)

@@briandeschene8424 That would limit the number of possible abbreviations in the entire spaceflight industry to only 17,576. Not nearly enough.

​@@death_parade 46,656 (36^3) as numbers are allowed in 3LAs/TLAs though are used fairly infrequently in the SFI. I even hear it pronounced as "three ell ayys" regularly enough.

@@death_paradeNash they’ll just reuse the acronyms. Bonus points if they can use the same acronym twice in a sentence with different meanings!

​@@death_paradeoh, you poor soul. Allow me to show you one of the acronyms that the US govt uses. Not for space, but hey. AIMS Seems innocent enough, right? No. Stands for... ATCRBS IFF Mark XII System They'll just nest it if they have to. Or as mentioned, just reuse.

I wonder if it could be worthwhile to design blades with a weak point so that when they broke, both sides broke at the same place, remaining roughly balanced.

​@@drworm5007I think the problem would be that since it broke at the weak point, it wouldn't dissipate enough energy for the rotor to stop thus it would break again beyond the weak point. But idk it could work. I think the easiest is to not crash it 😂

Brilliant, I love it 👍

@jamesowens7176 Fascinating. I really do wish you and all the other people involved well in progressing this project. I think that inflatables are some of the most exciting crewed space technology being developed at the moment. I had only heard about Bigelow until it closed up shop and was then delighted, after a bit of internet searching, to discover that Sierra Space is doing a great job of keeping the technology moving forward (inflatables in general, I'm not trying to imply that Sierra Space's work is derived from Bigelow's ex-NASA technology but rather a different realisation of the same general concept) I'm guessing (hoping) that pressure testing is only one of the things being tested. I think I did read somewhere (but maybe I'm wrong) someone at Sierra Space saying that it had also conducted ballistic tests on the material - firing projectiles designed to simulate various micro-meteorite impacts at test samples. Some real-life test data on that might help convince some of the naysayers. The third category of test I think would be interesting is radiation testing - an initially sub-scale test article exposed to various types of radiation with sensors inside it to be able to determine the attenuation properties of a LIFE module. I know that Sierra Space has discussed micro-meteorite and radiation protection properties of its material - in both cases expected to be better than typical thickness solid station material I think I remember hearing - but nothing makes the point better than actual test data.

@@julianfp1952 Rest assured that there will be loads of test data before these go up with a crew. The ultimate burst testing and creep-burst testing are designed to characterize the "restraint layer" - the structural part of the shell. Individual straps have been load and creep tested as well, which helped inform the design of the integrated restraint layer. There is also damage tolerance testing of the restraint straps, as well as space environment exposure testing at the ISS and on the X-37B. However, the restraint layer is kind of in the middle of the layer stack-up. The outermost layers protects the restraint layer against thermal cycling, atomic oxygen erosion, and debris strikes. The innermost layer protects the air barrier from damage from inside the vehicle (crew/cargo). The air barrier itself is multiple layers to provide redundancy. Ultimately there will be uncrewed flight articles to verify all components work together as expected before we risk crew inside. As for radiation, we have data from BEAM and from earlier Bigelow standalone flights, as well as the material testing I mentioned above. LEO radiation environment is well characterized from decades of data on the ISS. There will be multiple LIFE modules in LEO before any are sent beyond, so there will be even better data on the radiation attenuation of the system by then.

@@jamesowens7176 Thank you for the very informative reply. It’s so great to see this technology moving forwards. Once this stuff is human rated it will be a huge step up from having to live in relatively small tin cans either in space stations or for longer duration deeper space travel.

Was about to say! Even Jessie Anderson was awestruck!

Gave me goosebumps

Yeah I watched that too. First how it was on its side (the "dog leg maneuver"?) gliding through the air. Then flip over. I would like to call that clip "how it looks if you ever weere about to get an orbital class rocket booster land on your head" 😂

Congratulations!👏 This is why I love this channel..

Pretty much a dream job :) Congratulations!

You should have 300 likes and a bunch of comments by now. I'm quite happy to spam tf out of this thread in compensation if required 😂

Very exciting, congratulations.

This comment is underrated, bravo

The space industry is all about redundancy. If one standard doesn't work, there are multiple backup ones to adhere to.

Well, there’s one specification for crewed docking (IDSS), and any company can build one and get it certified by their ‘local’ ISS partner agency. The Common Berthing Mechanism has also becom e something of an impromptu standard for berthing larger modules, as on Axiom and Gravitics designs, though IDSS is supposed to work for that as well. This is for unmanned probe to probe docking, picoport to IDSS’s clamp-o-tron

And the IDSS is compatible with a couple docking adapters. That is probably the best way to make a universal standard. Everyone can implement it how they prefer, but they have to adhere to the common standard. The russian APAS-95 can be converted to it (and already looks very similar) using the International Docking Adapter to turn it into the passive side, NASA has their NASA Docking System, ESA usies the International Berthing and Docking Mechanism, SpaceX has their adapter, even the chinese have a possibly compatible system.

Yes, each and every company doing space research and development has a "Department of Redundancy Department"! LOL ;D@@2ndfloorsongs

@@HappyBeezerStudios Russia doesn't use APAS-95 tho, they stuck to probe-and-cone.

Yet it could not stand up

oh my god I love it

Take your coat and get out, both of you.

Are you saying the sunlight was finally able to go round the outside?

It was a slim chance, but they did it; hopefully!! :D

But this is interesting, it's another milestone in moving away from needing people with intense piloting backgrounds to control a spacecraft. Dragon can make a complete flight autonomously, with the commander or pilot only monitoring the systems and maneuvers. Even manual control is simple touch buttons on a touchscreen. Excellent situational awareness and coolness under pressure are still needed in case things start to go wrong, but that doesn't always require a deep background in high-performance aircraft.

@@donjones4719The reason for selecting experienced test pilots as spacecraft pilots is, by definition, they are cool under pressure and high acceleration (or otherwise they get the title “the late”). Being able to fly aircraft has always been irrelevant.

@@allangibson8494 Being cool under pressure when it really counts is why Jared Isaacman takes his non-pilot crew members on flights in jet fighter trainers. It's a good point - but coolness under pressure can be gained otherwise. Zena's experience of 3 prior spaceflights must have qualified her.

Especially when a bad state actor like Iran gets a congratulations

It takes a lot of work just to make a good video about an opal. Scott has to do so much more research for his videos.

After the JW "Forever Launching In A Few Years From Now Since The 90's" ST is finally out there, generating incredible images and tons of science, apparently anything is possible!

Back in the early 90's I had a girlfriend named Lisa; she had a pretty nice "array" too!! ;D LOL

Maybe Starlinks Laser network would be able to detect fluctuations in the Earths Gravitational Well?

I was there in 2007, visiting, had some nice pints, in nice pubs, served by nice barmen!! :D

If we go to Mars and pick it up, it deserves to be fixed with new blades and other hardware.

Let’s just hope it’s not buried in the dunes by then!

They may try that once the sun comes back up. If it wakes up again that is. They probably want to wring all the usability they can in this configuration before they roll the dice on that maneuver.

This obviously a Ziz plot.

Had the exact same reaction, especially after Ward.

It better not start singing >.>

Is this a book?

@@AthosRacno; it’s an original web fiction where humans start getting superpowers in 1982 coincident with the arrival a mysterious golden man whose powers surpass everyone else’s. The story follows a fifteen year old girl who gains powers in horrible circumstances as she integrates into the superhuman society, fights the occasional kaiju, and eventually finds out the true purpose of the powers themselves. It’s an “it can always get worse” grim and gritty world, allegedly for the sake of “realism” according to the author.

Much like the military, space projects have a better chance to get funded if they have cool acronyms that are easy for government officials (or whomever) to pronounce. It's only "gravitational-wave" with a hyphen because nobody would pay billions for LIGWO. Same applies to LISA... it's easier to sell to the people with the deep pockets than LIGOSA or LISAGO, which gets even clunkier with the W in the way.

That's were the free floating gold cubes come into play. 14:37 They try to hold the satellite steady and measure any deviation relative to the cubes. What I don't understand is how they sync them. Any external signal will have a different runtime to one of the three satellites.

@@benjaminhanke79 exactly, you would probably be able to compensate for any deviation, but you would need to know the EXACT position of the satellites to the micrometer. I really want to learn how they plan to pull that off. there has to be some cleaver algorithm or something like it.

@@danilooliveira6580 I don't know. I learned about this "cube thing" in a podcast when LISA pathfinder was about to launch maybe ten years ago.

Basically the satellites shield the proof masses from any disturbances except for gravity. Gravitational accelerations are known well enough, so you can very accurately predict the path of the proof masses and thus the distance between them, while the satellites around them get disturbed, measure that against the proof masses in perfect free fall and compensate for that.

@@danilooliveira6580The satellites sync position to an accuracy of 9picometers per Hz at 3Hz using laser interferometry.

Yup, maybe LOL. :D But Sky Lab was a kick to watch on TV, when it launched, on a Saturn V, in the 1970's; it was huge inside!! "Back to the future" anyone!? LOL ;D

Yes, but best to "fly lucky". I did that years ago, when working as a field biologist for a state conservation agency. Did many flights, over 30 years, to observe animal populations from the air, collect data, and do research. I was not the pilot, but our great pilots would sometimes, jokingly say, as we taxied back to the hangar after a flight: "Well, Ron, we cheated death, one more time"! LOL ;D

@@ronschlorff7089 Thanks for the input.

thanks too, BTW, whenever I see a plane in the sky, especially the medical helicopters which fly over my house often going to a nearby hospital, I say a little prayer for them: "God bless you and keep you safe" Sort of like your kind saying to Mr. Scotty here!! : )@@General12th

I suspect that the payload bay will be a work in progress. They need to get the vehicle flying first. I'm expecting some kind of clamshell not terribly unlike what Rocketlab Neutron has been showing in renders, will be the ultimate version. But that is just mechanical/structural engineering. That can be dealt with once they get the flight dynamics sorted.

Hype? All he did was inform.
