There's a single person spacecraft being designed to go with the Orbital Reef. That's probably going to have more utility and be safer than something that straps on to a space suit. Will it get built for Orbital Reef? Hopefully. Will somebody eventually do something like this even if this doesn't pan out? I think it's inevitable.
Coulda used it for I'll fated Columbia's last flight to check beneath the orbiteŕ.
It's Eerie as hell seeing the astronaut floating so far away from the space station. Makes my heart race just thinking about their perspective.
💯💯💯
Yh absolutely terrifying
That astronaut said he focused on the space shuttle the whole time he was floating with the jet pack. Can't imagine what its like to just see deep space and darkness all around while floating. Knowing a malfunction of your jetpack could be end of your life.
But the shuttle could be maneuvered to pick him up
That one image of Bruce McCandless II floating isolated in space with a jetpack is the single most iconic picture taken from space full stop. Even the moon landing doesn't have such a recognizable photo.
💯💯💯
Actually, the 'single most iconic picture taken from space', which includes the Apollo moon landings, is of course the photo of Buzz Aldrin that was taken by Neil Armstrong during the Apollo 11 mission in 1969.

Excellent video but "most dangerous spacewalk"? Come on, I don't think it's even close. There have been a couple of spacewalks that involved fluid leaks. One of them involved an alarmingly large ball of water forming around the astronaut's head and he was actually at risk of drowning.
So I've seen a documentary about this, and they really dramatized it. I know this sounds gross, i was thinking, could have swallowed the water, and continue the mission.
Here they are completely loose as well though, a couple malfunctions or slips of the thrust and the astronaut could be sent into an un controllable tumble.
I remeber what one
@@johnrymszewicz Another thing you can do is open a valve on the suit into the vaccum of space, which can suck out the fluid
He needs to make you click on his videos somehow
What jetpack disaster? Seems like the jetpack worked just fine.
Clickbait video
clickbait thumbnail 😂😂 I also fooled by thumbnail, I knew everything worked fine spacewalk
It wasn’t Robert Stewart who flew 100m from the Challenger Shuttle, it was Bruce McCanless
exactly 💯
They probably have a future (well, maybe). But I'd say it's @ the most uncharacteristic risk undertaken. It's wonderful to have the testing. Not to mention, how fun?! But considering they won't turn a screw unless absolutely essential (and agreed upon by committe!), it's amazing they allowed this.
Enter SpaceX.
Just say at
@@calibranese did you mean "it"? Over time I've occasionally received a few "your words make no sense" after thinking I wrote something straightforward. Then look back to see whether thru impatience or punctuation, etc., my elementary writing skills would be more helpful! But this time I just can't seem to find what jumped out to you.
One guess is that I'm trying to point out the unnecessary bureaucracy caused by a gov't program. It's true I am one of those guys, but wasn't really going for that here. It's obviously not the biggest deal, but since I have the time at the moment, I'm just curious if you recall what you meant. Take it easy.
@@SuperPhunThyme9 not sure if you're trying to have fun, waiting to hear back something like "And what exactly is that supposed to mean/Growl"?! But you'll get no argument here. I even think there's an adult argument to have when it comes to our biggest committee & the influences within it. Namely all three branches of gov't! Ironically the taboo/effectively forbidden nature of that debate comes from...3 guesses???
Even though my argument is All biological, and Zero ideological, good luck trying to get anyone to hear that once the topic is merely mentioned. Forbidding the discussion of potentially important issues, hmm, also feels familiar. ;)
All I know is you don't need to be a warhawk to understand the importance of power projection/perception. As I write this it takes no mental effort understanding that China views Thailand, Putin the Ukraine, and the Taliban Afghanistan, very differently now & almost overnight. Is it "because" of women? No. But it IS due to believing the world will suddenly behave the way you want it to. Will/can men screw things up? Every time. But why offer extra wins to your adversaries in between those moments.
Thank you, that was actually a fun diversion to start the day. I hope whoever you are my thoughts were taken as offered, just as interesting stuff to discuss. Instead of as another one of those new fantasy worldviews, which is that my words are themselves actions, and/or "dangerous"!
Take it easy, have a good one.
Thank you for these videos! They are sooo helpful!
Another good video, Primal Space!
Excellent video i was casually surfing about space suits and hence another great UA-cam suggestion..........great content....
So amazing, yet so frightening!
I didn't know spacewalking existed until I played a VR astronaut simulation.
It was my curiosity that brought me here. Seeing spacewalking on video is breathtaking but also chilling. It was frightening to walk in VR.
I love when I find a new space channel!! I’m also a fan of SEA, V101, Kosmo, John Michael Godier, Event Horizon, ParallaxNick, PBS Spacetime and more. Any other recommendations?
History of the Universe
i remember the first american astronaut in space that did the first crossbow space walk.. man he really got sad when huston canceled it :/
imagine what mission control thought when they heard that he broke his microphone
Talk about a stressful work environment! 😱
I love these documentaries
they could have had a long tether attatched while doing the space walk so if the pack fails they still have a way to get back
they can also pull on the tether hard to bring them close to the craft fast if the comms falls loose or ice buidup
im js
I was playing a vr iss game and I accidentally started floating away from the station, couldn’t imagine that but it was real but at least they had the jets
Wow I had no idea about this!
Free maneuver in space is probably always gonna be less than ideal but as a working class of people used to performing extravehicular tasks emerges I'd guess we'd see more people with innate skill at free maneuvering. It would probably also be possible to use computer aided control.
All I know is fully manual, 6-degrees-of-freedom spaceflight is a bitch.
Kerbal space program will give you an idea of it lol. I guess barring some malfunction that's throws you wildly off course or space debris, it's not as dangerous as it seems.
i would be terrified if i was over the earth and the jetpack just stopped
happy Halloween to all
Wow!
it was Bruce McCandless who flew 98m from the Challenger Space Shuttle
DC or other space museums are must trip to all middle school to high school students of world , expenses to be picked up by Governments, its not only very enlightening, fascinating and strangely real to see up close personal what is so far only on television visuals, and brings home the point of infinite intelligence and reach of human minds, but along with that do not forget civil social responsibilities of looking after all human lives which also has far more important value to nurture nourish lives which might have suffred from neglect because of these issues overlooked in their lives.
Miss the MMU.
I cant belive they made space jet packs and not normal jet packs :(
Hmm… how about pods, like the Discovery had in 2001?
ok good work
He's in the water
2:40 i dont speak feet per galons
This makes me sad
"Tether or no dice" would be my policy. Preferably two tethers. In fact, I'll just stay here.
Oh please, we all know who's the guy with the first successful airplane, Santos Dumont
Did air horn and electric horn work in space
Quick Tip: If the used knickers you've been using to sniff have started to lose the smell, just lightly steam over a freshly boiled kettle to reactivate the scent
"The jetpack was considered to be an unnecessary risk" That really illustrates the state of mind that NASA is still struggling to free itself from.
NASA is government… incompetent, lazy, irresponsible, uncaring… Government NEVER cares about results… only increasing it’s budget.
Untethered it is, really easy for something to happen and the astronaut could be launched away from the craft
They were getting much better with the arm based EVAs, and the MMU is both considerably more risky and in many ways less capable. On the arm an astronaut can apply pressure with both their arms without burning through propellant. The MMU had a total delta v of only around 25m/s. That's fine if you are just pottering around at a fraction of a m/s relative to your base, but you are going to have to anchor somewhere to do any real work. The torque from tightening a nut takes a surprising amount of propellant to counter. To do many jobs from the MMU the astronaut must also anchor themselves somehow, while on an arm they would not. It's easy to focus on the "risk" part of it, but the decision was probably more to do with the "unnecessary" part. It just isn't a good solution to the problems it was meant for, cool though it is.
That's before you even consider that they were also hoping to move into stations. The shuttle made it far less risky, having a good RCS system of it's own. Worst case scenario and the MMU failed completely the plan was to manoeuvre the whole shuttle to get them into the cargo bay, close the doors, and then recover them with no risk of them bouncing off. You can't do that with a station.
@@agsystems8220 Valid points. Though, do astronauts always use the arm to service the station? My understanding is that they often transit manually. The MMU would be good for that. Do station EVAs involving torque always have the arm in use?
Could the MMU have helped save the Columbia if they had it onboard? Why does this always seem to be brushed under the rug?
It’s not powerful enough to do anything on earth, it can only do small movements in space. You cannot use the mmu as a portable rocket on earth
Earth gravity is 9.8 m/s² and mmu can only accelerate at 0.1 m/s²
@@confusedtoad8757 I meant that the MMU could have been used to directly inspect the damage and as a platform to place objects into the hole in order for the orbiter to survive reentry. They didn't even get a close-up shot in the end. Best they had was a long distance shot from a spy satellite. If I was on that flight you better believe I would have wanted to see that hole up close and do something about it.
@@smithtorreysmith it was an organizational failure. NASA risked their lives and in the end lost the bet. They could have explored other options and they underestimated the damage.
is betterhelp still contraversial?
It's so sad that this vehicle has been put by the wayside. Thanks for another great video!

"Disastrous"?
A science channel that doesn’t include metric units?
Just learn imperial.

Oh, thanks America for the psi, the rest of the word use bar
What jetpack disaster? Clickbait title.
why not just say 300 bars?
This is truly what George Orwell predicted
Perhaps you're getting confused with Arthur C Clarke?
Santos Dumont invented the plane,with an catapult even shit can fly
The Wright brothers flew without the catapult before Dumont even got his first plane flying. It’s common knowledge
@@fileoffish1403 you have proof?
Was it recorded like Santos Dumont first flight on the 14 bis?
I Wonder how spacex’s space Jetpack will look like
Not a match to NASA.
They aren’t developing one?
Not using the Space Jetpack sure saves NASA a lot of money. Will we use it again in the future? Who knows. Probably for emergency uses.
Sure guarantee's NASA to get shut down also but hey, let these bums stay scared. Jetpack is the best idea and the reason it's not used is b.c these astronaut's don't go out in space like they legit had to back in the day
Was Biden demonstrating how to use the jet pack during that interview?
"I need TP for my Bunghole."

@@nPcDrone Biden is your president now and you're going to accept that fact lol - trump was the last conservative president that you'll ever see in your life.
Please give metric conversions when not using the metric values. I don't know what a psi is. We have pascal or bar. Thank you.
That's not necessary on American social media.
@@ChadwickTheChad UA-cam has a global audience, putting the metric number in the corner helps other people understand the video
@@apollo8030 The global audience should obviously learn the imperial system.
@@ChadwickTheChad is this satire
I feel like there may be a future with jetpacks and Ion thrusters. Instead of pressurize tanks and diminishing thrust you’d just need a battery
Wow what a clickbait

What part of the spacewalk was "disastrous?". Come on, enough with the clickbair
Why does every freaking documentary about aviation or space start off by reminding us about the wright brothers. STOP mentioning it. WE KNOW ALREADY. It's adds absolutely nothing to the content of the video. It's just filler, get rid of that boilerplate from now on
clickbait title,,,dont watch
