Great video!!!! One of the reasons the MMU was doomed was the fact that the orbiters were more maneuverable and held their attitudes better than anticipated. That's why the crew of DISCOVERY's STS-51A mission used the MMU in November 1984 when rescuing the stranded Palapa B2 and Westar 6 satellites, while her STS-51I crew didn't when retrieving/repairing the equally stranded SYNCOM IV-3 satellite in August of 1985. That, plus the loss of CHALLENGER, ended the MMU.
@Bobb Grimley It is not me asking about behind the scenes; it is *66kbm,* so it is for him/her to investigate. I have already seen the episodes from behind the scenes, and other non-space stuff.
Al Bean, what a dude. I've only got a sense of his career from "From the Earth to the Moon" but now I want to know more. Thanks Amy, entertaining and informative as always.
i was beginning to think, you were all done with your videos. everything i saw on YT was from 3 to 5 years old... i so absolutely love your little corner of the internet!
Thank you for this video... The system they used was clunky and primitive. If a suit-level maneuvering system will be used one day, it should be miniaturised and fully computerised, with its own gyroscopes, able to dynamically keep stable attitude, and controlled - possibly - with both eye movements and a classic joystick. The human ability to stand in equilibrium uses the eyes and the ear vestibules jointly; in absence of weight, it can only rely on the sense of sight, which is badly impaired from inside a space suit. Again, thanks for your dedication to all things Space...
Goes to show that more often then not the great idea is the first little step, it is diligence, tenacity and dedication to make it work, that turns it into an achievement. ;-)
Whew! I was worried about a number of things lately. The number of post's from you and Pete sightings. I can see your still able to bring us more interesting stuff from the past, you're okay, Pete's okay, we're okay. Thank you, stay safe.

Great content, as always. I would love to see more videos about solving problems regarding astronaut movement while in open space. Also, I would love to see more videos you make, they are informative and they incite me to do some more research on the subject. Sorry for my english, not a native speaker.
Re: SPACE CATS I once saw a video of the very first NASA parabolic flights - for the astronauts to experience the lack of gravity, and they had some cats onboard. It was in plain to see how the cats highly disliked the experience...
@@antoniomaglione4101 That's one of the things Robert Heinlein got wrong: in his books cats are described as having a natural affinity for weightless environments. Maybe with lots of acclimation time they would be, but if not it'd be miserable for the poor creatures trying.
In my brief (but highly memorable) time playing the tabletop role-playing game Paranoia, one of the gadgets I remember being available to players' characters were "Rocket Boots". While, at first glance, incredibly useful, they (like so many gadgets featured in the game) had a significant issue. In this case, the need for the player using them to perform regular (as determined by the game master 😁) dice rolls against the character's dexterity ability in order to ensure that two separate rockets of considerable power stayed pointed in the same direction while firmly attached to the character's legs...
I think I'd want the jets as close as possible to my center of gravity rather than on my feet. I don't seem to have any memory of this tech from the days it was being tested so thank you the info :)
For six degrees of freedom, I agree about the center of gravity. If you only need to send thrust down like a rocket you can probably balance your center of gravity over it, but if you need to move toward something you're facing you need the thrust behind your back. Either that or you need to be able to rotate in space to point your feet in the right direction. Bending your knees at right angles to send thrust behind you is just going to make you spin end over end.
Hi Amy. Great story but now I’m curious about how the jet pack came about and its operational use. Perhaps that could be the topic for your next video. Thanks for sharing.
Not related to jet shoes but I hope you’ve seen the Wright Patterson AFB Museum Jacqueline Cochran displays. They had several story boards throughout the museum documenting her career and life.
I remember a early gemini flight that was going to test this in space. The space walking astronaut was unable to get to the rear of the ship where it was stored.
That was Gene Cernan on Gemini 9A. They didn't think to build hand-holds or rails for him to get back to the instrument section, and between that and the stiffness of his spacesuit he became exhausted, to the point that his faceplate fogged up, blinding him. The command pilot of the mission Tom Stafford told Cernan to abort the effort and to return to the capsule.
Very interesting. If anyone remembers the TV series “The Greatest American Hero” with the actor William Katt. His attempts to fly as well as Superman made me visualize these astronauts trying to maneuver in space. Not very well.
White said it worked fine, but he quickly ran out of propellant. There was another model of the unit with the propellant supplied from a back-pack unit on Gemini 8, but it was never used due to the mission being aborted after docking with the Agena Target Vehicle. On Gemini 10 Mike Collins used a version that received its nitrogen gas propellant from inside the spacecraft, through a hose bundled with the astronaut's umbilical connector. Collins successfully used it to move back and forth between the Gemini and the Agena Target Vehicle.
It all sounds a little bit dangerous with the potential to have a very bad day out in space somehow eventually - thank you Amy - never heard of this before - 🛸👽
@@akira4085 - it just sounds silly and unnecessary - they had the hand gun in Gemini and then had a full backpack unit on the shuttle - jet running shoes in space is out of a kids cartoon
Thrusters are really most effective directed on the centre of mass, otherwise they are more like rotators. So that sort of works as long as you thrust along the vertical axis of the body. You would be best to actually pivot to a horizontal position to move sideways. So you could do that with rotation wheels on you or RCS. Probably an easier way instead of feet would be a 3 axis RCS around the upper torso...
Cat-tails. I can't make a salad, take an indoor picture, read a book, watch Vintage Space, or do my morning routine in the bathroom with cat-tails in my face.
Hey. In a similar vein, when I was a kid, I had a pre skylab book about space stations, it had odd tools depicted. A space hammer. And various plier type tools that worked on a scissor type fashion Any idea where those ideas came from The book described how regular tools would work in space
Why did they not test it in a pool where they could have tested all dimensions? Obviously they'd have to overcome buoyancy but I would have thought it could be possible
My guess is the mass of the surrounding water would require a lot more thrust to push it out of the way as you move through it. That would mean higher air pressure, bulkier tanks, and bigger valves.
She said "jet shoes" and I said Bless you!
Hahaha
That was an awful pun.
I enjoyed it thoroughly.
She said _"a boot"_ and for a brief second I thought she said _"about"._

Always pleased to see a Pete appearance. :)
Now visions of astronauts gliding in space to KC & the Sunshine Band’s “Boogie Shoes” is in my head.
Seriously, great find & great knowledge, Amy!
I don't remember whether Commander Lewis had that song in her music collection. 🙂
Love seeing the vintage video clips. Thanks.
Jet shoes for space its "very much wow" as a topic of a talk for vintage space.. getting proper means and small details like these are priceless
That’s amazing, never heard about this before, thanks so much for another great episode ❗️
Very cool. I had no idea they tested this idea on Skylab 3. Had to watch a couple of times.
I just saw jet shoes in space by the vintage space and I’m like “I’m watching that first” lol
Came for the jet shoes. Stayed for the kitty!
Bruce Mcandles was a capcom for Apollo 11 and you can hear him on launch and the EVA when he says okay neil we can see you coming down the ladder now!
How about a "Behind the scenes" episode showing cameras, set up, lighting, filming and of course...Pete. We love Pete as well.
There is a "behind the scenes" episode already.

Ok now we need a video on the mmu, which unfortunately is old enough to be considered vintage now. 🥲
I can just imagine Neil Armstrong wondering "How is NASA trying to kill me Today?"

Dear Amy,
I want to thank you for your great work.
You are a real space-powerhouse !
All the best from Germany
It's near midnight, and I really should head to bed. See Amy has a video titled "Space-Walking in Rocket Shoes", and suddenly sleep can wait.
Awesome! I never knew of the test on Skylab. As always, Amy…very interesting and very well done! Keep ‘em coming!
Yay Pete returns!
And the truth comes out: Pete is really a ventriloquist.
Great job, considering he has no opposable thumbs.
Fun! I'm always impressed with the variety of ideas they came up with during the Gemini program where we really learned astronautics.
Go Pete. Great to see you guys. Love the great information.
Thanks Amy, never heard this story before.
Very interesting and worthwhile video. I would guess these are rather obscure and rare video clips.
Great video I had never heard of this system.
And you look great as always

Ed White's unit worked just fine. Don't know why they didn't continue with it when Gene Cernan was nearly killed on Gemini 9 trying to get to his AMU.
