The video does get something wrong, when it talks about the “maximum speed” of the different versions. It’s probably done to try and simplify what the number actually means, and I know that’s tough, but in this case I really think it got oversimplified to the point that it ends up actually wrong. The numbers they give are actually the “Delta V” the MMU/ASU etc had, with delta meaning change and V being Velocity. There isn’t really a “maximum speed” for anything in space (not counting the speed of light) because there’s no external force like drag to slow it down, so DeltaV is convenient way to measure the total potential energy in the remaining propellant that could be used to accelerate a spacecraft. Instead of general units of energy like joules it’s given in a more useful form- the amount of velocity change you’d get from using that stored energy to accelerate the total mass of the spacecraft (in this case the Astronaut, suit and maneuvering system) in one direction. It’s true that if you start at 0 velocity (relative to some other object) and accelerate in exactly one direction you’d run out of propellant just as you get to the numbers given, but DeltaV tells the total energy available for any acceleration- rotating, slowing down, changing your direction (accelerating to the side). It’s directly useful to immediately know something like “I’m approaching the other spacecraft at 20 m/s, I will need to use 20 m/s worth of DeltaV from my fuel tanks to slow down”. Just quoting it as a “maximum speed” suggests like they can accelerate up to that speed repeatedly, slow down/maneuver around for some period of in a way that’s a bit like saying a car has “100 mikes per hour” worth of fuel (not a perfect analogy, space is complicated, but it’s misleading in similar ways).
Not a big deal, and some might think it’s nitpicking, just seemed worth at least mentioning here! It’s the kind of thing that won’t effect the most casual watcher, and space nerds will know what you mean (but also wouldn’t need the simplification), but misleading for the mid ground of someone interested enough to find the details interesting but without the background to know it doesn’t really mean that.
My dad was one of the engineers who designed the MMU, and trained McCandless on the simulator. He was always proud of his work on this project, and would have loved this video.
@@darinfoat8410 Oh WOW he was also involved in Voyager!! That's pretty much my favourite thing that humanity has ever created.. and they both launched years before I was born. Incredible. What a guy Chet was, you must be immensely proud. And I know it's been over a year but still, sorry for your loss. My gf lost her dad two years ago (on the night we met, actually) and I know that these are still early days for both of you. I hope you are dealing ok. PS. Lookin good for 54 sir!
This is one of my all-time favorite photos from NASA. I can't imagine what it was like for McCandless to be in his spaceship for one on orbit. The view had to be magnificent but tinged with the fear that something might go wrong with the MMU. The Right Stuff indeed.
I’m not sure astronauts are actually capable of feeling fear. Not because of some superhuman trait of character, just because of their incredible professionalism and extensive training, compounded with above average levels of intelligence and self discipline
Udvar Hazy is also where the shuttle Discovery is on display. We live close by, and it is an excellent museum! If you are ever in the DC area, you can actually get there via a shuttle bus from the Air and Space museum on the National Mall as well as by driving.
I was in US Air Force ROTC in college when in January 1967 we were flying from Floyd Bennett Field, NYC to Andrew's AFB for a trip in training and our landing was delayed by the plane carrying the three brave dead Astronauts from the Apollo 1 Fire 🔥. Tragic to say the least. We were really glad 😊 to visit the KSC in Jan. 2023 while in Florida. Very exciting to see launces while staying nearby on Merritt Island. 😊
That was the most horrible of the accidents in my mind because they were so close yet still nobody could help them. Forever remember that day, and never forget the lessons. Safety rules are written in blood.
Although the brain would tell me that the laws of physics hadn't been repealed, my eyes would tell me that the second I let go of the ship, I would plummet, hurtling toward the unavoidable fate of atmospheric re-entry.
The Soviet cosmonaut, Alexi Leonov, showed great skill and ingenuity in dealing with his spaceship reentry problem with his bloated spacesuit. Much respect to him.
Absolutely terrifying. The respect I have for astronauts is quite literally astronomical. There is no way in hell I’d go up there, much less leave the spacecraft.
What I find amazing is he is getting out of a spaceship that is orbiting at a million miles an hour though they don’t feel it and they then can not get left where they got out as the spaceship flies off on its orbit ,
I was literally thinking about how astronauts are technically traveling at ridiculous speeds with little more than a space suit. Took me a minute to realize the lack of gravity is the only reason their bodies weren't ripped apart.
It's the same reason you can step out of your seat in an airplane traveling 500 mph and not immediately get slammed into the back of the plane: inertia
@@olanmills64 but if you jump out an aircraft skydiving you do drop pretty fast ? Does the lack of gravity let you stay on the orbits speed as your mass is already moving relative to the spaceship . I know there’s lot of maths and science behind why you stay relative to the space ship but I assumed your lesser mass meant you’d slow much quicker than the larger vessel you climb out of. Haha . I’ll stick to repairing guitars . Space flight is above my pay grade haha
@Johnnybananass-_ there is nothing to make you slow down. Air resistance isn't a thing in a vacuum. When you jump out of an airplane, you start out traveling forward just as fast as the airplane is going, but since that speed is less than orbital speed, you also fall toward earth. In orbit, you and the spacecraft are also falling, but the curve of your fall is equal to the curve of the earth, so you fall around the planet instead of toward it.
@@QBCPerdition thanks for that explanation, i think i can picture and understand that. always great to be 50 and still learn new stuff about the world around me
Gene got to play with all the cool stuff! First jet pack, last guy to walk on the moon, and he got to drive the lunar rover several miles! And he got to be on a Daft Punk track.
This is gonna sound ridiculous, i know my hearing is terrible and I'm sure I'm crazy, buuut.... Does the audio have a slight echo? It's almost like being on the phone with someone, when they walk into a restroom..
Yes it does, but that's nothing new with Simon's channels. I personally don't mind it and actually prefer it over the shows where they get right up into the mic - so as you might imagine it's because he is further away than a lot of others and because of that the mic also captures the ambience of his voice as it bounces around the objects in his studio.
The AMU team definitely had a pair, sending a hydrogen peroxide-fueled unit into orbit. It was probably for the best that this particular design didn't see use by an astronaut, as an HTP/catalyst fuel system can explode violently if something goes wrong. That one didn't go off in an accident during launch was probably down to equal parts good engineering practices and luck. HTP explosions actually happened on the ground, including the event which (probably) sunk the Kursk in 2000.
McCandless II, Selected for these missions due to his humungous testicles! Unethered EVA's? They had the very best equipment our Western World could concieve and then create. Heros? Absolutely.
There is just something absolutely terrifying about knowing you are completely un tethered, a slight push and you will keep that speed nothing will slow you down, no one is coming to save you, and the only thing that is capable of taking you back to the space craft is a jet pack built by someone that might have argued with his wife before work or been tired that day and forgot to do something important 😂 floating through space probably spinning from your frantic attempts to stop knowing that you are going to continue that way until you hit something or suffocate from running out of gas, absolutely terrifying to me, there is no painless way out either, opening your suit could be much worse, I would hope that CO2 builds up putting me to sleep rather than running out of oxygen, but it wouldn't happen like that the CO2 scrubber would greatly outlast the oxygen supply 😢
I need to learn more about the Challenger disaster because on the surface, with just the bare minimum info, it kinda looks like somone grabbed at the first excuse they had to cut founding to NASA.
The reason strong alcohol makes you feel warmer is because it causes the blood vessels to expand. Increased blood flow means the skin becomes flushed. This in turn means you radiate more heat into the environment and less blood is moving through your core.
The MMU's lack feasibility and practicality could have easily been foreseen if space exploration's judgment wasn't clouded by the influence of science fiction.
I could legitimately watch this footage all day. I feel so sad for the people who gaslight themselves, or are gaslit by some arcane version of some religion, into thinking space isn't real. Reality is so much cooler.
when your space suit becomes too bloated to fit into the airlock, your space suit becomes the airlock and you must hold your breath for longer than comfortable.
The Voshkod was based on the one-man Vostok,. It had the same capsule-size. It was a tin-can that was originally designed to hold only one person. Only for a quick propaganda victory they pressed two people in there. A rush job with enormous risks, like so many in Russian Space Flight.
People really don't seem to understand that if an astronaut starts floating away from the ship untethered it would be really easy to maneuver the ship to intercept them. Spaceships always have spare fuel and don't require a lot of it to do small corrections
@@MichaelWinter-ss6lx Easy for trained professionals you dummy, your nay-saying isn't gonna prevent it from being the truth.

SpaceX is doing what the German rocket team wanted 80 years ago. Or what NASA should have done in the '70s. There should be a real space economy by 2050.
o horrible though. imaging just working on ur ship and for whatever reason now u drifting away in nothingness. getting farther and farther until u all alone .
Not only does weight/mass require more expensive to get up into space, it also requires more energy to move it and change direction and stuff, not to mention accommodating its size in cargo areas, being able to unload it safely in space, then load it back and secure it later etc
So are we still talking about The US Had humans on Moon and now with all the technology we can't land a robot the size of a dishwasher on moon??? Just food for thought 😂
I feel the same about imperial - though I've mostly gotten a hung of rough estimates and can speak using that now if need be. Imperial is just straight up nonsense when it comes to mathematical conversions between units, especially between volume and mass. Everything is some kinda division by 1, 10, 100 and so one, and then just prepend the latin designation for it. Deciliter is 1/10 of a liter, for example. a kilometer is 1000 (kilo) meters. It's not all butterflies and sunshine, but it beats the alternative. I'm sure you've heard this a million times, though, and it obviously doesn't change what you're familiar with and how you feel, just thought I'd share my sentiment - it's a comment section after all.
Metric is good for some things and imperial is good for other things. In the uk we do actually use both. Miles for distance, pints for beers etc Personally i use Fahrenheit during the summer and centigrade during the winter. Feet and inches for height, millimetres for small distance measurement. Stone and pounds for my weight. Kilograms in the gym. Thousands of an inch for gapping points in a distributor.

You've got at least another 20 to go
June 28'th, 1986?? WTF!
Teleprompter fail, the closed captioning has it correct stating January 28th.
I wonder how they inflated the shuttles tyres? They would have had to handle enormous pressure changes.
The Shuttle's main wheels were inflated to a pressure of 23 bar. When the outside pressure changes from 1 to 0 bar, that's not a big difference.
76ms equals about 170mph. That astronaut was cruising, or at least had the capability to do so...
Challenger disaster was January 28th, 1986...not June.
Anyone else notice that he bumbled the Challenger date ???

Personally i use Fahrenheit during the summer and centigrade during the winter. Feet and inches for height, millimetres for small distance measurement. Stone and pounds for my weight. Kilograms in the gym.
Thousands of an inch for gapping points in a distributor.
