A yes the good old emergency fuel reserve. Nothing beats the experience of getting out and pushing your capsule back to kerbin.

@@peter4210 sometimes rinse and repeat 18 times before you finally de-orbit from the distance of Minmus

@@jip5889 I love making the kerbin landing part 20k worth with a cargo module filled with science parts and extra RCS fuel. It also hides the solar pannel but It makes it hella heavy so after making 1 mun hop too many to get some extra biome science, I did have to rince and repeat for 10-20 min real life to get the periaps down into kerbin

I rescued a Kerbal in a krakened station one time thanks to the EVA pack. Station exploded and the module the Kerbal was in was spinning. Got out, corrected for spin, then burned to the nearest spacecraft that was about half an orbit away at that point. Just barely made it with single digits in the fuel left but that Kerbal lived to fly another day. Until he got stranded on the Mun in a later mission.

@@peter4210 Although you do need to be careful to not put your spacecraft in a spin, those are rather hard to correct by pushing...

It's ok as long as they don't have an equipment malfunction at the wrong time. [Murphy's law] Yea, if something goes wrong and there is no means to get you back, you're screwed. I wonder if you're in that situation and you begin to run out of oxygen...Would there be a way to self terminate instead of slow suffocation? Maybe it wouldn't be that bad of a way to die as hypoxia sets in, you know it's coming quick but you get delirious first and then fade away into unconsciousness? [Take off the suit helmet and make it real quick.]

Fly safe, indeed!

That is so cool.

Is having a pair of stainless steel pants not normal for some reason?...

6:47 !!

Or, possibly so they can say, "kiss my shiny metal ass".

Or to match the tin foil hats

To protect their massive balls from space debris

Now teach him how to pronounce it!! 🤣😜🤣

@@teaurn That’s unlikely, but a good point nonetheless. If curious, you can ask Google translate to pronounce it for you: средство передвижения космонавта

@@teaurn Would take a few years, just like with Nauka ;)

First of all, i thought that spk stand for само пропулсирующий костюм

@@noop9k Yes, but Nauka doesn’t look (at least to westerners) like you threw the alphabet into the blender with an extra helping of consonants for good measure, and pressed the turbo button!. Plus I’ll wager that as a younger lad Scott watched Miyazaki’s Nausicaä or read the manga, that helped me saying it.

Yeah! Its so ambitious and im pretty sad that nothing like that is happening these days!

@@oadka we'll see what starship is able to accomplish with its payload Bay.

@@JohnSmith-yp2nt and the starship itself is literally metal

@@OriginalSeblakCeker 🤘

That is a thing only the Shuttle could do - satellite servicing and retrieval.

Anxious? Trust me if his mom found out that he was leaving the spacecraft untethered she’d throw a shoe at his head from Earth knocking him right back.

Absolutely, one of them nearly drowned recently.

@@ThatGuy-sd3zl l a c h a n c l a

Yes but would gladly do it if given the chance.

Nah, let them live a little.

I met him in high school. He came and spoke to us since he was an alumnus of ours. Really nice man. You'd be proud

Have you read the biography that his son wrote? His son was interviewed on the Interplanetary Podcast that came out mid-July. You might want to give that a listen.

Wow, now that's a conversation starter!!

i cant tell if your referencing factorio or real life, either way its funny

Now they are 3D printing AR15s on the ISS, you know, just in case of a 'home invasion'. Presumably by 'tic tac' pilots...

Praise Gun Jesus that they weren't given zip 22(s)

A quick ballpark suggests that for the Kerbal EVA pack to get its 600 m/s of delta V on just cold gas alone, the pack itself would weigh roughly 8x what the Kerbal does

Truly a remarkable vid. I expected to learn something new about EVA propulsion but this was absolutely chock full of info... And yeah, I knew Kerbals were OP but this really puts it into perspective.

Pretty sure kerbals have no understanding of the word "safety", bet their jetpacks are paper thin shells full of monopropellant.

Kerbal's EVA propellent used to be monopropellent

An engineer kerbal can use the extra fuel canister as a drop tank, essentially creating a two-stage rocket with over 900 m/s of delta-v.

Cool!

not to rag on you or your work in the slightest but the fact that your company worked only on a leg joint is why the Artemis suits are so fucked. too many cooks in the kitchen with 100 companies all making one damn thing. cograduates on being part of something so cool tho!

@@the_seeker.entity9206 we didn't design it, they sent us the blueprint and we manufactured it to spec.

@@Kumquat_Lord thanks for the clarification!

@Colin Berg Never said its doomed to fail, its just extremely over budget and late. Its not like Boeing doesn't eventually get the job done. it just steals 100s of millions from the tax payer while it's at it.

Whoa. That last point is really impressive!

Chris Hadfield/CSA have lots of good videos on this

That made that astronaut twice as lonely

@@vladimirdyuzhev In space no one can hear you whimper in sadness.

you can't see it in the picture but it is actually a picture of the biggest balls off the planet.

there was also a commercial product called Zip (Zip 22), or the P90 at home as some would call it ukposts.info/have/v-deo/kGmTiYJ4qah81Gg.html

The Russians have a sawn off shotgun on souze to shoot bears that get too curious

the zip gun could potentially be a weapon. a tube inserted into the front nozzle would suffice. and a needle-shaped projectile.

Well, the real MMU has a gyroscopic stabilization, which is expensive enough that I doubt Space Camp would have included it. But yeah, it's stability is a hard problem to solve.

@@jmr5125 Don't we have gyroscopic stabilization in our phones?

@@leerman22 Electronic gyroscopes have come down in price by several orders of magnitude since the '80s.

@@leerman22 Phones have gyroscopes with which to measure movement, but they offer no stabilization at that size and form.

@@leerman22 Gyroscopic *sensors*, yes, but I'm assuming that the Space Camp hardware is actual training hardware that actual astronauts might have used for ground training, and I'm quite confident that such an item would use a mechanical gyroscope. Also, it's in the best interests of the camp administrator to make the trainer hard to use (but not impossible). A simulator that anyone can master in 10 seconds doesn't keep the children occupied for very long, after all.

I lack any knowledge of the reference you’re trying to make. Are you saying we theorized that it was possible for us to sink into the moon upon landing? That is comical I have never heard of that :p

Booooo

@@DailyBongHits It's actually a really funny/interesting topic! It's little known, but before we landed probes on the lunar surface, we had no way of knowing the surface conditions there. There could have been an 8 foot layer of powder that would sink any lander that was set down there, for instance. A lunar rover concept even had screws for wheels, to cope with this hypothetical problem!

Some peoples think the Moon is made of plasma, rovers sinking would be the least of our problems lol

@@jacobstewart1365 Nasa does love to think that the surface of other bodies are realy soft. I'm still not over the self digging heat probe that was just a glorified dildo that never managed to dig in the martian soil when the plan was to sent it 3 m down. I am ready to bet the soviet union or college students on a budget could have made a better self digging heat probe

If I recall correctly an SSTO is a Single Stage To Orbit, and the space shuttle wasn’t that at all. I admire the idea of a SSTO, but in the meantime, a two stage rocket will do.

@@williammullins6116 Of course, edited above to fix!

Problem is its waaaay cheaper to launch new satelite than repair old one, with the few rare exceptions like Hubble orbital repairs are useless.

I just hope it doesn't do an embiggened N-1 Rocket Explosion

@@ericlotze7724 During testing/development thats fine. I just agree with Elon that it should better be clear of Stage 0

The Shuttle was really unique with its open cargo bay and spaceplane reentry (easy on the return cargo). The orbiter was also halfway ssto, since its engines came up at liftoff and remained on till orbit, but it needed the big SRBs for the orange tank

Benefits would be reach, you can get wide images, free angles and faster movement. Maybe could be used to deliver tools/spares to astronauts on EVAs. The arm is quite slow, has limited reach and takes a while to "travel" to other parts of station. Drone could be padded also to protect station from bumps. They could also use cheap replaceable gopros on this if you launched it every time via airlock to deal with CMOS degradation in radiation. Or have it 'docked' on the external side of ISS, dock would need charging port and valve to reload drone with pressurized gas (which would be an issue as you need to have high pressure plumbing in place). .... but yeah I'd love to have some 4k cool shots of ISS and other hardware. 360 camera to get some immersive vr stuff.

I really miss the originals personally. Especially the starship intro version. The new ones seem wrong to me somehow.

@@JamesUKE92 It's because the old ones had a more homemade feel, which suits this channel much better IMO.

I dunno, I kinda like the bad shirts 😂

@@idlemessiah I do tbf lol. Paul's a great presenter.

or we could have the astronaut ride on that same bot, which would work as well, cost less (no jetpack required) and be safer. I agree they look insanely cool but there is no application where a tether-free jetpack would be preferable than a well articulated arm like the canadarm, at least for now.

@@MaximeJean94 Better yet, we can keep the cosmonaut inside, and make the bot do the work. Even better - we can keep the cosmonaut on the ground, and make the bot do the work on remote commands from ЦУП. (This is the MO behind the new Russian station - "occasionally occupied").

Did you hear his wife Carolyn just died last week?

​@@scottmanley No I didn´t. They were such and amazing couple. I just hope she had the opportunity to listen to the homage by Nightwish I mentioned. It brings tears to my eyes every time. Also thanks for these amazing videos you keep producing!

I swear these youtubers all conspire to sync up the subject du jour. Amy's Vintage Space also talked recently about the jet boots experiment on Skylab.

Mark Watney (Matt Damon): Iron Man 😉

@@bobblum5973 Only in the movie, though. In the book, it's shot down for being a stupid idea.

@@Skorpychan Being visually dramatic, I can see why they included it in the movie. I deliberately did not read the book, since I didn't want to judge the movie by its standards, but I should go back and read it now, it's been long enough since I last watched the movie.

@@bobblum5973 The movie is VERY faithful to the book, apart from tweaks for pacing, spectacle, and dumbing down for the average viewer. Definitely worth reading the book, though. And check out Weir's other work too; Project Hail Mary is recent and really good.

@@Skorpychan Thanks! I'd heard about _Hail Mary_ when it came out, yet another entry on my backlogged To Be Read list.

Now compound that to the 107,000km/h the people in ground control were traveling

Velocity is always relative and doesn't really matter. Acceleration is what's impressive.

@@shatterpointgames Linear velocity over distance is still impressive.
