Years ago I read a humorous sci-fi book that was basically a dystopian military bureaucracy on a space station. Imagine Catch-22 meets Office Space in space. It ended in the most epic way possible: with the hero using a one-man escape bubble to jump back down to earth, where he landed in Texas and walked into the nearest bar. Edit: I found it: Orbital Decay, by Allen Steele. At the time it was just a cool one-off, but I just found it it was the first of a series and he went on to become a best-selling author so I guess I've got some more reading to do.

The chance of something happening both to the station and to the escape system at once is very low (and most likely would result in no astronauts left to save).

Nothing succeeds like success. You can return a lone stranded Kerbal from well within the orbit of Moho (very close to the Kerbol, the sun) to a fairly safe Kerbin orbit, where she can be rescued by economically feasible means, with something like that! The down-side is that it takes virtually the largest delta-V possible in the game to get the ion-drive-equipped lawn-chair rescue package payload to an orbital rendezvous that close to the sun. Or, about 30,000 m/s. Once she's aboard, the rest is fairly straight-forward orbit-wrangling. To be clear, it's an ion-thruster propelled lawn chair in my version. The mission is called "Big Intrasolar Technically Challenging Headache Prototype Long-range Electrically Accelerated Search/rescue Equipment". So-far it is by-far the hardest rescue-mission in this version of KSP. It's colloquially referred to by the technicians who operate the mission as "B*TCHPLEASE". The mission-patch is completely awesome, and the rescued Kerbal, Clauby, will get to wear it with pride. She will also out-rank even Valentina and Jeb when she gets home.

Hi Scott. Thanks for this video about the X-38. I worked on this vehicle at Houston, focusing on the High-Voltage and Low-Voltage DC bus distribution boxes. I wish I had better videos to send you of testing, but alas, I don't.

Way back when I worked for McDonnell Douglas (MDAC) at KSC I was part of a team that was supposed to evaluate systems for what was internally referred to as the GTFO (Get The F... Out) for Space Station. It never materialized. The problem with all these ideas is the additional cost to develop, build and maintain. The thinking always came back to using the transfer ship as the rescue ship because you already have it. Shuttle was a problem but even back in 1988 there was talk about partnering with the Russians for a long duration escape ship.

I've seen the X-38 on display at the Evergreen Air and Space Museum! I Initially thought it was a pretty detailed mock-up, but looking closer at it, I realized that it was an actual vehicle! So cool!

Scott, “Home safely in any emergency” is quite a bold statement! Yes the spacecraft used today for ‘Orbital’ missions do indeed have redundant systems. But should anything happen to to the spacecraft itself, such as broken hatch hinge, puncture to the skin of the craft or damage to a window seal or cracked glass panel, the integrity of the airtight worthiness would be in jeopardy! I believe the X-38 was an outstanding idea and something similar should still be pursued. Even if the ISS gets retired, we are still going to be putting people in space and they should have some kind of lifeboat pre-staged in orbit. Just my two cents…

"No shortage of ideas" is a phrase I'm going to use more frequently in meetings to call out bullshit.

The X-38 was never the ACRV. They were two different vehicles and project offices. The ACRV preceded X-38, originally being called the Crew Emergency Return Vehicle. The name was changed because NASA didn't like the word Emergency in the name and what it implied. The ACRV had proposals from Rockwell and Lockheed for entry vehicles, Rockwell's being a scaled up Apollo of course. I worked as an engineer in both projects. I was responsible for the three paintings of the ACRV that you used in the video when talking about SCRAM. The vehicles in the paintings are clearly marked ACRV. The X-38 was always referred to as the X-38, never as the ACRV. At one point during ACRV, our office had discussions with the Russians about the US obtaining Soyuz capsules to fill the role of a return vehicle until we got the ACRV operational.

The idea of using a paraglider wing to land is quite interesting. Normally we don't like wings on spacecraft, let alone rockets, because they introduce additional drag and weight which is a big no-no at the moment of launch and cruise. However, paraglider wings are very light (because they're made of fabric) and are stowed until use, so they might be a workable solution to land a rocket. Would be pretty cool to see a giant reusable suborbital rocket land on a giant parawing.

In all fairness to the Sci-Fi genre and their escape pods, humanity is nowhere near the level of orbital construction (we have zero orbital construction, only orbital assembly) that would necessitate the need for escape pods. The fact that we send pods up means by default, we have pods available to bring people down, so there's no need to engineer anything else as it's purely an expense that essentially gains you nothing in return. When we get to the point where we're building oil tanker/cargo ship sized ships in space and we're not launching crew modules every time there's a shift change, the whole 'life boat' system will have already been revisited and figured out, and put into place so people can stay in orbit, work, and come back when the new crew arrives in what surely will be something much bigger than a soyuz or dragon. Perhaps Starship delivering 100 people at a time for a one month rotation. I highly doubt with an orbital platform on fire and breaking apart in a worst case scenario, we'd not have escape pods not scattered about so that whatever ship that is the usual crew ferry isn't sitting there waiting for every last person to board while everything burns and deorbits around it.

"austere: (of living conditions or a way of life) having no comforts or luxuries; harsh or ascetic" Taught me a new word today. Thanks Scott Manley!

In KSP I made up and tested a tiny escape pod concept: Docking port, probe core, battery, inflatable airlock, and 4x drogue chutes. Your ship still needs to be healthy enough to start the deorbit, but that tiny list of parts will safely splashdown a Kerbal from at least up to 2km/s reentry. The docking port is the heat shield, and the docking port/probe core/battery stack make it the fat and heavy end of the pod so it reenters that way nicely. I very loosely based it around the inflatable "rescue-ball" concept that's featured in the "Space Shuttle Operator's Manual".

I'm always interested in more of the "unsung" history behind our space exploration, so this is just right up my alley! Thanks, Scott (and those involved in making the episodes)!

Reenter the atmosphere with a heat shield on your back is something for when base jumping has become tedious :-)

I like how with MOOSE they go "deorbit yourself first, THEN build your reentry vehicle." So if absolutely anything goes wrong in inflating a giant plastic bag with foam while you're inside, you have no abort option to get back to orbit.

Awesome breakdown and explaining! Thank you for your work put into this!!

There is always the option of the Dark Star "wreckage riding" surfboard :)

For my stations in Kerbal I usually added commandpods with a bunch of Seperatrons, a heat shield and set of parachute as a lifeboat

I think Skylab 3 suffered problems with 2 thrusters. Which is worse because then you have to consider the possibility that there is a flaw in the whole batch. The Cm could easily come back with one or even 2 failing thrusters, but what if on the return journey one or more fail? So while the crew was in Skylab in orbit, Houston and contractors a. tried to find out if there is a fundamental problem with the thrusters and b. simultaneously preparing the rescue CM. The backup crew was involved in both efforts. he irony is that by finding that the crew could come back, the backup crew cancelled their chance for their own space flight (in the long gap til the shuttle). And of course Al Bean and co. brought the thing back in probably one of the more interesting flights with a Apollo CSM. Also even when Freedom was still freedom, the idea of buying/renting a Soyuz was already floating around. Not quite sure, where i read that. Jerry Bosticks book probably or Stafford..

Brilliant. Thoughtful and informative (with a good dash of opinion) as usual.

Haha! I remember playing that version of Star Wars on the BBC Micro. Cheers Scott! 👍😎

One of the most interesting talks l've yet heard. Thanks Scott. 🤩

Thanks, Scott, for explaining this matter. Great job

What do you think of the idea of using Dream Chaser as a dedicated lifeboat?

Really love your work Scott, thank you!

Imagine if the inspections of the Shuttle thermal protection system was done more seriously from the start and that the Shuttle had an escape capsule like this, then the Columbia disaster would've been prevented. Just my 2 cents.

It would make Shuttle heavier and even more useless it already was, Columbia disaster would never happen because entire program would bankrupt before then.

This was something that was thought of long before. My uncle designed and built an inspection drone called AERCAM in the late 80’s/early 90’s but it never flew save for one demonstration mission in ‘97, because it was simply too heavy due to scope creep by the big heads at NASA Johnson. Interestingly, one of its’ descendants flew aboard Cygnus last year as part of one of its post ISS departure missions. Hopefully a positive sign of things to come for future missions.

The only aerospace escape capsule that I was aware of (until just now and the new to me example of the B-58) that was actually built and used was on the F-111. They were reported to work quite well in actual use. Of course, the problems that an in-atmosphere escape capsule need to solve are far simpler than of an orbital escape capsule; and that is sugar coating it!

Actually they didn't work well, mass of the capsule made landings really hard to the point crew could not leave it afterwards, in one time capsule was used both pilots ended with broken spines!

@@randomnickify Interesting. What you say makes sense. My recollection was based on media reports far in the past (before the internet!) on Australian operations of the F-111. You are no doubt better informed than I am. Spine damage was a potential problem for all ejection systems that I am aware of. Having actually witnessed a zero-zero ejection while I served, I'm not surprised. It is brutal.

@@MarkHarrisonBNE IIRC the Australian F111 ejections were all over water - none were zero-zero. The capsule proved to be a fine lifeboat - quite seaworthy. I wonder if the other escape pod ideas all floated?

Nice clip, really enjoyed it. 👍🏻

ooo the bit about how long the shuttle can stay or orbit is a snarky little inclusion and im loving it

Thanks for the video Mr. Manley, it is neat and clear as usual. Just wanted to express my disagreement with the "emergency escape system" being the same ship that transports the astronauts to and from Space. Giving redundancy to every system onboard do not provide a redundant separate mean of escape. Gemini had rocket-propelled ejection seats, Apollo had its solid rocket motor on top. Then, the Space Shuttle had yes maximum redundancies but no escape system, and blew up twice. Soyuz and Dragon both have escape systems; because the First Corollary to the Murphy Law clearly says that: "Your astronauts are going to need an escape system the moment you remove it from your Spaceship". Thank you - once more - for all the continued and very well documented updates you keep providing. Me lazy, I just thumb up and watch them...

aslo the spacex dragon capsule itself can also be a escape pod for the iss! with a massive crew capacity from as low of 6 to a maximum of 12 astronauts and more than enough fuel after being docked from being launched from earth to help get the astronauts back down in a emergency! it even has its own dedicated solar and battery power supply that can even help keep some of the iss systems powered in a emergency and it's also far cheaper then the most what NASA could come up with! heck starship could even cram a dragon capsule in some variants like the moon and cargo variants for an emergency if spacex wanted to! or they can even have crew be transferred from earth to the starship for interplanetary long range missions via dragon capsule to save a lot more fuel for starship's missions for going to the moon and mars and beyond!

Anybody else notice the Apollo CSM in the CERV proposal? Either they were gonna convince the manufacturer to build some new ones, or they were gonna upcycle the ones they had left over. A ship originally built to go to the moon, reused as a lifeboat.

That ending Scott. Lol Great video!

One of the things i liked more in Kerbal was to retrieve Kerbals from moons with individual minimalistic engines. Very fun thing to do.

".... and a whole-lot of bad assery.." Scott - that comment was just great!

Love Scottish humor: stars wars ref, "badassery ", potatovision. Lol

This channel is pretty much my real world escape tool.

An escape pod is one of those things we won't perfect, probably, until a few people have died. I imagine any given escape system will be heavily dependent on where the nearest human presence is that has an energy surplus great enough to rescue them. If I was going to be in deep space most of the time, I'd probably spring for a really good black box instead of an escape pod. With a station in low orbit, ideally, every module would be able to survive re-entry and control their descent to some degree. In the middle, there's an ocean of 'hope we got enough fuel'.

Great and Yet again Interesting Vlog thank you Scott

"Ideally, close to a place where they can get a drink!" 🤣😂🤣

Fantastic stuff. Makes me want to make escape modules in kerbal

I remember when the X 38 was a project I remember watching the drops on the b-52 on a discovery channel documentary

As always a plesaure! Thanks Mr Scott

When he said "thankfully no bear" - I thought he was referring to the "Spaceballs" escape pod scene :-)

This is so sad. Having those escape gliders on the ISS would be so fucking cool.

I think a good explanation for why the gunners in Star Wars didn't shoot the escape pod is that instead they digitally tagged it so that they get a cut of the profits if the pod is salvaged. That's the best idea I can come up with.

that moose thing is absolutely next level. gotta love that era.

In Jan 1999, while working in Houston, I took a tour of the Johnson Space Center and saw one of those vehicles in a semi-clean room and the tour guide said that one was actually going to be flown to the ISS. Now I know why I never heard of it actually flying.

You didn’t mention all the Dream Chaser craft on the outer ring of the Voyager Station concept.. since it would be impossible to dock to the outside of a spinning station then the only purpose they could serve is as escape pods..
