[@petlahk4119]

Actually, if you're weird like me and part of the considerations you put into building in KSP is minimizing launch cost, and maximizing Delta-V, no. Probably the reason we don't get rockets like these in the commercial sector is because they aren't efficient in either of those two ways. The military pays for the losses in efficiency because what they are after is in-fact that very fast acceleration and speed, so the thing is harder to shoot down.

[@ExaltedwithFail]

@@petlahk4119 also its incredibly difficult to make a reliable asparagus staging rocket in real life and most of the stuff we do in KSP would be very hard to recreate without a massive fail rate. When i make the most efficient delta V rockets its usually got 7 large bottom rockets with asparagus staging and then similar setups for second/third stages depending on how crazy of a mission im doing. Also alot of rockets have issues of reigniting once turned off in space which makes some of the stuff we do impossible

The fastest the warheads arrives on target, the less time there is for interception and to launch a retaliation strike. It's the whole point of space-based warhead launch platform as Soviet envisioned them, basically, no launch, no delay, just nuclear doom surprisingly knocking at your door. When militarization of space got banned, they devised the dead man's hand automated second strike, a system that would launch an all out nuclear rain on the world in case of a first nuclear strike, to ensure the world to be erased if Moscow falls. Sovies puts the MAD doctrine to the extreme, and the fun fact is that this device is probably still ticking somewhere, forgotten in an abandoned bunker, waiting to obliterate mankind on a false assumption, Skynet style.

Another way in which Dr Strangelove was scarily accurate.

It turned out to be so accurate that the USAF investigated to see if they'd actually been spying.)

[@johndemeritt3460]

ICBMs are meant to run like a raped ape -- once the launch order is given, you don't want to have them hanging around trying to get into the sky. That's why we abandoned liquid fueled ICBMs: if they're not pre-loaded with propellants -- like the Titan IIs were -- you've got to load the fuel and oxidizer before your missile can fly. And if you have a missile like the Titan II loaded and ready to go in an underground silo, you have an accident waiting to happen. Just ask the residents of Damascus, AR.

11:55 That was part of the design requirements for the booster: sit in a silo for years, but still able to fire within a minute or two of being activated. Probably they had some sort of stabilizers mixed in with the fuel grain, so that it wouldn't degrade much over time.

[@RCAvhstape]

The thing about Atlas and Titan is that they were such good launch vehicles, and so inadequate as alert-worthy weapons, that they actually stayed in production as launchers long after they were retired as weapons. These solid fuel jobs, on the other hand, are really optimized as weapons, designed to sit in storage for years, like cartridges in a rifle magazine, and then work simply and reliably if fired in anger. They will get warheads to the other side of the planet very quickly, but they aren't as efficient as liquid fueled launchers, can't lift as much mass for a rocket of their size, and their high accelerations, desired in a weapon, can be rough on more delicate payloads. But it's good that they've found a niche launch market.

Sitting unused for decades, and then being ready to launch at a moment's notice with high reliability, _was_ kind of the main design consideration when they drew these things up.

I became TRW's Stage IV Development Engineer, but my goal in life was developing commercial space launch vehicles. It turned out that the manager of the engineering division of TRW/BMD was a former NASA person who shared my passion for commercial space, Dr. John Thole. He had brought one of his former NASA colleagues, Bill Schindler, into BMD. Bill was known as the father of the Delta launch vehicle, having managed the program from its first launch through the year NASA told him to shut it down so that it wouldn't compete with Shuttle. The three of us schemed to get TRW into the commercial space launch business, using ICBM technology. A fortuitous reorganization put us TRW/BMD into the Space & Technology Group, under the management of VP Dan Goldin. He ultimately became our champion, and we developed on paper a family of launch vehicles based on the Castor 120 and another Thiokol upper stage, vehicles which would have significantly reduced the cost of space launch. As a bonus, one of the AF/BMO Colonels that we knew, Ted Kehl, retired from the Air Force and took a job as heading up the launch vehicle procurement organization for Motorola's upcoming IRIDIUM satellite phone constellation. We were the only company who bid both constellation launch and maintenance for IRIDIUM, and were told after the fact that had we only submitted our proposal, we would have won the whole thing. I don't know if that's true, but we never got the chance. Dan Goldin was tapped to become the Administrator of NASA, and the company shut down the TRW Launch Services Organization one week later. I won't go into the subsequent theft of intellectual property too deeply, but someone else did use our technology to launch two spacecraft. One of them, Clementine, went to the Moon. Bill Schindler passed away before TRW shut us down, and John Thole went to Orbital Sciences. I started my own attempted launch company, Kelly Space & Technology. Thiokol was bought by ATK, and ATK was acquired by Orbital Sciences. TRW was bought out by Northrop-Grumman, and the whole shootin' match of Orbital ATK Thiokol TRW is now Northrop Grumman. The use of ICBM and ICBM-derived stages thus has a long history (I have left a lot out), longer than this video captured. But it was a really good video. Scott Manley does an excellent job.

hey scott, ive got an interesting idea that id like some feedback on. So ive been rewatching some older videos of some other youtubers and saw them using peltier units as coolers. apply voltage and it makes a hot side and a cold side. these can be used in reverse so cool one side and heat another to create voltage. now my idea is for low power satalites. using the special paint that is absolute black and absorbs 99% of all light energy, paint one side of the peltier so it gets hot. the other side will stay cool and generate power. do you think this would be a viable alternative to solar panels in space or do you think it wouldnt work as effectively?

[@markuskoivisto]

It would essentially be a really inefficient solar panel.

[@joshjohnson9423]

Taurus actually used the Peacekeeper SR-118 first stage on it's first three flights before switching over the Castor 120s. Minotaur I and Minotaur II are the only vehicles that use the Minuteman II hardware. I got to work on all the Minotaur vehicles (4 launches in total) and that was one of the best jobs I ever had.

Swords into plowshares, of a modern sort?

[@liamtiam8828]

I saw the NROL 129 launch and it was my first! I LOVED IT!!!!!

Your research is fantastic Scott!

At least he made it safely across the road...

Star-Trek Fun Fact: Zefram Cochrane, born in 2030, used a Titan II to build the worlds first warp-capable space ship. It launched in 2063 and at this time Zefram already looked like he was 70 years old, even though he was just 33. All the engineering problems, trying to invent the impossible, gave him grey hairs. ;)

[@robertsutton8894]

Especiaaly with over 100 year old Titan 11's Maybe ask him how he did it in 20 years.

Do you watch without audio? If not, try to listen a bit closer :) Scott talks about it.

[@fchanMSI]

You should see the silhouette of the frog in the exhaust plume.

My aunt designed the final method for making the nose cone of the Minuteman II ICBM. The nose cone was never able to be balanced correctly. She was a mid-level engineer working on that missile (as well as the first couple space shuttles before retiring). After some literal paper mache and wood glue experiments on her dining room table over the course of a weekend, she figured out how to design the mold so the injected material would balance itself out naturally using gravity, then trim off the excess and sanding down any irregular spots. It's fun to think that the missiles being launched were some that she had worked on... she worked on many designs, not just the Minuteman II and the space shuttles. She has since passed away, but one of my uncles got a lot of her homemade instruments - I have many of her hand tools and measuring devices... did that pair of calipers she willed to me touch that missile we just watched launch in this video?

[@jimmyseaver3647]

Nice to see those swords used as plowshares.

[@jimlarsen6782]

You certainly do research into areas that are relavent and interesting. Thanks Scott.

[@Anno-ls5uu]

I love how KSP this is. „Yeah, let‘s take this existing SRB and just stick this other existing one on top, that will surely get us to space“ :D

Cool stuff. Whatever gets us closer to low-cost, daily launches is highly welcomed.

Every payload should be declared and known to all of the world. Should be a global right to know what's inside.

[@hooveyjones]

It says something about humanity when the worlds best telescopes are pointed back at earth rather than the cosmos :/

[@fishsticks4981]

its not only amazing that these rockets have been sitting and are ready to go but also scary

[@AirJimInCT]

Thanks for the awesome video Scott. Cheers!

[@nothingtoseehere1097]

Great video, Scott! Thanks!

[@EwingTaiwan]

2:22 I didn't know that 中華衛星二號(FORMOSAT-2) was launched on one of those!! Thank you Scott!

[@johnladuke6475]

Hmmm, obsolete or undesired as weapons, legally complex to convert to commercial industrial use... I'm feeling like this is a perfect opportunity for surplus sales direct to private citizens. Most of us would do something horrible and foolish, but imagine what learned people like Scott might accomplish with an orbital launch vehicle.

[@tomwatts703]

I got the pop-up notification saying 'Decades-old Nuclear Missiles Finally Launched' and genuinely for a microsecond thought someone had launched a pre-emptive strike

[@robertsutton8894]

That was the idea for WW4

[@thelovertunisia]

Scott, with the advent of cubesats and the ongoing miniaturisation of payloads, solid fuel rockets are living a comeback and they are a potential cheep spacd option for smaller countries since they dont have the sophisticated machining and plumbing required for liquid fueled rockets.

[@blurglide]

Liquid thrust vector control actually pushes the flame to the opposite side. It isn't an oxidizer and doesn't increase thrust.

[@StealthTheUnknown]

Pretty cool to see old hardware used for purposes other than strategic deterrence or glassing the surface of the planet.

[@benperry490]

I may or may not have worked at orbital in the early 2000's on a target rocket for testing pac 3 shoot down capability using old Pershing 2 missiles (trying to simulate scuds), I remember laying in the nose cone area drilling and attaching brackets for various devices thinking there used to be a nuclear weapon in here
