4:39 : "Just keep trying have some whis-Apple juice to keep you motivated and you'll get there in the end with the power of friendship" Matt you are a legend

Maybe Matt could build this in real life for ESA? Those KSP hours gotta pay off sometime!

I do miss your SSTO videos, the interplanetary ones, I feel like it's been a while since you did one of those.

most objects out of render do not model atmosphere along their orbit, so space debris will often float around forever, even though they pass the atmosphere. The solution is, go into the tracking center, select the debris, fly it, and as you render it in, on the next pass through the atmosphere, it will actually model the physics, burn up, deorbit and/or explode.

imagine being the kerbal crew members walking past matts office and hearing through the door "this rocket will be near impossible to control"

I cried when he said the space dolphins weren't real. Heartbroken, matt. HEARTBROKEN.

it really does look like the dream chaser space craft. Matt you make the best videos of ksp. Keep up the good work!😁

If you ever visit Belgium there is a 1:1 concept model of the Hermes displayed in the Euro space center in the south. You can even see it from the highway as you drive by

4:40 That slip of tongue got me cracking.

Would be nice if Europe had its own manned spaceflight. It's unfortunate they didn't built the space plane

please do another video of blunder-birds or a video where you add the "Nauka" module to one of you're space stations!

I’m french and I’m so happy when someone recreate a french space project in KSP so thank you so much Matt

I agree about spaceplanes! I hope the Dream Chaser flies as planed and convinces others that it's a viable concept.

I forgot is not 5:00 Am in the UK so I’m like “why did he post this now?” 😭😭😭

It would've been really awesome for sure. In fact, Hermes was the closest thing to the original Space Shuttle Orbiter.

Petition to donate enough money so he can fly on the virgin galactic ship

Hello there Discord squad ✌😄

When you're so early the video still has 0 dislikes. I hope it stays that way

Still can't get over that Matt never used the angled nose cones on the SRBs. Just GOD it's like such a design feature on the Ariane 5.

French(Cnes): Hermess is my space shuttle Eu(esa): OUR

Guess the closest thing to this becoming reality is gonna be dream chaser

About Dream Chaser / small space planes not being optimal, it's actually the best way to ferry people to LEO and back again. It allows for easier G loads, it is way easier to reuse. It's way simpler than having a propulsive landing and safer too, take a look at SpaceX's Dragon capsule moving away from propulsive landings. Starship obviously has it because it's supposed to land on Mars. It's even lighter than say a Orion capsule or a Crew Dragon.

Actually, the shuttle did a similar dive at the end of it's flight. It could correct distance coarsely by zigzagging, but fine positioning was done with a dive.

I must say I blanked out aswel when you were talking about subscriptions LOL😂👍

"European lack of experience with space technology" as part of the demise of the concept is actually an pretty interesting bit of history. "Technically" what they learned killed some other interesting concepts and also paid forward to programs like the the X-38, HL20/40 and eventually the Dream Chaser vehicles. Hermes turned out to be vastly to 'dense' for the lift it's airfoils and body could provide which was leading to a very high (capsule like instead of lifting body type) heating environment which would have required a very difficult and expensive new TPS development program hence part of the rising costs issue. The aerodynamic issues you had were also a big part of the "problems' with Hermes though this was know before hand and they'd really hoped that non-aerodynamic-surface (aka big fins :) ) could be avoided but that didn't pan out either. Yes Spaceplanes ARE much cooler than capsules but as you note the latter are actually vastly more practical, especially when going beyond LEO. Now not being a Patreon (subscribed and watch but that's about it) I still have a 'challenge' for you to ignore :) Want to try and build a "Lenticular Reentry Vehicle" in KSP? :)

I understand the debris problem. Found that out early on. That's why I have the debris limit amount in the settings at 0. My ingame excuse is that they are laced with a special stable form of solid explodium and once they are no longer needed, the explodium is detonated and vaporizes the stages and debris.

There's something beautiful about the Space Shuttle, my one regret about my trip to America is that I didn't see it on the Intrepid. (And yes, I know Enterprise never went to space but y'know it's the Enterprise, if nothing else, the name makes it a spacecraft)

It’s called Hermies. But all I can think throughout this video is the Martian space ship. Matt you should do a recreation of the Martian Hermies Comand ship

love your content (i will share with all my friends)

I HAVE A CHALLENGE FOR YOU: How far and how much landing could a fully fueled starship go? Arguments: - Superheavy and starship must be stock and fully fueled - The upper stage(Starship) must be refueled in orbit with a tanker starship - Don't need to land the superheavy but MUST land the Starship to complete the challenge - Must land on at least 1 planet/moon except for Kerbin and must be interplanetary Bonus Arguments (nearly impossible): - NO quicksave or quick load - Land on every planets and moons in the Kerbol system (Allow multiple tanker starships) - Rendezvous with multiple tanker starship to refuel every time fly by Kerbin

Hermes!

I love how he said 1 and 1/2 out of 3 instead of 1/2 I love this mans dedication to the unnecessary

Yay! A new Matt Video.

Love the videos Matt! Best Kerbal channel on KZfaq! 😁👍

Bucket List for Matt: Play Kerbal Space Program in Space

Matt:space dolphins arent real me *having an existential crisis: NOOOOOOOOOOOOO WHY WOULD U DO THAT!!!!!??????

LOL @ the "Rich and Jeff" bit! :D But yeah, I'd fly Virgin Galactic too. Anyway, it's good to be reminded of the Hermes, that was a nice looking plane. The video turned out to be a very good one too! I enjoyed that.

The interesting thing regarding Hermes is that it has many different iteration and plans. While the most well known version is the one Matt made here ( 3 pilots + 1x pressurized payload area + expansion with engines and rear docking port), I found there are pre-1986 design that carry 6 Astronauts and has and a small open-able cargo bay (similar to KSP's MK2 cargo bay) and engines right with the fuselage (the adaptor will be just an adaptor with no engines/fuel)

Nose mounted spaceplanes are tough. Helps a lot if you add giant fins (AKA Wings) to the booster stage. The OG Dynosoar program involved big wings on the booster.

I decided to make a replica because i was so interested. I ended up doing 3 of the mk2 fuselages in a circle to get the right size and shape (a whole one made up the bottom, the tip of two made the top, the nose was just clipping lots of parts, the cockpit was the mk2 cockpit.

Did pretty good making it look like the Hermes.

I would definitely watch a stream of Matt 'flying' all the debris back into the atmosphere to save the space dolphins

"Have some whisk-Have some apple juice" LOL

Matt Lowne the SSTO God! Thanks for the idea of a small scale space plane 😍

That cockpit was genius

About the core stage that's in orbit, the game doesn't calculate drag when the ship leaves the physics range, so it doesn't calculate drag, you can deorbit just by changing into the vessel and waiting

It's about family, and that is what so great about it!

8:19 I heard “Leave a comment below and I’ll see if I’m a Lowne in this” 😂 But yes! SpaceX is the future, all hail the soon to be lord of Mars!

Ooo a new vid. I can't watch it right now but have to stop by to like and comment!! 😍

If you switch to the debris in the tracking station(assuming it’s already on a suborbital trajectory) and sly it and just time warp to when it enter the atmosphere it will get destroyed and if u can’t be bothered to do that just hit the terminate button in the tracking station

I did the launch and docking as pilot of Hermes in the real simulator near Cannes at the Space Camp Patrick Baudry, it's quite a memory (in 1990 aged 14). Hermes was quite an elegant proposition, and would not have suffered the same kind of failure the STS did. (others maybe) NOTE : the Dream Chaser still keeps the backward compatibility and options for the Ariane 5 adapter; however a spaceplane under a fairing for me is ... something is just missing.

I have a LOT of stages with a perigee of 30k and an apogee of 75k. My craft always spend extra time in the atmosphere so that only about 70m/s is needed to circularize. I have those fairings for a reason...

For the debris thing, the vessels do not decay if not in physics range, so even if they are suborbital they can stay like that forever. You have to "fly" them and they will decay

There is a way to have a rocket with a space plane on top and having it fly inverted, and without wings, just use lots of reaction wheels and reaction stabilizers. I used them with an HL-20/Titan IV replica

With the ending of development for KSP maybe do a series with some cool mods coming up? might offer a bit more variety, and with the ending of development, more and more players will have the experience with mods. I have a bunch of like internal interactive cockpits and stuff and it feels like playing kerbal flight simulator sometimes lmao

12:06 *gasp* how could you do this!!!

Hey Matt, I know what you mean about the space debris in sub-orbital trajectories that don't disappear from the tracking station. I don't know if it's a bug, or a feature (to prevent loss of a spaceship), but for some reason, if an object has an orbit that just slightly dips into a planet's (or moon's) atmosphere, it won't actually burn up or decay. As you gave said, KSP doesn't simulate orbital decay, so it just has a very simple rule that as long as the Apoapsis of a ship or piece of debris is above 70km, then the Periapsis has to go below a certain height before it automatically destroys it. I'm not certain of exactly what height it is, but I think it's somewhere around 50km-ish. But like I said, that's just a wild guess, I haven't played KSP pretty much since a couple of weeks after the ESA update came out, and even back then, I don't think that I actually knew the height.

The structure of the plane was built very well.

Just saw you in the "Kerbal effect" video from the ksp channel, loving the beard dude!! 😎 Ps; it's nice to hear my favourite ksp youtuber give a shout out to us console players! t's hard at first but you get used to having to dislocate your thumb every 10 seconds to not crash!

Theres this game called space sailors on roblox that is actually making the Ariane space plane, but with the Atlas V rocket,You should check it out!

Hey Matt, I see you still struggling with docking, just wanted to drop down that you can use the target marker on the attitude indicator as a kind of docking port alignment. It is like following the trick of setting each craft to follow their targets but only from one craft, you use the yellow bird to tell you in which direction your moving with respect to the target mark, and you just try to align the bird with the target. I think you know this I just haven't seen you talk about it.

“Jeff [Bezos], I bought some stuff at your shop before …” made my day :D

“Have some whis… apple juice to keep you motivated” 😂😂😂

I would love to see Matt use mods that would be a amazing series

The allure of SSTO space planes is probably because it's the ultimate SciFi space ship trope. Everything from Spaceman Spiff to the Serenity shows us a fully self-contained ship that can take off and land independently. What's not to love? Also, in my opinion "Jeff" and "Richard" should _stay_ in space. Life support optional.

The game doesn't model the atmosphere in objects out of render, and therefore as long as the debris' periapsis is above the surface, and you never switch to it, it will remain in orbit forever. What you can do is go into the tracking station and select it, fly it through the atmosphere, and since the debris is being rendered, physics will be modeled, and the trajectory will change.

Awesome!

In the case when you land on eve Here is a gentle suggestion Send a I accent vehicle To Eve ahead of time And the lender would look more like a space plane This is why it would be a good idea when you land on eve land at the smoothest spot of Eve that you can find

If you get the opportunity, the Virgin Galactic flights are long enough, you could probably trace the flight of Space Ship III live while onboard to do the first KSP video IN SPACE!

There's an alternate timeline where the Hermes was built and became the premier ride to space after STS-135. Heavy demand leads production shortfalls and due to necessity Europe develops a reusable booster for the Hermes and integrates the upper stage into the ship. SpaceX is never founded and Europe once again controls the world.... *starts singing Beethoven's 9th*

Hi

I made a spaceplane right after this like this video and it was ridiculously hard to control.

a mod i use called the knes mod adds the hermes space shuttle and i never realized that it was to be launched on the ariane 5

my morning poops are always comforted by your kerbal endeavors. may god bless your soul Mathew

"Had some wisk....." you can't drunk while flying a rocket "Apple juice!"

Two options for the "false" space debris: -Just terminate it if part of the orbit is inside the atmosphere -Load them up and wait a few orbits until they properly deorbit

Matt your a cool person for liking space planes

Would you do the MUSTARD shuttle concept? That thing was crazy, but I wonder if you could do it.

A great pity this was never made. I agree with you, space planes are cool. One day, (not in my lifetime) we will make real bespoke rockets almost as easily as the program !

the reason why things in the atmosphere sometimes don't de orbit is cause it only calculates the atmosphere physics when flying the ship or being about 250 meters away from the ship so it would de orbit if you go to the tracking station and fly it

YES, FINALLY, HERMÈS

Yay part 2! Thx matt!

I like the virgin galactic one as well Matt spaceplanes need more development

Please please please make a video about the mods you use!!! Those visuals are stunning, and I want a piece of it :D

I tried making a very similar craft and could not fly it AT ALL. It’s great to see I’m not the only one

I gonna use this spacecraft as a crew transportation system for my space station.

We love u matt

Nice video 👍

4:41 - havesome whis-have some Apple Juice to keep yourself motivated, and you'll get their using the power of -Drunk- Friendship - Matt Aug 14 2021

Also make the adjustments later in the flight sometime helps as well

Now you made the space dolphins cry

KSP forum user Well has a very nice European parts mod called KNES that includes two different variations of the Hermes for anyone interested.

The real genius is matt....

Nice vid

It'd be cool to see a drive section attached to the station, then taken on to another planet. Or a moon?

Pretty sure the kill attitude is for parts not inside the physic bubble is 40 km around Kerbin. So if you drop an core stage then Pe is 39 km it will disapear, but if its 41 it will stay. In reality an stage will deorbit after one orbit even up to 80 km.

The blended cockpits make it look rather British, a bit like a Hunter T.7.

I landed on the mun and Minmus a few weeks ago but it was the saddest hours of my day ever

Matt, when sn20 launches you should do a live stream with a ksp starship.

I got the youtube notification for this video while I am 2:35 into the video
