• 2.998 ton manned launc... Duna
• The Odyssey by Bill, B... Eve
• Landing on all of Jool... Jool 5
• 1.3 tons to Minmus and... Minmus
Only Bradley Whistance would find a small, necessary loss in efficiency “psychologically painful”
I feel your pain.
Jerry Rupprecht agreed. I just say “OH IT’LL BE FINE.” Lol. I agree with your opinion about only brad feeling pain haha.
Lol.
He was burning near 45 degrees radial, that is not a small loss...
@@gallopinggoose6891 It's what, like less than 30%? That sounds big, but it's fairly small compared to the 10X+ ISP gained by using the Dawn engine in the first place.
KSP2: **comes out**
Bradley Whistance: 1.8 tons to another star system and back
With no less than 3 gravity assist from Interstellar bodies of less than Mün size.
no killing the sun with solar power
Yeah minimalistic interstellar is gonna be a thing imagine
@@n.m.8802 solar powered radiator to suck all the heat out
@@ahhhshit2327 nah, this is Danny's work
Litho-staging the tank, 10/10
And losing 12 m/s of velocity for extra braking!
Every time i watch a bw video i feel like he's cheating
that was beautiful
11/10 for not crashing another parts
next step: bill gets to orbit and back with only his suit and willpower
He might need to lay off the snacks for that one.
shoopnooop haha
step after that; Going to orbit and back without turning on my monitor.
eva pack has not enough twr to take off on kerbin surfase so he also needs to use mountain launch
@@denisday14 mountains are not high enough for that, but maybe creating a ladder tall enough could get the trick done.
When you're craft is so light that you can feel the impact of the diet of kerbonauts, you know you're go(o)d.
@@MFKR696 yes of course, just like they shaved the paint off the external tank of the Space Shuttle to reduce weight by something like 300 kg on a 2000 t rocket.
Dry mass is indeed the most critical weight saving one can make, especially when it's further on top of the rocket. Just like in Bradley's minimalist missions, adding even a 5 kg solar panel has to be taken into consideration and must be thought out thorougly !
In the notice : "Go to toilet before take off"
you know you are an O
Your*
@@fish-champ ❌️❌️❌️
You're is an abbreviation of "you are"
Your is referring to something in posession of someone, ex. "This Oscar-B fuel tank is *yours*"
This video feels so understated considering he amount of optimisation, planning and understanding of the game necessary for it to be possible. Inspiring to see so many techniques utilised all at once. An incredible achievement.
As for where should be the target for the next minimalist mission, I think I left my trophy on Tylo if you wouldn't mind fetching it...
He already visited tylo in the Jool-5
Tylo seems... impossible lol.
@@LokekoL I'm pretty sure Detonation is actually Damnation
I nearly died when he used the mountain to “seperate”
somehow it's even worse when he does those low passes and he's _not_ trying to blow stuff up.
So did bill
@@nethascotx24 wtf I was thinking of posting this exact same comment
Litho-staging at its greatest !
Litho??
Can you elaborate that?
@@FQP-7024 when you use the force of the ground
@@matsv201 ok thanks 👍
And thermo-staging! (separating stages by burning them off.)
You literally got to Moho with the same weight as 4 Magnetometer booms
Actually last week they made them weigh the same as goo canisters, a more accurate comparison is 2 LVT-30 engines
Ok Brad hear me out: A catapult that launches a kerbal into space where the EVA pack can circularize.
Or if you're feeling daring: a catapult that launches a payload into space where it gets a gravity assist from a moon to enter orbit
Perhaps using a fairing to minimise drag and avoid overheating? The payload in question will have to travel at basically orbital velocity from the moment it is launched, at ground level. I hope that catapult isn't at sea level
He just did that
11:45 "Hopefully you guys are by now concerned [...]"
5:50 the time jump from 1D -> almost 3 years! Still in Kerbin Orbit :'D
You never cease to astound us Bradley.
@Jennifer Wang ayy :D
Agreed.
Next mission: sepatron to the surface of Jool and back
Define seperatron.
You see this looks like a rocket, but it's actually a seperatron for the rocket that will carry the ksc into orbit.
Swdennis did decouples only to orbit, and the surface of the mun, but he couldn’t come back.
Why do I feel an r/wooosh coming?
@@bluemoonjune5178 No! Not funny.
It require propellers. stratenblits did this without separations but with refuelings
The madlad. My family car weighs sour as much as the rocket. Holy shit
Then get those car keys, we're going to Moho.
A good and easy one to pull off
@@connordarvall8482 Mom, are we there yet? Only 3 more gravity assists, sweetie.
Get in loser, we're going to Moho
Love how we shed 12 m/s through genuine lithobraking.
3:11 - Their low heat tolerance actually makes a lot of sense if you think about it - the basic fins are stated in-game to be made from aluminium, and aluminium and its alloys weaken and melt at much lower temperatures than other commonly-used materials.
Excellent work
Everyone asks where is Bill Kerman, but nobody asks how is Bill Kerman?
It must be “psychologically painful” to go into space for a literal decade in nothing but a chair with solar panels.
This may be the most important, aware comment ever.
@@BradleyWhistance lmao im just seeing this now and this is amazing lol
@@BradleyWhistance yes
don’t worry, bill has a phone and a cable.
You can tap P to deploy a kerbal's chute
thank you for this great knowledge, O wise one
You can?
Aye, a novel installment of roasting kerbals:D
Litho-staging has to be both the smartest and stupidest thing I've seen all year. 11/10 made me laugh like a hyena
8:25 - Is "burns" really the right terminology for an engine that isn't combustion-powered?
Not criticising, just wondering.
English isn't really embarrassed about using anachronistic terms to describe modern things
Note the B-36: 6 turning, 6 burning.
@@bradyelich2745 *4 burning, it only had 4 turbojets
@@dsdy1205 Thank you. I am watching the video now. Refresher course.
I think 'thrusting' would be more correct, but nobody wants to say that
me: knows a decent amount of the game but still can't make SSTOs possible
this guy: goes to moho with two tons
I still am unable to dock in orbit. I can do it on the runway ... I found a map of Delta V one needs to get to the various destinations. The map cut out thirty failed launches on each new game.
@@bradyelich2745 We are duality of men then, I figured out how to dock around two weeks ago.
It's really just waiting until you're close enough, burn retrograde from your target until its zero, point towards the target and then thrust forward.
I'm still janky on the RCS part lol
@@inactive9948 I tried the training missions two or three times and still failed. I have a failure in the mouse control department. I do not think it is the mouse's fault.
@@bradyelich2745 Ahh you'll get there, it's really janky at times but I have faith
@@inactive9948 Thank you for your support!
9:20 - Is Moho the highest-surface-gravity body that the Dawn can lift its own weight on?
It is! However, Vall has even lower margins in practice, due to the high efficiency of photovoltaic electrical generation on Moho and the need for batteries on Vall.
I just realized that your videos are way brighter than other KSP videos which means that I can watch without cranking the screen brightness up. Nice!
Thanks to the developers of the mod "Ambient Light Adjustment" for that
When you make a loophole just to use it to break a record
F1 (any car racing series) Baby
You disgust me. Sending that poor Kerbal all the way to Moho with no snacks, no sunscreen, and no A/C.
4 Dislikes? Let me guess, Jeb, Valentina, Bill, and Bob.
the frick
Brad, you never fail to impress me. I haven’t even BEEN to Moho.
Must have taken a lot of attempts to properly "eject" the xenon tank at moho, impressive stuff!
for once i want to see a mission without an "and back", just leave them there
Can we get an “one engine to everywhere” ?
(without leaving any debris in space or on the surface of planets, as additional challenge if possible)
Depends on how you categorize "one engine". You could always make dockable containers and fly them up to orbit individually with one engine and have infinite fuel with sufficient time.
@@gajbooks I assume the challenge would be minimalist as well
Ze Great Pumpkinani or everthing has to be launched in one single time, no coming back to kerbin to take additional fuel
Matt lowne did one with 4 engines and maybe a few others to get to orbit
Is anyone hyped for the minimalist grand tour (hopefully at the end) as i am?
I am only hyped for The Grand Tour to re-appear on Amazon ... I fear the Boys are done.
I was going to watch old venturian tale, but then suddenly this showed up.
*You've caught my interest.*
Hello Elyas.
Still don't get how he thinks up those kinds of transfers/gravity assists. Can I get some more detailed explanations?
This specific chain of gravity assists occurs regularly (at least IRL) because the planets are in whole integer resonances with each other. Finding them however takes some time.
See Earth-Venus-Mars cyclers for more details. (papers from the 80s that found and explored theses resonances IRL. KSP probably has them as well. ) the magnitude and direction of the gravity assists are controlled by your flyby speed, the closest distance and your angle. that's how you can both get faster or break with the same gravity assisting body on different flybys. Using earth for gravity assist can also help with plane change and when antenna strength is of concern. You could get arbitrarily strong gravity assists for your spacecraft, IF you could get arbitrarily close to the body. Aerobraking and lithobrakting are factors to 'consider' however ^^
Please can you make a video on how you plan gravity assists, I understand the theory of gravity assists but how to align the mun eve and kerbin like that makes no sense to me. Are you just doing dozens of solar orbits we don't see to get the window right or is there some crazy planning methods?
Wow, the KSP community keeps blowing my mind with what can seemingly be done. I wouldn't have believed this was possible yesterday
Ejects wings and fuel tanks by overheating them and crashing them into a mountain to save weight
Modern problems require modern solutions
no way you pushed your craft up the mountain for like 1 dv
Can you do something insane on Real Solar System aswell? I Recommend trying principia, you can exploit astrodynamics even more like that!
As you were describing the gravity assists at the Mun, Eve, Kerbin, and Eve again...
I realized that's actually pretty close to the plan for the ESA's BepiColumbo mission to Mercury, with its assists from Earth and Venus.
The madman himself has returned and once again showed everyone why he’s the best.
Bradly-accidentally burns the ion engine for .00001 seconds longer than intended
Also Bradley- we might need to use the EVA pack for the capture burn!
"Who the hell need separators for a craft?"
Now knocking off an tank by bumping into an mountain at 1 Km/s. Honestly how many reloads :)
Granted I had some close calls but that was hundreds of meters not cm.
But I'm one who go barnstorming in an SR-71 on afterburners.
Correct response is: can not respond, DARPA NDA :)
I was just thinking, could you gravity assist of Moho just like how Messenger IRL gravity assisted off Moho to decrease the capture burn?
I'd love to see a video on a vessel that through its own ISRU is able to return worth double the funds it cost to launch
That would be a unique challenge!
Use Kethane and I believe KSP Interstellar; the kethane can produce Xenon, which is much more valuable than the mining craft.
First #LandAmerica, then a new minimalist Brad video? Can this Sunday get any better?
I don't know if they fixed this but apparently, you can use a fuel drainer on an air intake and it will produce thrust. Since Intake Air is infinite as long as you're in an atmosphere, this basically produces nearly infinite thrust production. This works because Intake Air gets counted as a Fuel Resource by the game.
That was fixed in 1.9.1.
all of the separations would have been easy if bill packed a screwdriver.
but this was a huge achievement, don’t get me wrong. good job
But a scredriver would weight 200 grams
River Shen true, but he could lose some snacks haha
I love how you implement your explanations using real physics instead of "simplifying" it.
Wow..... Do you have a video or know of a good video that shows how to setup and execute multiple gravity assists like that?
NICE JOB! Turbo pumped cannot beat you now XD
Also all hail the return of the space chair! Bill will surely be excited 😁.
I was watching this to wait for ksp to load but the loading screen has Nyan cat???
Do a speed run to Jool and back as fast as possible efficiency is not a priority speed is
What a great mission! :D
i wish you'd comeback when KSP2 launches
Hey bradley, you should do minimalist missions on the "beyond home mod"
I'm not even surprised at this point by your shenanigans.
Next video is probably landing on the mun with 10kg propellant
Imagine sitting in a fucking chair in the void for actual years
I'd be super interested if you made a video about the aerodynamics in KSP, since you have clearly become the kerbal equivalent of an airbender over the years
Actual lithobreaking, finally used in an actually useful way!
Truly the most kerbal of maneuvers.
I just figured out how to perform a tylo gravity assist. So I think I have a new appreciation for the amount skill, time, and effort required to do this.
I just went to both mun and minmus for under 5 tons, thanks for teaching me
DM2 just landed!
10:30
Bradley: We're gonna have a lot less Delta VeE
0:10 beE
I had to use that same trick of pointing up just to get a stable orbit just today, when I had to haul a 50 ton payload to minmus with definitely-not-the-highest-tier rocket equipment..
I've got pictures of my accomplishment (and the payload) on my steam account (Squishybrick).
It looks like a friggen castle, and it's the most awesome thing I've ever done in KSP, so far. But I'm constantly improving and learning, and I love that videos like these, that I used to watch and just glaze over the words, now I'm actually hearing the strats used and not only understanding them, but relating to them.
That's just amazing.
Burning off the wings was very clever! Great job 😃
1.7 tons to gilly and back or 1.9 tons to ike and back
Truly amazing Brad, so fun to watch =]
Intersteller mod? Minimalist craft to another star system?
This is phenomenal, how are you able to plan this to the level of detail required? Such as dodging that jagged ridge on moho? It's amazing
i like how when you send it down the mountain bills expression goes from reassured to panicking, and it just keeps cycling
ksp has really reached the endgame
Excellent work, sir! Your dedication to the game and to us is inspiring - as for a new destination, I don't think you've made a minimalist visit to the Kraken on Bop in some time...
I kind of want to see the smallest possible craft that can make it to Eeloo and back
I believe HoDeok has that one covered (at least for now) ruclips.net/video/PBTubvuo2ow/видео.html
Can you make a plane that uses the lease amount of weight possible per passenger to get to leo? The bigger the better. Also if you fancy it, maybe ask audible for a sponsorship and recommend seveneves because that’s badass and basically the plot of the book 😳 (just don’t mention that the book is 32 hours long) although I assume that prob wouldn’t cover half the duration of the designing and testing phase for one of your ambitious missions 😬
Idea of mission:
Fly-by all bodies in the kerbol system with less than 1000 m/s of delta-V
The FLAG!!!!!!!!!!!!!!!!!
Use moho gravity assists to lower cost of dv
I hope you don't say "battery bank" anymore as it makes no sense.
They're called power banks because you deposit and withdraw power, not batteries.
Doesn't even land on the helipad smh 0/10
Maybe a challenge with the Outer Planets mod could be interesting
Wait, is that the old hot rockets mod?! Cool!
I know I'm 2 yrs late but pls tell me how you know how high to gravity assist and when to launch to get the perfect trajectory
Can you list all the equations you used to calculate this mission? Or the tools you used to help calculate the mission?
Make a ship to go to Moho, and Eeloo and back!
8:52 How in the fuck do you even approach considering something like this? HOW? BRADLEY?! HOW DID YOU DO THIS
my god... solar panels, reaction wheels, MULTIPLE FUEL TANKS? bill is practically taking a luxury cruise on this one
I know this is years old now, but just curious at 8:00 if there would be an efficiency gain by capturing at Moho in a retrograde orbit (e.g. clockwise when viewed from the north) so you can capture on the sunward side of Moho and make full use of the admittedly weak oberth effect, then once captured into a maximally elliptical orbit, you turn around at apogee which would only require a few m/s.
Then you can lower your orbit using tiny periapsis kicks relying only on battery (for greater efficiency).
I'm really not sure if the improved capture efficiency with the Oberth effect would counteract the additional DV requirements to turn the orbit around, but it's an interesting thought regardless.
I think the transport craft is fair. After all, you would need to use a crawler to get it out of the VAB, so either way there's some kind of vehicle involved in moving it to the launch location.
It'd hardly be fair to include the crawler in the mass calculation- your crawler is just more of a... flier!
Edit: I assume those 38 kilograms left over are the large supply of pizza Bill plans to ration out over the course of the trip, right?
Pizza would be an optimal choice, naturally, since it tastes surprisingly good cold.
your [minimal mass rocket]siries have become much better ;D,but I saw somebody flying to moho ysing only 1.675tons. that guy uesd the spark to get to space like your 2 ton to minmus. he then used ion and jetpack to fly.
Do you think SpaceX and NASA watch these and are like 'too easy git gud' or like the rest of us 'well I mad it to the mun (moon) a few years back... wait, what, how the specific impulse did he do the Space. Some one call homeland security! RUclips channel goes silent.
Cosine losses are actually surprisingly modest until you are at very severe angle of attack. For a 30 degree angle of attack, you still get 87% efficiency. For a 10 degree angle, that's 97%.
Next destination: Dres. We have to see where they faked the mun landing.
Look, I get this is a joke, but imagine doing something way harder to fake something easier
Do one to the outer planets or the asteroid belt pls
what happened to your clouds
Gib how to build tutorial pls! I beg u
Him: this is very simple. Just do these 4 gravity assists!
Me: umm, excuse me? I can't get a rocket into orbit in one piece. I don't think I will be able to do 4 gravity assists
Decouplers, what are those?
How about lowest mass circumnavigation of Kerbin? Take off from the airfield and land back on the airfield, circumnavigate the planet within the atmosphere with the lowest possible mass.
