@Matt Horkan It'd take several years perhaps decades for the right orbits, and your cosmonaut would be in a space suit in a chair, what is this cabin you speak of?
You know, originally I thought the crazy gravity assists you do didn't happen in real life, but after reading more and especially with the recent Trident spacecraft proposal, I realised these gravity assist routes are fairly common. For reference, Trident is planning on launching from Earth, then doing an Earth, Venus, Earth, Earth, Jupiter, Io gravity assist route to get to Neptune.
Administration Building: It's impossible to do this. Brad: *drifts up to the doors of the Administration Building after doing the thing(tm) AB: Oh. You, sir, are a legend :D
_Bill walks into KSP_ Everyone: Bill? We thought you were dead! Where have you been? Bill: Remember when you guys said an SSTO to Tylo was impossible? Everyone: I mean, vaguely Bill: well I just took an SSTO to Tylo AND Laythe Everyone: Is that seriously the only reason you left? You’ve been gone for forever! Bill: 75 LONG YEARS
The limitation in this case would be specific impulse. Even the nuclear motor isn't efficient enough to let you add so much fuel to it. So, I assume that without staging, it's impossible without mods or an exploit that hasn't been discovered yet.
Landing on a planet or moon without an atmosphere requires lots of delta v, there is no way around that (you can get rid of some horizontal velocity with brakes, as demonstrated by Bradley countless times, but that’s about it). For Vall and Tylo you need rocket engines, ion engines are too weak and air breathing engines don’t work due to lack of atmosphere. I’m too lazy to calculate but landing from a Jool orbit on Tylo and then Vall and then into orbit around Jool again is probably already at the limit of a LV-N Nerv rocket.
yea, after a couple hundred of hours of KSP and being able to do a manned eve return it feels like one has beaten the game. Then one sees Bradly, Stratzenblitz, Turbopumped, Hazardish and: O_o Feels like one has just gotten the basics and now can really start to learn the game 😅
Almost. Check out his minmus rocket. Use mun assist to go around kerbin and eve multiple times to go for jool for free. Jool can well eject you out of kerbol. 900~ m/s interstellar

Personally, IMO automation is fine depending on the method, but is that the only way to do it? What about using a timewarp mod to get faster phys warp?
Faster phys warp won't work. His craft have a lot of parts so he isn't even able to run them at full stock speed. In most cases, faster physics warps only work for speeding up maneuver nodes.
Because the ion engines have a horrible TWR which literally sits around 0.1-0.2, meaning that instead of one short burn for circularization or changing your orbit, you'll need several dozens of burns, each burn executed at the perigee/apogee for maximum effect. Because of the low TWR, these engines literally burn for real-world hours until you reach your orbit (check the ingame clock, achieving his kerbin orbit alone took him nearly 7 years. Now remember, even though he could technically timewarp from burn to burn, the real timesink here is the burn time for those ion engines, and you can't timewarp during a burn- hence the need for automation
I just made it to Laythe for my first time today, with around 10k Delta-V, and watching this I'm impressed as all hell. (I also didn't even return, I just made believe that it was always Jeb's dream to sit in a pod in an ocean of Laythe forever)
I......I......I.......I'm speechless. I have seen "bullshit"....I've seen hacks.....I've seen "cool story bro...."....but this is none of those. I think I shit my pants a little. If you ever look back one day and say something like "I wasted SO much time in KSP when I was young" please don't. You inspire so many of us to think WAYYY outside the box. I am a better man for the things you have taught me. Thank you for this. Keep doing what you do, brother.
Bradley... Engineless(conventional or drainvalves) SSTO to Eve and back.. Ive gotten to Eves surface, but couldnt take off with my miniscule thrust of a kerbal on a ladder.
WOW you are the first one that uses nervas inside rapiers!! A lot of YTers do just aerocones, I thought I was the first one. Congarts man! Glad about this logic marriage we have in common
Also about the ion engines, i could not decypher from the video but it's good to tell that 2 atomizers support 1 ion engine and it's useful to have them as range extenders without any need of excess battery banks.
You don't need to calculate much you just keep experimenting. One way I used to do it is make a simple craft and enable infinite fuel cheat to measure the amount of delta V you would need, and then you build an actual craft that meets those requirements. As for the gravity assists, once you actually understand how they work it's not hard to just eyeball which angle you need to come in from to maximize the gains, and then it's just a matter of waiting decades in space for the correct alignment.
@taehwan jang I remember someone went to jool with 10 ton rocket, but I can't find it now for some reason. I believe it was Bradley Whistance. upd: yeah, some of "Odyssey by Bill" episodes are now not available
I have a few questions lol - how many R.A.P.I.E.Rs are there in the ssto? - how many Nervs are there? - how many wolfhounds are there? - and how much does this thing weigh? Edit: - and how do you get kerbal engineer to work? Is it because u play in an older version?
I think that automation of these huge burns is perfectly fine, because at this point the amount of patience they take is akin to torture. As long as the mission would still be possible stock, automation is fine
For Eve, one thing I've thought about is an electric propeller driven aircraft to get the vehicle out of the deep parts of Eve's atmosphere. You'd probably have to make it so that the props fold in when not in use, though.
Using an interstellar mothership craft, with autostability and contrarotating artificial gravity rings, and 100,000 m/s of delta-v... Just tk get to orbit and back
How did you do that? How did you not crash at 17:24 (safe altitude of one meter)? A tight turn at 30 meters... You are so amazing. I'm so far behind you in skill I don't even know what you might consider doable, since you routinely seem to do things I didn't think possible. Sorry I needed to fan-boy a little. Thank you for the entertainment, and for pushing the limits of what is impossible a bit further.
How con you see your trajectory this far? Bc usually one can only see like 3-4 SOI changes Ps. Another challenge you could try is to make a grand tour ssto except eve. Glhf
WOOOOOW!!!! single stage + maths! love every single part of this mission! ps. I was trying to explain the relations with aviation and air pressure/drag to my wife while I watched this video. She does not share my passion for these things but she kept the enthusiastic face throughout the whole thing :D Awesome video man!
I think I would accept using kerbal OS, it adds only very small parts and the output only effects the controls you already have access to. It would be like setting up a robot to play the game with the keyboard and mouse, except in game and you have to code it. There’s the sticking point though, you have to code it.

So basically the secret of super good SSTO's and light mass crafts is gravity assists
