- Back in the day of KSP 0.9 I built an epic rocket able to to to the Mun and back in under an hour, but 1.0 nerfed the rocket thrusts and ISP, and added in deadly reentry effects. After building a 7000 part rocket massing 127,000 tons I spent 2 hours boosting it up to 8km/sec before completing the run on a livestream.
(apologies for the bad audio, at 1 minute mark, not sure how that happened, it does fix itself).
I should have checked my Staging www.bonfire.com/check-yo-stagin/

The shortest distance between two points is a straight line... with a suicide burn at the end and some unintended explosions in the middle.
Jett Quasar the earth changes the curvature of space-time and thus we are not working in Euclidean space so the shortest distance is not a straight line
It depends on your frame of reference. Also note that moving at relativistic speeds will decrease the distance between two points even further.
And with a wormhole the shortest distance is always 0 ;)
Since both bodies are moving, the path will not quite be a straight line...
But of course, the optimal in terms of time is accelerate half the distance, decelerate the other half...
... Except in a rocket, because so much of your mass is fuel, the optimum is actually a massive impulse burn that burns as much fuel as possible in as little time as possible....
Ehhh. Too complicated. XD
Damian: Euclidean geometry only applies to planes, so while a straight line is impossible on a planet (technically, works just fine from our perspective) in space you can treat yourself as on a plane by ignoring the third dimension. Some adjustment of your orbit might be required though to get into the right plane. I'm tired of people saying Euclidean like it means something. It's a set of 5 postulate for lines on a plane.
Furthermore, that's not how gravity works. The way that it curves space is that you fall toward the object. For all intents and purposes it is just a force. If you have enough thrust you can just go in a straight line in space, more or less. At least if you lead the target properly. Maybe some slight adjustments here and there.
Kuralthys: What you said regarding acceleration is accurate if you aim for empty space, but if you want to land you also need to save enough to fight the gravity.
Every time Scott briefly touches a planet (Or moon) before launching off back to space made me imagine a UFO landing on Earth with crowds gathering around just to boop the ground and take off again.

yeah he could at least walk up and down making 'beep beep' noises,

Pretty sure if this were real life it would lower the fps, too.
Actually the area nearby the launch pad would be full of smoke
Golden joke

No pun intended
So we are living in a simulation after all. Fucking Aliens can't even programm rigth.
In real life we also have a pixel, the Plank lenght.

Mic audio boosts a ton @15:55
Really sorry about that....
I love these ridiculously titanic rockets. You should have a second absurdly colossal rocket waiting on the mun so the command module can dock with it and then instantly blast off back to Kerbin. Think we can get the Kerman on board pinned to his seat for almost the entire round trip journey?
I am new to KSP. The idea of your groundbreaking liquid fuel rocket booster was amazing power. Wow!! I immediately imitated it and incorporated it into the first stage rocket.
Was glorious to watch you do this on stream. GG Scott.
Really enjoying these videos

How about a challenge for the fastest orbit around kerbin? I wonder how much faster than a normal orbit you can get.
no pun intended
Um, that's what he did at the end of the video -- you *did* watch the entire video, right? (Answer: 1 minute)
M Reed No, i did not mean the time to orbit. What i mean is the time from flying in orbit to getting back to the exact same position in orbit after surrounding the planet. For example, start above the north pole, fly over the south pole and back to the north pole (launch and landing not included, time starts in flight).
so you weren't joking. the orbit speed is fixed for an altitude. if you thrust prograde, your orbit goes higher.
unless you thrust at an angle inclined towards the planet center...
The problem with that is that an orbit with a higher velocity means you need to be closer to the object you're orbiting; adding more speed just makes your orbit elliptical. On Kerbin and other planets, you can only go so low before you hit the atmosphere. On the Mun and other bodies without an atmosphere, you can only go so low without hitting mountains.
15:54 Holy shit you spooked me with the sudden spike in volume!

"Its full of boosters" 0:39
Clever.
Excellent Quality MOAR BOOSTERS
No pun intended
"My God, it's full of stars" is a famous line from the Kubrick classic "2001: A Space Odyssey". I believe the line wasn't actually said on screen until the sequel ("2010..") but that's not important. Scott's line was a play on that.

Augh, the ADR blew my ears out. I trusted you Scott!
I really miss a "hello it's Scott Manley" at the beginning of a KSP video.
that fairing made definitely sense, aerodynamically
What a great build, no pun intended.
iirc it's not explosions, it's rapid oxidation.

Our House rules for Mun and back racing(lan party), must land on landing gear, must be stable (5 second landing wait) landing back at launch center, must be actually survivable. (Glimits must be on) can't die from G's parts and kerbals or heat. Much more of a challenge. :D
Can't wait to see this in KSP 2
phooey on your fancy liquid rockets. It's solids or nothing!

SCOTT DID A SWEAR :O
could you do a video explaining/demonstrating suicide burns?
That was pretty cool. No pun intended.
Ive beaten this. 5 Minutes to mun 3 minutes back. ALL stock
Real time or game time?
Rumor is that Scott's CPU melteddown so hard it is still melting through the ground on it's way to china. Lol
If you take a large tank, you can put a single vector in the middle and then with 6 part symmetry place 6 more around it creating a 7 booster cluster instead for the stock 4. Needless to say, it’s more powerful and easier to control, if it’s not “lagging”.
love the rawhide lyrics.
Yeah. People should indeed watch the Blues Brothers. If for no other reason than for the youth of today to see who Cab Calloway is, and likewise, what class looks like.

Fun fact. Had they done that that for Apollo, they would have saved the mass of a toilet. No pun intended
Lol
Why did you write in the video description “to to to”? I don’t understand. Please explain.

Hey Scott. What happened to the rest of the Going Nuclear videos? i was really interested in those..
Oh dude so close!
When doing an airbrake but not fully de -rbiting could you use the planet's rotation/wind to alter the angle of your orbital plane without spending fuel or do you think the fuel spent recovering the speed lost in the airbrake would always outweigh the delta v saved in the free orbtal plane change?
+willis936 this is called an aero assisted plane change. It’s not clear the savings work
I thought about this for a bit.
If you're already in low orbit, it doesn't take much delta-V to intercept some atmosphere for your wings to work with. To make it worth your while, you want to gain more change in direction than you get reduction in velocity, in other words, you want more lift than drag. It's not hard to make an airfoil with a lift-to-drag ratio of 10 or more, but that's at subsonic speeds, not hypersonic ones. When you're moving at mach 27 or more, an L/D ratio of much more than 4 is probably impossible. That still sounds like it might be enough for our purposes though.
So you do a small retroburn, dip into the atmosphere and start turning with an L/D ratio of 4, so far so good. What happens when you finish your turn? You point your nose prograde and stop getting lift. This reduces the drag you get, but it doesn't go to zero, reducing your effective L/D ratio over the whole maneuver. You can solve this either by very carefully calculating the size of your 'dip', or by splitting the maneuver over multiple orbits. This might be a good idea anyway so you don't overheat your spacecraft. Don't forget to fire your engine to counter the drag while you're doing this or your apoapsis might enter the atmosphere. And fire again at apoapsis of course, once the desired plane change has been achieved.
To perform this maneuver, you need wings, and as we saw, they need to be good ones. The space shuttle had a hypersonic L/D ratio of 1, which doesn't get us anywhere. The dream chaser might be better, but I haven't seen any numbers on it. The wings also need to handle the compression heating from a mach 27+ airstream. It won't have the intensity of re-entry, but I don't think it's pleasant. Wings that meet these requirements are probably going to weight quite a bit. If you had brought more propellant instead, could you have made the same plane change propulsively? Maybe. It's definitely simpler though.
So is this maneuver useful? Well, if you're going to do aerobraking anyway, it you can grab a 'free' planechange while you're at it. If your craft already has wings and operates in low orbit, it might make sense. Otherwise, not so much.
Maybe try it out in KSP?
A tiny bit faster if you set the stages to decouple and ignite next stage at the same time?
I think I can do better... Are stock warp drives allowed if they take advantage of ingame bugs?
cause if so I could try sub-30

5:25 Fry and Laurie used to do "No pun intended" thing.
So far I only have one successful munar landing, I forgot the legs and had to do a thruster landing :-/
I have yet to have enough fuel for a return trip.
Damn this easy mode. I struggle to land my craft under 3000 m/s in extremely steady orbit without everything blowing up and you just suicide at 8000 m/s in a vertical landing. I guess later versions got more realistic and complicated in regards to that since I can remember it being that easy before.
You are insane xD
concentration intesifies indeed.

MOAR BOOSTERS
8202 meter per second when the game crashed... thats 18k miles per hour. thats about mach 24... thats how fast the meteorite was going that killed the dinosaurs.
Still only half the speed of voyager 1...
Is the goal to reach 0 velocity on Mun or just touch it? A route that uses Mun's gravity to swing back around while just barely glancing off the surface while still at a high tangential velocity might save a lot of delta-v.
Jebediah Kerman aproves this design.
What about Piper Kerman, or Magte Kerman?
Suicide burn distance change seems to coincide with navball auto-switching between orbit and surface mode, could it be connected?
Well spotted. I'd say yes, because Flight Engineer is now calculating the suicide burn distance/time with respect to your surface velocity rather than your orbital velocity, hence the big jump in the numbers.
What happened to galileo conquest? No pun intended.
[Outsider looking in... DO not shoot the Messenger]
Although its starting to look like it, you have a long way to go before you've got The Sunprobe Rocket... [yup.. showing my age there ]
Suicide burn... you mean how I usually land things?
I did to the moon not back 1:30:00, I just did asparagus staging with vectors, then Evaed 20000 meters above mun then ya
I would like to see a von Neumann probe challenge
Here is a idea. What if you have a ring of boosters on the Mun. You then aim for it and land in the center of the boosters. Then dock with the booster ring and take off. That could give you extra trust coming back.
This is how Hollywood movies understand space travel actually.
Shut up CPU, we are using more boosters!
I Love you scott manley
The peak g force was lower? What am I missing? Valentina was getting killed at 16:29 :O
Standard NASA hiring procedure
2:59 Why does that look awfully similar to the Death Star?
I like how you had to explain to your viewers that the far side of Mun is in fact, further away.... because of planets being curved.... no fucking shit
Does speedrun on livestream. Doesn't time it. Great stuff. :)
+sixstringedthing game has a clock built in!
Scott Manley of course it does, but typing "Does speedrun but forgets to pay attention to MET at crucial moments of play" felt a little unwieldy. ;)
Thanks for flattening the KSP learning curve for us relative beginners.
why don't use obs instead of bandicam?
