Kerbal Space Program - Minmus & Back With Less than 2 Ton Launch Vehicle

[@scottmanley]

Minmus is the easiest target, sure it's slightly harder to get to than the mun, but when you account for the fuel needed to land and the lower gravity Minmus is the best destination for the newbie pilot.

[@CyberPitz]

I just want to say thank you. I went from a guy who couldn't even build a rocket that could get to orbit to having landed on, and returned from, Mun and Minmus. Your tutorials are absolutely amazing and you're very good at explaining things.

[@scottmanley]

The LESS concept was the original Kerbal Space Program. Especially the early proposals that had astronauts leaning side to side to steer.

[@scottmanley]

Well you can figure out how much radiation is emitted using the stefan boltzmann law, and a typical estimate of the suit's surface area (1-2m^2) - radiative emission is of the order of a few hundred watts, which is more than the heat production of a resting astronaut.

[@Paganinifire]

that is the most efficient under 2 ton spacecraft i have ever seen, SCott your spacecraft is awesome!! seriously didnt think you were gonna make it back for a split second!

[@scottmanley]

Whenever I make a video I record realtime commentary, then when I'm editing I keep some of it and record new bits, so a lot of the videos include realtime bits. Generally it's hard because there's lots of 'boring' bits, and I want all my episodes to be 10-20mins.

[@Blakackmann]

V is the physical sign for Velocity. Delta marks a change in a vector size. So its the amount of Velocity you can change, when fuel burns down you can change less of your velocity...and so on.

[@caracaes]

About the craterless surface of Minmus: A quick especulation could be that the planet is composed mostly by low fusion point metals (very unusual, but not impossible) and as meteors hit the surface, the metal melts and closes the crater. The heat of the sun combined with coriolis effect could also cause smoothing of the surface.

[@TheSpacecraftX]

V is velocity and delta (represented in physics by a sort of triangle) means change in. So delta V is change in velocity (or speed if you want to call it that) just like delta T is change in temperature. Delta V is initial velocity minus the final velocity.

[@klovasoszenovka]

I dont know any crafts that can land in water and take off again however in the tracking station there is a "reover" option for any crafts/kerbals landed on kerbin.

[@antonremlap2168]

i tried to land on the mun, i ended up orbiting the sun

[@budthespud3226]

For a moment there I thought he didn't make it. Those Kerbals are made of sterner stuff than we thought. Nicely done Scott. Proving you are the KSP Master.

[@scottmanley]

It's terribly impractal, but it does resemble the LESS - lunar escape system that was designed to lift off from the Moon.

[@DanieleGiorgino]

That was a very entertaining video. I love how you push the limits of what's possible in this game.

[@TheLivirus]

Thanks for the help. I'm confident it would have survived the landing. The shuttle was descending very slowly using 1 big parachute and 3 radial ones, and it was not heading for solid ground but an ocean. The debris I left in orbit showed up in the tracking station but not the shuttle. Oh well, I guess the trick is not to eject a damn a kerb mid-air hehe.

[@goosetown-47]

I say this with the greatest respect and having a deep scottish roots of my own. You sound almost identical to the new Scotty in Star Trek.... :) Awesome tutorials.

[@lankey6969]

Great video Scott! As I am no good at this game I really enjoy watching you play and make it look so easy! How about doing the exact opposite for the next video, the most weight you can possibly send up at once! Thanks again for all the entertainment!

[@Illakune]

Crazy Scott Manley Strikes again! YOU'RE BRILLIANT!! Love your videos

[@GeekControl2MajorTim]

Watching the Kerbal re-enter the atmosphere headfirst, basically taking the atmospheric entry burn to the face, that is where I cracked up.

[@MinecraftYear]

Any mission you can walk (or swim) away from is a success. Great video, I wish I was half as good as you.

[@quantumac]

Those Kerbals have some tough spacesuits, rated for reentry and high impact!

[@Lepikko]

After seeing this I can't stop imagining myself orbiting the moon in a space suit surrounded by the emptiness of space :D Great job again!

[@jamesjackson4210]

5:25, scott is so obsessed with being an astronaught and kerbal space program that he plays the game in a home made space suit

[@TheCOREFury]

That must hurt when reentering the atmosphere :D

[@RedsBoneStuff]

NASA needs to see this and learn from it.

[@cranialtoxicity4434]

We don't have a tiny, frozen, second moon with a simplified and unrealistic orbital trajectory. So I don't think there's much to learn.

[@telecorpse1957]

Also our jet engines can't propel themselves to nearly orbital velocities.

[@gibsonberg7854]

If the kerbal is close enough to the shuttle, just hit one of the bracket ([ or ]) keys to swap crafts. Also about it not showing up, time does take place while looking in the Tracking Station so unless you were far from landing the ship MAY have hit the ground.

[@itsmeian17]

The reentry effects made my day, using his head as a heat shield.

[@Zeeky64]

What an inspiration for Kerbals everywhere!

[@AsherGames]

Thanks for posting this. Your videos are awesome and do not get old. If only I could fly safe.

[@Dxpress_]

No.......REALLY!? I never would've thought. You sir have just blown my mind forever.

[@freddanster]

"Hello! It's Scott Manley here" always makes my day :)

[@MrDarthImperius]

Performed a completely insane and dangerous mission. Wishes you to fly safe afterwards.

[@Chlorate299]

Funnily enough I did that calculation at work earlier...assuming a human to be a 2m tall cylindrical black body the radiative heat loss to space would actually be nigh on a kilowatt. However EVA suits are rather well insulated with several layers of aluminised Mylar to prevent excessive heating or cooling through radiation by giving the suit a very low emissivity.

[@enderslayer99]

scott, your the best, around nothing's ever gonna keep you down (well this is true)

[@Kairikiato]

Really enjoy your videos mate, also i have scottish grandparents so the accent always brings me back to the perthshire moors

[@qcumbers23]

"Fly safe" As he sends a Kerbal' headfirst into atmospheric re-entry.

[@BlackStar2161]

Change in velocity. For example, if you have a rocket with 800 m/s delta V, then you can increase or decrease your current speed by 800 metres per second if you burn prograde or retrograde.

[@AtlasJKB]

Sometimes, when my station doesn't get an encounter, I lay down and cry...

[@kwinvdv]

Now what is the smallest mass to say Duna. I think you can exploit the fact that the EVA fuel refills after you enter a pod (the chair does not however) and use that to theoretically give you infinite delta-v, however with a very low thrust to weight ratio, so you would still need a stage to land (if no atmosphere) and take off.

[@scottmanley]

So, are you going to see 'Gravity' when it's released then?

[@armedtoe]

I sound like an utter madman telling my friend about this video. Long ago, I made the joke that I would try to get into orbit with my jetpack. Only a Scott Manley could ever actually pull it off.

[@Limivorous1]

God damn, this man has some skills / knowledge.

[@scottmanley]

It is a Mystery.

[@nicolaporcu1]

A mini orbital map near the navball might be very appreciated by the community.

[@ToMeTheFool]

Stock rockets are okay... I got some from the FASA historical mod, and they perform beautifully.All craft are from the Gemini Program.

[@als19981]

you're right, delta means value 2 minus value 1. In this case the values are your velocity, thus delta velocity, so it is velocity 2 (after you increased it) minus velocity 1 (before you increased it) :)

[@standdbyme]

The video proved that our Scott Manley is still the boss of KSP.

[@Tuxfanturnip]

At 10:30 I can imagine him being like *Taps controls* "Mission Control, do you have the instersect reading?" "It's 2.4 kilometers." *Taps controls* "What is it now?"

[@upgoon4015]

always thought about the same thing, never new there was a moving coming out about it, going to have to see it now

[@Chrischi3TutorialLPs]

hey scott! i got back from the mun to kerbin by ONLY using the eva pack. just needed a high enough point.

[@TheDutyPaid]

I still have a lot of trouble just getting in to space, then I watch Scott do this -__-

[@123callumrox]

dont worry your not a noob for not knowing this because its real rocket science and it took me ages to figure out what its is. i had to look up alot of things to fully understand it

[@Mojobojo]

Its no longer a mystery (maybe). I just tested it, make sure your nav ball is activated in map mode before you EVA into the seat to takeoff. When I started my game I got out an EVAd, nothing out of my jetpack. I went back in, activated my nav ball in map mode, then EVAd back out and I was able to use the suits jetpack in map mode.

[@blitzation]

Delta V is the change in velocity (speed) so 500 m/s Delta V will change your velocity by 500 m/s

[@mitchellberg9975]

look how much practice he gets he does this to supplement income and other things, while on the other hand you do it to have fun. my friend everyone is good at some point some just get their faster getting a space station into orbit is still an achievement. don't doubt your ability.

[@scottmanley]

Well it's more a matter of time.

[@Recycled]

It's easier to land on Minmus because the gravity well is not as deep, so you won't need nearly as much fuel to land safely as on the Mun, even if it is physically further away from Kerbin.

[@andrewtaylor6293]

I'm pretty sure they are told by ground situated tracking stations. (may be wrong but I'm pretty sure)

[@Chlorate299]

Actually the only major thing inside a space suit that generates heat is the astronaut. They have considerable trouble keeping cool on space walks since the only way you can lose heat in space is through radiation.

[@falconflyer2000]

Delta V is a rocket`s ability to change its velocity. Its a calculation of the thrust, weight, fuel and fuel efficiency of the rocket. Literally, its not Delta V, its the delta sign from latin and V, which literally means CHANGE in V, which is the mathematical term for Velocity

[@browncoat697]

I was thinking the exact same thing, except I used the jetpack to do a 60km jump from one point on Minmus (where I landed the manned craft) to another (where I landed an unmanned craft).

[@101SnakePit]

How to go to minmus and back with a minimalistic and cheap vehichle and leave NO space junk whatsoever. Efficiency at it's finest.

[@RusticWolf]

You sir are going to completely blow away career mode when it's finally added into the game.

[@Monmize]

This Kerbal deserves a fucking cookie

[@Sean_735]

Jet engine, BY FAR. Unless you're in space, in which case lol no air

[@0076Kirby]

if you somehow made a really complicated and confusing floating launchpad, somehow flew it to the kerbal and then somehow took off safely, yes

[@SvetlinTotev]

kerbals are always in one piece but sometimes the different parts of their bodies are far away from each other

[@IKetoth]

and that gentleman is why its called Manley mode

[@TeamPotatooo]

It's actually only appearing to orbit Earth, because it has the same orbital period as Earth's, but it never crosses paths.

[@matthewthompson8637]

Now this guy is inspirational

[@crobochamp]

Scott, I don't know how you manage to keep these Kerbals alive sometimes. I'm sure Jeb loves you to death though. lol

[@TheRealStuntmanMike]

I want Scott's voice it's freaking awesome

[@impguardwarhamer]

I remember when I was new with ksp, my mun rockets where humongous and wouldn't get me anywhere. then I did some reseserch and built a rocket 1/4 the size that got me to the mun and back!

[@Zerepzerreitug]

Because he's the pilot that KSP deserves, but not the one it needs right now. and so will criticize him, because he can take it. Because he's not a role model for other KSP pilots, he's a KZbinr, a science commenter...the Scott Manley

[@CreeperOnYourHouse]

If you pay attention, you see that Scott replies to comments only when he wants to.

[@Keego0201]

I am super excited for that movie.

[@N3Coalition]

That movie is looking pretty interesting so far. Seems like they're going for realism with even no sound and the like. :D Though yes, pretty scary!

[@TheLivirus]

Thank you for stating the obvious. In case his sarcasm wasn't evident enough from the words he wrote, the emoticon ending the comment should be an indicator.

[@MonkeyTurtle100]

Great ending to a great video, thanks Scott :)

[@MotoMendez]

scott what i think you should do is after every mission rescue the kerbal

[@condorscondor]

and he is brilliant at it.

[@Minecraftmonkeys]

it's the change you can make in velocity. from 600 m/s to 800 m/s, you made 200 m/s of delta V

[@tavert]

I have an updated version of redd.it(slash)1hp2q5 using the new engine in the works. I may be able to get Mun and back in 1.917 tons, will be close though. Without MechJeb, 1.97 should be doable. Ladder method is lighter but more tedious than a seat.

[@DrBarnabus]

You can do all that land and take of with just the pack on the kerbals back!

[@RMJ1984]

minmus easy target *grumbles* *spends entire afternoon failing to get to minmus* man i suck lol. Not to mention YOU can do it with such a small craft, Simply amazing.

[@OmicronCrew]

i can just imagine this in the show called the jetsons

[@falconFXT2]

it's a measure of the amount of thrust that you can generate using the fuel though.... close enough

[@GrebnevNikita]

"I'm Scott Manley, and I just sent a guy to Minmmus and back, and then crashed him to the ocean. Fly safe."

[@mumatz123]

Scott could you make a video about how spacecrafts "know" where they are and what their orbital perameters (e.g. closesest approach to a planet) are?

[@zulzarax1]

did you know that earth has a second moon called cruithane in real life!?

[@TheSgfried]

Thank you thank you thank you. Found it through the first link (third for me was a youtube video that is outdated I believe). But thank you very much

[@richardman39]

Specific impulse is efficiency.. Scott has a vid about it.

[@bobbybob472]

there is you can hire him in the new hiring place and he does have max courage and zero stupidity

[@R3kolas]

I wonder if an astronaut really could make it to the moon and back on an under two ton spacecraft. Thumbs up so Scott has a better chance of answering my question, please.

[@adame5176]

Scott made gravity assists with it and went to the Jool :D

[@AmethystZhou]

That was EPIC!

[@karlmuster263]

Wow, what a suspenseful ending.

[@cmdrdisulfiram]

I would love it if Scott commented on Gravity, the movie that is not out yet.

[@maxsiege1]

Jet, but it uses air intake instead of oxidizer so it only works in the atmosphere

[@longshot789]

Could you have turned on 'fine-maneuvering' or caps-lock when doing tiny burns with your eva-rcs?
