Never clicked this fast on a video before, Keep up the good work!

[@Lewy94999]

Wow, you're fast. And thanks.

[@alverro5351]

I am s p e e d. Love your vids dude.

@@Lewy94999 what launcher is that? Looks like a falcon heavy that fucked a delta V Also why does the lander needs a bio shield? And what material PDFs you read that you get inspiration for those spacecrafts?

[@Lewy94999]

@@lil__boi3027 This is the launch vehicle: i.imgur.com/zzBarRN.png . It has nothing to do with Falcon Heavy or Delta IV (there's no Delta V :)). The lander needs to be bio-shielded due to very strict Planetary Protection rules for Europa. We don't know if there is/was life on Europa, so it's safest to assume the most cautious approach. If any bacteria survived the trip from Earth (not impossible), then they could contaminate Europa's surface. The mission is based on JPL's proposal for Europa Lander, though I scaled down their behemoth 16 ton spacecraft to 9 tons: upload.wikimedia.org/wikipedia/commons/2/2b/Europa_Lander_2019_concept.jpg.

Looked like Ganymede really wanted to be landed on with all those flybys. But in all seriousness nice video.

[@deniskus6856]

YES! This is exactly what I wanted! Rocket sounds are amazing!

You should do a manned mission to Titan! (Awesome vid btw)

Nice!!! Now we have to send a man up there 😉

probed mission to titan would be cool titan itself is just really cool

[@iceboi5983]

This is amazing. Great work! Can't wait for the real thing.

[@chadmcelroy4194]

Awesome video as always! Two questions: 1. Is this in career mode? (If so I'm very jealous) 2. Why do you use 1.2.2 instead of the newer versions?

[@Lewy94999]

Thanks. 1. Yes, this is in career mode (RP-0). 2. I still use 1.2.2, because of RP-0 (Realistic Progression 0) mod. Starting with KSP 1.3.1, the successor of RP-0, called RP-1 was released. I couldn't transfer my save from 1.2.2 to 1.3.1, because compared to RP-0, RP-1 changed or added so many things, that nothing would work on that transferred save in 1.3.1. And my RP-0 save was already at pretty advanced stage at that time, so I didn't want to start over in 1.3.1.

[@ScienceRules118]

Any plans for future KSP things? Seeing you do something like the interstellar missions other KZbinrs have done would be neat.

[@voidcosmos9601]

Coooooooool! Really awesome!

[@Katniss218]

That's one chonky launch tower.

[@Lewy94999]

Be careful who you call chonky. That thing remembers the first Apollo launches during 1960s.

[@Katniss218]

@@Lewy94999 No it doesn't. The original LUT wasn't 500m wide :D

[@Lewy94999]

@@Katniss218 It only seems that big because of tiny, kerbal scaled buildings. That barn, which kerbals call VAB, can't even fit a real scale Atlas V.

[@Katniss218]

@@Lewy94999 Maybe I'm just too used to seeing SLS builds from you. It's very short too, which messes with the scale. But just to double check, are these platforms 20ft apart? (lower 2 were 30ft, with upper 18 (or 16, I don't quite remember), 20ft)

[@Lewy94999]

@@Katniss218 I haven't measured it, but it should be close to real scale size. And the upper half was cut from it when it was modified for Saturn IB class rocket.

[@harrisongilbert]

Wait, did the lander fail or was it supposed to run out of battery power that quickly?

[@Lewy94999]

It was planned, I only gave the lander 6 days worth of batteries. I should have given it more, for comparison NASA's Europa Lander will have 21 days of battery power.

[@sayingROFLisgay]

@@Lewy94999 are there reasons other than weight that folding solar cells couldn’t be used to significantly extend that? Or did I miss em?

Have you considered doing a RO tutorial series bc Ur very good at it clearly and i can't transfer to ro without help, of which there is little online

[@cntfinkvaname0]

Awesome! I'd it possible in KSP design a drill you could take with you next time? Would be awesome to see

[@Lewy94999]

Not possible.

[@Matthew35333]

Such missions would greatly benefit from the use of RTGs. Now every Discovery mission proposal can consider RTG use in their spacecraft. Solar power is more than adequate for an orbiter, but that lander could really do some interesting science with mission lifespan of years, similar to Mars rovers. This mission does not lack the budget or scale, and you're sending tons to TJI anyway.

[@Lewy94999]

The lander landed on Europa's surface. This moon is blasted with radiation because it sits inside one of Jupiter's radiation belts. Even if the lander had RTG for power generation, there's no way it would last even a year on the surface. All its electronics would be fried long before. Also every kilogram counts on a high delta v mission like this, so there would be no point in bringing a 100 kg lead radiation shield on a ~400 kg lander.

[@desmondshepard3823]

14:25 meteor impact?

[@Lewy94999]

That's the deorbit stage.

[@mariasirona1622]

Ight, gonna do this with Vall

[@raulpalomino9472]

Wow! Amazing. @Scorpu, did you plan all those flybys ahead of time prior to launch? or got advantage of "what you had" once in Jupiter orbit?

[@Lewy94999]

I took advantage of what I had after Jupiter orbit insertion. Those moon's orbital periods are short, only several days, so it's pretty easy to accomodate without any planning.

You can press Alt+0, navigate to CityLights tab, and press apply to temporarily fix the ugly cities bug.

AMAZINGNES!!!MORE!!!

[@jacko4932]

Question, If you can add Other solar system mods would you send manned missions to them?

[@Lewy94999]

I can't add other solar system mods, because they work by adding a central body (usually a black hole) around which normal KSP stars orbit. I have a lot of probes in transit in heliocentric orbit and their trajectories would very likely be screwed up by adding more solar systems. Also it would almost double the number of celestial bodies that I have in my game and add several hundred MB worth of texture files. This isn't very good for game stability and I'm already at the upper limit of what I tolerate in terms of how frequently the game crashes. If I find a way, I would rather launch a probe mission to a habitable exoplanet, something like the mission to fictional Darwin IV planet from Discovery Channel's 'Alien Planet' documentary. I think that manned interstellar flights are centuries away, even with state of the art fusion drives it would take decades just to reach the nearest star systems.

[@gooncaveenthusiast]

What happened to all your older videos? The saturn one in particular was super cool

[@TechTekker]

This is awesome! Is that how the engines really sound in the game?

[@Lewy94999]

Thanks. And engines don't sound like that in game, I added the sound while editing the video.

[@TechTekker]

@@Lewy94999 ah, I thought so. Mine certainly don't. But I considered that you could be using a rocket sound enhancement mod

14:15 deorbit stage: uh oh, second impact :/

[@sagarmodi415]

What engine are u using for 1st stage

[@Lewy94999]

Each common booster has a single F-1B (with gimbal locked) and four modified Merlin 1Ds to provide control.

[@jacko4932]

Just wanted to ask, How is the current save status?

[@anguscovoflyer95]

how could its orbit decay by itself when europa doesn't have an atmosphere?

[@Lewy94999]

Because of gravitational perturbations from Jupiter.

[@ravenclawtom]

europa does have a thin atmosphere of oxygen in real life. idk if thats simulated in the mod though

[@sirjeffels4020]

You should have added an RTG or at least a tiny solar panel to the lander, that way it can stay alive for a bit.

[@Lewy94999]

There's no point in doing that. Europa's orbit lies well within Jupiter's radiation belts. Electronics of any craft that landed on Europa would be killed by ionizing radiation within 1 - 2 months. It's better to lower the lander's mass and complexity, rather than add a power generation system that would stop being useful after 2 months.

Are you sure you can do this with only a Delta IV Heavy? Without any slingshots to get to the Jovian system? I thought it required at least a Falcon Heavy?

[@Lewy94999]

That's... not Delta IV Heavy lol. This is the rocket I used: i.imgur.com/zzBarRN.png . It's more like Falcon Heavy with hydrolox second stage.

[@robertclark1734]

@@Lewy94999 Thanks for the clarification. Perhaps you could do a Falcon Heavy version using, say, a Centaur as the Earth departure stage.
