Thank you so much for making these videos. I’m a somewhat “nerdy” 14 year old and I absolutely love rocket science. I tried out KSP and found that getting better at the game is rough so I sought out assistance on TH-cam. I just want to say that your videos have been immensely useful and engaging and I just wanted to let you know that the work you’re putting into your videos is greatly appreciated! Thanks!
As someone who’s played KSP over a thousand hours and watched countless hours of YT videos, I can affirm this is one of the best, if not *the* best in explaining the physics (especially the “Let’s Do The Math” series) as well as practical application/demonstration. I wish something like this existed when I was 14. Kudos to you for learning it. Never stop learning.
Definitely check out his do the math series. It is going to be difficult at first but it is really good to have a deep understanding of it. Although you may never be setting up orbits for satellites (or you may who knows) it makes learning a lot of more complex mathematical concepts a lot more enjoyable to learn because it's interesting vs a dry burnt out teacher half assing stuff. Its a good idea, plus when things click it is really cool to think about just how things work.
Mike, Because of you I just landed my first ever crewed mission to duna, and actually managed to return it this time unlike the.... other time..... Besides that I wanted to thank you soo much for making this amazing content. Keep it up!
Just been doing some missions on Duna i found drogue chutes to be very useful when you dont have the perfect decent,rushed. They will slow you down enough so that the main chutes can open. Typically you will coming in a lot faster.
I know im late to the party. But thank you for your videos man. You make the game so much more digestible, and more fun because of it. I can now identify mistakes i wouldnt have been able to otherwise. Like the one im about to make. I have a relay station with 2 satellites that im going to connect to a control tug and a lander. Im then going to attempt to take the whole train to duna and set up a comms network and make my first landing as well as return. On 5 nuclear engines 😂 Quicksave, you're my best friend 😂
@@MikeAben had time before work to rendezvous the two halves. Going to attempt the burn tonight. I watched your video on the oberth effect so I can see me needing to use that technique of slingshotting orbits as the craft is so big.
To get the phase angle between planets, I just use an actual protractor and measure the angle on my screen. The mod KER shows it in the tracking station but that's the tracking station, which is a bit of a pain if you are piloting a vessel.
Watch a video from Mr Aben: "Dude... I know how to get to LKO... Hum.. ok I didn't know that little detail... Good to know I guess" Watch another video: "Wah... I have been playing 700 hours on Steam and... I did not know that. And that Really simplifies it all" Watch the 10th video in a row: "H-How do you only have 13k Subs... you even answer questions I did not know I had.." Thanks a lot for this 47 videos playlist... It's the clearest series I've seen (And one of the most up to date!)
While the number of parachutes on the lander made the touch down velocity well within the safety margin of the landing legs, in general if you land in a valley/canyon, you will have both more time in the atmosphere and denser atmosphere which will allow you to land heavier vessels or with less parachutes. I have only landed a half dozen or so times on Duna, so I don't have extensive experience, but I found that the centers of canyons are generally about as flat as Duna gets.
"We are gonna retract our ladder" - proceeds to deploy the ladder hahahahahaha Apart of that, thank you for making this kind of videos, they help me a lot with KSP!
Great video Mike. It's funny how we all have our own way of doing things. For example, you landed, did whatever had to be done on the surface, and then raced off back into space. Me on the other hand, I tend to keep the crew on the surface until about the day before the planned departure from Duna when the phase angle's right to get back to Kerbin. I think I remember someone from the space industry saying that if we ever do land on Mars, it would be safer for the crew to remain on the surface, rather than spend months on end in orbit, waiting to begin their run back to Earth. I'm curious, and yes, I do have Window Planner installed, but I do like to try to understand how the maths works behind all the mods; you said we can calculate when the planets are at the right phase angle to make a transfer, how would you do that? Maybe a future Let's Do The Maths video there, eh? Anyway, terrific job as usual there mate.
Yes, staying on the surface makes more sense, but in a tutorial made more sense to separate the discussion about ascending and getting home. I am currently working on a math video on calculating phase angles. The post date for it is the first Saturday of May. There's another tutorial coming out before that.
Staying of the surface is safer in large part because the radiation environment is safer on the surface. Additionally, the gravity makes living and staying healthy easier, in situ resource utilization is possible, and while not related to safety, it would allow more science to be done.
hey dude there's either something wrong with the phase on your microphone, or with the sound compression in your video. Check it out cause the quality is pretty alright it just makes it sound low quality when wearing headphones. Thanks for video!
Awesome video. I have a mission enroute to Duna. I’m going to land, then rejoin a tanker in orbit that will have extra fuel, then go to Ike before going home. In using the technique discussed at 17:33 will it work the same just lining up ship, sun, and Ike? Or do I need to include Duna in the alignment? I have Transfer Window Planner installed if all else fails. But, I’d like to try a more seat-of-the-pants approach. Also, the ascent profile is excellent. I had practiced/simulated on a sandbox save and tried doing it like Kerbin (being about 45 degrees pitch at 10km and time to Ap approaching then maintaining 1min). But, it seemed, subjectively, too shallow and I was spending too much time in the atmosphere. This technique sounds great. Can’t wait to use it. Lastly may I say.... *FIRST*
It should work the same way with Ike (no need to include Duna in the alignment, though honestly, I would just use Window Transfer Planner as you already have it installed.
Just to add, ejecting from Ike for Kerbin is a bit trickier. Remember you want to leave Duna's SOI going retrograde relative to Duna's direction around the sun. Ike is moving in the direction you want when it is between Duna and the sun. Then think about where to put your ejection burn from Ike to add to this velocity.
I wonder... if I send a giant ship to Jool and it doesn't have enough gas to get back to Kerbin in one tank, a) which moon is the best (lowest gravity) to send a fuel lander to with an ISRU kit, and b) should I send the lander twice to get a full tank of ore to use later if I wanted to take the mothership somewhere else?
@@MikeAben thank you very much! I didn't know about that. I just searched it on Google and guess what you had an awesome video tutorial about this. Thanks!
I've had this happen a couple of times. I've gotten quite good at docking about another planet thanks to my habit of just building separate vehicles for return. All that docking has me getting ready for my first duna space station.
I tried a 83* angle as you did in the video (return to kerban orbit, from Duna) and also tried 75* but im well off the mark, what am i doing wrong?? also using a gravity assist from Ike as I don't have enough ISP, (through the scenario mission Rendevour from Duna)
-75 degrees is the correct phase angle. Make sure it isn't positive. The negative means that Kerbin has to be behind Duna in its orbit. Using Ike for a gravity assist makes it much trickier to set up. Remember your ejection from Duna's SOI must be in the retrograde direction relative to Duna's orbit. You'll need to get Ike in the right position for this to work. It'll take a lot of fiddling.
Ok thanks im trying to make one similar to what you made. I'm on console and wanted to be sure mine is as close to the same as yours. Thanks for all your videos man they been a really big help to me, and you do it where ever I can understand lol.
If you're lucky, the plane of your orbit will be close to perpendicular to the sun at the transfer window. If not, the ejection may take a lot more dV (combination of normal and prograde). You may want to consider changing your orbit if you can. Ike may be able to help with that.

After so many years of playing... after this playlist i finaly understood it. Thank you Mike. You are a Hero to our Community.
Thank you so much!!!!! I was able to get an encounter with kerbin, and land with just 23 delta v left, you're a life saver!
I’m not the greatest at this game but videos like this make the learning process just that little bit easier. Thanks for the video!

Thanks man I dropped a sub. Really appreciate it took me so long to do my first Duna return mission

The next one is in response to a lot of comments and is about dealing with flipping rockets. After that will be a math video on phase angles.
Great tutorial :)

That was best dude! ¡!!!!!!!!!
And how do you have that much gas im building the same lander and it gives me 537 m/s
Make sure the dV in the VAB is set to vacuum.
I wonder... if I send a giant ship to Jool and it doesn't have enough gas to get back to Kerbin in one tank, a) which moon is the best (lowest gravity) to send a fuel lander to with an ISRU kit, and b) should I send the lander twice to get a full tank of ore to use later if I wanted to take the mothership somewhere else?
Pol is the smallest moon about Jool.
What part did you use to be able to place the docking port on top of the parachute on the landing ship's top tip?
I'm just using a fairing base with the interstage nodes turned on.
@@MikeAben thank you very much! I didn't know about that. I just searched it on Google and guess what you had an awesome video tutorial about this. Thanks!
Thanks for the help but when i try to return to the command pod, I don't have enough Delta V to orbit and dock. What do i do?
Turn on infinite fuel in the settings or send a rescue craft.
@@MikeAben That's what i actually did
I've had this happen a couple of times. I've gotten quite good at docking about another planet thanks to my habit of just building separate vehicles for return.
All that docking has me getting ready for my first duna space station.
I landed at Duna to only find out that my modded command pod cant be opened to so EVA for my Kerbals...
finally landed on Duna and returned home
I tried a 83* angle as you did in the video (return to kerban orbit, from Duna) and also tried 75* but im well off the mark, what am i doing wrong?? also using a gravity assist from Ike as I don't have enough ISP, (through the scenario mission Rendevour from Duna)

@@MikeAben thanks for the help man! :) great video by the way
What's the TWR of that lander pls? Better yet what is a good TWR for leaving duna
It has a vacuum TWR of 0.72, and 2.27 on the surface of Duna.
Ok thanks im trying to make one similar to what you made. I'm on console and wanted to be sure mine is as close to the same as yours. Thanks for all your videos man they been a really big help to me, and you do it where ever I can understand lol.
This looks just like the Artemis program but in duna
When the flag looks kinda sus
the alarm clock LIED to me! (srsly good tutorial tho)
I have come to learn the stock alarm cannot be trusted myself and always quicksave before timewarping now.
I managed to get into a polar orbit around Duna. How do I get back from there?
If you're lucky, the plane of your orbit will be close to perpendicular to the sun at the transfer window. If not, the ejection may take a lot more dV (combination of normal and prograde). You may want to consider changing your orbit if you can. Ike may be able to help with that.
@@MikeAben Thanks Mike, I'll give it a go
All kerbals safely home. Thanks again
What is the part on top of the can i cant find this
It's a fairing with a docking port on top. You need to turn on interstage nodes to make it work.
When you make these tutorial videos, do you use mods?
No. I've deliberately kept all these tutorials mod free.
What engine is on the lander?
That is a Terrier engine.
I would rather land my probe on the moon
Then why did you click on a duna mission?
