  1. I got as far as landing on and returning from all the major bodies without ever calculating anything. Heck, I even did my Jool 5 mission without explicitly calculating the dV of anything. After a while, you just get an intuitive idea of how far you can go with what configuration. Although I did mess up going to Moho and had to send a rescue mission. Once I started getting into pushing the limits of different designs though, I started doing math both to calculate dV and to figure out how to set up encounters for multiple gravity assists. It was all just Excel spreadsheets though. I never bothered with Mechjeb or KER, as the formulas involved are pretty simple.
  2. It would probably be a mercy for me to kill my Kerbals, given how extremely long I leave them stuck in space during my endless missions.
  3. Heh, I remember that "Kessler bomb" thread from way back when!
  4. Thanks so much for the encouragement PLAD. It will go a long way towards keeping me from losing heart through this endless process of optimization. This may take a while, but stay tuned...
  5. D'ohh!! No sooner did you invoke the Kraken than it appeared to devour my mission in Moho's hood. It was a strange one too, that made my ship disappear in the orbital view instead of the staging view. When I went back to the tracking station, everything was gone. Unfortunately my quicksave was corrupted as well, and my last named save was ages before between Kerbin ejection burns. Sigh. Anyway, I mention it not because I'm aggrieved but because it happened just as I think I figured out how to cheaply zero in on Moho from an Apoapsis encounter, and I want to communicate that before this thread dies. So: Your Moho relative speed is much worse if you initially hit Moho's orbit at its high point, but there are also factors that work in your favor if you do it that way. One is that you can hit Moho's orbit there with very low inclination using just one Eve gravity assist, while it takes either lots of burn or two (very tedious) Eve assists to get you all the way down to Moho's Pe for your initial encounter. IIRC, Metaphor spent 1300+ dV to get to that first Moho encounter, while I'm doing it for about 1150. From there, you need to bleed off a lot less total dV to get captured from a Pe encounter than from an Ap one, but as I think I've figured out, the penalty for using gravity assists to do that is quite significantly less starting from an Ap-tangent orbit than from a Pe-tangent one. The key issue is that every time you use a Moho gravity assist to lower your Ap, you will lower your Pe some amount as well. If the planets are moving counterclockwise, swinging around Moho to lower your Ap moves your Pe a little bit in and a little bit clockwise each time. If you start from an orbit that is tangent to Moho's lowest point, this Pe lowering is a pure penalty, because both the inward and clockwise movement of your Pe put it further inside Moho's orbit. If OTOH you start from an orbit that's tangent to Moho's Ap, this lowering and pivoting of your new Pe follows the lowering of Moho's orbit as it goes toward its Pe, significantly reducing how far below Moho's orbit each successive grav assist pushes you. Moreover, if you do just a small prograde burn at around 15 degrees before your solar Ap, you can push your Pe back out and clockwise even more for just a few m/s, also making your next encounter point earlier and closer to Moho's Pe. In this way, I believe that if you can both find a really good path between the resonant energy levels and optimally correct your Pe on each successive orbit, you can shimmy on down and around to a really cheap Moho capture. Anyway, that's my plan and I'm sticking to it...
  6. On the plus side, it appears that the editor interface works properly for me again. A while back the old one got all buggy for me, and I had to resort to pasting everything in from Word. On the minus side, all that text I pasted in before is now a complete garble of un-parsed tags. It's not like what I said was of any importance, but it's kind of embarrassing to be responsible for such a mess. I hope it's just because some things aren't fully implemented yet.
  7. [quote name='PLAD']... I never ran all the numbers to prove which way is better, but my tests seemed to suggest that the meet-Moho-at-periapsis gives you a lower speed at your first Moho encounter. I could be wrong. My criteria for judging the first Moho flyby is the speed you are going at the moment you first enter Moho's SOI, in Metaphor's winning run that was 1584m/s (orbital). The higher this number the more times you will have to flyby Moho, correct your solar orbit, flyby Moho... Since every correction costs dV, the fewer you have to do, the better. Even at 1584m/s Metaphor didn't brake into orbit until his 9th Moho encounter. And yah, timing is a bear when dealing with Moho. After my 2nd Eve flyby I had to circle the sun 5.5 times before getting the first Moho flyby because I just couldn't time the flyby accurately enough to get the Moho encounter right away. Here's a link to a picture showing the shape of my Eve-Moho orbit, so you can see where the Moho encounter is relative to its perihelion: [URL]http://i.imgur.com/SYZjn7g.png[/URL] For your comparison, I figure that Eve first crosses Moho's plane on Y1 D14.22 (roughly opposite Moho peri) and Y1 D46.55 (Roughly opposite Moho ap) and every 65.486 days after those (Earth time!). Let's see, in Kerbal time I think that is Y1 D53.9 and Y1 D183.2 and every 261.94 days after those.[/QUOTE] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]Thanks! That’s a lot of useful information, particularly the exact times of the Moho/Eve plane crossings. It’s pretty hard to nail those down just squinting at the orbital map. I’m basically doing all of this with manually placed maneuver nodes, using nothing more than eyeballing and node-twiddling. To calculate my corrections, I’m referring to a big Excel spreadsheet I made with all the return times up to 12 orbits out for 22 different Moho-resonant orbits between 5:2 and 12:11. As to the speed at first encounter, I’m definitely going quite a bit faster than 1500-odd m/s, so you’re right about that. It will be interesting to see if I can walk down through the many required encounters for less than Metaphor did. Based on my experience so far, a lot of the transitions from one resonant level to another could in theory be made for just a couple of m/s by dialing in each encounter perfectly. For the levels before 5:3, I was actually flying by Moho at around 30km, but to get to 5:3 I had to fly by at only 6km. Still, all my corrections to that level were about tuning the encounters and not about losing energy to get to the next level. That may change as I get closer in, but the resonant levels actually get denser as you get closer, while at the same time the amount of assist you get at each encounter increases. One other issue I will have to contend with though is the accumulated radial acceleration that puts my Pe further and further inside of Moho’s orbit with each successive encounter. I’m assuming that’s why Metaphor alternated sides going past Moho, but that also increases the number of encounters required to slow down. Starting at a place that is not exactly at Moho’s Pe can actually help you in this regard, as you can set it up so that your orbit processes as you lower your Pe, keeping it closer to Moho’s orbit. Anyway, we’ll see how it all works out for me. It’s really fun trying to do this, but it sure is time consuming….[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  8. [quote name='PLAD']I find your post most intriguing. As one of the entrants that Metaphor beat so soundly in[URL="http://forum.kerbalspaceprogram.com/threads/74375-Lowest-Delta-v-to-Moho"] that challenge[/URL], I've often thought about how to beat his score. I determined when Eve crosses Moho's orbital plane, my plan was to find a Kerbin departure that arrives at Eve at one of those times, and then use the double-flyby path and then Messenger-style braking to get to Moho cheaply. Unfortunately I found that if you arrive at Eve with the lowest possible energy from Kerbin, you do not have enough energy to get flung to Moho's orbit without more burning. And the windows are so tight that you can count on needing many orbits of the sun between the second Eve flyby and the first Moho flyby, so I can't use my applications to figure them out. I sometimes consider a new 'lowest-dv-to..' type challenge for all the planets, but we'd have to agreed on a standard start orbit at Kerbin and final orbit at the target (or go surface-to surface like the old challenge). In any case I'd love to see your solution for a low-dV trip to Moho, especially if it beats Metaphor's![/QUOTE] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]Alas, it is slow going. If I do ever manage to beat Metaphor, it will not be by much, but I think there may be a slightly cheaper path this way. I’ve posted some pics of the first part below. What I found was that if I ejected from Eve’s descending node with Eve at like -25 deg, for around 100m/s more than the minimal Hohman transfer (~1140 m/s), I could set up an encounter at or very near the Eve-Moho ascending node. This in one flyby allows me to do nearly all of the plane change and to drop to a perfectly Moho-tangent orbit that is very close to 2:1 resonant. My biggest problem right now is I’m arriving at the wrong time. There’s also still 0.5 deg of orbital tilt because I’m not ejecting from exactly the right spot. I’m hoping that if I move my Eve intercept to the correct position, it will still cost about the same and perhaps put me in a better phase relationship with Moho. We’ll see…[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000] [/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000][imgur]rLqgm[/imgur][/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  9. [quote name='cantab']If I remember rightly on my Moho trip I did a "pre-capture" burn a few hours before even entering Moho's SOI, to slow the ship down so I didn't go sailing on through.[/QUOTE] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT=Calibri][COLOR=#000000]Since Mojo’s gravity is so feeble compared to the high velocities down there, the Oberth effect really doesn’t do much for you. So once your orbit is tangent to Moho’s, you can basically burn retrograde at the point of tangency until you’re at a period that’s 3:2 relative to Moho’s plus half the time it will take Moho to next reach that same spot. That will quite substantially reduce your capture burn when you encounter Moho on the next go-round.[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  10. Make career mode about something beyond just unlocking the tech tree!
  11. [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]After working away at it for like 5 hours last night, I’m pretty sure I can just edge out Metaphor’s record of 1700dV from LKO-LMO (if I don’t run out of patience), but it really is quite a pain in the end that should not point towards space. The whole key will be finding a path around Eve that is close enough to the Moho ascending node to minimize subsequent plane correction, but still intersects Moho’s orbit in a way that generates an encounter with minimal additional dV. Right now, I’m hitting Moho’s orbit at almost exactly 2:1 but 90 degrees out of phase with it. That unfortunately puts me in a spot where I need to burn for a good 250m/s to get an encounter even 5-6 orbits later. Doing that last night, I was actually able to hop down the next four resonant orbits: 11:6, 9:5, 7:4, and 5:3 for under 80m/s total (!). Going up to 12 orbits, I’ve now plotted 13 more resonant energy levels I could hit on the way down to Moho insertion. I’m pretty sure that with enough patience, I can find a similarly cheap path through those that wlll leave me with a trivial insertion burn, albeit 15 years after leaving Kerbin. As my current save stands, in 5:3 resonance with 1580dV expended, I think I could make LMO for around 1900 total, which is pretty darn good, but to beat Metaphor I’ll need to nail that first Eve encounter…[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  12. [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]Burning up on re-entry has never been an issue for me in 1.0.5. I’ve never even come close, but then I basically do what Rune described. Burning up trying to make orbit is a much bigger issue for me, since I now have to fly at >1,200 m/s on the RAPIERs for a long time, pointed prograde, through upper air that is quite a bit thicker than it was in 1.0.4.[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  13. [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]Figuring out how to get to Moho cheaply has been a fascinating problem. I’m not done yet, but I’ll post an album here when I am. So far, it’s looking like I’ll manage capture at Moho about 3.2 km/s all told from LKO. I’m not sure how much more getting to LMO will cost from there, but I imagine only a few hundred m/s. I give a more detailed explanation, with instructions that less experienced Kerbal wranglers can hopefully follow, below:[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]STOP READING NOW IF YOU DON’T WANT SPOILERS. Even if you don’t end up doing the long, later, part, I think the initial approach will still save you several hundred m/s vs. ejecting straight to Moho from Kerbin, even if you do it at the nodal point as suggested upthread. [/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]What I found was that if you eject for Eve from near its descending node with Kerbin, with Eve at a tighter phase angle (like -25deg vs. the -57 for a standard Hohman transfer), for about 1150 m/s you can set up an encounter about 2/3 of the way around Eve’s orbit from where you eject, i.e. later than for a Hohman transfer. As it turns out, that spot is almost exactly at the ascending node between Eve and Moho, which you can easily identify by looking at the orbital map. You’ll want to launch from the KSC about halfway between sunrise and noon and shoot for an orbit that’s inclined about 22.5deg southwards from there. When you’re done, the highest latitude of that orbit should be near the sunrise terminator. When you eject retrograde from that orbit at Eve’s descending node, you end up pretty close to its orbital plane. It doesn’t have to be perfect, so long as you can place your ascending node close to the intersect with small subsequent corrections. Anyway, from that Eve encounter I was able to eject to an orbit that goes just outside of Eve’s and intersects Moho’s on the opposite side, with a tilt of only about 0.5deg relative to Moho’s. From solar Ap a few days after Eve ejection, the remaining dV to complete the plane correction for me was only around 80m/s, but maybe a better navigator could work it out to eject dead-on into Moho’s orbital plane.[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]So with that maneuver you’ve already shaved off a lot of dV from the more conventional way, getting to a significantly lower orbit than direct Kerbin-Moho transfer for 500m/s less dV, and furthermore getting 6.5deg of the 7deg plane correction for free, but then it gets even more interesting. With a series of carefully calculated burns, it’s then possible to set up a succession of Moho encounters to gradually walk down a ladder of ever-lower resonant orbits. [/COLOR][/FONT] [COLOR=#000000][FONT=Times New Roman][SIZE=3] [/SIZE][/FONT][FONT="Arial"]Since the encounter indicators at Moho are all squirrely, this required some calculation. To get my first Moho encounter, I advanced the clock from my plane change correction to the next time Moho was at the intersect point. From there, you know Moho will return to that spot at t+102.6d, 205.2d, 307.8d, etc. You then place a node right at the intersect. If you add the time to this node to the period of your initial Moho-tangent orbit, you’ll generate a similar series of return times to that spot for your ship. You then just need to do a little bit of math to figure out how much you need to change (lower if at all possible) your orbital period to make one of your return times line up with one of Moho’s. This itself will not be a resonant orbit, because your initial approach changes the calculation, but from there out you will be shooting for them. In my case, I came in on an orbit that was a little lower than 2:1 resonant with Moho’s, and I had to lower my orbital period about 12 days to get a re-encounter 3 orbits later. I then basically tugged retrograde on that maneuver node until clicking on the orbital path behind my ship indicated the right period, resultimg in a ~200m/s burn. I then advanced my ship the first 2 orbits and did an additional ~25m/s correction to set up the actual encounter using the indicators. From there, you set up your encounter to get as close to Moho’s surface as possible from the outside. For me this lowered my initial orbit almost exactly to a 5:3 resonant one, requiring me to boost only a small amount retrograde to get another encounter 3 orbits later. This in turn lowered me to somewhere above a 3:2 orbit, with yet another relatively small retrograde correction to set up the next slowing encounter. And so on down the energy shells: 5:3, 3:2, 3:4, 4:5, and finally 9:8. Lather, rinse repeat. I got too tired to continue when I reached the final 9:8 orbit last night, but I expect from the ~2000m/s speed I had at the Pe of my previous (5:4) encounter that I’ll only need to burn for maybe 600 m/s to get captured and 200-300 more to get to a low orbit. When I finally do, I’ll post the results in an album. Working this out has been just the most excellent tutorial in orbital mechanics for me, and I’m sure I can do quite a bit better than this if I work everything out just right. [/FONT][/COLOR]

  15. [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][COLOR=windowtext][FONT=Arial][FONT=Arial][SIZE=3]Well you know 1.1 with the physics port is going to change everything several more times (I’m guessing like 3 times – once when they initially release it and then maybe two more times after that as they try to rebalance it to quiet all the screams of outrage), but then I really do hope they do try to leave the basic physics the same as much as they can. If like me you are focused on probing the limits of what can be done, having those change significantly before you can really get a handle on the problem over and over and over again is starting to wear a little thin.[/SIZE][/FONT][/FONT][/COLOR] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  16. I don't get why somebody felt they had to troll rate this thread. This is a perfectly legitimate subject for discussion here.
  17. This would definitely be a big improvement. The only things I can think to add would be 1) to have 3 explicit coarse/fine settings, where one mouse wheel click equals 0.1, 1, or 10m/s, which are shown somewhere on the display and can be changed with hotkeys like timewarp, and 2) to have some description of where the node being edited is (e.g. "orbiting Kerbin") as part of the display, so that you don't get confused about what's what.
  18. [quote name='eataTREE']I have been to Moho. I did take a lot of radiators, but this was to dissipate the heat from my nuclear thermal rocket rather than because of conditions at Moho. (I don't recall having to deploy the radiators at Moho, except during a burn.) My biggest problem with Moho is that a) as you point out, it takes a ridiculous amount of d-V to get there, and b) when you get there, it's freaking boring. Airless, monochromatic, and a landscape like Dres, only not as feature-rich or interesting. Once things get more stable again (right now I'm having bad, bad problems with crash-to-desktop on scene change) I might load some mod like Interstellar and build a solar-powered microwave transmitter station/antimatter bottling plant in Moho orbit. Other than the intense plentiful solar energy, or to cross it off The List, I can't think of too many other reasons to go there.[/QUOTE] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]You know how they say getting there is half the fun?

  19. [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][FONT="Arial"][COLOR=#000000]The thing about the old aero that made it easier is that you could fly a dinner plate into orbit face-up if you strapped enough boosters to it. Now you actually have to think about how the thing will fly. My new Moho rocket has a great big bulging fairing at the top covering the upside down lander, and I still haven’t figured out how to make it not want to flip over when it hits the sound barrier.[/COLOR][/FONT] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  20. [quote name='Geschosskopf']In 1.04 my Moho lander was left behind as a base for future expeditions and the crew returned to the mothership on little open-seat scooters like this: [URL]https://farm1.staticflickr.com/536/19096688710_4db8c3dc49_b.jpg[/URL] Notice that the Kerbal has a heat gauge on his tummy and his expression indicates he's not having a good time. Also, I launched in the local afternoon so when I tipped it over to the east to head for orbit, the solar panels were pointed away from the sun, which caused problems with running low on electrical charge so I had to reach orbit by a stair-step trajectory. But it did work. Yay Lifesaver tanks ;).[/QUOTE] LOL that's priceless!

  23. [quote name='Laie']Hint: forget about the transfer window planner. With inclination changes and everything, nailing the transfer is quite hard while most transfer windows aren't really worthwhile. The easier way to do it: a) look at the map sideways, depart from Kerbin when Kerbin is at it's AN/DN with Moho. b) do a transfer burn so that you will just touch Moho's trajectory c) once you get to that point, do a retro burn so that you meet Moho in this place on your next orbit It's not the most dV-effcient method, but it's not especially wasteful either. About 4500m/s from LKO, IIRC. The upside is that this approch is quite plan-able, with "transfer windows" come up twice a year (at every AN/DN), and no nasty surprises at your capture burn.[/QUOTE] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT][COLOR=windowtext][FONT=Arial][FONT=Arial][SIZE=3] FWIW, my plan is to try to set it up so that I encounter Eve at the node and can then do the plane change via gravity assist.[/SIZE][/FONT][/FONT][/COLOR] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT]
  24. [quote name='GeneCash']What? you can't go to Moho with only 7,217 m/s delta-v using 2 Eve flybys and 8 Moho flybys over 10 years like this guy?

I’m sure you can drop your orbit quite a bit swinging around Eve as well as do a lot of the plane change if you time it right. A subsequent Moho flyby can then probably get you to a 2:1 resonant Moho orbit which can then be relatively cheaply adjusted to re-encounter a low orbital angle. Sounds to me like something fun to try tonight![/SIZE][/FONT][/FONT][/COLOR] [FONT=Times New Roman][SIZE=3][COLOR=#000000] [/COLOR][/SIZE][/FONT] :)
  25. [FONT=Arial][COLOR=#000000]Ahh, Moho! I did my first mission there in like 0.20. The inevitable rescue mission after my seemingly generous seat-of-the-pants dV allowance came up well short was the first time I ever had to rendezvous two vessels in interplanetary space. Good times! As to it being the hardest spot in the game to reach, I think that depends on how good you are at flying. The surface of Tylo and back may require somewhat less dV, but that landing is a bear![/COLOR][/FONT] [COLOR=windowtext][FONT=Arial][FONT=Arial][SIZE=3] [/SIZE][/FONT][/FONT][/COLOR]
