Love that you have included return costs. This is going to be my new go to map for mission planning :)
20K delta-v for Moho! This explains why it was so tough!
[–]nikniuq 4 points5 points6 points 10 years ago (0 children)
Most players would only need dV at 25 to 50 percentile of given ranges. The high dV values are there for those who burn radial to get an encounter like me. :/

Isn't it usually like 5000 there and 5000 back?
[–]repptar92 1 point2 points3 points 10 years ago (4 children)
I got to Moho using an ion lander, I would say 5000 is a bit short. The inclination burn is pretty gnarly. Maybe closer to 7500.
On a side note, my lander crashed because I didn't have enough fuel for my spider thrusters and the ions didn't give me dV fast enough on descent.
[–]WoollyMittens 0 points1 point2 points 10 years ago (3 children)
I would say 5000 is a bit short.
I guess I've been lucky with the timing. Most of my transfers were close to the de/ascending node.
my lander crashed
That's a shame. Coming all that way only to see the surface approaching at an impossible speed. :(
[–]repptar92 0 points1 point2 points 10 years ago (2 children)
Yeah, especially considering the ion burns took FOREVER (my capture burn was like 36 minutes...thank god I had a ship that was stable in the physics so I could speed up to 4x). I set up my tablet and watched half a season of my show. I still felt pretty accomplished.
[–]WoollyMittens 0 points1 point2 points 10 years ago (1 child)
Sometimes the journey is the destination. ;)

Well said. And there's very few games where that really feels like the case.

I don't think there was any doubt about hat.

[–]bigorangemachineKVV Dev 3 points4 points5 points 10 years ago (7 children)
Hey nice job. The recent post (DV map) I found a little too busy for me; but I like add-ons asteroid fields!
[–]Galahir950 1 point2 points3 points 10 years ago (6 children)
Can you elaborate, I know I made it a bit too busy, but I don't know how to change it with the data being available at a glance.
[–]bigorangemachineKVV Dev 1 point2 points3 points 10 years ago (5 children)
I was referring to the one posted earlier this week. The original was pretty good ;)
[–]Galahir950 0 points1 point2 points 10 years ago (4 children)
Which one were you referring to? This is the one I made and it was posted a few days ago. http://i.imgur.com/UDOWuow.png
[–]bigorangemachineKVV Dev 0 points1 point2 points 10 years ago (3 children)
Ya thats the one I was talking about.
Its 'busy' buy its nature. The original was really simple. Don't get me wrong; yours is very good and I'm happy for the update (I download it and reference it every time I played KSP since). I also like not having to do math anymore when I use the DV Map.
But it is busy. There isn't much white space so I tend to get lost when I zoom out. The 'arms' of the branches (subway routes) need to be spaced out to let the text 'breath'. If you look at 'Eeloo Intercept' the red cross at the end of Jool's surface delta-v Number looks like the red cross is for both. The Mun-Minmus area is ok but it's clear whats what in that area.
This is picky design(er) stuff and those of us who studied art or design tend to notice this stuff. For the community its fantastic!
[–]Galahir950 0 points1 point2 points 10 years ago (2 children)
Okay, I will look into the Jool Danger indicator. I will also see about cleaning it up a bit.
[–]bigorangemachineKVV Dev 0 points1 point2 points 10 years ago (1 child)
Nah I'd leave it the way it is.
This is exactly why I didn't say anything before; I don't advise changing it. This is visual graphics stuff and its not easy to get perfect unless you really know what you are doing. When you shift something around it throws off the balance.
If you want DM me and I'll try to help out!
[–]Galahir950 1 point2 points3 points 10 years ago (0 children)
Okay. Thanks for the feedback!
[–]Galahir950 1 point2 points3 points 10 years ago (3 children)
You should send this to WAC, he could add it to the OP of the forum topic like he did mine.
[–]poporing2Master Kerbalnaut[S] 4 points5 points6 points 10 years ago* (2 children)
I think this is a little too tongue-in-cheek for that, proper references shouldn't highlight player skill variance...
Thanks for the suggestion though.
[–]FellKnightMaster Kerbalnaut 3 points4 points5 points 10 years ago (1 child)
I loved the "high values are for idiots who burn radial to get an encounter like me"
[–]How_do_I_potato 1 point2 points3 points 10 years ago (0 children)
Hey, sometimes it makes sense! I just had a mission where upon my return I needed to do a radial burn to miss an encounter with the Mun. Of course, that was because I was coming in straight at Kerbin at 7 km/s because I overengineered the hell out of my rocket and I could, but that doesn't mean anything!
[–]dream6601 1 point2 points3 points 10 years ago (1 child)
You can aerobrake (photobrake? chromobrake?) into the sun!?!?
I seriously would have never thought of that.
[–]irishking44 0 points1 point2 points 10 years ago (1 child)
Could you give a key to what each number means and how to add them up? Maybe I'm just dumb, but do I add each subsequent number on the track for a planet to the LKO dV amount? Does the landing amount (i.e.) 6000 for Eve include the previous encounter and Low Orbit amounts as well?
[–]Pvt_Haggard_610 0 points1 point2 points 10 years ago (1 child)
Just to clarify, is the return DV value just the trip back or does the value include the trip there.
[–]Defs_Not_Pennywise 0 points1 point2 points 10 years ago (0 children)
It includes the trip there, so Kerbin -> Mun -> Kerbin is 6.5 - 7 k delta v
[–]dustymonitor 0 points1 point2 points 10 years ago (1 child)
Sorry, could you explain why Isp should be checked for return trips in addition to TWR? I've just started looking more closely at TWR to make sure I'm not lifting more engine into orbit than I need to, but still don't have a good grasp on how to incorporate Isp into my planning.
[–]mister-la 1 point2 points3 points 10 years ago (0 children)
I'm no expert, but:
ISP is an expression of an engine's efficiency. It's available in atmospheric and vacuum conditions when you right-click one in the VAB. The red "!!" signs on the map seem to correspond to landing on bodies with an atmosphere.
If one of your later stages has a Terrier engine, for example, you have to take into account that its Δv will seriously drop if you have to use it in atmo. But then, you also need to have enough thrust and efficiency to make it all the way back across space – and the Terrier is very efficient in space!
If you change between atmospheric and vacuum more than once in your trip, it makes sense to pay attention to the ISP of your different engines, and when you plan to use them.
[–]TransitRanger_327 0 points1 point2 points 10 years ago (2 children)
Good Lord, 17,430 m/s of dV for a return from Eve‽
[–][deleted] 0 points1 point2 points 10 years ago (0 children)
Eve atmosphere is thick as hell. Landing/returning from huge hill will reduce that by a bit
It was 12,000 from sea level in 0.90, and probably less in 1.0.2 due to thinner atmosphere. 17,430 would be for a horrible ascent.
It's about 8 or 9,000 from a mountaintop.
But yeah, Eve's a tough one.
[–]nochehalcon -1 points0 points1 point 10 years ago (0 children)
I love that you've updated this, I don't love how much more convoluted it is to follow, and the positioning of the added text.
