[Request] Delta-V maps

[bsalis]

Well, the Kerbol system has grown. With the time and distances involved, a little more planning and little less trial-and-error is in order. I also have some plans in the coming months for some elaborate missions. So that leads me to ask...

Are there any diligent souls out there willing to put together, and share, a Delta-V map for the Kerbol system?

So that's not just getting to and from the planets, but also to the moons of the planets and back to low host orbit. Oh, and getting into orbit from the ground as well.

user JellyCubes on Reddit posted a great image of the new Delta V's for the planets. The delta V's once you're in the systems won't be very much (unless you're in low Juul orbit or similar). It's a beautiful chart:

I'm just having a great motion of gratitude towards JellyCubes for creating this, and towards you for sharing it, thanks!

Also, I might consider finally signing up on Reddit, of it has other jewels like this one...

Wow! Kudos to Jelly for the mao and Hillstache for posting it! Much appreciated.

Cheers!

[MrBailey]

Sorry. Double post...but twice the kudos!

Does it take into account excentricity and inclination?

That's a very helpful map for designing spacecraft. Are there any estimates how much delta-v it takes to take off from the new planets and moons?

Okay, KSP 0.17 has been out for a while now, so I thought it might be a good idea to bring this topic back up: could any of you folks who already landed crewed missions in the Kerbol System give us estimates on the ∆v required to go from the planets' and moons' surface back to low orbit? That would be incredibly useful for designing my first crewed landing! (only done orbital crewed missions so far)

Laythe surface to low orbit has taken about 3.2-3.7 km/s deltaV for me.

[Tommygun]

Oh, thanks for posting that chart.

[Enture]

Laythe surface to low orbit has taken about 3.2-3.7 km/s deltaV for me.

Thanks for that first answer!

Anyone else? ∆v estimates for Duna and Eve, at least?

[Vanamonde]

How does one convert that kind of delta-V rating to the kind we've been using, such as 4700 for Kerbin orbit? (Sorry, I don't know the proper terms to ask the question more clearly.)

[Enture]

Simple: 3.2 km/s ∆v = 3200 m/s ∆v

The "4700" you refer to for Kerbin is given in m/s. So 4700 m/s or 4.7 km/s, since 1km=1000m

Just did a MechJeb Ascent from Duna. Delta-V was 1460 m/s... so lets just make that a nice safe and round 1.5 km/s.

Eve is ... well Eve.

Thanks for the Duna data!

And yep for Eve, nhnifong's latest attempt at an Evian liftoff in the Picures thread says enough...

[Vanamonde]

Simple: 3.2 km/s ∆v = 3200 m/s ∆v

Cool. I've been using the equations from the Kosmo-not/Ancient Astronaught guide, but without knowing what the units were. My education proceeds apace!

Lovely chart. Would make a wonderful mousepad design. Too bad haven't needed mousepads for a while. Either way, thanks for posting.

There is also an app called KSP Calculator wich does it automaticly inclusive landing and return. Currently it is outdated because of KSP 1.0 (delta v to LKO is now 3500 instead of 4500) but the required delta V used for travelling is still pretty accurate.
