Manuver to duna?

[Guest]

Can you possibly get a Manuver all the way to duna ?

While it would be extremely difficult to perform, I am sure it is quite possible. Also, unless you got the perfect transfer location, the delta V required to do a single LKO to Duna burn would probably be considerably larger. If I am wrong someone please feel free to correct me.

Sure, I do it all the time.

It's super easy. About 95% of my burns go straight from LKO to Duna. The other 5% is when the game messes up with the altitudes and what not while switching sphere of influences.

Yes. That's the most efficient way to do it.

If you launch from Kerbin into LKO and then to Duna during or near an optimal transfer window then performing the transfer that way is the more efficient method.

If you're not launching at an optimal time then it's best to escape Kerbin's SoI and then orbit around Kerbol until it's efficient to transfer.

In other words, yes.

On around day 115ish Duna and Kerbin are in the right position for a direct burn... I managed to plot one by hand and I think it was around 7500 dV. Maybe a bit more.

I was actually going to do a burn for Duna in that time-frame but I didn't have all the ships in position that I wanted to make the voyage (it's gonna be a large multi-ship endeavor with kethane mining ships and orbital station if I ever pull it off)

I forget what the transit time was, 30 days-ish?

Another consideration though is the actual orbital insertion/capture. You're either doing an aero-capture or series of braking maneuvers or you need enough propellent for a direct insertion. (that was another reason I didn't make the attempt; I'm using the Real Fuels mod and the best I can do with my current designs are 9,000-10,000 nuclear, using drop tanks, which didn't leave a lot for deceleration.)

Edit: Wait, maybe I don't understand the question correctly... I was thinking you were asking about a high-energy transfer as opposed to a standard Hohmann's transfer. Either way, they're both possible from LKO
