Don't worry I just got a 2290ms maneuver dont know how I was getting 3900ms soz for wasting your time lads.

Let me clarify, I am not new to the game I know the phase angles I have the encounter in the maneuver node however the maneuver says it takes over twice than what it is supposed to be. I am following the correct method of transferring following the ksp interplanetary calculator. I am doing everything by the book, does anyone think that 1915 in delta v is a little optimistic, prove me wrong?

Right, I am planning a manned mission to Jool for the first time and its says that the delta V needed to get to Jool on the KSP wiki is around 1900ms from a 100km Kerbin orbit. Now when I do the optimum Hohmann transfer it predicts on the maneuver node that the Delta V required is around 3900ms. Now I use the correct phase angles and everything is how it should be but I do not get the 1900ms delta v that I should. CAN ANYONE HELP?

I have sent probes and established satellites in the Joolian system, I've been to Moho, I have sent manned missions to Gilly and Duna and sent unmanned probes to Eve but I believe nothing matches the varied high albedo mountain ranges and Ice flats of Minmus. What do you guys think?

Duna: Low Gravity: Muscle and bone density lowers over time. Temperature: Too low Freeze to death. Atmosphere: Thin atmospheric pressure would be also low serious effects on exposed bodies. H2O: present however in its solid frozen form, unseasonable energy requirements to melt through heating methods.However if possible water may provide a suitable atmosphere if plant life could be introduced and photosynthesis could occur. Magnetic Field: If the analogue for Mars is the same, the magnetic field does not exist and would slowly slowly tear the atmosphere away. Duna's biggest problems are the lower gravity and magnetic field which would be the hardest if not impossible to influence making Duna unsuitable for terraforming. Eve: Eve also does not have a magnetic field if it is correct to its real life partner Venus. Eve has suitable ASL gravity. However the Atmospheric pressure is higher than of Kerbin and poses problems to exposed life forms. However the possibility of photosynthesis and chemosynthesis by extremophiles could slowly convert the CO2 and sulphur rich atmosphere into a Kerbal friendly environment provide Water was freely available for use in photosynthesis. The temperature however would still be far higher than that of a Kerbin so would limit the introduction of life onto eve. Neither Planets would be very suitable for terra-forming however if I had the chance to choose to visit either of the planets it would be Duna.

Don't set your sights on anything like a Mun landing until orbital mechanics are really solid. I feel the main problem with beginners is that many newbies think a Mun landing will be easy straight away. Really nail understanding asparagus staging usage within the atmosphere and node values of target positions. Once I understood these two fundamentals I could really nail Mun landings and going further right to worlds such as Laythe. Eventually a user could consider using equations and Delta V maps to plan manned missions to interplanetary worlds. This is far easier than "winging it" or attempting missions by the trial and error method.
