Without a stock launch window tool in KSP2 for now, I'm back to using AlexMoon Launch Window Tool: https://alexmoon.github.io/ksp/ This gives me the launch window time, though you need to add +1 to the year for earliest departure, as KSP2 is 1 year offset (KSP1 year 1 = KSP2 year 0). I run the Python script below (run locally or at https://www.online-python.com/), input the launch time, and current time, and get the difference in number of seconds, and copy that. Once I have that, I create a maneuver node, and using Maneuver Node Controller (https://spacedock.info/mod/3270/Maneuver Node Controller), put in the seconds to skip ahead, along with the usual delta-V amount. #calculates time in seconds to add for transfer window #input is transfer window time and current time #1 year = 426.08 days = 2556.50 hours = 9203400 seconds #take first number of 92303400 #add 1 year to KSP2 time, as KSP1 year 1 = KSP2 year 0 #Launch window calculator using KSP1 date convention: https://alexmoon.github.io/ksp/ def convert_to_seconds(year,day,hour, minute, second): sec_year = year * 9203400 sec_day = day * 60 * 60 * 6 sec_hour = hour * 60 * 60 sec_minute = minute * 60 return sec_year + sec_day + sec_hour + sec_minute + second def get_time(): year = int(input('Year: ')) day = int(input('Day: ')) hour = int(input('Hour: ')) minute = int(input('Minute: ')) second = int(input('Second: ')) return convert_to_seconds(year,day,hour,minute,second) #main program print('Input Launch Window time') launch_time = get_time() print('Input Current time with KSP1 time convention (+1 year if KSP2)') current_time = get_time() print('Seconds until launch') print(launch_time - current_time)

Hey guys. I'm trying to plan a mission to Duna. Launch would be around day 26. Alex Moon's calculator states ejection angle 24 to prograde, delta V of 2002 m/s at phase angle of 124.11degrees. Yet when i set up a node with those parameters, I don't even get a close approach. Any advice is welcome.

So since I've started playing I've somehow never launched a proper mission to other planets (other than the odd probe). I got back into KSP a while ago thanks to adding a pile of mods that add the depth I was after (mainly everything and anything USI and Near Future) and I've now decided that a massive mission to Duna sounds like a plan to step up from my multiple 20 kerbal colonies on the Mun and Minmus. Currently I'm figuring something along the idea of a Martian style mission - probe dropped supplies ahead of the mission with a minimum duration on the surface of 30 days (just cause). Basically this all boils to a rather simple question - assuming the stock solar system - roughly how long sounds like a good budget for life support supplies / habitation? I reckon I need to allow at least 300 days for the transfer there plus surface mission time (30 days) but when is the best launch window for return? Is this going to be the expeditionary mission I'm planning on or should Jeb and co be planning for a year or more sat there?

I can't find any information on how to get from the surface of Minmus to Eeloo. Are direct transfers not possible? Do I really have to jump back down into Kerbin orbit? The launch window planner calculators won't calculate a transfer between Minmus and Eeloo, and I'm kind of clueless. Do I just need to do trial and error? I can't imagine I'm the only person in the history of this game to want to try flying to Eeloo from the surface of Minmus—yet I haven't found anybody asking about it here or on Reddit or in Google searches...

a little window or HUD (like KER) that shows the next launch window to planets or moons (a customizable list to only show Mars, Saturn, Titan...), so i don't miss my contracts deadline
