So the most efficient is the maximum thrust the vehicle can handle without breaking. Beyond that point you can make it to orbit (with a sufficient mass fraction), but now we are back to the previous example where low thrust essentially mirrors the "infinite number of increments" to orbit. Anything below the amount to counter acceleration due to gravity is lost, so we can ignore those. #KERBAL SPACE PROGRAM CONTROLS CHEAT SHEET FREE#Picture a scenario on celestial body with no atmosphere where we are free to adjust our thrust from zero to infinity (given a fixed specific impulse). Examining a portion of the raising burns, we find that the efficiency of each later burn is worse than the earlier burn. Picture an extreme scenario, where you raise your orbit gradually, over an infinite number of increments, until it is precisely the same orbit at the Mün. I am not intimately familiar with the existing standardized terminology here, so I'll probably cock up my explanation, but in simple terms: You are correct that the Oberth effect is involved. There may be an old Scott Manley video on it. I would assume burning directly for the moon without stopping to orbit would be significantly more expensive than circularizing first then injecting There is an optimal altitude within the atmosphere for direct injection, dependant on target body and vehicle characteristics.ĭo you have a link to a more in depth explanation that's also comprehensible to someone with math brain but not formal math training? I was in the 'it shouldn't matter' camp, but I also figured there was some weird physics property probably related to the Oberth effect that invalidates my hypothesis. Atmosphere gets in the way, though, so being on an injection trajectory below a certain altitude is more expensive due to atmospheric drag losses. Circularizing at any altitude and doing an injection burn is necessarily more expensive than injecting at a lower altitude. Locked camera mode is your friend on your first landing (and every one after). That's how you play campaign mode! Good luck with your landing In order to afford to afford this mission I had to funnel funding from another contract into this one, so either this mission is a success or my program is bust I made it to a 14km circular orbit around the Mun and I'm just hoping I have enough delta-v to land and takeoff. I should have done the "Translunar injection" before I did the "Transposition and docking" because I think I wasted a lot of fuel circularizing around Kerbin when I should have just burned straight for it. Takeoff was a nightmare because the hidden lander module happened to be a massive pivot point for the whole ship and somehow I flapped myself into orbit like a rocket powered seagull. Which is to have a comfortable foundation of tech, funds, and leveled kerbals to start *really* engaging with Remote Tech, and some of the more challenging tourism contracts, and looking to Duna (which I've only landed on once ever) and beyond.įirst attempt at building an Apollo-style mission. Just got to haul my Kerbals around Mun and Minmus to get them back to their previous levels, and I'll mostly be back where I was. #KERBAL SPACE PROGRAM CONTROLS CHEAT SHEET INSTALL#For now I've got my install locked to the 1.10.1 'beta'. Thanks for the heads-up on the automatic save backups thing *definitely* will keep that in mind for the future. I load the game through CKAN anyway - much easier and I don't need to have Steam running to play. You lose access to the Steam Workshop which I can live without, especially since I'll never accidentally lose a savefile to an inadvertent update. #KERBAL SPACE PROGRAM CONTROLS CHEAT SHEET MOD#I usually copy the entire KSP folder to another disk and run it from there instead of through Steam whenever I want to maintain a certain version with mod support. Under game properties you can roll-back KSP to any version you want, but it's still a pain. #KERBAL SPACE PROGRAM CONTROLS CHEAT SHEET UPDATE#Steam got rid of the "don't update this game automatically" setting which really sucks. Then rename it "persistent.sfs" and load - you should be back in action. Find the one you think is from before the accidential update, and copy it to the previous directory. Look in the "saves" folder, find your save folder, and check the "backup" subfolder. If you're ever at this juncture again, remember there are backups you can load. ![]()
