⟨Dost Thou Even Shred⟩ So Im trying for lunar flyby and Im using a mix of SRBs and Liquid fuel for TLI how can I get it more accurate
<paculino>
You can use bettertimewarp to use something like 10 % physics warp to cut off liquid more accurately, and you should use rcs for minor corrections
<kitty1>
Have you tried writing a script for the craft to make it automatically shut off at the correct time? Its been a long time but I think thats what I would do?
<queqiao->
⟨Quadrupole⟩ Latest MJ dll does that
<paculino>
Oh yeah, it takes the spool-up into account now by being based off of delta-V, not time
<queqiao->
⟨Dost Thou Even Shred⟩ Well the thing is that it doesnt come close to the predicted orbit at any point
<queqiao->
⟨Dost Thou Even Shred⟩ Cause I tried better time warp
<paculino>
It sounds like you are starting it at the wrong time, or pointing in the wrong direction
<queqiao->
⟨Dost Thou Even Shred⟩ And how can you use mechjeb for principia
<queqiao->
⟨Dost Thou Even Shred⟩ ⟪paculino⟫ It sounds like you are starting it at […] ⮪ its the right direction but I might try with time
<queqiao->
⟨Dost Thou Even Shred⟩ Also using rcs isnt possible since I have no control with a science probe
<paculino>
You should still have forward/backwards rcs translation iirc
<queqiao->
⟨Dost Thou Even Shred⟩ No RCS only works with near earth or deep space
<queqiao->
⟨Dost Thou Even Shred⟩ and neither are options as of now
<queqiao->
⟨Quadrupole⟩ Then you should not do an unguided moon shot at all. Try having at least a zero-controllable mass NE core
<queqiao->
⟨Dost Thou Even Shred⟩ But keeping power for 5+ days is not that easy
<paculino>
If you have neither a launcher able to send enough batteries and/or a better probe core, nor the solar panel capabilities to keep it charged for five days, you probably shouldn't be trying yet. Doing so would be a caveman method
<queqiao->
⟨Dost Thou Even Shred⟩ Unguided is really the only way to do it with 1958 tech
<queqiao->
⟨zephyr⟩ Isn't that the node with the rd0105?
<queqiao->
⟨Dost Thou Even Shred⟩ Would that really be caveman though seeing I dont think most moon flybys were not guided
<queqiao->
⟨Dost Thou Even Shred⟩ Yeah but Im currently reasearching it
<queqiao->
⟨zephyr⟩ Ok but it will happily do guided tli for you
<queqiao->
⟨zephyr⟩ Even off 60t
<paculino>
Keep in mind that most unguided lunar missions failed
<queqiao->
⟨Dost Thou Even Shred⟩ Ok I guess Ill try to do guided just solar panels are too bulky so hopefully I can hold the batteries
<paculino>
How soon can you get the next level solar panels?
<queqiao->
⟨Soviet Onion⟩ ⟪paculino⟫ If you have neither a launcher able to […] ⮪ no way ! even paculino became a bot 😔
<queqiao->
how many more will fall to the bot-world and become minions to the bots now ?
<paculino>
Some say being digitized may grant near-immortality
<queqiao->
⟨Dost Thou Even Shred⟩ ⟪paculino⟫ How soon can you get the next level […] ⮪ Im a bit a ways away
<queqiao->
⟨Dost Thou Even Shred⟩ Im low on science thats why Im heading to the moon
<paculino>
I would have two fly-bys in the build que if I were you, both as a backup, and for quickly sending a second one to get more science
<paculino>
If you can use forward/backwards translation rcs, you can sometimes fine-tune the fly-by to repeat after a few months, but that requires better solar panels than you have now.....
<queqiao->
⟨zephyr⟩ They nerfed fore/aft rcs to a later avionics, it's why i had to switch to fully guided tli
<queqiao->
⟨Dost Thou Even Shred⟩ Well Im just launching a NavSat to pass time till I get the proper engines
<paculino>
I must be a version or two behind
<queqiao->
⟨NathanKell (he/him)⟩ ⟪Dost Thou Even Shred⟫ Would that really be caveman though […] ⮪ The Luna flyby/impactors had midcourse corrections. Pioneer 0/1/2 failed, but had they succeeded did have velocity trim motors. Pioneer 3 failed, but Pioneer 4 (unguided solids for TLI) only got within 60,000km (!) of the moon.
<queqiao->
⟨NathanKell (he/him)⟩ * their LVs succeeded did have velocity trim motors to correct for unguided TLI.
<queqiao->
⟨NathanKell (he/him)⟩ Also lamont very kindly merged my Principia PR, so you can just use regular MJ dev now
<queqiao->
⟨Kerbinator⟩ ⟪NathanKell (he/him)⟫ Also lamont very kindly merged my […] ⮪ huh? Means that the entire MJ can read principia correctly?
<queqiao->
⟨Stonesmile⟩ The MJ principia node executor now uses the initial dV provided by the node and burns that much dV, instead of what it did previously which was burn until the endtime of the node
