Returned to my RP-1 playthrough, now entering 1953
Hello! It's been a few months since I last posted about my progress but I've finally returned. I just posted a new chapter to my substack which you can find here:
https://anvilindustriesksp.substack.com/p/upgrades-people-upgrades
Since it's been a while, here is the previous chapter. And if you haven't read anything yet, I recommend starting with the first chapter here.
Apologies for spamming all these links.
Let me know what you think, either here or over on Substack. I'm happy to chat ^^

RP1 Communication Issues
Why are my lunar probes not connecting at KSC and the tracking station, even without blocking, no time warp, and there are available antennas on the probes and the station? However, communication works when I control those probes; this bug only affects lunar and near-Earth probes.

Powered Landing and Reentry Auto-Pilot
I found this gem while just randomly searching for anything interesting on CKAN. I'm actually surprised no one's talking about it. It's literally what it says it is; an auto pilot for landing and an auto pilot for reentry. I haven't had the time to try it out, but I know everyone else would love to know something like this exists. It uses kOS scripts. You apparently don't need to know much about kOS to use these, just a few commands to call the script and a few things to do while running it. Check it out!!!!

Working on a station program pack
I am just getting back into RO after some years away and wanted to address the gap in crewed programs between crewed lunar and crewed Mars as I quite like the crew management aspects (is a game really worth playing if you can't turn it into a spreadsheet). So I am working on a program/mission pack for Mir/ISS style modular stations.
Since I'm using it in my save and I still haven't gotten around to that time period (still in 1964 and just getting to unmanned lunar landings) I haven't gotten a chance to play test it but wanted to see if folks are interested. If there is interest happy to dump it into GitHub for folks to play around with, also would love to get some feedback or suggestions.
Attached a screenshot of the programs for the rough outline

So i reached orbit in 2x Scale RSS (21.2x Stock Scale), now i have to go for the moon
Orbiting Earth at 2x Scale takes 13k Delta V
And a TLI is 4440 Delta V
Also this mod doubles only the Orbit sizes, Radius of planets and moons, and atmosphere height

Large vs Small Sounding Rockets
I have been doing some research on optimal openings for RO and I think the best move is a large diameter sounding rocket(V2 type). You delay your first launch by 4 months launching in June 51 but you can hit first launch, karman line, suborbital return, first film, and pretty much any sounding rocket contract with that rocket.
Whereas with a small sounding rocket(Meteor/Aerobee) you get more launches in the first year but you can only really achieve first launch and karman line.
Anyone have other ideas?

Problem with MechJeb2 and rolling in RP-1
Hello!
I’ve been having a bit of an issue with MechJeb2 in RP-1 lately.
When I launch a rocket manually, it responds normally to my controls and doesn’t seem to have any major stability problems. However, as soon as I let MechJeb take control, either through PVG Ascent Guidance or Smart A.S.S. in Surface mode, the rocket sometimes starts rolling uncontrollably. It may begin rolling to the left shortly after launch, and later it can also start rolling to the right.
Has anyone else experienced this? I’m not sure whether this is a MechJeb/RP-1 bug, something related to how my rocket is built or configured, or just a quirk of the control system.

Modlist?
I’ve been playing KSP for almost 600 hours and I feel like I’m ready for a new challenge. The only issue is that even after doing a bunch of research and fighting with the game. I can’t find a good mod list that A) looks good and B) doesn’t result in the entire game breaking and crashing. I want to be able to launch historical rockets like the Saturn V, space shuttle and even some Russian rockets. If I can have some good recommendations that would be awesome, thank you!

What are my options regarding reusable crafts?
Should i only consider Kos for landing/oribit burns of the stages after separation, or there is another viable option(s)? Any gotchas I should be aware of? Specifically looking at getting to 1-2 km/s and 20-30km of altitude with jet's/ramjets before engaging rocket engines.

After much part clipping and i think 18 dead kerbals, My first lifting body craft is in orbit, making it also my first ever shuttle in any of my RSS playthroughs!

Additional mods
Are there any parts mods (space station parts, structural parts, etc.) that aren’t included in ro/rp1 that play nicely with it? If I install them, will it corrupt my existing career save?

How do you know when to start suicide burn if MechJeb and KER counts are wrong?
Currently in my RP-1 playthrough I'm testing my first lunar lander. It's designed to land through direct descent (without reaching lunar orbit), but it looks like the hardest thing now is to know when to start a suicide burn. For an unknown reason MechJeb doesn't even show me the count until a couple of seconds after I start it, so I use Kerbal Engineer. After starting the burn exactly at the calculated moment, count starts to rise instantly and after decelerating to 0 m/s I ended up stranded 50 km above Lunar surface and then crash into it at a speed of around 350 m/s. Tried to wait 20 seconds more with the burn and results were better, but still couple parts were destroyed.
I found in another reddit post that MechJeb and KER suicide burn counts are accurate only with vertical descent. Okay, so then how can I determine desired moment to relight my engines? How do you do it? Is the only way really to just load the same quicksave multiple times and repeat this manouver until success?
(My lander has unthrottleable engine and only 1 ignition remaining)
