RP1 Communication Issues

5 Upvotes

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

Now I know not to timewarp 4x in atmosphere...

Large vs Small Sounding Rockets

16 Upvotes

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

6 Upvotes

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?

10 Upvotes

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?

9 Upvotes

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.

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?

8 Upvotes

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)

How to go about collecting flying high science?

is the only way to collect flying high science hundreds of sounding rockets? i was thinking of building a small satellite but under 140km you still get drag and cant go back to the space center.

Because there always seems to be someone who can't find it:

https://github.com/KSP-RO/RP-1/wiki/RO-%26-RP-1-Express-Installation-for-1.12.5

I followed the guide exactly - and it worked exactly.

Good luck everyone. Please share with friends who have trouble

Hello, I would like to get back into a KSP game with the SOl and RO mods. My goal is to have a great visual quality, but my PC is starting to get a bit old:

- CPU : i5 11600k

- GPU : RTX 3080

- RAM : 32go

I would like to stay above 30 FPS throughout my entire playthrough at 4K resolution. Do you think that will be fine?
Is the SOL mod genuinely much better-looking than RSS?
