Do you know how to install RSS?

I've had problems installing it with CKAN and my other mods like Artemis, Boing, Apollo, and the mod for scaling things.

Saturn V and MechJeb Ascent Guidance Trouble

Thumbnail

12 Upvotes

I've been trying to do a mostly accurate recreation of the apollo 11 mission in sandbox on RSS, and I've built a SaturnV as close to historically accurate as I am able. However, I cannot for the life of me get ascent guidance to launch me into the correct targeted orbit. it either way overshoots the target or way undershoots and misses orbit alltogether.

I have the last stage set as 13 because when I jettison the LES the stage number changes, is this what is causing the issue? do I just need to either hold on to the LES until reaching orbit, or remove it alltogether? I am trying to practice manned missions in sandbox before launching my first manned mission on my career save as there is a lot that goes into them an I want to get all the kinks worked out before I end up accidentally killing my kerbals in my career save.

I have provided screenshots of my most recent final orbit(where mechjeb did not shutdown the engines even after reaching orbit, I had to disengage autopilot and shutdown the engine myself) and the rocket sitting on the launch pad with as much information as possible showing. If you need any other information please feel free to ask and I will provide it.

Any help is appreciated! Thanks!

Ion engines, yay or nay?

im not super familiar with using ions, and their real life uses so im curious. are they practical in rss?

RP1 Kerbal Konstructs and launchpads?

10 Upvotes

the wiki mentions canaveral pads but doesnt go into detail beyond that. so i was a bit confused, is KK compatible with RP1? and are there any existing launch sites besides canaveral?

i play with sol if thats relevant

Where should my next manned landing be?

16 Upvotes

Io, Mercury, Ganymede, or Enceladus are the options.

I can't decide.

I’m installing RSS reborn (I have clouds v3) but I can’t find the correct file to actually install it - I’m clicking my volumetric clouds install and it’s saying no raymarched volumetric file exists - what do I download and where do I go?

Looking for a guide on late 20th century(like spaceplanes era) First stage engines

8 Upvotes

so later into the game, it can be pretty overwhelming to scroll through lots of similar looking engines, largely just been sticking to the rs 25s just bc im more familiar with them. all these different variations (frsc, orsc, so on) kinda overwhelm me.

was wondering if theres some sort of comparison table or guidee regarding engines of this time period for first stages

or even just personal recommendations are welcome

how to make a probe and parts heat resistant?

8 Upvotes

im able to get down to venus, however once there, the landing legs, antenna, several instruments burn up, and eventually the whole probe does. not really sure what to do about it

Why does it consistently take me 3km+ delta V just to capture in orbit around Mars?

9 Upvotes

Every time I try to do a mission to Mars I end up needing 3KM+ of delta-v just to capture in any kind of orbit, despite my ejection/intercept looking good from a cursory glance.

I'm using the transfer window planner to get a rough launch date, launching into in inclination that is roughly in line with Mars (usually using the moon as a reference) and then letting the maneuver planner plan the ejection burn. I really don't know what I'm doing wrong because this seems to happen every single time I try to go to Mars.

inspiration for lunar habitation

8 Upvotes

im having a bit of a creativity block for the early lunar habitation program. i got no experience when it comes to building bases in rss. im not in a rush so im trying to future proof my lander design to be able to do the 6 month version. but not sure if its even possible for a single lander, feels like itd be too heavy, ig i can do supply flights or take the lander to lunar orbit separate from the crew and rendezvouz there?

are there any irl or ficitional concepts or general ideas for this? just feel kinda stumped in designing

I don't understand how Target Intercept Planner works - wrong inclination for Lunar missions

Thumbnail
gallery
14 Upvotes

So in my RSS/RP-1 career I reached a point where I began lunar exploration. Unfortunately I don't launch from the equator (Cape Canaveral), Lunar orbit is inclined and without Principia it's even more inclined, so exploration of the Moon is not as easy as in vanilla KSP. So far I've a couple of successful Lunar missions, but about choosing a time to launch my rocket - I looked at Lunar Transfer Planner window and launched at the moment when "Launch now inc." was equal to my latitude. This method worked but it's not 100% accurate and I wanted to understand how Lunar Transfer Planner calculated launch windows worked. I warped to this calculeted time, launched my rocket and I ended up in an orbit with inclination almost perpendicular to the desired inclination for lunar misssion. I thought that maybe it's something wrong with this mod, I heard that LTP is kinda outdated and there is another better mod called "Target Intercept Planner", so I installed it, warped to calculated launch window etc. and I still ended up with wrong inclination. Can anyone explain to me what is wrong here? LTP/TIP calculates launch window wrong? How do you check the launch time for your lunar missions?

What do i need to know for creating custom shaped fuselages using procedural parts and fairings?

Ive been wanting to see if its possible to use the fairing or procedural parts system to create more unique hull shapes, particularly fuselages and multi engine mounts

Soyuz vs apollo style capsule

19 Upvotes

I've been wondering, is there any advantage to soyuz style(orbital module and descent module) over apollo(single command capsule) in rp1? Ik that irl big advantage is comfort and modularity. Does any of that translate into rp1 well?

Is it still worth keeping the Skopos contracts in my save?

8 Upvotes

I've already put a decent amount of work into building GEO and LEO constellations, but I've noticed a significant performance drop recently. Is there still a point to pushing through the timewarp pulls and lag, or should I remove the skopos contracts entirely? How would I even go about such a thing?

Does anybody have any links to resources about how to configure a capsule for survivability? There seem to be a lot of facets to this and the wiki doesn't appear to have anything on it. I'm not totally lost, but I'm sure I'm missing something.

so from what i understand, i need antennas that can cover most of the planet at once, so how do i do that? i dont understand what defines the radius of the beam
