This is why you should turn solar storms off- they’re broken and will randomly nuke your crews for no reason at all with no way to avoid them. Just load an earlier save from before the crew died and keep going.

We shall remember them…. ;-)

Wheels are problematic and will break for no reason at all. The simplest way to fix it is to change the mod settings (RealWheels or something?) to prevent wheels breaking, edit the save file to fix the wheels and then reload. Alt+F12 > cheats > fix repairable parts may also do it but I’m not sure.

The rover descent was unstable because it was trying to roll at the same time as dealing with unbalanced mass and thrust; it was only just keeping it pointing straight and adding the extra imbalance from roll thrust tipped it over the edge. And then you overburned the engines at low thrust rather than doing it all at high thrust or none at all. As soon as it landed upside down my first thought was “use the camera to flip it over” but the magnetometer did it too.

Bon Voyage can’t detect Kerbalism RTGs so it doesn’t work well in RO, you need to enable infinite electricity to use it.

When using drive to target mode in Bon Voyage I always remove the last few decimal places from the co-ordinates to avoid the two objects trying to be in exactly the same place at the same time. It also struggles to do long-distance path finding so driving half way around the Moon needs to be done in smaller stages.

The rover landing stage is fine, you just keep throttling down too much and over burning the engines to the point of failure. The rover itself seems to be rear wheel drive only and couldn’t drive off the ramp as a result, enable all four wheels’ motors and it’ll drive better. You should disable the motors before launch and set it to an action group as well as applying the brakes so the wheels don’t destroy themselves.

Moral of the story- check your trajectories in the tracking station before switching vessels. Better to find out you’re missing the target when you can do something about it than when it’s too late.

Both Ceres and Vesta have considerably less gravity than the Moon and are almost trivially easy to land on if you can reach orbit. A rover for each would be a good next step, and/or a cluster of tiny cube sats made of science core + RTG + orbital perturbation experiment to scatter around and speed up the data collection.

And spend some of that 7 million fund reserve on KCT points, what are you hoarding it for?

A bit too much faffing with fuel cells this episode, you don’t need the solar panels on the service module and you can get rid of the waste/waste water tanks to make more room for water. Switching to vacuum scrubbers would help too, they use more power (so more water being made) and also remove the need for LiOH (so more room for water), they’re the best option for longer term missions.

Why did you use PVG to launch from the Moon and then repeatedly break it by messing with the inclination? It was swerving north, then backwards, then south, then north again and wasted a huge amount of fuel.

The pilot on the CM in orbit got more stressed because a) he was alone and b) the other two were on the ground which adds a bit of a bonus, and also c) individuals vary quite a bit even on short term lunar missions so it’s possible that the pilot was above average and the others below average.

You can combine targeted moon landing and landing with rover, but only if the rover targets are in/very near the targeted biome or if you send a big rover that’s more like a small base on wheels to keep them alive for a longer period. For the station, a D-2 with block 2 mission module would tick all the boxes and with a modified service module would hold all the resources needed for the 30 days as well as being a backup in case a visiting crew couldn’t get home on their own vessel.

You can turn off all Kerbalism messages with the pause key, but it turns everything off for every vessel so you might miss something important.

Those ultra imaging satellites need a dedicated S- or X-band relay network to get the data down at anything near real time. Three or four relays that can all talk to each other with S/X band dishes pointed at each other (use the antenna targeting button) and have either dedicated dishes pointed at each satellite or a high power but lower gain/wider beam width dish aimed at Earth, with each satellite pointing a dish at each relay, is the way to go.

Video ended rather abruptly :/

A bit of trial and error with azimuth and elevation on the antenna can get a signal when you’re close to Earth if you’re patient enough. Or maybe put (with set position cheat) a tiny “probe” beside each DSN station to make it easy to target them?

A crewed Mars mission is no easy undertaking: I needed five launches in total including four extremely large rockets that were ~12kt on the pad to get the ship into orbit and assemble it, though it’s possible to do a larger number of smaller/lighter launches including orbital refuelling to get the same result. ISRU for a Mars ascent craft would need to be sent in the previous transfer window because it’s SLOW; I went for just taking a lander that could do the landing and return with the main ship as it was less hassle.

“Interesting design choice”… What is it with dragging spent solid boosters around on first stages?

Switching vessels doesn’t work on debris unless you hold Alt and press ] or [

You could probably double your KCT points in R&D if you spent that huge pile of money you’ve been hoarding.

Adapting the new COG into a fuel tanker would be pretty easy, just swap the life support resources for RCS propellant and you’re done.
