Got this game on the Steam Sale. Having a devil of a time getting these ships to rendezvous. Who knew rocket science could be so hard?

Well, I haven't been able to land on the Mun yet. That's like rendezvousing with the ground, right? Also Jed and Valentina are dead although the last was kind of predictable since I wanted to see what would happen if someone did am EVA during the descent.

It's more forgiving of loving up the landing, and cheaper overall. The trip is longer (only matters if you're playing with life support) and the reentry is steeper assuming you're not circularizing on the way back (why would you). It's also made of mint ice cream, which is a major point in its favor.

Minmus is the gold standard for a non-kerbin launch facility as well. Really the perfect little moon.

when coming back to kerbin from the mun or minmus, do you guys usually do a few passes airbreaking or just dive right in

You can do whatever you want, but diving right in takes the least amount of time.

Heatshields and multiple passes are moreso for interplanetary travel and thick atmospheres (thinking of you, Eve!)

Also really heavy rockets if you piled them with unnecessary garbage like "extra passenger space"

I don't know about just doing a roll to even out heating like in KSP, but now that I think about it Apollo capsules did do a little zoom climb maneuver during reentry to reduce the load on the heat shield. https://www.youtube.com/watch?v=MTKHqfloB7Q&t=901s

ikanreed posted:Is that a real thing or a kerbal thing? If you've got enough pieces on the outside of your rocket and enough control authority to do it stably, it seems to be at least possible in KSP, though the effectiveness probably isn't that high and the design requirements are probably non-trivial. I've seen the temperature gauges zooming up and down as my less-stable ships tumble back and forth through the atmosphere trying desperately to keep their heading.

Apollo also did a slow roll a lot of the time so the Sun would heat the spacecraft evenly

ikanreed posted:Is that a real thing or a kerbal thing? It's a least a kerbal thing. I've done it once or twice when I got concerned about overheating a spaceplane. I'm going to come out of it at something like 20km, so I have plenty of time to work out of the stall before hitting the ground. ...probably.

fun fact air brakes can be yaw and pitch axis control surfaces if you enable it

I wish things like atmospheric heating and antenna ranges weren't effectively dependent on a mixture of guesswork and trial-and-error until you've done it enough times to develop a gut feeling about it, especially since they're both largely tied to interplanetary flights that already have a lot more time, planning, and resources invested into them.

You can calculate the range quite easily. Two seconds with a calculator. Square root of (power 1 in watts * power 2 in watts) in meters. With the 250G full upgrade of tracking station, you can almost, but not quite, reach across kerbin's full orbit to a 2G sattelite 2G*250G=500GG Sqrt(500GG)=22ish GM(Kerbin's apoapsis is 15GM and periapsis is 13GM.) The math going the other way is easy too. Required Power = (Max Range in meters)^2/250,000,000,000 Heating otoh is a real world hard problem, that I think real engineers solve by simulating. You're already playing the simulator.

Consider this sort of body shape for landers: https://www.youtube.com/watch?v=GFBeVQ3STZ0 I find that not losing the mission to a tipped-over lander outweighs the efficiency loss of multiple engines.

I've Evel Kenivaled myself off of cliffs to get a launch angle before, and also used rovers to prop my spacecraft up. One of my Duna landings didn't have enough torque to right itself with the reaction wheels, so instead I rolled my way to a suitable dune, poked the nose over the crest, and lit the fuse. I lost a bunch of poo poo in the process, but doesn't matter made orbit.

It'll fit around a stack of lander cans too if you want to take multiple people, and you can get all tucked in a 2.5m fairing pretty easy

This is what i usually fly to the mun the first time, more or less. Fairing not really necessary. 4x symmetry around the lander cans, there's a heat sink on the bottom and you can jettison those tanks if you want but you wont need to, it has like 2800dv in vacuum so the landing is usually partly powered.

The Mun? I'm doing a weird career save where I don't care so much about researching new parts and just use what I have to get where I'm going. I know that people have gotten far using only the starting tech, but I'm not that masochistic. This was my first mun lander. It weighs too much for the level 1 launch pad, but it has exactly 30 parts so I didn't need to improve the VAB just yet. It does leave the lander in orbit, however, so you're not going to get "return from mun" contracts with this one... ... unless you put a parachute on the lander (a 31st part) and are careful about your descent and ascent efficiency. Then, if you back the lander very carefully into the atmosphere, you can just about land it without it burning up. Here's the lander separating from the transfer rocket. I made this a flight for two so that we can have a Michael Collins esque figure steering the transfer rocket in case we need to rendezvous from the other side. The trick to this particular lander is that its reaction wheels have the strength to pick it up on the mun. If it lands on a slope, just lay er down and use the reaction wheels to stop it rolling too fast, then wait for it to come to rest. Just remember that the lander battery is switched off at launch in order to prevent it from draining before we reach the mun. Azza Bamboo fucked around with this message at 00:55 on Jul 25, 2020 |

We had 2 tanks of O2, 75 units of RCS, 5 engines to feed, half an EVA’s worth of CO2 scrubber, and a whole other constellation of propellants, consumables, spare parts, and comms gear...and also a canister of FOOF, a container of plutonium, a pint of ClF3, and 2 dozen pure Nitrogen crystals. Not that we needed all that, but once gets locked into a rocket fuel/parts collection, he tends to push it as far as he can.
