What if launching a rocket would be the last thing on your checklist ? This challenge is a bit special, I propose you to build an infrastructure around the rocket, with vehicles, buildings and stuff to prepare launches! Facilities : Fuel services : Mine your own fuel (you can combine multiple fuel tanks to one ISRU using home-made pipelines) +100 Use 3 types of storage for each propellant (each tank is specialized, liquid fuel and oxidizer must be transported separately for safety reasons) +50 Transfer and load fuel in the rocket, once it is ready to laun

My astronaut complex is empty. No hireable kerbals (list is empty and cost for next hire also says 0), none active ( although it says there's 10 active out of 12 max), none available and none lost. I have the 4 starter kerbals, Jeb, Bill, Bob and Valentina. I have no vessels in flight/orbit. I've checked persistent save and changed idx of the 4 kerbals to -1 from 1 (read that -1 value signifies available) with no effect, positive OR negative. I've timewarped in an attenpt to populate the list (read that it might fix it) but again, no effect. Mods are all in working order to the best of my know

I'll get straight down to it: I have a polynomial with a complex variable z and complex coeff's (real parts all zero): z3 + 8i z2 - z + 42i, i being the imaginary unit. I am wondering for which values of z does this polynomial give real numbers, that is numbers with no imaginary part. I know I can write the equation z3 + 8i z2 - z + 42i - r = 0 where r is a real number. However, I am looking for keywords to look up, techniques to read up on and (hopefully) learn, different kind of plots, to be able to plot r as z moves across the complex plane. The mor
