Duplicate and off-topic closures are permanent. The question “How do I get to the Mun (2× faster, no math)” has been closed 4 separate times under 3 different usernames. The original question, “How do I get to the Mun,” has been answered correctly. The answer has math. This will not change.

After I decouple the first stage at ~32km, the upper stage immediately begins a slow roll that SAS cannot correct. The roll rate increases with altitude. I've tried adding reaction wheels.

KeedMartin's published thrust curve for the VAJE-7B shows a specific impulse of 320s at sea level. OMQ Issue 14 printed a correction to 308s. KeedMartin has not acknowledged the correction. Which figure should I trust for dV calculations?

I want to get to the Mun faster than the normal way but I don't want to use math or delta-v calculators. Just tell me which way to point. [Edit] I know this is a duplicate of "How do I get to the Mun" but that answer has math.

I'm planning a gravity-assist flyby of Jool to cut the delta-v needed for an Eeloo insertion. Trying to calculate the window manually but the synodic periods don't line up cleanly. Is there an analytical shortcut or do I just simulate it?

At what altitude does atmospheric drag become non-negligible for a long-duration parking orbit? I'm seeing conflicting numbers — some say 70km is the hard floor, others say 69km is fine for multiple orbits. 19.4km was an accident.

NASA has awarded the SOLARCOM contract but hasn't specified what SOLARCOM is for. KerbalX won the bid. Is this a relay network? A deep-space comms station? The Herald's source says it's 'big.' Anyone have technical context?

For a round-trip mission to establish an ISRU operation, which body requires less total delta-v from LKO: the Mun or Minmus? Factoring in the inclination change to reach Minmus's orbital plane versus the Mun's closer but steeper gravity well.

We're trying to verify the KSS Node-2 approach corridor. The published docking guidance document is version 3.1 but Node-2 was installed under a revised spec. Does anyone have the updated alignment tolerances or know where to find them?
