. In all the math that's used to work out gravitational effects, it's the Gravitational Parameter of the Sun that's used, and that's been measured to 12 significant figures.

That has not been my experience, or at least, not entirely. Climbing down from the 2-man landercan to a Hitchhiker or a science lab that's attached to its bottom works fine. I've been doing that on my Cheddar-class landers since 0.18. Climbing up from a Landercan to a Hitchiker or a science lab attached to the top of the landercan, however does not; I'd just assumed that Squad didn't make the landercan so its ladder extended above the door.

Specific positions, yes. Specific time intervals.... that gets a bit hinky. Note: Use radians with all the below equations, not degrees. Given a specific point on your orbit, determining your time to or since periapsis is plug and and play. Solve for True Anomaly (theta) from current radial distance from the sun's center®, semimajor axis (a), and eccentricity(e). Calculate Eccentric Anomaly (E) from True Anomaly. (Fixed equation, 3/11) Calculate Mean Anomaly (M) from Eccentric Anomaly. And from Mean Anomaly and Orbital Period (p), you can find the time since Periapsis (tp). Position along an elliptical orbit as a function of time runs into the issue that there's no closed-form equation for going from Eccentric Anomaly to Mean Anomaly. I tend to use Newton's Method when going in the opposite direction.

Most of my flags have been pretty basic. I'll usually name a flag on the First Landing Site, and if I have to do a surface visual survey, I'll usually plant a flag on at least one of the sites. This sheet contains all the flags that have been currently planted in my Career Save.

Mass is trivial to get from ground-based observations if the body has a satellite. If the civilization has observed the body long enough, they'll be able to observe a transit of a star. That'll get both radius and surface gravity, and atmospheric composition.

I use Modulemanager to do the following.: All probe brains and Pods have both Mechjeb functionality and Protractor functionality. All probe brains have full level-3 pilot capability. Every crew-containing part has 10 units of Kerbal Attachment System storage per passenger seat. The Karbonite converters all have about 10 units of built-in Karbonite storage,to use as a buffer so I don't need to slap on small tanks for my converter/miners.

Yes, the photon has experienced no time. From the viepoint of the photon, (inasmuch as can be said that the a photon can have a viepoint), the universe has zero thickness in the direction of its motion, thanks to relativistic length contraction. So to the photon, its source and destination are in the same place. That said, the photon doesn't /actually/ bounce off things. It goes from its source, hits an atom, and the atom absorbs its energy. Then, after some finite amount of time, the excited atom emits a photon of the same energy as the one that struck it..

I wound up recently building a probe that used one Goo Pod, and was balanced for thrust and translation, with the help of RCS Build Aid and the Offset Tool.. Looking back at it, I'm not /entirely/ sure how it works, but I suspect that the effective "Center of mass" of the Goo Pod part is actually on the backside of the pod, which meant that I could use the Offset Gizmo to push it far back eoung on the OKTO-2 Probe brain to keep it stack balanced. Pushpin Probe.craft That said, I'd quite like an inline goo pod, too.

Ah, fair enough. I was assuming chutes for some reason. Can't imagine why. Objection withdrawn; you may continue beating the witness.

TT-70 radial decouplers. In general, they provide sufficient separation from the central stack that I've never needed to use separatrons to avoid boosterscrape since 0.16, even with the largest radial boosters.

"Now the ion engine just doesn't have enough thrust to [perform the plane change] in one pass (or even a few). " If the problem is truly "insufficient thrust to make the plane change in one pass," I stand by the statement. Infinite fuel isn't going to allow him to make the plane change in one pass, as the thrust will be, at best, the same as if he had not used infinite fuel.

Infinite fuel isn't going to change the amount of thrust your ion drive puts out.

Absolute value always results in a non-negative number. You get a Zero.

If you're not adverse to using mods, and you've got the torque for it, watching Mechjeb's Rover Stability Control is amazing. On the Mun i'd wind up routinely ramping crater rims as 20 m/s, and the worst that would usually happen was that I'd have to stop and repair wheels. On Minmus, I'd drive off thousand-meter cliffs and spend several minutes bouncing before the wheels could be repaired. THere was little enough gravity and more than enough time to get the wheels under the rover. This was not a problem for the stability control.

The problem is that once you've put on about 900 m/s in LKO, you're on an escape trajectory from Kerbin, and thus, won't be coming back for another periapsis kick.

I am the .What are you?

-3 ... is a magic number. Yes it is, it's a magic number.

I generally design so they don't have farings. Even with the extra mass, for the vast majority of my vacuum spacecraft and landers (which tend to be in about the ten ton range or higher), two radial LVNs beat a single chemical rocket of any type for delta-V. Having more than twice the specific impulse really is that good. It will be interesting to see if the upcoming changes that have atmospheric pressure change thrust instead of fuel consumption make me reconsider using LV-Ns on Dunar landers.

Even before the recent changes to the poodle and the Mainsail, the original Kerbal-X had enough delta-V to get to Jool without gravity assists. Safe landing anywhere in the Jool SOI other than Laythe was right out, though. I only had a few dozen m/s of delta-V left in the tanks when I crossed the Jool SOI boundary back when flew the mission in 0.21

It works in the background. So if you've built a Karbonite miner or refiner that can operate without any action from the player once started, it will fill its tanks and/or refine its fuels while you go do something else.

I am the eye in the sky, looking at you. I can read your mind. What are you?

Batteries don't count for the contracts. The satellite needs to have something that can generate power: either solar panels or an RTG.

Yeah, it's plenty of time on the typical Dunar arrival. As I recall, it's typically more than a day from the edge of the SOI to a low Dunar Periapse. Duna's not Moho, after all.

The 1x1 structural panels do not allow fuel crossfeed, so the fuel-seeking algorithm can't find the tanks through them. Either use a part that allows fuel crossfeed to mount the tanks, route the fuel around the panels through parts that allow fuel crossfeed, or run a fuel line from the tanks to the panels to override their fuel crossfeed setting.
