Here's a nice orbit simulation for Chandrayaan-2 mission: https://sankara.net/chandrayaan2.html
From the Wikipedia article -
>> Oberth maneuver, is a maneuver in which a spacecraft falls into a gravitational well, and then accelerates when its fall reaches maximum speed. The resulting maneuver is a more efficient way to gain kinetic energy than applying the same impulse outside of a gravitational well.
>> In some cases, it is even worth spending fuel on slowing the spacecraft into a gravity well to take advantage of the efficiencies of the Oberth effect.
Fascinating! To say the least!
Does anyone know what the teleportation glitch is right at Lunar capture?
Not sure! Author of this tool is here: https://forum.nasaspaceflight.com/index.php?topic=20324.msg1...
He might visit HN if notices traffic from here :)
One pretty accurate way of approximating orbits is the patched conic method where you break your n-body problem into multiple 2-body problems picking the most influential body for specific parts of a journey.
Interplanetary journeys will have three parts ex. earth-craft, sun-craft, and mars-craft.
The glitch might be some noise switching between two different patches.
So, KSP's "Sphere of Influence" ?
I use data published by JPL/NASA HORIZONS interface which provides orbit data for all natural bodies and spacecraft. The "glitch" is because of the data I fetched and used - it has nothing to do with the animation per se.
As of now, the JPL site provides data only until 20th August - the time when I fetched the data a few days back, the data was available until 16th September. This was a "merge" of 3 orbit segments - the Earth bound orbits, the transfer orbit and lunar bound orbits. The former two fit the observed data. The latter was entirely based on predictions. This merged orbit has a discontinuity where the predictions start and that's why there seems to be a glitch.
Once revised data is available from JPL/HORIZONS, I presume the glitch will go away.
