Re: Orbital Mechanics and Astrodynamics
#2Go play a bit of KSP. NASA employees have stated that Kerbal Space Program has given them an intuition of orbital mechanics that a degree didn't.
And working with things that make you go _slower_ when turning on your engine to push you in the direction of travel needs intuition to even begin. Yes, once you get to the other side of the planet you are orbiting, you are going slower than if you didn't use your engine at all.

The issue with ksp is that you first need to figure out the rocket design before you start on orbital mechanics (that's why I ended up building my own web simulator for that part anyway, and also because ksp doesn't support my OS)

The design requirements are pretty forgiving and as I recall there are some pre-built rockets you can use.

Is it public?

Sure, didn't want it to seem like an ad, also because it's not quite ready for prime time, I still intend to make a better UI... https://lgms.nl/p/badgravity/
For something ksp-like, I guess the easiest is to press "play" on the Pluto scenario on the left. Note the hints in the top left. Trying it myself now, it seems the scenario is set quite quickly, so I'd set the simulation "steps per run" to maybe 5, and the thrust should be something on the order of 1 (I thought the scenario data should have set that appropriate to the craft but apparently not)
Edit: oh yeah and it expects arrow keys and a scroll wheel, there is no button overlay implemented for mobile yet

Thank you, it's really cool!
I started something similar, but way less sophisticated. Basically i implemented a n-Body solver in Julia, compiled it to Webassembly and did the drawing with canvas, like you. This motivated me to work on it again.

Come on, it's not rocket science.

100%. It’s obvious that text based learning is not the best for many fields. An image, diagram, animation or game mechanic can make concepts “click” much quicker and better. With the ever increasing sophistication of society we need to focus on better ways of learning.
On the other hand, text is the universal interface…

#10Off topic but I have never understood this quote. can anyone please explain. "In order to go fast, slow down, anybody who has learnt orbital mechanics know this"
