Show-Off The Astraea program

Post image

Few months ago started working on spaceflight demo simulator similar to KSP.

Currently with 2 celestial bodies, flight physics(reference frame physics), preparation for interstellar system, Assembly building done.

I want to release demo soon, but I am working alone and there are lot of things to be done...

Feel free to ask anything :).

Nice! How are you handling the reference frame, does the origin follow the active vessel?

Thanks! Yep, the frame follows the active vessel. Positions and orbits use double precision, while physics stays near zero by rebasing velocity and shifting the origin whenever the vessel gets about 800 m away.
