Orbital Decay Even Outside Atmosphere??

@Gozinya well at least they wont fall out of the sky on their own. lol

@SelectAKey locking pro/retrograde has the same decay rate, as far as I can measure. The decay doesn’t happen when warping or when the craft isn’t selected.

does locking pro/retrograde affect decay rate?

@zeropol thanks for testing and confirming in Droo orbit. I’ll have to try more planets and orbits.

Did a second test in solar orbit, the same, but when I set time to 1/20 the apo was increasing ( the peri still decreasing) and the semi major increasing as a result.
So, maybe it is not always "decay" ?

wow ! strange ^_ ^
So I tried, like you, with the same result. ( the apoapsis also decrease ) Only tested in low Droo orbit.
Because it only happen in speed x1 and x4, it may be calculations errors/rounds that builds up.
Maybe someone have a better explanation ?

edit : I only tested a 150km circular orbit, the decay was about 20cm/sec, it would takes 34 real hours in 4x speed to deorbit, so I guess it is not gamebreaking.
Still, it is surprising.
