Need help with parts disappearing after 2.5 km

[jchad]

I am trying to build a plane that will drop autonomoaus science probes into different biomes on kerbin so that I could recover them later for their science. But no matter what I do they all disappear after 2.5 km, even if I have a probe core on them, etc.

Any ideas here?

Don't feed the troll.

Im sorry. Can you clarify that

All objects that are in an uncontrolled free-fall are auto-deleted after they are more than 2.5km away. There are two reasons for this:

Objects further than 2.5 km are "un-loaded" from the physics engine and put on rails, to lighten the load on the CPU.

Objects on rails that are on an impact course with a celestial body are deleted as having "crashed". This includes spent stages that are discarded during a launch, or any other parts your craft sheds while in Kerbin's atmosphere.

In short, the game is programmed to do this.

There are "mod" to prevent the disappear of the object. But the calculation part for reentering atmosphere, only done in 'focus' object. So, your parachute (for object further than 2.5km) will not open.

You will have to manually land them for them to stay, or, at least remain under 2.5 k from them until they have landed on their own. Not an easy feat when you also have to fly the plane low in order to stay in the 2.5k range. Try dropping them from orbit and landing each one separately. They will then remain until recovered.
