Recover launch stages in KSP
Solution 1:
The problem with this is that any on-rails object below 25km in Kerbin's atmosphere will be deleted, as it is assumed it burnt up/impacted. In order to recover stages, you will need a mod. The two major mods for this are StageRecovery and DebRefund. They both do the same thing, but StageRecovery has an in-game settings panel.
