help me find a mod for my mission idea

[theroundcow]

tl;dr i want kerbals to collect 'artifacts' that cue certain events

i want to make a gameplay scenario where kerbals must discover 4 artifacts on kerbin in order to discover and track an asteroid/new planet in space.  i was imagining just drilling/mining within a designated area in order for the player to collect the 'artifact'.   once all 4 are collected youre able to track a new planetoid from the tracking center.  obviously with the intention to go there.  any mod that can do that?
