The Junkyard Missions
From Starsonata Wiki
The Junkyard Missions lets players exchange unwanted items for items that they deem better. Usually these items have good value for the potential credits lost during the exchange, but have other drawbacks for balancing reasons.
Every item you can obtain from The Junkyard, or mission chains that starts in The Junkyard, have some sort of mechanic that makes them disposable, meaning that the item will not be permanent. It either means the item is sticky, you can’t scoop it, it is a missile or a tweak, or the fighter does not return to the ship after you have launched it.
