Didn't seem like much. Once you drive away Pirate Faragut Battlecruiser, you get 5 Wreckage Components. There could have been a mission to recover those, but my exploration vessel is an Anaconda, so i couldn't land on Stepping Stone Base and had to sell them at a black market for a glorious sum of 300 Cr.
Lol, don't spend it all at once!
