This trike and trailer combo is the first set in the series to reflect the action of the theme (what do the minifigs do?), which is to find and research the possible beneficial uses of ores and minerals. In this theme, much like TLG's Space Port theme, these ores and minerals just happen to be found inside meteors and asteroids which are often striking on the planetoid where Base I is located. In addition to scanning the skies, the droid can also search for meteors/asteroids buried beneath.
