Morphology

booster = boost (transparent) = boost + er

The rocket-stage sense is a straightforward instrumentive extension: something that gives a boost.

Etymology

Booster comes from the verb boost meaning 'to lift' or 'make stronger' plus the ending -er meaning 'one that does a thing'. So a rocket booster is the part that gives the first big lift to get the vehicle into the air.
