This answer to What is the equivalent of Curiosity's “MSL” in the context of Perseverance? What's the official name of the mission? Are the distinctions similar? got me thinking that answers to Where does MSL end and Curiosity begin? explain the difference, but I'm not sure what science the "science laboratory" (the "SL" in MSL) did apart from the rover's work.
Question: Did the Mars Science Laboratory do any science that wasn't done by Curiosity proper?
