Answers to Where does MSL end and Curiosity begin? explain the difference. There was much fanfare for the naming contest for the Perseverance rover, but I don't know what the mission is called.
Question: 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? Will it also be a "science laboratory" while in transit to Mars?
