By definition the word inquisitive means to be curious or inquiring. This suits the name of the 2020 rover well because the goal of the rover is to collect data, analyze data, and collect new information about Mars. We are all inquisitive about Mars and what role it might play in our future, and even what role it might have had in our past. I also think inquisitive is an excellent option because the Curiosity rover had missions and goals similar to that of the new 2020 rover. Also, the 2020 rover will be the younger sibling to Curiosity and what better way to represent that than choosing a word with a similar meaning. Since Curiosity and the 2020 rover are similar goals wise and are siblings, I think that the names should be similar as well, which is why you should choose Inquisitive for the 2020 Mars rover.
