At the start of the science unit we did 1 or 2 questions about space. Mine was what is the rover on Mars. The several rovers on Mars are different models. They explore Mars and can do what a human can do but they don’t need any thing to keep them alive. The thing they do need is a batterie if it runs out it stop moving around Mars. We can interact with them pretty well. We can control them or program the to go in a certain direction. The latest rove sent ciriosity is the latest and greatest rover sent to Mars. The other models like spirit is a model nasa made a lot of and a lot of them broke down and the first one was very small and got stuck. I found out this information by researching it on the nasa website in my own time.
