NASA's Mars 2020 rover looks virtually the same as Curiosity, but there are a number of differences. One giveaway to which rover you're looking at is 2020's aft cross-beam, which looks a bit like a shopping cart handle.
JPL is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.
