There is a network of dishes set up on earth to send and receive communications from space. It’s called the deep space network (DSN).

The curiosity rover can directly transmit to the DSN if it has line of sight with Earth. There are also still two orbiters around Mars (MRO and Odessy) which can be used as relay stations.
