Not only does the rover send messages directly to the DSN stations, but it is also able to uplink information to other spacecraft orbiting Mars, utilizing mainly the Mars Reconnaissance Orbiter and Mars Odyssey (if necessary) spacecraft as messengers that pass along news to Earth for the rover. The respective spacecraft mainly "talk" via their UHF antennas. The Mars Reconnaissance Orbiter carries an Electra UHF payload with the capability of helping navigate the Mars Science Laboratory safely toward Mars. The Ka-Band package aboard the Mars Reconnaissance Orbiter can serve as another possible pipeline to "talk" to the Mars Science Laboratory (read more about the Mars Reconnaissance Orbiter Engineering Instruments).
