Artist concept of a 1984 mission to Mars, a pair of Rovers (Viking on Wheels) would follow up and extend the 1976 Martian explorations. The Rovers would gather scientific data from several wide-ranging areas and send it to the mother Orbiter for relay to Earth. Two pairs of rovers could traverse up to 5 kilometers (3 miles) daily each and help one another as needed.
