Viking will tell its story in its own voice about its observations on Mars, about the surface, the velocity of the wind, the humidity and pressure of the thin atmosphere, and most important, whether there is any evidence of life now or in the past. Meanwhile, the orbiter remains overhead, keeping watch on the landing site, operating as a relay station and conducting its own science experiments and photographic mapping. Their missions completed, the orbiter will continue circling the planet with Martian moons Phobos and Deimos for many years. The Viking's surface laboratories will remain and may provide landmarks for the first Earthmen who visit Mars. Just as the surveyor stood in weight of the Apollo astronauts.
