Viking :The two Viking Lander spacecraft were the first spacecraft to operate successfully for an extended period of time on the surface of Mars. Both spacecraft operated from 1976 through April 1980 and Viking Lander 1 (VL1) continued to operate until November 1982. The Viking Mission consisted of four spacecraft: two identical orbiters and two identical landers. The landers were attached to the orbiters during cruise to Mars.
