Mars Polar Lander and Climate Orbiter
The Mars '98 mission was made of two spacecraft called the Mars Climate Orbiter and the Mars Polar Lander. The Orbiter was going to orbit Mars and search for water. The Lander was supposed to land near the south pole and dig for water.
The mission was to build upon the discoveries of the Mars Pathfinder and Mars Global Surveyor missions. But both spacecraft were lost when they reached Mars.
