Mars Polar Lander Mission (1999)

It was launched on January 3, 1999. It is also called as Mars Surveyor ’98 Lander. It was created to study the surface of Mars. NASA was showing a doubt that it seems to be water under the surface of Mars, for this reason they sent a Mars Polar Lander. There were two probes with it which were specially created to affect the surface of Mars and other technologies there, which were known as Deep Space2. They were the first one to be landed on Mars and the purpose was to dig an ice on Martian surface.

But unfortunately it was crashed and this mission got failed. This spacecraft was crashed due to the problems and errors in software designed in it and it hit the planet with high and fast velocity. After this disappointment, NASA rebuilt its unmanned Mars investigation program and chose to fly less difficult missions dependent on the air-sack lander and wanderer innovation from the very effective Mars Pathfinder and Sojourner mission of 1997.
