Mars Polar Lander
The Mars Polar Lander , also known as the Mars Surveyor '98 Lander , was a 290-kilogram robotic spacecraft lander launched by NASA on January 3, 1999 to study the soil and climate of Planum Australe , a region near the south pole on Mars . It formed part of the Mars Surveyor '98 mission . On December 3, 1999, however, after the descent phase was expected to be complete, the lander failed to reestablish communication with Earth. A post-mortem analysis determined the most likely cause of the mishap was premature termination of the engine firing prior to the lander touching the surface, causing it to strike the planet at a high velocity.

The Mars Polar Lander , also referred to as the Mars Surveyor '98 Lander , was a 290-kilogram robotic spacecraft lander , launched by NASA on January 3, 1999, to study the soil and climate of Planum Australe , a region near the south pole on Mars , as part of the Mars Surveyor '98 mission . However, on December 3, 1999, after the descent phase was expected to be complete, the lander failed to reestablish communication with Earth. It was determined the most likely cause of the mishap was an improperly ceased engine firing prior to the lander touching the surface, causing the lander to impact at a high velocity.

Mars Polar Lander (sometimes referred to as the Mars Surveyor '98 Lander ) is one of two exploration vehicles of the NASA Mars Surveyor '98 program . Launched on 3 January 1999, 23 days after its partner, the Mars Climate Orbiter , the mission ended in failure with the loss of both craft in separate incidents. After attempts to re-establish communications failed following entry into Mars atmosphere, the lander was declared lost, with the presumption that the vehicle did not survive the descent. |

The Mars Polar Lander was a failed exploration vehicle, and part of the NASA Mars Surveyor '98 program , which consisted of two spacecraft launched separately, the Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) and the Mars Polar Lander (formerly the Mars Surveyor '98 Lander). Mars Polar Lander also conveyed the Deep Space 2 surface-penetrator mission to Mars . The two missions were designed to study the Martian weather , climate , water and carbon dioxide levels, in order to understand the reservoirs, behavior, and atmospheric role of volatiles and to search for evidence of long-term and episodic climate changes. The vehicle did not survive the descent onto the Martian surace, and is presumed to have crashed. Communication with the lander was lost (as expected) prior to atmospheric entry, but never regained on the ground, and the cause of the mission failure remains uncertain. |
