Mars Polar Lander
The Mars Polar Lander (MPL) was launched from Cape Canaveral Air Station Space Launch Complex 17 (SLC-17) on a Boeing Delta II rocket on January 3, 1999. The lander was scheduled for a soft landing in the south-polar region of the planet. Contact was lost with the lander during its descent onto the Martian surface on December 3, 1999, and after a series of efforts to communicate with the spacecraft failed, on January 17, 2000, the Jet Propulsion Laboratory, who managed the mission, declared it a loss.
