The successful investigation of the Martian arctic by NASA's Phoenix Mars Lander has come to an end.
Mission engineers stopped receiving signals from the lander and believe its batteries have been depleted.
In recent weeks, the spacecraft faced shorter periods of daylight, dustier skies, and colder temperature that
caused power supplies to diminish. Eventually, the amount of energy needed to operate the spacecraft
exceeded the amount it could generate. Phoenix exceeded its planned operational life of 90 days, and \
returned scientific data for more than five months.
A dobro, nije ni bilo za očekivati da bi mogao preživjeti zimu.
