"Unlike Spirit and Opportunity, Sojourner could not directly communicate with Earth and had to rely on the lander to transmit messages about its health and travels. So when contact with the lander, which was designed to last one month, was lost after three months, ground controllers were not sure what became of Sojourner."

"The lander's silver-zinc battery was only capable of being recharged about 40 times, as a consequence after about 40 sols, the battery was not able to keep the lander warm at night. The exact reason for the final failure of the lander is not certain, but it was probably due to an electronics failure due to the very cold night-time temperatures that were experienced in the final weeks of the mission."
