After landing, it started to work and found ice a few centimeters under the sand. But a few days after a sand storm blew over the Lander and because of that, its solar panels that recharge its batteries ran low and stopped working. This sand storm went on for weeks and Houston (main control) thought that everything was over. But when the sandstorm went away the solar panels started to work again and after a short time the Lander got energy again. After this it went to work again but in November the Martian winter came and it stopped working again. On November 2 the last data was sent to earth. Now the representatives from NASA hope that the lander survives another disaster, like the sandstorm. Because of this mission to Mars, many people now know more about the soil on mars and can wonder if there ever was life on that Planet.
