Spirit takes temperature on Mars AFP

The six-wheeled Spirit rover has taken Mars’s temperature for the first time as it readies for its first roll across the red planet next weekend, NASA said today. During daytime, martian rocks were colder than objects made up of fine particles, said Phil Christensen, the scientist tasked with the temperature readings. “On the ground, the warmest temperature is around five degrees Celsius and the coldest is -15 degrees Celsius,” he said.
