As the probe creeps over the surface, it drills holes to take soil samples. Scientists on Earth notice that the Sun shines straight down into one of the holes. At the same time, 10 kilometers due north, the shadow of the vertical antenna on the main landing craft allows the scientists to deduce that the Sun is 15 degrees from directly overhead.
