Mars is a Roman god of war. His sacred animals were the wolf, the woodpecker, and the bear. Picus was a woodpecker who was very sacred to Mars and actually became a god himself. I chose the name Picus because he was a woodpecker. Woodpeckers drill into trees. The new Mars rover will drill into Mars. Picus was a very good friend of the god Mars. The new rover will be a very good friend to the planet Mars.
