Super Explorers takes you back in time to the medieval days when people lived in castles and knights roamed slaying dragons and rescuing beautiful maidens: - Castles were fortifications made of stone built in the Middle Ages to control land and protect nobles from their enemies. - Many castles were surrounded by large water-filled moats. - Most castles have secret passages so the inhabitants could hide or escape if the castle was taken by enemies. - Castles had towers and arrow slits from which the soldiers could see any attackers at long distances. - Knights swore their loyalty to the king or noble of their choice. - Knights needed armor, weapons and a well-trained war horse, which he depend to take care of him in battle.

There are about one million robots in the world. Some say that robots will be recognized as their own species by 2040. The first "humanoid" robot was built in 1939 by Westinghouse. There are two robots exploring Mars, named Spirit and Opportunity.

Spiders are amazing creatures. There are more than 38,000 known species of spiders, and a human is said to never be more than 3 meters away from a spider. Spiders are NOT insects. Spiders have eight legs and two bodily sections, while insects have six legs and three bodily sections. Some spiders are poisionous (and deadly), but most are not. All spiders produce silk, which many species use to spin webs and capture their prey. The largest spider is the Goliath birdeater. It can grow to be 28 centimeters wide and have fangs that are 2.5 centimeters long.

Super Explorers take you deep into space to see the planets in our Solar System and beyond: - Our Solar System has 8 planets, 5 dwarf planets and many minor planets. - Most planets have at least one moon like Earth, but Jupiter has 69 moons and Saturn has 62! - The Sun's gravity keeps the planets in our Solar System circling around it. - Mercury is the closest planet to the sun; the temperature there is 117˚C (243˚F). - Neptune is the farthest planet from the sun; the temperature there is -216˚C (-357˚F). - Scientists think there may be extraterrestrial life on Enceladus, a moon of Saturn, because there may be liquid water under the surface!
