In East Africa, the Serengeti comes alive when wildebeests journey across treacherous terrain to find the best grazing locations. Every year, approximately 1.5 million wildebeests migrate over 1,800 miles or nearly 3,000 kilometers searching for rain ripened grass. Prior to their journey toward Kenya, they graze on the grasses of the Serengeti in Tanzania before the rainy season comes. As they search for food and water, they endure crocodile-filled...

Engineers and architects are creating bridges that combine the best of both art and design. Bridges are no longer just a tool to get from one side of the river to the other. Some bridges have the goal of being aesthetically pleasing and efficient for pedestrians. Others rely on the cantilever design to span a distance equivalent to three and a half jumbo jets. Bridges are often classified by their structure and how the forces of tension, compression,...

With the retirement of NASA's space shuttle fleet in 2011, the role of getting people, satellites and other instruments into space falls to private companies. As of June 2011, there have been only 523 people to reach the 100 kilometer mark (considered human spaceflight), and only 24 have traveled beyond low Earth orbit. It is projected that within ten years, the number of people who will have flown into space will increase by about 600 percent due...

Christmas Island, discovered December 25, 1643, is just a speck of land in the Indian Ocean. The annual red crab migration at the beginning of the rainy season, however, is so massive it can be seen from the air. It has been named a wonder of the natural world. This program follows this terrestrial arthropod from its rainforest burrow, across dangerous landscape to the ocean to mate. The park offers the perfect forest ecosystem for the Christmas...

The role of getting people, satellites and other instruments into space is falling to private companies, especially with the retirement of NASA's space shuttle fleet in 2011. Reaching an altitude of 100 kilometers is required to be considered spaceflight. There have been just over 500 people that have reached this mark and only 24 have traveled beyond low Earth orbit. It is projected that within ten years, the number of people who will have flown...

The Periodic Table is organized with elements specified in rows, or periods, according to increasing atomic number. Metals are on the left of the periodic table, while nonmetals are located on the right. Some in the middle are called metalloids because they have characteristics of both metals and nonmetals. The periodic table is purposely arranged into vertical classifications called groups. Columns of elements help define element groups. Some of...

Advanced digital technology using 3D-terrain maps, laser pantographs, digital photographs and satellite data is increasing our visual understanding of architectural structures of bygone eras. The multi-faceted world of digital archaeology aids researchers by supporting data management and by making visual presentations more realistic. The ancient city of Troy is re-discovered in this engaging program that fuses complex technology to uncover the past...

Automobiles have evolved in many ways over the years, with increasing fuel economy, reliability, handling, and comfort. However, automobile manufacturing is in a new era, focusing on safety while incorporating impressive new technologies into our transportation needs. With a growing population, there are subsequently more people driving and more automobiles on the road. With more congestion and traffic, the likelihood of accidents seems imminent....

Strength and stability are important factors in airplane or space vehicle design. Engineers create vehicles that are strong enough to flyEffectively and efficiently by using specific materials and structures that are lightweight and durable. Important decisions are made regarding the materials that are used to make the fuselage, wings, tail, and engine. Many airplane materials are now made of composite materials that are lightweight, yet stronger...

For many years the Hubble Space Telescope has collected breathtaking images of the cosmos with remarkable clarity. Now, ground based telescopes are fighting back. They are combining the sight of several instruments and correcting atmospheric shimmer. This program presents and explains the designs, uses and output of different types of telescopes used to see our universe. From the Keck in Hawaii, the Very Large Telescope in Chile and OWL, the Overwhelmingly...
