See how geckos inspired new NASA technology that makes things stick to each other in space. Potential future applications might be to grab and service satellites or to salvage space garbage. Part of the “Crazy Engineering” series.
Satellite footage, telescopic photos, and animation are used to teach students about the many aspects of the solar system. Viewers are introduced to ancient astronomers, telescopes, observatories, and space exploration. Students will discover facts about planets, orbits, gravity, revolution, and rotation. The program also features discussions of the sun, comets, asteroids, and meteors. Part of the Real World Science series.
A new transmitter helps protect wireless data from hackers. Other features in this episode include bacteria using DNA to speed their evolution and a new next-generation water harvester that delivers fresh water from air. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Geologists discuss the tectonic forces that have formed the African continent. Evidence suggests that Africa was once separated from Eurasia by an ancient ocean. Once this ocean disappeared, the continents of Europe and Asia collided. Tectonic forces continue to shape the continent, and some experts believe Africa is being torn apart by these forces. Part of the "Voyage of the Continents" series.
The Exumas are a string of small islands in the Bahamas. This documentary explores the geography of the islands and provides a window into their natural features through the eyes and thoughts of a young woman who lives there. Underwater and time-lapse imagery are used to show a side of the Exumas that few people, even those lucky enough to have visited, have ever seen.
How does NASA spot asteroids that maybe getting too close to Earth for comfort? It takes a lot of data gathering by computers, satellites, and individuals. Asteroids are tracked and monitored frequently by astronomers.
Fly into this high-tech career and learn about satellites, airplanes, and maybe even flying cars of the future. Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. Part of the "I Can Be Anything I Want to Be A to Z" series.
Summer ice retreat in the Chukchi Sea between Alaska and Russia is a significant climate change impact affecting Pacific Walruses. Scientists follow walruses in their summer sea ice habitat and show how United States Geological Survey (USGS) biologists use satellite radio tags to track their movements and behavior. The information identifies areas of special importance to walruses during sparse summer sea ice.
With support from the National Science Foundation (NSF), Forrest Masters and a team at the University of Florida are developing new technologies to help engineers and scientists better understand the strong, high-wind storms that batter communities along U.S. coastlines. The National Home Education Research Institute (NHERI) has the broad goal of supporting research that will improve the resilience and sustainability of civil infrastructure against the natural hazards of earthquakes and windstorms. Part of the "Science Nation" series.
What is the future of human presence in space? How might things be different if there had not been a Cold War and a Space Race? What does humanity gain by venturing into the solar system? Three events are key moments in the conquest of space: the R-7 rocket launches the first satellite into space, President Kennedy's speech announces the United States race to the moon, and Neil Armstrong walks on the moon. Part of the "Butterfly Effect" series.
A documentary film highlighting recent and past USGS (US Geological Survey) research in the Lake Tahoe Basin. It features USGS science activities conducted by hydrologists, geologists, geographers, computer modelers, and biologists. Some of USGS science detailed includes water quality monitoring, streamgaging, and use of aerial photography. The use of consistent, reliable, long-term data and maps are crucial for evaluating and maintaining the lake and basin.
The last decade of the 20th Century sets us on course for the next 100 years. With inventions like Global Positioning Satellites and The Hubble Space Telescope, the inventions of the 1990s help us see where we've been and where we're going. Additional inventions include: the wind up radio, camera phone, the Mars Pathfinder, and the neurotropic electrode.
For millennia, hurricanes have threatened the Eastern United States, the Caribbean, and parts of Latin America. But changes to global climate have serious consequences for the future. For example, rising sea-levels mean that storm surge from hurricanes will impact ever further inland. In episode three, specialists discuss why they believe that hurricanes will become less frequent but increasingly powerful. Insight and interviews from leading experts such as Nobel Prize-winning climatologist, Jean-Pascal Van Ypersele, explore the preparations needed to withstand a super storm. Part of the "Hurricane, the Anatomy" series.
Meteorologists studying clouds in Europe are learning about the microphysical processes that occur naturally in clouds. This knowledge helps researchers gain new fundamental knowledge that can help improve weather and climate forecast models. Students will discover how scientists study cloud formation by generating artificial clouds in a laboratory. Scientists research how clouds originate and how they react to surrounding natural elements. They will reveal how microwave radiometers, lasers, and satellites are used in researching cloud development.
The cathode ray tube, fiber optic, color TV, remote controls, and satellites are only a few of the technological advances that have transformed television over the years. During the last decade, the audiovisual industry has not stopped innovating and creating numerous other tools of production and post-production for TV, movies, commercials, and other digital media. Host Nerdo Cavernas takes viewers on a journey to get to know all these important advances.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The spaceship lands on a planet where a robot is expecting them. His only interest is in Maqui. The robot shows her around the planet and reveals some of the planet’s objects. He shows her ships, satellites, and other space objects that were launched from planet Earth.
Episode one explores what hurricanes are, how they are formed, and how the specialists try to predict whether the next storm will blow over or blow the roof off. Featuring interviews with some of the world’s leading hurricane experts, this episode looks at the latest theories and the most advanced technologies that are being used to hone the forecasts. While a fearless team of Hurricane Hunter pilots flies into the eye of each approaching storm, their data is supplemented by information from satellites, drones, and even fish. Part of "Hurricane, the Anatomy" series.
Space weather can have important consequences for everyday life, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation. The United States Geological Survey (USGS) Geomagnetism Program monitors variations in the Earth's magnetic field through a network of 14 ground-based observatories around the United States and its territories, providing data in real-time to a variety of customers.
Visionary oceanographer Scott Glenn leads a team of scientists as they race against time to launch the first autonomous underwater robot across the vast and dangerous Atlantic Ocean. Destined for Spain, the 8-foot bright yellow robot named RU27, or "Scarlet," is launched off the coast of New Jersey. Throughout her journey, data collected by Scarlet is fed into oceanographic navigation and forecasting models. Engulfed by the powerful ocean, our robot hero faces extreme weather conditions, ship traffic, and aggressive sea life that can terminate her mission. If Scarlet can successfully cross the vast Atlantic Ocean, her historic mission will inspire a future robotic oceanographic observation network critical for monitoring and predicting climate change.
