NOAA's environmental satellites provide data from space to monitor Earth to analyze coastal waters, relay life-saving emergency beacons, and predict and track tropical storms and hurricanes. NOAA operates three types of satellite systems for the United States: polar-orbiting satellites, geostationary satellites, and deep space satellites. Polar-orbiting satellites circle Earth and provide global information from 540 miles above Earth. Geostationary satellites constantly monitor the Western Hemisphere from around 22,240 miles above Earth. The deep space satellites orbit one million miles from Earth, providing space weather alerts and forecasts while also monitoring the amounts of solar energy absorbed by Earth every day.

Offers a look at what kind of information satellites provide about our world. Satellite imagery has multiple uses: showing crops and pests, monitoring weather in all its forms, following forest fires and air pollutants, and more. Imagery notes climate changes, the ozone layer, and temperature of many things--all designed to predict and protect. These sensors present unusual windows to our world.
While Earth's weather reports center on precipitation, temperature, wind direction, and humidity, space weather forecasts attempt to predict activity that occurs on the sun. Scientists also study how the weather on the sun will affect Earth. At the University of Michigan a team studies solar storms as they form and then barrel off the sun. Sometimes these storms hit the Earth with damaging force. Space weather has the potential to interfere with everything from satellite communications to electrical power. This team is aiming for a five-day forecast capability to give government, private industry, satellite operators, and power grid companies more time to take necessary action to protect critical infrastructure.

The inventions of the 1960s were all about transforming science fiction into fact. Robots, satellites and a trip to the moon help make what was once only fantasy, become a reality. Featured inventions include: the Lunar Lander, weather satellites, video game consoles, Tasers, and industrial robots.
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 three friends arrive at a planet surrounded by space debris. Maqui tells them that this debris may come from remains of spaceships or useless artificial satellites. The kids learn the difference between natural satellites and artificial satellites.
Using crisp images and lifelike animations, this program introduces students to the intriguing realm of stars and galaxies. The main characteristics of galaxies and stars are discussed. Special attention is given to the features of stars, including size, temperature, and brightness. The life cycle of a star is also highlighted, as are the tools used by astronomers to study space. Additional concepts and terminology illustrated in the video include: universe, telescope, satellites, constellations, star color, spectrum, gas, light-year, and black hole.
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.
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.
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.
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.
Researchers from NOAA's National Marine Mammal Lab track the migrating fur seals to understand where they feed in winter months and what marine resources they depend on for survival. It's early November and the team affixes a satellite transmitter to an adult female. They won't see her back on the Pribilof Islands until next July, and they hope the tag will stay on throughout winter and spring. Back at their offices in Seattle, the researchers begin tracking tagged animals via satellites.
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.
With the retirement of NASAs 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 to the increasing market of suborbital spaceflight and the possibility of private citizens utilizing space flight. Students will explore suborbital and orbital spaceflight and the requirements necessary for vehicles to achieve these journeys. They also go behind the scenes of many of the private companies involved in taking on the tasks to travel to low Earth orbit and beyond and uncover some of the technology used to accomplish these goals.
