Students build their own satellite using household materials. Through the process, they learn about satellites and their functions.
Video presents a broad overview of what (NASA) satellites can tell us about how climate change is affecting oceans.
This video segment adapted from NASA's Goddard Space Flight Center shows how integral satellites are to everyday life and describes the different types, including orbital and geostationary.
This site presents challenges faced by NASA engineers who are developing the next generation of aerospace vehicles. The challenges: thermal protection systems, spacecraft structures, electrodynamic propulsion systems, propellers, and personal satellite assistants. Students design, build, test, re-design, and re-build models that meet specified design criteria, using the same analytical skills as engineers.
In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and scientific concepts to create a standard for locating people and objects. This activity helps students understand both the need for and methods of navigation.
Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The sea-floor is characterized using underwater sound and acoustical systems. Current technological innovations are allowing scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles allows scientists to map and understand the sea floor, and in some cases, the water column. In this lesson, the students will be shown benthic habitat images produced by GIS. These imaged will lead to a class discussion on why habitat mapping is useful and how current technology works to make bathymetry mapping possible. The teacher will then ask inquiry-based questions to have students brainstorm about the importance of bathymetry mapping.
Students learn more about forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects.
From this original story, young readers and listeners learn about four tools scientists use to study climate - climate stations, weather balloons, satellites, and buoys. The story is available at two reading levels and in three formats - text-only, illustrated booklet, and electronic book. Glossary included. Each issue of Beyond Weather and the Water Cycle contains an original story that expands on the theme.
Benjamin Franklin is credited with saying, “Some people are weatherwise, but most are otherwise.” Ol’ Ben understood that weather can have a great effect on our everyday lives, and he knew the importance of having an understanding of what makes the atmosphere work (and not just knowing when it’s safe to fly a kite). In Meteo 3, we will examine all aspects of the weather. You’ll learn the fundamental processes that drive the atmosphere, along with some of the tools we use to measure those processes. You’ll also learn about large-scale weather systems, severe convection, tropical weather, and climate change. As a result, you’ll be a better consumer of weather information and forecasts. So… do you want to be weatherwise?
Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. In accompanying activities, they explore how ground-based tracking and onboard measurements are performed. Also provided is an overview of orbits and spacecraft trajectories from Earth to other planets, and how spacecraft are tracked from the ground using the Deep Space Network (DSN). DSN measurements are the primary means for navigating unmanned vehicles in space. Onboard spacecraft instruments might include optical sensors and an inertial measurement unit (IMU).
Learn Motion of Earth, Sun, Moon & Satellites in Orbit : Astronomical Time Standards and Time Conversions, Positional Astronomy - earth orbit around sun, Position of Sun on Celestial Sphere, Position of Earth on Celestial Sphere, Satellites Orbit Elements - ephemeris, keplerian elements, state vectors, Satellites Motion around Earth - orbital & positional parameters, Satellite Pass for Earth Station - prediction of ground trace are addressed.
This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they explore the "mind-boggling mysteries" of our solar system. The article opens with a quick review of what we know about our solar system and how we've gathered that information. Students then "explore the mystery" of each planet within our solar system, which is presented though fun facts, evidence, theories, and NASA missions. The article ends with a nine-question quiz that gives students a fun way to test what they've learned.
2010 marks the 400th anniversary of Galileo's astonishing sightings of features on the moon, stars, and moons around Jupiter that no one had seen before. Recreate these new ways of seeing and exploring from the materials and techniques Galileo had on hand, while you reflect on the times and works of Galileo. What was it like to improvise new ways of seeing and exploring from the materials and techniques on hand? What do we notice? What surprises us? How can we relate to past experience and ideas? What are we curious to research? How does our experimenting grow into our learning? Let your own curiosity drive your explorations.
Remote Sensing is the gathering of data remotely. This data is gathered from satellites, airplanes, and even drones flying through hurricanes.
Satellite Engineering introduces students to subsystem design in engineering spacecraft. The course presents characteristic subsystems, such as power, structure, communication and control, and analyzes the engineering trades necessary to integrate subsystems successfully into a satellite. Discussions of spacecraft operating environment and orbital mechanics help students to understand the functional requirements and key design parameters for satellite systems.
This animation adapted from NASA shows the orbital paths of spacecraft in NASA's Earth Observing Fleet that are a source of wide-scale, primary research about Earth.
