description
Explore the world of satellites using hands-on experiments to understand the technology satellites employ and the data they provide. Travel through orbital paths with JPL's Eyes on Earth 3D technology. Use GPS to identify pixels and learn how to analyze images and design your own 3D images with ImageJ software.

Space ExplorationSatellites are our eyes and ears in space. Space
Exploration is not only accomplished by humans, but by machines as well. Since 1958 with the launch of Explorer I, NASA has launched hundreds of satellites to test weather, earth geographic changes, collect astronomical data, and much more. Satellites in the past have been as large as a bus. Now with new technologies NASA is moving to small nano satellites through the CubeSat initiative. Like human space travelers, these machines are explorers of our universe and beyond.
As a SEEC Earth Explorer you will..
• know what satellites are.• how they stay in orbit.• what data they provide.• how we use the data to
monitor our home planet.• how we interpret data.• how to create data of our
own. • HAVE FUN LEARNING!!
WHAT DO THESE TWO OBJECTS HAVE IN
COMMON?
International Space Station Earth’s Moon
Both are Earth’s Satellites!The Moon is a natural satellite and the ISS is a man-made satellite! Both have many similarities and differences. With all that in mind they are not going to orbit without the Earth’s strong force of gravity keeping them in a constant state of free fall.
How do satellites stay in space?Centripetal Force1. the force, acting upon a body moving along a curved path,
that is directed toward the center of curvature of the path and constrains the body to the path. dictionary.com
Feel the Force
Spinning Penny
Swinging Tray
Less than 2,000km/ 1200 mless than the distance from Houston to Salt Lake City
Satellites in Geosynchronous Orbit
Less than 40,000 km/ 24,000 m
Explore Satellites in real time as they gather data from Earth’s Atmosphere, Oceans and Land.MAKE YOUR OWN 3D GLASSES
GRACE
We can use the Force, now let’s explore Earth!
The Landsat Program launched in the early 70’s and has archived continuous images from then until now. This program has allowed scientists to study our earth and the changes it’s
surfaces goes through for nearly 40 years.
