Your Guides


Meet Paige and Pho - your guides through the ICESat-2 FunZone!
Join these two to learn more about the NASA ICESat-2 mission.

ICESat-2 uses green lasers, which are made up of bits of light called photons.

Hi, I'm Pho the Photon!

And I'm Paige the Penguin!

ICESat-2 is a satellite mission that will measure the height of Earth's ice-covered regions to track melting and other changes. From space, it will also measure the height of other features of our planet, including trees and shrubs, lakes and buildings.

Ice comes in many forms here on Earth, like mountain glaciers and frozen lakes, but most of it is found near the North Pole and South Pole. With temperatures on our planet warming up, many of these icy areas are melting.


Photon Jump

Pho, a plucky bright green photon of light, must travel from a NASA spacecraft down to Earth and back again to help complete a crucial science mission in this educational short film.

Real World: ICESat-2 and Earth's Cryosphere

Earth's cryosphere includes its frozen structures, such as sea ice, ice caps, and permafrost. Studying changes in the cryosphere provides scientists with valuable information about the past, present, and future of the planet. ICESat-2 will help scientists learn more about Earth's ice and its role in climate.

Our World: ICESat-2 - What Is Ice?

What is ice? NASA and ICESat-2 scientists explain the unique and essential qualities of frozen water. Water, unlike other types of matter, is less dense as a solid than as a liquid, allowing ice cubes -- as well as bigger chunks of ice -- to float on top of liquid water. Floating ice on lakes and oceans is important, allowing life to live in the water beneath it. Ice covered regions also have a big impact on our planet's climate and weather, even far away from the polar regions.

Our World: ICESat-2 Measures Ice Sheets

ICESat-2 allows NASA's scientists to make accurate maps of polar ice sheets, which helps improve predictions about weather patterns, climate change, and the effects of changing ice structures.

Launchpad: ICESat-2 - Next Generation Technology

Learn how ICESat-2 will be used to map the ice structures in the world's polar regions, allowing scientists to study changes on Earth.
