Singing the Icy Blues
Many of our favorite winter sports depend on snow. But did you know that snow helps fill lakes and form ice sheets and glaciers? Landsat helps scientists track the changes caused by warmer temperatures from beautiful blue lakes that supply water to vibrant aqua ponds that help glide glaciers to the sea.
Then & Now
Space can be a harsh environment, so Landsat satellites go through lots of testing before being launched.

The Columbia Glacier in Alaska is one of the most rapidly changing glaciers in the world. Exposed bedrock is brown, while rocky debris on the glacier’s surface is gray.

GLOBE Land Cover Challenge 2022
Nearly every aspect of our lives is fundamentally tied to the land on which we live. Documenting what is on the land (land cover) is important for many areas of critical science studied by NASA scientists. Scientists use Landsat to study Earth’s land surface, from the places people live to the most remote places on our planet. Find out how you can take part in the upcoming Land Cover Challenge: “Land Cover in a Changing Climate.”
Landsat Collage Challenge
Make your own art with Landsat images. Explore these stunning patterns and colors from folded red mountain ridges, yellow dunes dotted with brilliant pools of blue water, and swirling clouds of blue-green phytoplankton.
Data Viz
Ice sheets form in areas where snow that falls in winter does not melt entirely in the summer, building up over thousands of years. Try this activity to visualize the heights across the Greenland ice sheet using data from NASA’s ICESat-2 mission.

Postcard from Camp
This week we visit Norway’s ice-covered archipelago halfway between Norway’s mainland and the North Pole. Exceptionally warm air temperatures in summer 2022 have caused record melting across Svalbard. The abundant meltwater, much of which flowed to the ocean, is the latest expression of a rapidly warming climate.
EO Kids
EO Kids is discovering more about sea ice and its effect on ecosystems and global climate by looking at how and when it forms across the globe. Plus, learn how different types of water freeze in our “DIY Science” activity: “Saltwater is Cool.”
