❄️ When you hear "Snow Day," do you think of sledding and hot cocoa? For our scientists, a snow day can be the perfect day for work! (Along with sledding...) In fact, a snow day is crucial for our researchers who gather data from the icy parts of our planet. ❄️

Don’t get dizzy 😵‍💫 This Iceberg, named A-84, has been ricocheting off parts of the Antarctic coastline over the past month. It has drifted about 250 kilometers (150 miles) from its point of origin. go.nasa.gov/4bth3DR

In September 2018, ICESat-2 fired its laser instrument for the first time. In the next few days, it will fire for the 2 trillionth time. While we wait to see what that shot will measure (Ice? Ocean? Clouds?), take a look back at those first photons. nasa.gov/science-resear…

Happy 2,000,000,000,000th, #ICESat2! 💚 🛰️ 🎉 You don't look a laser pulse over 1.9 trillion. NASA’s Earth-observing laser in orbit passed a milestone March 9, as it fired for the 2 trillionth time, measuring clouds off the coast of East Antarctica. blogs.nasa.gov/icesat2/2025/0…

Join us for a NASA ICESat-2 data training webinar titled "Laser Altimetry Applications for a Changing World: Working with ICESat-2 Bathymetry Data" on Wednesday, April 9 at 2:00 p.m. EDT (-04:00 UTC).

How do you use #ICESat2? This week, we’re meeting people who use NASA’s height-measuring satellite in creative ways to answer questions about our home planet. First up, mapping coastal seafloors from space. Full video: youtube.com/watch?v=379SrQ…

How do you use #ICESat2? If you're interested in using lidar data to peer through coastal waters, tune into a NASAEarthdata webinar on the mission's new bathymetry data product. 🛰️🌊📉

How do you use #ICESat2? For this team of archaeologists, the satellite's precise data on sea level helps them study lost civilizations. Full video here: youtube.com/watch?v=d6c8P5…

How do you use #ICESat2? Some scientists are tapping into ICESat-2’s precise elevation data to monitor the ups and downs of water levels in reservoirs and lakes. Meet one who combines ICESat-2 and other data to study global water storage. Full video: youtube.com/watch?v=Zz3gW9…

How do you use #ICESat2? One team puts the satellite's data to work validating the models used to generate coastal elevation maps, which are important for warning of hazards like tsunamis and storm surges. Full video: youtube.com/watch?v=CiXNIW…

It's almost Earth Day. Let’s celebrate our home planet from a unique viewpoint – space! Use our “Your Name in ARCHIVED - NASA Landsat” app to spell out your name (or a pet, family member, or significant other’s name) with Earth features seen by satellite: go.nasa.gov/4jETaMq

Celebrate our home planet - including its icy rivers, deltas, Antarctic islands, and glaciers - with NASA this #EarthDay! Write your name in ARCHIVED - NASA Landsat images here: go.nasa.gov/4jETaMq

Did you celebrate Arbor Day Friday? #ICESat2 celebrates - and measures - trees all year long! The mission's global height data can monitor the height & health of forests around the world. Want to help? You can NASA Citizen Science and observe tree heights with the The GLOBE Program.

Cryo2ice is heading back to the Arctic! 🛰️🐻‍❄️🛰️ It’s a great opportunity. Earlier this year ESA Earth Observation CryoSat and NASA Ice ICESat-2 measurements became so closely spatiotemporally collocated that Cryo2ice observations are currently quasi-simultaneous. 🔗earth.esa.int/eogateway/news…

An update: We're consolidating social media accounts later this month and will no longer be posting here. Be sure to follow NASA Earth for the latest on NASA missions, research, and fieldwork that explores the frozen reaches of our home planet. 🧊 🛰️ ❄️ 📷: NASA/K. Mersmann

Many of you tuned in here for images of the far-flung fieldwork NASA scientists do in our planet's frozen realms. As we consolidate with NASA Earth, share your favorite cool pic of glaciers, permafrost, sea ice, or an icy backyard pond. 📷: NASA/Maria José Viñas

Better together 🤝 NASA’s ICESat-2 satellite and GEDI instrument on the International Space Station work together to give us the most complete view yet of Earth’s forests! They each map forests in 3D, helping scientists understand the carbon stored within our forests.
