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 @DoNASAScience and observe tree heights with the @GLOBEProgram.

Celebrate our home planet - including its icy rivers, deltas, Antarctic islands, and glaciers - with NASA this #EarthDay! .Write your name in @NASA_Landsat images here:

RT @NASA: It's almost Earth Day. Let’s celebrate our home planet from a unique viewpoint – space!. Use our “Your Name in @NASA_Landsat” app….

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:

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:

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:

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?.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:

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.

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.

RT @NASAEarth: Don’t get dizzy 😵‍💫. This Iceberg, named A-84, has been ricocheting off parts of the Antarctic coastline over the past month….

❄️ 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. ❄️

RT @NASAEarth: 2024 was the hottest year in NASA’s record. Global temperatures were around 1.28 degrees Celsius (2.30 degrees Fahrenheit)….

Can't wait 'til next September! 🗓️.NASA's 2025 Science Calendar features a spectacular photo of Arctic sea ice and melt ponds from an #ICESat2 airborne field campaign (.

RT @NASAEarth: Antarctic sea ice update 🌊🧊. Antarctic sea ice reached its max winter extent of 17.16 million sq km (6.62 million sq miles)….
