    Planning to watch ? If 🛰 flew directly over a football 🏈 field, it would collect 130 measurements between each end zone.

    Go long! We’re gearing up to watch some phootball, err…football 🏈...with an extra special edition of . In April, 🛰 passed over Miami, where will be played this weekend.

    What’s a satellite scientist doing on polar bear watch? This fall, ’s Nathan Kurtz joined the expedition on a research vessel intentionally frozen into the Arctic ice. It was an isolated, alien landscape, he says– and home turf for polar bears.

    Five new field campaigns ✈️ are taking off this year, around the U.S., to study everything from snowstorms ❄️ to sea level rise 🌊. In one hour, will be live with pilots and researchers as they prepare to study our home planet.

    The coolest thing about spending New Year's Day at the South Pole? The Jan. 1 ceremony to place a marker on the geographic South Pole - exactly 90°S 🇦🇶 (Last year's marker? It shifted a bit, along with the Antarctic ice sheet)

    As they prepared for a 3rd expedition to collect Antarctic elevation data, scientists spent Christmas at the South Pole!🎄💈 Two team members even ran a Race Around the World: a 2-mile course crossing each line of longitude🌐

    How are glaciers in the Pacific Northwest changing? With a pass right over Mt Baker and Mt Adams, could help us find out! Ben Smith explains in today’s ... the phinal weekly installment of our look at how ICESat-2 🛰 measures our home planet 🌎

    ICESat-2 doesn't just measure peaks and valleys over land and ice - Lori Magruder presented work from Brad Klotz, showing the satellite's measurements of wave heights in the open ocean.

    As ICESat-2 takes measurements over the sea ice, it's important for the satellite to distinguish these melt ponds from the open water between floes- so Marco Bagnardi is working on tools to do just that.

    ICESat-2, often in combination with CryoSat-2, can help answer a number of questions about sea ice, said Sinead Farrell - including snow cover, ice thickness, and the size of melt ponds, some of which hold more than 3.5 Olympic🏊‍♀️ pools worth of water

    In the polar ocean, sea ice isn't one continuous sheet - it's lots of smaller pieces mashed up together, said Thomas Armitage. He's developing methods to identify the gaps between those pieces, and determine the size of these floes.

    ICESat-2 is the latest laser altimeter to take the measure of Greenland's glaciers, and Beata Csatho is adding this new set of measurements to the record to look at how places like Jakobshavn Glacier have changed since the late 1990s

    Glaciers might make up less than 1% of land ice on Earth, but they have an oversize impact on sea level rise - and Alex Gardner is studying how they have changed in the years between ICESat and ICESat-2.

    With 1,056 missions over Earth's polar ice, Operation not only bridged the gap in data between ICESat and -2, it completely revamped our view of our planet's frozen regions.

    There's a ton of amazing ICESat-2 data- from information on each individual photon return, to data products for things like land ice, sea ice and vegetation, reports Kaitlin Harbeck. And it's all available free to the public at .
