  • New mission to track changes in the cryosphere

    New mission to track changes in the cryosphere

    Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Monitoring the cryosphere is crucial for assessing, predicting and adapting to climate change.

    The Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL) mission will provide a full picture of the changes taking place in some of the most inhospitable regions of the world. It will carry – for the first time – a dual-frequency radar altimeter, and microwave radiometer, that will measure and monitor sea-ice thickness, overlying snow depth and ice-sheet elevations.

    These data will support maritime operations in the polar oceans and contribute to a better understanding of climate processes. CRISTAL will also support applications related to coastal and inland waters, as well as providing observations of ocean topography.

    CRISTAL is one of six Copernicus Sentinel Expansion missions that ESA is developing on behalf of the EU. The missions will expand the current capabilities of the Copernicus Space Component – the world’s biggest supplier of Earth observation data.

    This video features interviews with Kristof Gantois, CRISTAL Project Manager and Paolo Cipollini, CRISTAL Mission Scientist.

  • Ice coverage – the global thaw

    Ice coverage – the global thaw

    One of the causalities of climate change is the diminishing ice cover, affecting our planet in a number of ways. Our satellites observe the planet’s cryosphere and provide key information to understand and respond to global thawing.

  • NASA Explorers: Final Approach

    NASA Explorers: Final Approach

    In the pre-dawn hours of a late October day, a satellite and an airplane joined forces over the frigid Weddell Sea, taking simultaneous measurements of drifting sea ice. It was the culmination of more than a decade of planning, designing and building the best way to measure Earth’s changing ice.

    #NASAExplorers are constantly pushing the limit to learn more about our world and those far beyond. Join in as they celebrate a milestone in the quest to better understand the planet we call home.

  • NASA Explorers: The Launch

    NASA Explorers: The Launch

    It’s 5 a.m. on a normal September day and #NASAExplorers have gathered in a California field to watch a rocket launch light up the pre-dawn sky. On board the rocket is a satellite more than 10 years in the making, with one single instrument that will revolutionize the study of ice on Earth. Join the team in the excitement and stress of watching ICESat-2 launch into space and begin its work measuring our home planet.

  • NASA Explorers: Glacial Pace

    NASA Explorers: Glacial Pace

    #NASAExplorers study Earth’s glaciers and ice sheets more than almost any other part of the cryosphere. As they melt and change, glaciers and ice sheets dramatically affect sea level rise and the climate system as a whole, creating an urgency to understand and forecast their behavior.

    NASA Explorers: Cryosphere – The Big Thaw

    NASA Explorers is a new digital series that takes you inside the space agency and follows the pioneers, risk-takers and experts at the front line of exploration. Season 1, “Cryosphere,” joins NASA scientists on their journey to the frozen ends of the Earth as they study our rapidly changing world from satellites, planes and boots on the ground. The Cryosphere is a place we all depend on, but many of us will never go to. As temperatures rise, the frozen regions of Earth are changing rapidly. NASA scientists are locked in a race against time to understand our shifting climate and how it affects life on Earth.
