ICESat-2 Elevates Our View of Earth

The video discusses Earth's visible features like oceans and forests, and the challenges in measuring elevation globally. It introduces ISAT-2, a mission designed to measure changes in the cryosphere, particularly in polar regions where mass loss occurs. The mission uses the Atlas instrument, which sends laser pulses to measure surface height with high precision. NASA developed new methods to measure time accurately, crucial for determining elevation changes. The video highlights the amplified effects of climate change in polar regions and ISAT-2's role in understanding these changes.
