NASA | Landsat Looks to the Moon
Every full moon, Landsat 8 turns its back on Earth. As the satellite's orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back around...

Landsat's Global View of Ice Velocity
Ice from glaciers constantly flows into the ocean, but the speed the ice moves at changes. Landsat 8 provides near-real-time mapping of ice speed in nearly all the world’s frozen regions. Information like ice speed helps scientists study...
