Image of the Week - RBV and Alaska Glaciers

Landsat sensor technology has come a long way since the days of the Return Beam Vidicon cameras on the first three Landsat satellites. Known as the RBV, it wasoriginally intended to be the satellites’ primary sensor. But the Multispectral

Scanner, or MSS, became the more stable and superior instrument.

Each week, the Earth Resources Observation and Science (EROS) Center highlights a new satellite image(s) featuring striking changes to the Earth's surface. Our images come from locations around the world.
