An earth orbit means that a satellite travels around the earth
and follows a special path while the earth rotates below it.
Most people when asked think that the LANDSAT circles the
earth around its middle - the Equator. However, in order to
take the pictures it does, it needs to fly around the earth from
pole to pole. That means it flies from around what we call the
North Pole down across the Equator to near the South Pole
and then back up the other side to near the North Pole and
then back down and up again.
This artist's drawing shows the LANDSAT
satellite taking images of the earth. This image is from the
LANDSAT Program home page
