This
animation shows how WISE will communicate with the ground
when it is not within the horizon of a ground station.
NASA has a constellation of communications satellites orbiting
Earth called TDRSS. When WISE is not in direct contact
with a ground station it can communicate with one of the
TDRSS satellites that is within its view, then the TDRSS
satellite will convey the signal down to Earth, directly
or through another TDRSS satellite.
