Test ranges, observatories and ground stations are a hand-picked list kept in this project rather than a published catalogue: no catalogue answers which of the world's thousands of observing sites belong on a map of it. The article below is what lets the choice be argued with.

## What it is

The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications. The system was designed to replace an existing network of ground stations that had supported all of NASA's crewed flight missions.
