NASA’s Deep Space Network (DSN) is the giant planetary switchboard that helps dozens of distant spacecraft communicate with teams of engineers and scientists on Earth. The network of antennas and dishes relays messages from missions such as Voyager 1 and the Deep Space Climate Observatory (DSCOVR). The complex has several large radio antennas with parabolic dishes that appear as white circles in the Landsat image. NASA first established a DSN facility in Spain in 1964 as it was starting the Gemini and Mercury programs. The most powerful antenna at the Madrid facility is Deep Space Station 63.
