#NASA uses its #Telemetry and #Data Relay #Satellite System to maintain contact with its fleet of #spacecraft in #Earth #orbit.
#TDRSS allowed NASA to have constant communication with the Space Shuttle, and continues to provide service to the #ISS and #Hubble.
Even #McMurdo Station in #Antarctica can use it to communicate.
This #ULA #Atlas V #rocket is about to carry #TDRSK to orbit.
