DSN Uplink - Downlink

In this game you’ll use these big antennas to send information to — and receive information from — NASA’s robotic explorers in the solar system and beyond. Scientists call this process “uplinking” and “downlinking.” An antenna "uplinks" instructions to a spacecraft and "downlinks" the spacecraft's data and images back to Earth.
