transceivers here at home that let us communicate with them. The new “Uplink-Downlink” game on The Space Place is a fun way to see how it works. The spacecraft are so far away, they might as well be stationary in the sky as Earth turns below. Three different antennas (dish-type radio telescopes) of the Deep Space Network (DSN) pass by one at a time below as Earth turns. Your job in the game is to aim the moving antenna at a spacecraft, transmit a command, then receive 100% of the data sent back from as many as five spacecraft before the game is over.
