The one-way conversation where space talks and Earth just listens, fast.
means The transmission of data or signals from a satellite, spacecraft, or aircraft down to a ground station on Earth.
from A transparent compound of "down" plus "link," coined in the mid-20th century as space and satellite communications grew up — the natural counterpart to "uplink." "Link" here carries its old sense of a connecting element in a chain, from the Old Norse-rooted family of "hlenkr"; the directional "down" simply marks which way the signal is falling. A piece of clean engineering English, built for clarity rather than poetry.
