Bandwidth Memes

The cosmic irony of space exploration! NASA's Voyager 2 mission to Neptune in 1989 used technology from the 1970s, including a primitive 0.64 megapixel camera, to capture our best images of the ice giant. The 2.7 KB/s data transfer rate meant each image took HOURS to download—slower than the first dial-up modems! Meanwhile, your phone probably has a 12+ megapixel camera that instantly uploads selfies. Next time your WiFi buffers for 5 seconds, remember astronomers waited patiently while blurry Neptune pics trickled back at speeds that would make a snail seem zippy. Space: where cutting-edge science meets Stone Age bandwidth.
