Zipping Up Data to Zap It Back from an Icy Moon

by Sarah Derouin 19 October 202219 October 2022

NASA wants to send instruments to distant moons like Europa and Enceladus to search for life. But getting vital data back to Earth over limited bandwidth will take some impressive compression software.

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.
