Acheron Atmosphere Processing Plant Sticker

The Atmosphere Processing Plant also known as the Atmosphere Processor is a large automated reactor capable of "converting" an unbreathable, toxic or otherwise inhospitable atmosphere into one suitable for human habitation. Atmosphere Processors are a key component of extrasolar colonization efforts. The technology was pioneered by Weyland Corp in the first half of the 21st century and was later developed and refined by the Weyland-Yutani Corporation. While the conversion process is entirely automated, a constant crew is required to oversee an APP's maintenance. Often an entire colony will be established for this very purpose, such as Hadley's Hope on Acheron (LV-426).
