What Does EVCU Stand For?

EVCU stands for Extravehicular Communications Umbilical

EVCU, or Extravehicular Communications Umbilical, is a critical system designed to provide continuous communication between astronauts conducting extravehicular activities (EVAs) and their support teams on the spacecraft or mission control. This umbilical connection ensures a reliable flow of voice and data communication, allowing for real-time collaboration, safety monitoring, and mission support during spacewalks. The EVCU enhances operational efficiency and astronaut safety by maintaining essential communication links in the challenging environment of space.
