Topic No. 46: CETA Lights

CETA stands for "Crew and Equipment Translation Aid." These are special lights located on the exterior of the International Space Station (ISS).

These lights are used to provide illumination for astronauts working on the outside of the space station, especially during spacewalks (extravehicular activities) or when performing maintenance. They are attached to CETA carts, which are hand-pulled trolleys that help astronauts move along the station's main structure.

Key Points:

They are essential for providing light in the darkness of space.

They ensure the safety of astronauts during spacewalks.

They have built-in heaters to prevent their electronic components from freezing in the extreme cold of space.
