International Space Station radiators

Image taken by ESA astronaut Luca Parmitano from outside the International Space Station on the second spacewalk to service the cosmic ray detecting Alpha Magnetic Spectrometer (AMS-02) on 22 November 2019.

The white panels that radiate heat are visible over Earth with the Station's 16-m robotic arm visible at the bottom of the image.

Due to the the AMS worksite being difficult to reach on top of the Station’s S3 Truss structure between a pair of solar arrays and radiators, Luca travelled to and from the site on the end of the robotic arm operated by NASA astronaut Jessica Meir from inside the Station.
