Capped tubes at AMS-02 worksite

Image of the Vertical Support Beam (VSB) worksite on the Alpha Magnetic Spectrometer AMS-02 taking during ESA astronaut Luca Parmitano's second spacewalk to service the International Space Station's cosmic ray detector.
Here, Luca cut tubes in preparation to install a new cooling system. He made them safe by capping them and will connect them to the instrument's new cooling system during the third spacewalk in the series.
