How do astronaut spacewalk?

On 20 July 2019, ESA astronaut Luca Parmitano was launched to the International Space Station from the Baikonur Cosmodrome in Kazakhstan. During the Beyond mission he will participate in several spacewalks (EVA) to repair the dark matter hunter Alpha Magnetic Spectrometer, or AMS-02. Attached to the station during the STS-134 shuttle mission in May 2011, the AMS was never designed to be maintained in orbit. Luca has trained extensively for this challenging task, which will involve complicated techniques and the use of specially-designed tools.
