The first spacewalk was conducted on November 15, 2019. The spacewalk began with the removal of the debris shield covering AMS and it was jettisoned to burn up in the atmosphere. The next task was the installation of three handrails in the vicinity of AMS to prepare for the next spacewalks and removed zip ties on the AMS' vertical support strut. This was followed by the "get ahead" tasks: Luca Parmitano removed the screws from a carbon-fibre cover under the insulation and passed the cover to Andrew Morgan to jettison. The spacewalkers also removed the vertical support beam cover. The duration of the spacewalk was 6 hours and 39 minutes.
