Saturday’s spacewalk, which lasted five hours and 55 minutes, was the last in a four-part series to extend the life of the particle physics detector that was not designed to be maintained in space.

During the first three spacewalks Luca and Drew replaced the old cooling system with a new one using a tube-tying technique known as swaging that was quite the feat to perform in space gloves.

Once all fixed were addressed, Luca and Drew wrapped things up by installing a mud flap between the new pump and vertical support beam before removing a cover known as a shower cap to expose the new radiator system.

Five hours and two minutes into Saturday’s spacewalk, Luca broke the European record for the most time spent spacewalking. He has now clocked in 33 hours and nine minutes, beating previous record holder Swedish ESA astronaut Christer Fuglesang’s 31 hours and 54 minutes.
