Throughout their six hours and 7 minutes exterior, Cassidy misplaced a mirror from his spacesuit's left sleeve. He had no concept it had occurred and went about finishing his work - swapping out outdated batteries with new Lithium-ion batteries which are related to the ISS' photo voltaic arrays.

In line with a NASA weblog, their work can even embrace routing energy and ethernet cables in preparation for the set up of a brand new exterior wi-fi communications system with an enhanced HD digital camera and to extend helmet digital camera protection for future spacewalks. To assist future energy system upgrades, in addition they will take away a tool referred to as an “H-Fixture” that was put in earlier than the photo voltaic arrays had been launched to the area station
This spacewalk can also be purported to final from wherever round six to seven hours. NASA astronauts and SpaceX's Crew Dragon commander Doug Hurley together with Russian cosmonaut Ivan Vagner will assist Cassidy and Behnken throughout at the moment's stroll. This would be the eighth spacewalk for every astronaut.
Cassidy is already two-and-a-half months right into a six-month mission, alongside together with his two Russians counterparts - Anatoly Ivanishin and Vagner - who launched with him from Kazakhstan.
