EVA-3 of Expedition 50 is complete

Today, Shane Kimbrough (USA) and Thomas Pesquet (France) ventured outside the ISS to complete the 40th spacewalk from the US segment of the International Space Station, and the 198th overall.  (Note: most of the ISS spacewalks were conducted not from Station at all but from Shuttle, which is why the total spacewalk number appears so inflated by comparison.)  Today’s activities revolved mostly around prepping PMA-3 for its upcoming move to the Harmony node, where it will become available for future commercial crew operations.  This mostly consisted of unplugging things.  They also installed a new multiplexer/demultiplexer (MDM), did some work on the external cameras, lubricated the SSRMS, and completed some inspection work.  This video covers the entire spacewalk, not just the highlights, so maybe flip around through it to find interesting bits.  😉  This includes egress; you have to go up to about 45 minutes before they’re even emerging from the airlock.  (Spacewalks are complex; it’s not like going for a casual stroll.)
