NASA to Preview Upcoming US Spacewalk, Provide Live Coverage
Two NASA astronauts are scheduled to venture outside the International Space Station for a six-and-a-half-hour spacewalks May 30. Experts from NASA will preview the work to be done during the spacewalk in a briefing at 2 p.m. EDT Tuesday, May 8, at NASA’s Johnson Space Center in Houston.
Expedition 55 Flight Engineers Drew Feusteland Ricky Arnoldwill put on spacesuits for what will be the 211th spacewalk in support of station assembly, maintenance and upgrades. This spacewalk will be the ninth of Feustel’s career, and the fifth of Arnold’s. The primary objectives are to finish upgrading cooling system hardware and install new and updated communications equipment for future dockings of commercial crew spacecraft.
Participating in the briefing are:
•Kenneth Todd, NASA’s International Space Station Operations integration manager
•Anthony Vareha, NASA spacewalk flight director
•Jordan Lindsey, U.S. spacewalk 50 officer at NASA
•Keith Johnson, U.S. spacewalk 51 officer at NASA
The second spacewalk is planned for Wednesday, May 30, but the exact timing is dependent on the anticipated May 24 arrival of the Orbital ATK Cygnus cargo resupply spacecraft. The ninth Cygnus cargo mission is scheduled to launch May 20 from NASA’s Wallops Flight Facility in Virginia.
During the May 30 spacewalk, Arnold and Feustel will install a pair of brackets and high-definition cameras on the Harmony module that will helpcommercialcrewvehicles align with the international docking adapterat the forward end of Harmony. The cameras also will provide wireless data network access for experiments and facilities mounted on the ESA (European Space Agency) Columbus laboratory and Japan Aerospace Exploration Agency Kibo laboratory. The crew also will replace a camera on the station’s starboard truss.

NASA TV to Air US Spacewalk at International Space Station
NASA astronauts will embark on a six-and-a-half-hour spacewalk Thursday, June 14, during which they will install new high-definition cameras to capture spacecraft docking with the International Space Station, including new American-made spacecraft with scheduled test flights later this year.
Live coverage of the planned spacewalk by American astronauts Drew Feustel and Ricky Arnold will begin at 6:30 a.m. EDT on NASA Television and the agency’s website.
Feustel, commander of the station’s Expedition 56, and flight engineer Arnold are scheduled to begin the spacewalk at 8:10 a.m.
The two spacewalkers will install brackets and high-definition cameras near an international docking adapter mated to the front end of the station’s Harmony module. The additions will provide enhanced views during the final phase of approach and docking of the SpaceX Crew Dragon and Boeing Starliner commercial crew spacecraft that will soon begin launching from American soil.
During their spacewalk, the astronauts also will swap out a camera assembly on the starboard truss of the station and close an aperture door on an external environmental imaging experiment outside the Japanese Kibo module. The imaging experiment hardware will be discarded on a future SpaceX cargo resupply mission.
The spacewalk will be the 211th in support of space station assembly and maintenance and the sixth station spacewalk this year. It also will be the ninth spacewalk in Feustel’s career and the fifth for Arnold. During the spacewalk, Arnold will wear a suit bearing red stripes while Feustel’s suit will have no stripes.
At five hours and 23 minutes into the spacewalk, Feustel will surpass NASA astronaut Peggy Whitson’s record of 60 hours and 21 minutes to move into third place for cumulative time spent during spacewalks.

-
-
Is the removal of MMOD shields a common task or do stubborn panels occur frequently?
More often these are recalcitrant bolts...
-
-
One more question. Are all operation-critical cables routed underneath the MMOD shields or is the risk of an impact on a cable too low compared to an entire module?
-
Back to MMOD...

What are the marks on the fabric cover
Scorching or some some of residue ?
Oxygen, some of which is lost whenever the hatch is opened, is converted to it's atomic constituent - O instead of O2. This is quite reactive, and reacts with the protective fabric.
As far as I remember, that is the cause.

Arnold posted some additional spacewalk pics on Twitter.
NASA-JSC also shared some pics on their Twitter account of Mission Control during the EVA.
