Coverage of U.S. Spacewalk 83 to Install the ISS Roll Out Solar Array on the Port 4 Truss to Augment Electrical Capability for the 4A Power Channel (Rubio and Cassada; spacewalk is scheduled to begin at approximately 8:30 a.m. EST and will last around 7 hours) – Johnson Space Center (All Channels).

Quote from: Rob Navias - Email (11/24/2022) to "Ben E"
Q: Have EVA crew members been identified yet for U.S. EVA-82 and 83?
A: Cassada and Rubio for the next two

Q: I understand from NASA's TV schedule that the iROSA EVAs have now moved to 3 Dec and NET 19 Dec...
A: We had to wait for the end of a beta angle cutout

Q: Many thanks. Can I also just check: is Cassada still EV1 and Rubio EV2, or will they swap?
A: Cass is EV1 and Rubio is EV2 for the next one and the swap designations for the one after that

Looks like this EVA is also going to be delayed to freed up the SSRMS for Soyuz MS-22 exterior inspections.

MCC-H confirmed during Friday evening DPC that the EVA Monday is postponed while program analyzes the Soyuz leak.  The plan for Sunday is being reworked to reflect the postponement.

MEDIA ADVISORY M22-185
NASA to Air Live Coverage of US Spacewalk for Solar Array Installation

NASA astronauts aboard the International Space Station will conduct a spacewalk on Wednesday, Dec. 21, to install a rollout solar array to increase electrical power in support of operations and scientific research. The spacewalk is scheduled to begin at 7:45 a.m. EST and last about seven hours.

The agency will provide live coverage of the spacewalk beginning at 6:30 a.m. on NASA Television, the app, and the agency’s website.

Expedition 68 Flight Engineers Frank Rubio and Josh Cassada will exit the station’s Quest airlock to install an International Space Station Roll-Out Solar Array (iROSA) to augment power generation for the 4A power channel on the station’s port truss.

Rubio will serve as extravehicular crew member 1 (EV 1) and will wear a suit with red stripes. Cassada will serve as extravehicular crew member 2 (EV 2) and will wear an unmarked suit. The spacewalk will be the third in both Cassada and Rubio’s careers.

If more time is needed to complete the iROSA installation, a second spacewalk may be conducted on Tuesday, Dec. 27.

This will be the fourth iROSA installed on station out of a total six planned for installation. Overall, the iROSAs will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.

The iROSA arrived at the space station Nov. 27, following a launch aboard the agency’s 26th SpaceX Dragon commercial resupply mission Nov. 26.

Cassada and Rubio are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including NASA’s Artemis missions to the Moon.

Late Orbital debris conjunction caused the scrub, PDAM using Progress planning in progress.  Debris part of a Russian Fregat upper stage that is apparently rarely tracked--in a high inclination/Molniya orbit?
