US EVA 86 - Apr 28, 2023 (Al Neyadi, Bowen)
« on: 04/06/2023 10:31 pm »
There have been frequent "return" (ground to ISS) Ku outages in recent weeks.  These outages are preventing use of audio channels SG-3/4 which are often used for scientific experiments but with the outages, ground support cannot speak to the crew. Pending confirmation, my guess is replacement of faulty Ku compenent(s)...

MEDIA ADVISORY M23-044
NASA Sets Coverage of Spacewalk, News Conference for Station Upgrades

Two crew members, including a NASA astronaut, living aboard the International Space Station will conduct a spacewalk Friday, April 28, to continue installation of hardware to support future power system upgrades. Agency experts will preview the spacewalk during a live news conference at 2 p.m. EDT on Monday, April 24, from NASA’s Johnson Space Center in Houston.

Live coverage of the news conference and spacewalk will air on NASA Television, NASA app, and on the agency’s website at:

https://www.nasa.gov/live

The news conference will take place with the following participants:

    Dina Contella, operations integration manager, International Space Station Program
    Scott Stover, spacewalk flight director
    Sandra Fletcher, spacewalk officer

The agency will provide live coverage of the spacewalk beginning at 7:45 a.m., Friday, April 28. The spacewalk is scheduled to begin at about 9:15 a.m., and last about 6.5 hours.

NASA astronaut Steve Bowen and UAE (United Arab Emirates) astronaut Sultan Alneyadi will exit the station’s Quest airlock to prepare for future installation of upgraded solar arrays on the starboard side of the station’s truss. The astronauts will then retrieve S-band antenna equipment and bring it inside the space station for refurbishment.

The spacewalk is part of a series to augment the station’s power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four of the new arrays have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks following their arrival this year on SpaceX’s 28th commercial resupply services mission for NASA.

Bowen will serve as extravehicular crew member 1 (EV 1) and will wear a suit with red stripes. Alneyadi will serve as extravehicular crew member 2 (EV 2) and will wear an unmarked suit. U.S. spacewalk 86 will be the eighth spacewalk for Bowen and the first for any UAE astronaut.

I'm confused. How did the SASA end up on ESP-2?  I though the failed P1 SASA was sent to ELC3 at the end of EVA-78.
Am I wrong, or is this a different SASA, or did it get moved later?

The writeup's kind of vague, but I did find the following in the 14 November 2022 ISS Daily Summary Report:

Quote
Robotic Operations: Due to an issue last Thursday, the ground teams deferred the scheduled Remote Power Controller Module (RPCM) remove and replace (R&R). On Saturday, the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) were maneuvered to the Express Logistics Carrier-3 (ELC-3), where the SPDM grasped and unstowed the spare SASA Flight Releasable Attachment Mechanism (FRAM). The SSRMS and SPDM were then maneuvered early Sunday morning to remove the degraded SASA FRAM and replace it with the spare one. After the degraded SASA FRAM was stowed, the Mobile Transporter (MT) was translated from Worksite 7 (WS7) to WS5 where the SSRMS then stowed the SPDM on LAB PDGF 2. The MT was translated from WS5 to WS2, and the SSRMS was maneuvered to the viewing position for the 1B IROSA Prep EVA.

Edit - the other thing that might help pin down the timing of the move - the last ORU to be in that spot on ESP-2 was a Latching End Effector, which some spacewalk imagery definitely places there in March 2022. So if anyone heard about an LEE move within the last year, that would also give us some pointers.

I went digging a little more to try to figure out when the SASA was moved to that spot on ESP-2. On the last USOS EVA, we got this view from Koichi Wakata's helmet cam that shows ESP-2 pretty clearly. The FRAM in question is the one on the lower side, outboard (to the right in this image), further from Koichi. I think, based on the animation for EVA-86, that that ORU is too big to be the SASA, and is probably still the LEE. Backing this up, the DOUG animation for EVA-85 definitely shows the LEE in that position.

So my new guess, until/unless we get a #askNASA answer during the webcast, is that it was swapped at some time since 2 February 2023.

The Exp 69 crew is GO for Friday's spacewalk set to begin at 9:15am ET live on @NASA TV. Health checks and robotics tests rounded out the day's schedule.

The Expedition 69 crew is ready for a spacewalk set to begin on Friday to upgrade the International Space Station’s power generation system. In the meantime, fitness evaluations and robotic tests rounded out the schedule aboard the orbital outpost on Thursday.

Flight Engineers Stephen Bowen of NASA and Sultan Alneyadi of UAE (United Arab Emirates) are finalizing their tool collections and Quest airlock configurations the day before their six-and-a-half hour spacewalk begins. They staged their Extravehicular Mobility Units (EMUs), or spacesuits, inside Quest and finished studying the procedures they will use to route power cables and retrieve an antenna on the station’s starboard truss structure. The external hardware work will ready the space station for its next set of roll-out solar arrays due to be installed after their delivery on the next SpaceX Dragon cargo mission.

Bowen and Alneyadi will set their EMUs to battery power at around 9:15 am. EDT on Friday signifying the beginning of their spacewalk. This will be Bowen’s eighth career spacewalk, Alneyadi’s first, and the fourth of 2023. NASA TV, on the agency’s app and website, will begin its live spacewalk coverage 7:45 a.m.

NASA Flight Engineers Frank Rubio and Woody Hoburg participated in today’s final spacewalk preparations joining the spacewalkers for a procedures review, tool checks, and a conference with engineers on the ground. Rubio and Hoburg, on Friday, will assist the spacewalkers in and out of their spacesuits, maneuver the Canadarm2 robotic arm, and monitor the activities.

Two cosmonauts took turns pedaling on an exercise cycle for a fitness evaluation on Thursday morning. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin attached sensors to themselves measuring their heart activity and blood pressure then exercised for about an hour. The fitness study ensures the pair is in good shape ahead of a spacewalk planned to start at 4:05 p.m. EDT on Wednesday, May 3. Prokopyev and Petelin will exit the station in their Orlan spacesuits and spend about six hours moving an experiment airlock from the Rassvet module to the Nauka science module.

Roscosmos Flight Engineer Andrey Fedyaev spent his day inside the Nauka module testing operations with the European robotic arm (ERA). He practiced grappling the experiment airlock and maneuvering techniques with the ERA, the same maneuvers he will use to assist the Roscosmos spacewalkers during next week’s logistics spacewalk.

Th Youtube channel normally only airs SG-2 which is the usual US audio channel but EVAs are done on SG-1 so we may not hear much until NASA TV coverage starts..
