Q: Have EVA crew members been identified yet for U.S. EVA-82 and 83?A: Cassada and Rubio for the next twoQ: 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 cutoutQ: 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

miss distance within 1/4 mile. Maneuver target 0742 central, 0842 eastern.
This appears to be object nr 52960, 2011-037PP, a piece of debris from the Fregat stage of the Spectr-R launch
Encounter with the Fregat debris would have been over the Pacific Ocean near 18.5 N 168.4 E near 16:17:43 UTC (21 Dec) :
Space Station Maneuvers to Avoid Debris After Conjunction Postpones SpacewalkThe International Space Station conducted a Pre-Determined Debris Avoidance Maneuver (PDAM) today, Dec. 21, at 8:42 a.m. EST. The decision to conduct the maneuver was based on tracking data that showed a close approach to station of a fragment of Russian Fregat-SB upper stage debris.During the manuever, the Roscosmos Progress 81 thrusters fired for 10 minutes, 21 seconds to provide the complex an extra measure of distance away from the predicted track of the debris. Without the maneuver, it was estimated that the debris could have passed less than a quarter of a mile from the station.The decision to conduct the maneuver earlier this morning resulted in a postponement of today’s planned spacewalk by NASA astronauts Frank Rubio and Josh Cassada. The crew was never in any immediate danger.Learn more about station activities by following the space station blog, @space_station and @ISS_Research on Twitter, as well as the ISS Facebook and ISS Instagram accounts.Get weekly video highlights at: https://roundupreads.jsc.nasa.gov/videoupdate/Get the latest from NASA delivered every week.

Quote from: Targeteer on 12/21/2022 10:33 ammiss distance within 1/4 mile. Maneuver target 0742 central, 0842 eastern.Wow, that's awfully close for a full Fregat if accurate, especially when it could have shed small pieces (insulation, paint flakes...) over time into similar orbits around it, which would be completely invisible being in a highly elliptical orbit.Orbital debris is giving ISS a hard time these last few days.
[email protected]_Astronauts Josh Cassada and Frank Rubio began their spacewalk today at 8:19am ET. They will install the fourth of six roll-out solar array panels that will increase station power generation capability by 30%.
About an hour into the spacewalk, Cassada is working to release the anti-rotation devices on the iROSA that are holding it in place. Rubio is securing power cables that will be connected once the iROSA is in place and making sure the soft-capture system is ready for its arrival.
Earth views as Rubio on the right and Cassada on the left are seen working together to release iROSA from it’s holding location so that they can relocate it for installation, with the @csa_asc #Canadarm2 seen above! 🔧🌍🦾
[email protected]_Josh and the 750-lb iROSA get a lift to the installation site from the Canadarm2 robotic arm, flown by @AstroDuke and @Astro_Wakata from inside the station. Rubio makes his way to the work site where he prepped the power connection cables earlier in the spacewalk.
Station is now in eclipse, and the astronauts are working to disconnect the cables to the legacy arrays / reconnect them to new Y-cables that will splice in the iROSAs.
What are the red and blue dots--bad camera pixels?

NASA Spacewalkers Install Station’s Fourth Roll-Out Solar ArrayExpedition 68 Flight Engineers Josh Cassada and Frank Rubio of NASA concluded their spacewalk at 3:27 p.m. EST after 7 hours and 8 minutes.Cassada and Rubio completed their major objectives for today to install an International Space Station Roll-Out Solar Array (iROSA) on the 4A power channel on the port truss. 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.It was the 257th spacewalk in support of space station assembly, upgrades, and maintenance, and was the third spacewalk for both astronauts.Cassada and Rubio are in the midst of a planned six-month 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 lunar missions through NASA’s Artemis program.While Thursday’s spacewalk was underway, NASA Space Station Program Manager Joel Montalbano and Roscosmos Human Spaceflight Executive Director Sergei Krikalev participated in an audio-only media teleconference. The two space executives discussed the ongoing investigation of an external leak detected on the Soyuz MS-22 crew ship. Ground teams continue to assess data and options for the safe return of crew to Earth.Listen to the teleconference here.A transcript of the telecon will be provided once available.
NASA spacewalker Josh Cassada prepares the station’s fourth roll-out solar array for its installation and deployment as the orbiting lab flew above the Atlantic Ocean off the coast of Namibia.
Not sure where the best place to put this.Per Rob Navias via emailThe iROSA FSE / carrier is not loaded / departing with CRS-26.It will instead be jettisoned via the SSRMSMy best guess is that the MS-22 inspection occupied a lot of arm time and there was not enough time to load the FSE / carrier back into dragon
