Todays spacewalk is cancelled due to an issue with one of the spacesuits. The #EuropeanRoboticArm, almost fully stretched, autonomously grappled a large radiator earlier is now going back to its home position on the #Nauka module.
Nauka commissioning threads meta commentaryMy rational for removing of # elapsed spacewalks and total # of spacewalks for Nauka commissioning from the title are:1. Our current numbering scheme on the forum is incorrect.VKD-49 - 1/10...VKD-53 - 5/10We lost sync on the following threads (with myself inadvertently contributing to the error)VKD-ESA RS EVA (5/10 Nauka&ERA ops): 21 July 2022 [Artemyev, Cristoforetti] - This should have been 6/10VKD-54 RS EVA (6/10 Nauka outfitting): August 17, 2022 [Artemyev, Matveev] - This should have been 7/10VKD-54A RS EVA (7/1? Nauka outfitting): September 2, 2022 [Artemyev, Matveev] - This should have been 8/11. (Corrected)VKD-55 RS EVA (8/13? Nauka outfitting): Nov 17, 2022 [Prokopiev, Petelin?] - This should have been 9/13. Where did 13 come from? (more on that later)2. The original estimate of 10-11 spacewalks is no longer valid. The most recent thread had listed 13 total spacewalks. However, the linked source for the increase in the total spacewalks stated 15 total spacewalks to complete commissioning.I feel that tracking progress via N of X number of spacewalks is not the most representative picture of the evolving commissioning process.
[/size]Not happening in a week's time, apparently:
Cosmonauts on #ISS are progressing with repairs of their Orlan suits aiming for the next spacewalk (VKD-56) as early as December 14 (if repairs are successful): russianspaceweb.com/iss-fgb2-mlm-i
Russian mission control confirms the VKD-56 spacewalk on December 14 aboard ISS, after cosmonauts had successfully repaired their spacesuits: russianspaceweb.com
This is not officially announced yet...
Spacesuits repaired, and the #EuropeanRoboticArm is ready to work again outside the @Space_Station installing a large radiator on the #Nauka module. 👨🚀🔧🦾🛰️The radiator mission will start on Wednesday 14 December (22h CET) and run the whole night until the morning (10h CET).
Can the #EuropeanRoboticArm operate in full sunlight? Yes, it can! 🤖😎🤓 Fun fact: the whole spacewalk and radiator mission will take place for 12 hours with no orbital nights. This is because the International @Space_Station is in a high beta angle until 18 December.
Last week, the cosmonauts on board of the ISS repaired the pumps in the cooling system of one of #OrlanMKS spacesuits (and, according to the rumors, replaced the pumps in the second one). The next attempt to perform #VKD56 will be on December 15, 02:20 - 09:20 UTC.

Busy bees for the #EuropeanRoboticArm 🦾Two spacewalkers will work tonight with @esa's space robot to install a radiator on the #Nauka module.The night will be long: the robot will start moving around the @Space_Station at 22h CET. Spacewalk coverage begins at 3 am on @NASA TV.
NASA TV coverage for cosmonauts Sergey Prokopyev and Dmitri Petelin's spacewalk outside the International Space Station begins at 9pm ET Dec. 14 (0200 UTC Dec. 15). Tune in at https://go.nasa.gov/3HyU4uk and follow @Space_Station for the latest updates.
Two cosmonauts are getting ready to exit the station for a six-hour and 40-minute spacewalk to move and install hardware live now on @NASA TV.https://blogs.nasa.gov/spacestation/2023/04/18/cosmonauts-getting-ready-for-spacewalk-live-on-nasa-tv/
Cosmonauts Getting Ready for Spacewalk Live on NASA TVNASA Television coverage is underway for todays spacewalk with Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The duo, with assistance from European robotic arm operator cosmonaut Andrey Fedyaev, will relocate a radiator from the Rassvet module to the Nauka science module on the International Space Station Coverage of the spacewalk is on NASA Television the NASA app, and agencys website.Prokopyev and Petelin will exit out of the Poisk module at about 9:30 p.m. EDT Prokopyev is wearing the Orlan spacesuit with red stripes, while Petelin is wearing the suit with blue stripes. This is the fourth spacewalk in Prokopyevs career, and the second for Petelin. It is the third spacewalk at the station in 2023 and the 260th spacewalk for space station assembly, maintenance, and upgrades.
NASA: VKD-56 start time is 9:40 p.m. EDT...
The @ESA robotic arm, operated by cosmonaut Andrey Fedyaev inside the station, moves the radiator from the Rassvet module to the Nauka module during today's spacewalk. nasa.gov/live
RS EVA-56: Poisk hatch closure confirmed at 5:35am EDT (0935 UTC); EVA duration was 7 hours and 55 minutes, pushing total ISS spacewalk time to 68 days 20 hours 23 minutes; Prokopyev's total through 4 EVAs is 29 hours and 51 minutes while Petelin's 2 EVAs total is 14:20
Cosmonauts Sergey Prokopyev and Dmitri Petelin completed a seven-hour and 55-minute spacewalk at 5:35am ET today after successfully installing a radiator on the Nauka science module.
The exit hatch is closed!Roscosmos cosmonauts Sergei Prokopyev and Dmitry Petelin spent 7 hours and 55 minutes overboard the ISS.During the release:▪️ the radiator on the Rassvet module was prepared for transfer;▪️ with the help of the ERA manipulator, the radiator was transferred to the "Science" module;▪️ an adapter for the ERA manipulator was installed on the airlock chamber at Rassvet;▪️ the radiator was docked to Nauka;▪️ An "Anchor" platform has been installed to fix the legs during the exit.Thank you for being with us! Stay tuned!
👨🚀 Russian crew members have started printing mock-ups of the ISS modules on a 3D printer in order to conduct spacewalk training, our special correspondent, Roscosmos cosmonaut Dmitry Petelin reports.Before practice, pilots sometimes work out a flight mission on the ground "on foot in flight" when they walk along the runway, imitating the trajectory and relative position of their aircraft with their models or palms. In the future, the astronauts plan to assemble a model of the entire station.Photo: Dmitry Petelin/Roscosmos/TASS, ISS
