US EVA-78: For identification, Marshburn, call sign EV-1, is wearing a suit with red stripes and using helmetcam 22; Barron, EV-2, is wearing an unmarked suit with helmetcam 16; mission control CAPCOM today is astronaut Drew Morgan

Airlock pressure now <0.5 psi; hatch is open; standing by for the astronauts to switch their suits to battery power

Marshburn and Barron switched their suits to battery power at 6:15am EST (1115 UTC) to officially begin today's spacewalk; it's the 245th EVA in ISS history, the 13th so far this year, the 4th for Marshburn and the 1st for Barron

Marshburn and Barron are now out of the Quest airlock; after configuring tools and tethers, Barron will make her way to the ELC-3 platform where a spare S-band antenna is mounted while Marshburn heads for the P1 truss to attach a foot restraint on the lab's robot arm

(PET 1:30; 7:45am EST): Marshburn, on the end of the station's robot arm, has installed stabilizing gimbal locks on the failed S-band antenna unit; he and Barron are preparing to remove it from the P1 truss and move it to ELC-3

(PET 2:05; 8:20am EST): The failed S-band antenna is being temp stowed at the ELC-3 spare parts pallet; once secure, Marshburn and Barron will  remove the spare antenna, also on ELC-3, and carry it back to the P1 truss for installation

(PET 3:30; 9:45am EST): MCC-Houston says Marshburn and Barron are running about 90 minutes ahead of schedule; the new S-band antenna is now mounted on the P1 truss, gimbal locks are removed and wiring reconnected

(PET 3:43; 9:58am EST): Barron, inspecting the failed S-band antenna prior to permanently stowing it on ELC-3, says she's counted at least 11 small dings from presumed micrometeoroid impacts; such dings are fairly common on the station's exterior

(PET 4:22; 10:37am EST): The newly installed S-band antenna assembly has been powered up and verified working normally, able to receive and transmit voice and data; Barron is re-securing thermal insulation over the failed antenna, now mounted on ELC-3

(PET 4:40; 10:55am EST): With the antenna R & R complete well ahead of schedule, flight controllers may ask the Marshburn and Barron to carry out a few lower-priority "get-ahead" tasks before wrapping up today's spacewalk

(PET 5:20; 11:35am EST): Marshburn is stowing the foot restraint he used to ride on the end of the robot arm during today's antenna replacement work; Barron is breaking torque on bolts holding a P4 solar array power component in place to make future replacement easier

(PET 5:57; 12:12pm EST): Marshburn and Barron are headed back to the airlock to wrap up today's spacewalk

EVA Youth & Experience Tackle Tricky S-Band Antenna Replacement
by Ben Evans Dec, 2021

The oldest and youngest Americans ever to perform a session of Extravehicular Activity (EVA) outside the International Space Station (ISS) spent six hours and 32 minutes in open space on Thursday, labouring to remove and replace a hard-failed S-band Antenna Subsystem Assembly (SASA) from the P-1 truss segment. Sixty-one-year-old Tom Marshburn, making the fifth spacewalk of his career, and 34-year-old first-timer Kayla Barron deftly removed the faulty antenna and replaced it with an on-orbit spare from ExPRESS Logistics Carrier (ELC)-3. They also attended to a number of get-ahead tasks, before heading back inside the Quest airlock.

Dragon zmierza do ISS
  21.12. o 10:07:08 z KSC wystartowała RN Falcon-9R. Wyniosła ona w T+8' 40" na orbitę transportowy statek kosmiczny Cargo Dragon do misji SpX-24. Połączy się on z ISS 22.12.2021 o 09:25:08. Połączył się on z ISS 22.12.2021 o 08:41  Pierwszy stopień RN (B1069.1) w T+8' 44" wylądował na barce ASDS JRTI na Atlantyku.
Było to setne udane lądowania pierwszego stopnia tego typu rakiety.

CRS-24 Dragon Launches, Heads to Space Station
by Ben Evans December 21, 2021



(...) Three Cargo Dragons, three Crew Dragons—including September’s historic, all-civilian Inspiration4—established an (almost) unbroken presence of at least one SpaceX vehicle in orbit throughout the year. (...)

(...) In readiness for CRS-24’s arrival, the Expedition 66 crew have been preparing hardware and rehearsing procedures in the last few days. Last week, they resized Extravehicular Mobility Unit (EMU) No. 3006.

This particular space suit—most recently worn by spacewalker Shane Kimbrough last June—also had its EMU Data Recorder (EDaR), EDaR Antenna, EDaR Antenna Cable and High-Definition EMU Camera Assembly (HECA) removed. EMU No. 3006 will return to Earth aboard the Cargo Dragon in January for refurbishment, having supported 20 sessions of Extravehicular Activity (EVA) since 2017. (...)

ISS wygląda na perspektywiczną konstrukcję. 2030 to taka cezura na okrągło, ale czy ostateczna ?

Biden-Harris Administration Extends ISS Operations Through 2030

(...) “The United States’ continued participation on the ISS will enhance innovation and competitiveness, as well as advance the research and technology necessary to send the first woman and first person of color to the Moon under NASA’s Artemis Program and pave the way for sending the first humans to Mars,” Nelson continued. “As more and more nations are active in space, it’s more important than ever that the United States continues to lead the world in growing international alliances and modeling rules and norms for the peaceful and responsible use of space.” (...)

Przedłużać na papierze pewnie sobie mogą i w nieskończoność, natomiast zastanawia mnie czy oni uwzględniają stan techniczny przynajmniej tych najwcześniejszych modułów, np. ZARJI, w której wykryto podziurawione poszycie. Stacja ma już 23 lata (licząc właśnie od tego modułu), także dopóty nie ma AXIOM'a na orbicie (który ma rosnąć "na pempowinie" ISS) - dopóty taka eksploatacja stacji "do upadłego" nie wydaje się być rozsądnym posunięciem.
