....or even postponed if there's a risk of ammonia flying around?

Do we know the coolant fluid is ammonia? The Soyuz and Progress loops used other substances.

I've seen it described as "toxic". I'll amend my post

US EVA-89: A planned spacewalk Thursday by ISS astronauts Loral O'Hara and Andreas Mogensen has been called off to give engineers more time to assess any possible impacts due to a coolant leak Monday in a Russian lab module radiator (1/2)

US EVA-89: The spacewalk likely will slip a week or so, but a date won't be set until engineers complete their review; no major issues are anticipated, but the EVA is not considered "urgent," officials say, and the slip poses no major impact (2/2)

NASA PA has finally spoken

Spacewalks Postponed as Managers Review Leak Data

NASA engineering and flight control teams are continuing to review data and video associated with a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module (MLM). Two United States segment spacewalks originally scheduled for Thursday, Oct.12, and Friday, Oct. 20, have been postponed until the review is complete. New dates will be announced later.

The leak has now ceased, as was reported by Roscosmos flight controllers and evidenced by NASA external station camera views, which show only residual coolant droplets.

The primary radiator on Nauka continues to work normally, providing full cooling to the module with no impacts to the crew or to space station operations.

The backup radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April.

Teams on the ground continue to investigate the cause of the leak, and additional updates will be made as soon as available.

Jaws is starting any activity to swap out the two EMUs currently in the airlock for 3003 and 3009.  No details on why this is being done but she asked about the plans for 3009.  EVA is not on console yet so an answer is pending.

Update--Satoshi is doing SAFER related practice and clarification is to use suits already in the airlock

Spacewalks Rescheduled as NASA Reviews Leak Data
NASA astronaut Loral O'Hara is pictured trying on her spacesuit and testing its components aboard the International Space Station ahead of an upcoming spacewalk.

Two United States operating segment spacewalks outside the International Space Station have been rescheduled for no earlier than Thursday, Oct. 19, and Monday, Oct. 30, as a result of ongoing review by NASA managers and engineers after a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped.

During the first spacewalk NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andreas Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. Spacewalk 89 will be the first spacewalk for both crew members.

During the second spacewalk, O’Hara and Jasmin Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna bracket and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth. During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2. U.S. Spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara.

Details on times for the spacewalks are being reviewed and times for live coverage on NASA Television, the agency’s website and the NASA app and will be shared once available.

EVA 89 now set for Oct. 30, 2023, 1205 UTC:

Quote
The next NASA spacewalk will see Moghbeli and O’Hara set their spacesuits to battery power at 8:05 a.m. on Oct. 30 signifying the start of their first excursion together. The duo will spend about six-and-a-half hours removing electronics gear and replacing solar array hardware on the outside of the station.

NASA's Blog writer must be sick.  They actually bothered to send an update via a press release

Oct. 19, 2023

MEDIA ADVISORY: M23-130

Watch Live as NASA Astronauts Conduct Spacewalk, Upgrade Space Station

Two NASA astronauts aboard the International Space Station will conduct a spacewalk Monday, Oct. 30, to complete maintenance activities at the orbital complex.

Live coverage of the spacewalk begins at 6:30 a.m. EDT on NASA Television, the NASA app, and the agency’s website. The spacewalk is scheduled to begin about 8:05 a.m., and last about six-and-a-half hours.

NASA astronauts Jasmin Moghbeli and Loral O’Hara will exit the station’s Quest airlock to remove an electronics box called the Radio Frequency Group from a communications antenna on station. They also will replace one of 12 trundle bearing assemblies on a solar alpha rotary joint. The bearings enable the station’s solar arrays to rotate properly to track the Sun as the station orbits the Earth. When looking at the space station, the antenna is on the starboard (right side) truss, and the rotary joint is on the port, or left side.

U.S. spacewalk 89 will be the first for both Moghbeli and O’Hara. Moghbeli will serve as extravehicular activity crew member 1 and will wear a suit with red stripes. O’Hara will serve as extravehicular crew member 2 and will wear an unmarked suit.

Station managers continue planning for another spacewalk with O’Hara, as well as ESA (European Space Agency) astronaut Andreas Mogensen, to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. That spacewalk, which now is U.S. spacewalk 90, has been postponed to no earlier than December.

EVA now postponed to November 1, 2023:

Quote
The Expedition 70 crew is gearing up for another spacewalk planned at the beginning of November for maintenance on the outside of the International Space Station. The next United States orbital segment spacewalk now is scheduled for Wednesday, Nov. 1, to allow the International Space Station crew and flight control team additional time to prepare for the excursion.

NASA astronauts  Loral O’Hara and Jasmin Moghbeli will exit the station’s Quest airlock to remove an electronics box called the Radio Frequency Group that was part of a communications antenna system. They also will replace one of 12 trundle bearing assemblies on the station’s port solar alpha rotary joint. The bearings enable the station’s solar arrays to track the Sun. The spacewalk was previously planned for Monday, Oct. 30.

ISLE protocol underway.  There was a long gap in comms being heard on the ISS youtube feed.

Donning SAFERs.

Cheshier remarks that this is the 4th all-female spacewalk (after 3 by Koch and Meir in late 2019 / early 2020).

Edit - also they're currently 20 minutes ahead of schedule.

Jasmin Moghbeli is ready to go - she's been moved into the crew lock portion of the airlock. Now to get O'Hara's SAFER installed.

Edit - O'Hara is using SAFER 15, Moghbeli's got SAFER 13.

Installing O'Hara's SAFER.

(And this is where I hurry up and shower and drive to work before the EVA starts, so if anyone wants to pick up commentary go right ahead!)
