time of closest approach was 1017 central.  PDAM may replace planned reboost scheduled later this week.  No new date on EVA

crew was 30 minutes ahead on the timeline and asked if they would have been held--for day/night pass timing?  The response was yes, they would have been held.

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.

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 Spacewalk

The 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.

If the identification of the object above is correct, then this Fregat had a RUD in 2020 resulting in at least 65 trackable pieces of debris.

CAPCOM update.  EVA on track for tomorrow although another red debris conjunction is currently being tracked prior to the start of EVA prep.  Updates to follow.

The crew asked for an update on tomorrow's timeline.  CAPCOM responded all times are expected to shift 45 minutes to the right.

NASA astronauts Frank Rubio and Josh Cassada are now scheduled to begin a spacewalk at 8:30 a.m. EST Thursday to augment the International Space Station’s power generation system. Wednesday’s spacewalk was postponed for 24 hours so that the orbiting lab’s ISS Progress 81 cargo craft could fire its engines at 8:42 a.m. to maneuver the station and avoid an approaching piece of rocket debris.

Spacewalkers Rubio and Cassada will install another roll-out solar array, also known as an International Space Station Roll-Out Solar Array (iROSA), on the space station’s truss structure. This time the duo will maneuver to the opposite side of the station and install the fourth iROSA on the Port-4 truss structure. The external installation job will last about seven hours and broadcast live on NASA TV on the agency’s app and its website.

Expedition 68 Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) will operate the Canadarm2 robotic arm to support the spacewalkers during the fine-tuned iROSA installation job. The duo will also assist Rubio and Cassada in and out of their spacesuits, also known as Extravehicular Mobility Units (EMUs), in the Quest airlock before and after their spacewalk.

While Thursday’s spacewalk is under way, NASA space station program manager Joel Montalbano and Roscosmos human spaceflight executive director Sergei Krikalev will hold an audio-only media teleconference 11 a.m. The two space executives will discuss the ongoing investigation of an external leak detected on the Soyuz MS-22 crew ship on a live audio call streaming on NASA’s website at https://www.nasa.gov/live.

The three cosmonauts representing Expedition 68, Commander Sergey Prokopyev and Flight Engineers Dmitri Petelin and Anna Kikina, stayed focused on lab maintenance servicing and cleaning a variety station hardware today.

Crew has checked in from the airlock as EVA preps have begun.  Looks like the 45 minute slide right on the timeline is correct.

 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.
