Rubio's first main cleanup task is to secure the beam restraints (which the top iROSA sat on, and had to be removed to access the lower one) to the pallet that brought up the two iROSAs, while Cassada is retrieving the APFR from the SSRMS.

Rubio quips that this is the closest he's been to an APFR in three EVAs. Cassada responds that he'd be glad to hand it over if Frank wants it.

Moving to and into the airlock:

SPARTAN reports new solar array is generating electricity.

Congratulations via Capcom from Mission Control.

Hatch close.

Concluding remarks as the astronauts hook their EMUs back up to the ISS - CAPCOM notes that "you made it look easy and routine... you've got a lot of people who are very glad that their holiday plans are still secure."

Cassada responds that he and Frank are going to put in for some leave.

Repressurization has begun, concluding the spacewalk at 3:27 pm Eastern Time / 2027 UTC for a duration of 7 hours 8 minutes.

Today's EVA statistics and webcast sign-off.

Thumbs up to the entire EVA team! And thank you, Joachim and Yellowstone, for your assistance covering the EVA for this thread!

That's an early signoff, normally coverage continues until the helmets are off... The crew is currently being serenaded by a someone singing "IROSA Rock" from Mission Control.

NASA Spacewalkers Install Station’s Fourth Roll-Out Solar Array

Expedition 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.

Not sure where the best place to put this.

Per Rob Navias via email

The iROSA FSE / carrier is not loaded / departing with CRS-26.
It will instead be jettisoned via the SSRMS

My 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

Interesting. So out of curiosity when jettisoned via the SSRMS how long should it take to reenter?

Is this a big deal re orbital debris mitigation/avoidance?
