EMU work ongoing is referring to suits for Koichi and Duke so it looks like they are doing this EVA. The EMUs are 3004 and 3009

Koichi and Duke are doing EMU comm checks from the airlock so they are definitely doing this EVA

The seven Expedition 68 crew members split their day between spacesuits and space science. A spacewalk to upgrade the International Space Station’s power system is planned soon as advanced microgravity research is ongoing aboard the orbital lab.

Astronauts Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) partnered together inside the Quest airlock readying a pair of Extravehicular Mobility Units (EMUs), or spacesuits, for an upcoming spacewalk. The pair were joined by NASA Flight Engineers Frank Rubio and Josh Cassada checking EMU components and preparing Quest ahead of the next spacewalk to prepare the station for its next roll-out solar array.

MEDIA ADVISORY M23-006
NASA to Provide Coverage of US Spacewalk, Preview News Conference


Two astronauts on the International Space Station will conduct a spacewalk Friday, Jan. 20, to install hardware for future power system upgrades. Experts will preview the work during a Tuesday, Jan. 17, news conference at NASA’s Johnson Space Center in Houston.

NASA will preview the spacewalk and provide live coverage of the power system upgrades on NASA Television, the NASA app, and the agency’s website.

The news conference will take place at 2 p.m. EST (1 p.m. CST) Jan. 17, with the following participants:

    Dina Contella, operations integration manager, International Space Station Program
    Chloe Mehring, spacewalk flight director
    Keith Johnson, lead spacewalk officer

U.S. media wishing to participate in-person must request news conference credentials from the Johnson newsroom no later than 5 p.m. EST Monday, Jan. 16, at 281-483-5111 or [email protected]. Media interested in participating by phone must contact the Johnson newsroom no later than one hour before the start of the briefing.

On Jan. 20, NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata will exit the station’s Quest airlock to complete the installation of two mounting platforms as part of planned solar array augmentation on the starboard side of the International Space Station’s truss.

The duo will complete the installation of a mounting platform on the 1B power channel that was started during a previous spacewalk and begin installing a mounting platform on the 1A power channel.

NASA will provide live coverage beginning at 7 a.m. EST. The spacewalk is scheduled to begin at 8:15 a.m., and last about six and a half hours.

The installation is part of a series of spacewalks to augment the International Space Station’s power channels with new International Space Station Roll-Out Solar Arrays (iROSAs). Four iROSAs have been installed so far, and two more will be mounted to the platforms installed during this spacewalk in the future.

Mann will serve as extravehicular crew member 2 (EV 2) and will wear an unmarked suit. Wakata will serve as extravehicular crew member 1 (EV 1) and will wear a suit with red stripes. The spacewalk will be the first for both Mann and Wakata.

Get breaking news, images and features from the space station on the station blog, Instagram, Facebook, and Twitter.

So happy for Koichi to be getting an EVA, after so long. He truly deserves it.

The lack of media interest in the update was truly disappointing...

Isn't this the first EVA where the commander is not EV1?

US EVA-84: In case the Soyuz MS-22 micrometeoroid impact 12/14 has you wondering, NASA says the calculated risk of a spacesuit penetration and oxygen leak of any size during a 6.5-hour EVA is in the neighborhood of 1-in-3,800; it's around 1-in-21,300 for a "critical" impact

US EVA-84: A critical impact in this context is one resulting in a penetration large enough to cause an uncontrollable loss of oxygen; NASA says the probabilistic risk assessment, emergency procedures, the suit's design and training combine to make make the risk acceptable
