MEDIA ADVISORY M22-030
NASA to Air Briefing, Spacewalks to Upgrade Space Station

Crew members from International Space Station Expedition 66 will conduct two spacewalks Tuesday, March 15, and Wednesday, March 23, to continue upgrades to the orbiting laboratory.

NASA will discuss the upcoming spacewalks during a news conference at 2 p.m. EDT Monday, March 14. Live coverage of the news conference and spacewalks will air on NASA Television, the agencyís website, and the NASA app.

News conference participants are:

    Joel Montalbano, manager, NASA International Space Station program
    Dina Contella, operations integration manager, NASA International Space Station program
    Mike Lammers, March 15 spacewalk flight director
    Sandra Moore, March 15 spacewalk officer
    Paul Konyha, March 23 spacewalk flight director
    Sandra Fletcher, March 23 spacewalk officer

Media wishing to participate in the briefings in person must request credentials from the Johnson newsroom at: 281-483-5111 or [email protected] no later than noon Friday, March 11. Media interested in participating by phone must contact the Johnson newsroom by noon Monday, March 14. Those wanting to submit a question on social media may do so using #askNASA.

Coverage will begin at 6:30 a.m. for the Tuesday, March 15, spacewalk, which will begin around 8:05 a.m. Coverage will begin at 7:30 a.m. for the Wednesday, March 23, spacewalk, which will be begin around 8:50 a.m. Both spacewalks will last approximately 6 hours, 30 minutes.

NASA Flight Engineers Kayla Barron and Raja Chari will conduct the Tuesday, March 15, spacewalk, designated U.S. EVA 79, assembling and installing modification kits required for upcoming solar array upgrades. The pair will install brackets and struts to support the future installation of an ISS Roll-Out Solar Array (iROSA). So far, two of six iROSAs have been deployed on station with four additional arrays to be delivered. The arrays will ultimately augment six of the stationís eight power channels, increasing the stationís total available power from 160 kilowatts to up to 215 kilowatts.

Barron will serve as extravehicular crewmember 1 (EV 1) and will wear a suit with red stripes. Chari will serve as extravehicular crewmember 2 (EV 2) and will wear a suit with no stripes. The spacewalk will be the second of Barronís career and the first for Chari.

For the Wednesday, March 23, spacewalk, designated U.S. EVA 80, two astronauts will install hoses on a Radiator Beam Valve Module that routes ammonia through the stationís heat-rejecting radiators to keep systems at the proper temperature. The crew members will also install a power and data cable on the Columbus moduleís Bartolomeo science platform, replace an external camera on the stationís truss, and conduct other upgrades to station hardware.

Astronaut roles for the Wednesday, March 23, spacewalk will be confirmed after the first spacewalk is completed.

I felt a little bit of vertigo watching that video! It's easy to forget how dangerous working outside the ISS can be. Johnson posted a video of Spacewalk 79 and 80:

Here's to an easy and successful EVA! Much luck!
