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

NASA will discuss the upcoming spacewalks during a news conference at 2 pm EDT 14 March. Live coverage of the news conference and spacewalks will air on NASA Television, the agency’s website, and the NASA app.

News conference participants are:

  • Joel Montalbano, Manager, NASA International Space Station programme
  • Dina Contella, Operations Integration Manager, NASA International Space Station programme
  • 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

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

NASA Flight Engineers Kayla Barron and Raja Chari will conduct the 15 March spacewalk, designated US 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 station’s eight power channels, increasing the station’s 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 Barron’s career and the first for Chari.

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

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