The station's airlock will be used for the departure of the two people. The extravehicular crewmember 1 will wear a spacesuit with red stripes and the extravehicular crewmember 2 will wear a suit with no stripes.

The duo will translate the Starboard-4 structure and install modification kits that will ready the space station for its third roll-out solar array.

Two of the planned six iROSAs have already been deployed on the station. NASA officials said during a press conference on Monday that the next two will come up to the space station on a cargo capsule.

The space station's total available power will increase from 160 kilowatts to 215 kilowatts as a result of the installation of all six iROSAs.

Tuesday will be the second spacewalk for Barron and the first for Chari.

There will be another spacewalk on March 23, with crew members to be named later. The installation of new hoses in the ammonia system is one of the maintenance work that will be done next week.
