Both mid struts were telescopic and were locked in place once extended to the right length.Ī final task for the spacewalkers was to be the release Multi Layer Insulation (MLI) covers and “break torque” on bolts for two spare Battery Charge Discharge Units (BCDUs) located nearby on the S6 Truss. The triangle structure was then mounted to the base of the 3A Mast Canister Assembly on the S4 truss via a center pad.Ī left lower strut and left mid strut were then installed, with a right lower strut and right mid strut following on the opposite side. Specifically, an upper triangle was assembled by connecting a right upper strut to a center mounting bracket, following which a left upper strut was connected on the opposite side.

The mod kit installation procedures involved assembling a frame out of several struts and bolting it to the base of an existing solar array, all using a Pistol Grip Tool (PGT). The EVA procedures were essentially the same as performed on EVA-77 in September 2021, which installed a mod kit on channel 4A on the P4 Truss. Installing them on top of the existing arrays allows them to utilize the same sun-tracking motors, and the new arrays will ensure the ISS has adequate electrical power to support all requirements throughout the rest of its projected lifetime to 2030. While the IROSAs are around half the size of the SAWs, they are around twice as efficient, meaning they produce about the same amount of power. The IROSAs are gradually being installed on top of six of the station’s eight Solar Array Wings (SAWs) to increase the ISS’s electrical power output from its current level of 160kW up to 215kW.Īdding six new, smaller arrays – built by Boeing – is necessary due to degradation in the power output level of the SAWs, some of which have now been on-orbit for over 20 years.

The mod kit is essentially a mounting frame that will allow future spacewalkers to install a new ISS Roll Out Solar Array (IROSA) as part of the ongoing ISS Power Augmentation (IPA) program. The spacewalk officially began at 12:12 UTC and concluded at 19:06 UTC and was dedicated to installing a so-called “mod kit” on power channel 3A’s Mast Canister Assembly (MCA) located on the Starboard-4 (S4) Truss.

The Extravehicular Activity (EVA, or spacewalk) – US EVA-79 – was performed by astronauts Kayla Barron and Raja Chari and was second spacewalk at the station this year and the 247th EVA for construction, operation, and maintenance of the International Space Station (ISS) overall. The spacewalk kicked off a busy period of upcoming operations amid the continued uncertainty over the future of Russian co-operation on the ISS. Two NASA astronauts have completed 6.5-hour spacewalk to continue the process of upgrading the space station’s power systems.
