'No Impacts' to Expedition 45 Crew, as 1B Channel on S-6 Truss Suffers Power Loss

The S-6 truss and its two expansive Solar Array Wings (SAWs) are deployed during the STS-119 shuttle mission in March 2009. “Channel 1B”, one of the two power channels aboard the S-6 truss, is believed to have fallen victim to a power short, which tripped its Direct Current Switching Unit (DCSU). The cause has been traced to the failure of the channel’s Sequential Shunt Unit (SSU), for which a replacement is expected to be launched and installed in 2016. Photo Credit: NASA
