NASA postponed the next Dragon resupply mission to the International Space Station (ISS) after an issue with the Station’s Main Bus Switching Units (MBSUs) – a component of the ISS United States Orbital Segment (USOS) Electrical Power System (EPS) – was observed this week. The CRS-17 launch was slipped to Friday while the issue was being evaluated. However, work to restore the redundant string to the robotic arm that will capture Dragon went to plan, initially with the use of jumpers, followed with a robotic changeout of the faulty MSBU on Thursday.
