259 SYSTEMS: ROBOTICS—THE CONSTRUCTION EQUIPMENT FOR THE INTERNATIONAL SPACE STATION CHAPTER 15 e.g., capturing a visiting vehicle or supporting a spacewalk—the on-board astronauts will execute the procedure. In addition to providing the hardware, CSA also provided flight controllers to operate the MSS. Whereas the other international partners control their contributions from a control center in their host countries with their own flight director, the MSS is controlled from Houston, Texas, under the supervision of the NASA flight director. In Houston, the system team, led by the ROBO (see Introduction) is made up of approximately 50% CSA employees. Initially, the CSA robotics support room in Montreal provided primarily engineering support during robotics operations, which was the equivalent of the Mission Evaluation Room discussed in the Introduction. Over time, the capabilities of the facilities and operators in Montreal grew. Today, it now serves as a control center. Here, the MSS systems and MSS task flight controllers support the ROBO (Introduction Figure 10) and, on occasion, ROBO supports from Montreal with the backroom support in Houston (Figure 13). Figure 13. Expedition 47 ROBO Jason Dyer (CSA) on console in Mission Control Center-Houston during rendezvous with Orbital/ATK Cygnus OA-6 cargo vehicle in March 2016. Various data are displayed on the computer monitors including a graphical display below the ROBO sign on the left, similar to what the astronauts use, showing the current position of the robotic arm. On the left side of the front wall displays are six images from external cameras on the ISS. The middle wall display tells the flight director (not shown) the location of the ISS in relation to the Earth, as well as the vehicle orientation. The far-right display shows the commands being sent to the ISS and any alarms that are present. In the early days of robotic operations on the ISS, the flight control team powered the MSS on or off but left the dynamic operations to the crew. After a serious ISS computer system failure on STS-100/ISS-6A (see below), the team began to imagine how operating the robotic systems from the ground could actually work. Today, many of the SSRMS operations, all translations of the systems using the Mobile Transporter, and all of the SPDM operations are actually performed by the ground team. The Bigelow Expandable Activity Module was installed in April 2016, completely by the ground team. The astronauts performed only the time-critical steps with the Common Berthing Module.
