Abstract

<strong>PURPOSE</strong><br>The purpose of this document is to define the Microgravity Science Glovebox (MSG) investigations integration process. The MSG Level&#160;III Configuration Control Board (CCB) controls this document per MSFC-PLAN-2781. The MSG project has simplified the Investigations integration requirements to minimize the International Space Station (ISS) integration requirements. This document contains the development and integration template meeting ISS and MSG unique integration requirements. The following sections will describe the applicable documents, the integration process, operations process, data deliverables, safety process, verification and flight certification, and the Configuration Management process. In addition, responsibilities have been included to show interactions and relationships between the MSG Investigation Integration Team (IIT) and the Investigation Developer Team (IDT). The IIT has provided some flexibility in meeting the overall ISS payload template as defined by Appendix A. The IIT will maintain a unique schedule for each increment, defining the specific deliverable milestones.<br>The MSG Facility provides a sealed work volume (0.26m³ with a cleanliness of 100K), resources, and ancillary equipment for performing crew-operated and/or tele-operated investigations, which require isolation from the cabin atmosphere. The resources include general utilities (power, cooling, gaseous nitrogen, vacuum) computer control with data logging support, and extensive imaging capability. In the sealed mode, the MSG serves as a single level of containment facility by providing a physical barrier. In the air circulation mode the MSG serves as a one-failure tolerant containment facility by providing a physical barrier and a negative pressure relative to the cabin.<br>The MSG facility was developed by the European Space Agency (ESA). Ownership has been transferred to the National Aeronautics and Space Administration (NASA). The MSG Team within the Space Systems Programs/Projects Office at the Marshall Space Flight Center (MSFC) is responsible for overall MSG project management, investigation integration, and operations.<br>The IIT at MSFC is composed of the Investigation Payload Integration Managers (IPIMs) MSG Lead Test Engineer (MLSTE), Operations Engineers, Command & Data Handling (C&DH) Engineers, Test Engineers, S&MA Engineers, a core group of discipline engineers, and support personnel. The IIT provides the interface and safety requirements, schedule for meeting ISS template milestones, administrative support for documenting interfaces to the MSG facility, investigation manifesting, analytical integration, integrated testing and flight operations. The IIT will support the IDT in assuring that the engineering interfaces to the MSG and ISS are compatible. The IIT will input investigation data into the ISS Program Data Bases and manage the integrated resources.<br>The IDT is a combination of the Glovebox Investigator (GI) or Principal Investigator (PI) and the investigation developer. The GI or PI is responsible for defining the science requirements for the investigation. These requirements are flowed into performance requirements of the investigation hardware to be developed. The investigation developer is responsible for the design, development, and delivery of the investigation hardware that will satisfy the science requirements of the GI or PI and meet the safety and interface requirements, as defined by the IIT. The IDT is responsible for the conduct of the investigation science operations, defining the data or products required from the operation of the investigation hardware, and providing scientific support during physical integration and flight operation of the investigation hardware.
