PREFACE

The International Space Station (ISS) to Commercial Orbital Transportation Services (COTS)

Interface Requirements Document (IRD) defines physical and functional interfaces and interface requirements between the ISS and COTS.

The contents of this document are intended to be consistent with the task and products to be prepared by the ISS Program as defined in SSP 41000, International Space Station System

Specification. This IRD shall be implemented on all new ISS Program activities and shall be included in any existing contracts through contract changes. The initial release and Revision A of this document were under the control of the Space Station Program Control Board (SSPCB).

The SSPCB delegated control authority for SSP 50808 to the Transportation Integration Control

Board (TICB) as documented in the ISS MD 1013, Charter for Transportation Integration

Control Board.
