The recently released US Space Policy highlights the fact that the space environment is in a period of evolution and growth.  In particular, the policy notes: •    The space environment is rapidly changing and these changes will require a corresponding change in our actions. •    Greater international cooperation is desirable, including leveraging the existing and planned space capabilities of allies. •    “Responsible operations in space” are critical and this will necessitate improved information collection and sharing to avoid collisions and to protect critical space systems. •    The government should increase its reliance on commercial space activities and consider innovative approaches such as public-private partnerships. The policy recognizes that as more countries and more commercial entities develop space capabilities, there will be a need to better define the rules for responsible behavior in space.  As the space environment continues to grow and evolve, this will create new stresses on existing public and private law.  This paper examines current private sector initiatives to enhance data sharing between commercial satellite communications operators through the Space Data Association Limited (SDA).   It will discuss the international policy and legal implications of the SDA and the efforts being made by the participants to manage both legal and physical risk.
