The Outer Space Treaty, the leading source of law for activities in space, has laid out various limitations and regulations regarding actions in space and how space can be used. One of these limitations is commonly referred to as the “non-appropriation principle.” The non-appropriation principle prohibits nations from making claims of sovereignty over ...

Mining the space of graph properties
Proceedings of the tenth ACM SIGKDD international conference on Knowledge discovery and data mining, 2004Existing data mining algorithms on graphs look for nodes satisfying specific properties, such as specific notions of structural similarity or specific measures of link-based importance. While such analyses for predetermined properties can be effective in well-understood domains, sometimes identifying an appropriate property for analysis can be a ...

U.S. space policy: Multilateral mining
Science, 2020In their Policy Forum “U.S. policy puts the safe development of space at risk” (9 October, p. 174), A. Boley and M. Byers claim that U.S. plans to purchase a small amount of commercial Moon resources put the safe development of space at risk. To the contrary, U.S. actions are poised to help jumpstart a new age of space innovation that has the potential
