A Proposed Legal Framework On The Extraction And Consumption Of Outer Space Resources
<p>The future of space exploration endeavors depends highly on the utilization of in-situ resources. Large scale exploration road maps take advantage of local resources to reduce mission costs and enable the growth of revolutionary self-sufficient technologies to prolong mission duration and reach …
