Cislunar Development: What to Build— and Why  discusses the possible applications for cislunar space—for example, outposts on the moon, extraterrestrial mining operations, interplanetary waystations—and determines the infrastructure that will be needed to realize those ambitious goals. Author Dr. James Vedda, senior policy analyst with CSPS, says that the cislunar region remains a largely underdeveloped resource, and any coherent, long-term strategy for space commerce and exploration will need to make better use of it.

“An enduring, multi-purpose space infrastructure means more than just rockets and spacecraft,” said Vedda. “It needs a wide range of capabilities, such as inter-orbital transportation, on-orbit servicing, standardization, fuel storage, energy distribution, communication and navigation services, resource extraction, and materials processing.”

Vedda added that visions for cislunar development have been proposed by public and private stakeholders in spacefaring countries, but no widespread consensus on what to build and how to build it has emerged.

“Most of these concepts have focused on small aspects of the overarching design—but to truly realize the enormous potential of cislunar space, infrastructure projects should strive for broad applicability, beyond a single mission or short-term series of missions for a single agency.”

Dr. Jamie Morin, executive director for CSPS, echoed those sentiments, noting, “Investment in cislunar development makes sense as a strategy for boosting U.S. space commerce and expanding the human footprint in the solar system. Building an effective space infrastructure will involve a mix of government agencies and private-sector entrepreneurs from around the world, so collaboration between the public and private sectors and across national lines will be key.”
