Former NASA Administrator Mike Griffin joins the Space Policy Edition to discuss his notable 2007 speech outlining the tension between so-called “real” and “acceptable” reasons for space exploration.

“Acceptable” reasons for space exploration are logical, policy-friendly justifications such as workforce development, technology spinoffs, and STEM engagement. They are quantifiable and dispassionate — the Vulcans of arguments.

The successful landing of IM-1 on the Moon ushered in a new era of commercial lunar exploration, one that has little to no historical precedent. The future, still highly uncertain, is rich with promise for what commercial payload deliveries can provide. There will be new and more frequent science opportunities, lower-cost access for national and non-state actors, and, potentially, a path to a sustainable presence on the lunar surfa...

It’s a policy paper episode! Laura Delgado López joins the show to break down “Clearing the Fog: The Grey Zones of Space Governance” by Jessica West and Jordan Miller. Grey zones are harmful or disruptive space activities that fall short of provoking a military response — ideally. But the ambiguity, by its nature, could generate unplanned escalation and conflict.

What are these grey zones, and why do they exist? What are their con...
