An Inchoate Process For The International Regulation Of Military Activities In Space, Baker Spring

Space and Defense

As the breadth and depth of military activities in space expand, demands are growing to regulate these activities at the international level. In some cases, these demands stem from the recognition that broader national security operations in space are moving away from a legacy of being dominated by secret intelligence activities and in the direction of more open military activities.1 In other cases, they are driven by the efforts of arms control advocates to roll back the “weaponization of space.”2 Regardless of the underlying motivations, the demands for international regulation are going to grow, and the debate will turn increasingly …

Space Deterrence Or Dominance?, Dwayne Liller

Space and Defense

A strategy to safeguard United States’ space assets is needed. Deterrence strategies, like Cold War nuclear deterrence, are often recommended. Nuclear deterrence history reveals that deterrence through dominance is what early strategists employed. Both Cold War adversaries attempted repeatedly to gain the lead in nuclear weapons. Seeking short term advantages activated the security dilemma and both sides responded in kind, guaranteeing an arms race. The faulty logic of the security dilemma was that the next advantage would bring security. This did not happen and illustrated how mutual vulnerability resulted from long term and determined opposition. That condition exists to this …

The New Space Order: Why Space Power Matters For Europe, Nicolas Peter

Space and Defense

More than fifty years since the dawn of the Space Age and twenty years since the end of the Cold War, space affairs and politics remain interlinked. Space activities are increasingly tied to national power for major world powers, and political objectives are still the driving force for most space activities.

The importance of space activities is increasing, transitioning in terms of …

Thailand Post King Bhumibol Adulyadej: An Uncertain Future, Daniel Hughes

Space and Defense

Student Contribution

If tourism were proportional to political stability in the sense that more people would want to travel to destinations in which they are ensured some semblance of security, then Thailand would indeed be one of the most stable and secure countries in the world, particularly in 2011 according to Forbes and Lonely Planet travel blogs. The truth, however, is that Thailand is simply a country that has done well to mask its political turmoil with the exception of the Bangkok riots of 2006. In reality, Thailand is a whirlpool of political deception, monarchical clandestine operations, and military intervention. …

International Space Negotiations, Emerging Space Powers, And U.S. Efforts To Protect The Military Use Of Space, Justin Anderson, Walt Conrad, Sarah Jacobs Gamberini

Space and Defense

In recent years strategists and diplomats from space faring nations have engaged in debates with their foreign counterparts (and in some cases, with each other) on a range of issues related to norms and laws – or the relative lack thereof – applicable to the military use of space. Questions have run the gamut from the very broad (should the slim volume of outer space law relevant to military platforms and operations be expanded?) to the very specific (what new technical tools are available for the verification regime of a notional future space arms control agreement?).

Meeting Growth Challenges Of Mexico Aerospace: The Queretaro Cluster, Monica Casalet

Space and Defense

Growing the Aerospace sector in Mexico requires multilevel agreement between original equipment manufacturers (OEMs), including foreign companies, and national and sub-national governments to stimulate programs and instruments for sector growth.

A Definition Of Reliable Water Supply For Public Water Systems, Easton Hopkins

Theses and Dissertations

"Reliable water supply" does not have a universal definition in Utah, or the Western United States, where water resources are limited and such a definition would be especially useful. Utah's three water agencies and 500 public water systems have no consistent method to define, evaluate, and report it, potentially leading to an inability to meet regulatory water demands. We propose a unified definition of reliable water supply for Utah's public water suppliers that can also be used elsewhere. The qualitative definition we propose is necessary to precede quantitative evaluations, set policy, and provide consistency to water resources management in Utah. …
