Publishers Corner Manned Space Exploration: America’S Folly, Roger G. Harrison

Space and Defense

Publishers Corner: Essays

If we want to assess the benefits of human space exploration, particularly to Mars, who better to consult than the good folks at MIT, a place presumably bristling with engineering knowledge and human genius. Fortuitously enough, the “Space, Policy and Society Research Group” at MIT has produced a study on “The Future of Human Space Flight” for our edification and enjoyment. It is six years old at this writing, but the facts have not altered appreciably: the humans who would have to be transported to, sustained on, and returned from the red planet are the same frail …

Book Review The Strategist: Brent Scowcroft And The Call Of National Security By Bartholomew Sparrow (Public Affairs, 2015), Schuyler Foerster

Space and Defense

A popular new biography pays overdue tribute to a living legend. Bartholomew Sparrow’s rich and detailed biography of Brent Scowcroft—a still very active and now nonagenarian—has been on bookshelves since early this year. Many, including those who have an intimate familiarity with some of the events and personalities in this book, have already offered thorough reviews of the work.

Terror On High: Deterring Asat, Stephen Shea, Mathew Johnson, Alfredo Zurita

Space and Defense

Student Contribution:

As technology becomes even more pervasive in daily life, valuable and relatively vulnerable space assets will inspire greater desire to attack U.S. power through space.1 As a result, Anti-Satellite (ASAT) deterrence, a fledgling area of study, will need to be developed and addressed in detail. The proceeding essay will attempt to answer the following questions. What motivates space attacks? How will the enemy try to attack our space assets? What can be done to deter future ASAT attacks?

Cyber Deterrence: Is A Deterrence Model Practical In Cyberspace?, Nathaniel Youd

Space and Defense

Student Contribution:

After reconsidering massive retaliation versus escalation dominance concepts from nuclear deterrence, escalation dominance, investing in capability to respond proportionally at each level of cyber attack, may be the most practical and effective military strategy for strengthening cyber deterrence.

Argentina Space: Ready For Launch, Daniel Blinder

Space and Defense

Desire for a comprehensive space program, one that includes an indigenous satellite launch capability, motivated Argentina to strengthen relevant policy institutions and carefully reconsider its approach in foreign affairs. In the process, this space power on the semi-periphery bridged bitter domestic partisan differences on the federal budget and allayed security fears of the international community, fulfilling at least some important national objectives regarding economic development as well as Argentinean access to space.

Cyberwar: Clausewitzian Encounters, Marco Cepik, Diego Rafael Canabarro, Thiago Borne Ferreira

Space and Defense

As Clausewitz’s masterpiece suggests, language matters for how states conceptualize and plan for war. ‘Cyberwar’, now on the lips of nearly every national security policymaker, may turn out to be a misnomer.

Strategic Nuclear Weapons For Planetary Defense, James Howe

Space and Defense

The planet Earth is continually under bombardment. Each day, roughly 100 tons of small meteoroids and space debris – some as large as a meter in diameter, but most smaller than a grain of sand – strike the atmosphere. Moving at speeds in excess of 40,000 kilometers per hour, these meteoroids are often seen as bright streaks in the sky as they burn up from atmospheric friction. Fortunately, because they are consumed high in the atmosphere, meteoroids and space dust pose no threat to humans or other life on Earth.

Comparative Evaluation Of Investigation Methods For Estimating The Load-Dependent State Of Charge And End Of Discharge Of A Multirotor Uav Battery, Hanna Dibbern, Morten Roßberg, Claudia Werner

Journal of Aviation Technology and Engineering

As the scope of multirotor unmanned aerial vehicle (UAV) applications increases, more attention is being paid to UAV energy requirements, which vary depending on the mission profile. To obtain accurate information about the UAV battery during flight, the idea of a digital twin including a battery state estimation model is promising. For battery state estimation, a Kalman filter combination is the preferred approach in the literature. Comparing different Kalman filters, the unscented Kalman filter has a more accurate estimation for nonlinear systems compared to the extended Kalman filter. In the application of UAV flight with load-dependent flight missions, the comparison …

Publisher’S Corner Space Policy’S Salt Moment, Roger G. Harrison

Space and Defense

The market for a leap forward in space arms control is open. Now, who’s buying? The United States is facing a fundamental decision about space policy which arises from a question: does our national interest in an ordered space environment trump our absolute insistence on a policy of freedom of action? Or is the looming threat of over-crowded orbits, frequency interference and debris – of contested, congested and competitive space – so pressing that we must accept some greater transparency for our national security space operations, even greater information sharing with China, Russia, and commercial space operators, and perhaps some …

Book Review Crowded Orbits: Conflict And Cooperation In Space By James Clay Moltz (Columbia University Press, 2014), Deron Jackson

Space and Defense

A popular space primer serves both the policy and academic communities. Human beings have perceived outer space as infinite for centuries, and since the observations of Edwin Hubble in the 1920s, scientists have studied phenomena that suggest the universe itself is expanding. However, as the title of Clay Moltz’s most recent book points out, the region of space most important to the economic and physical security of residents on Earth is increasingly viewed as far from infinite.

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. In addition, space for local learning must be cultivated within a process of production organized hierarchically and highly regulated on the international level. The case of the Queretaro cluster is important due to the density of networks created, extensive public-private collaboration, and the emergence of specialized institutions to train and shape highly skilled (professionals and technicians) in the aerospace industry. Ultimately, there remains an important vacuum to fill in the …

Brazil Space: Military Dependency And The Case Of The Geostationary Satellite Of Defense And Strategic Communications, Gills Vilar Lopes

Space and Defense

In Brazil, there has been no transition model of space capabilities promoted by the military sphere (especially the Brazilian Air Force) for nurturing the civil one (Brazilian Space Agency). Drawing upon official documents and legislation as primary sources, the case study of the Geostationary Satellite of Defense and Strategic Communications (SGDC) is analyzed in light of the space strategic sector. Main factors that impede the PEB are related to military-technological dependence and poor resource management, with draconian budget cuts and projects canceled before having achieved realistic milestones.

Attack On The Brain: Neurowars And Neurowarfare, Armin Krishnan

Space and Defense

Is neurotechnology leading nation-states toward a new domain of war? Neuroscience is on the verge of deciphering the human brain. As a result, brains will become a part of the battlefield against which attacks will be directed. As neuroscientist James Giordano argued: “the brain is the next battlespace.” It is foreseeable that this will have tremendous implications for warfare and could amount to a true military revolution in the sense of military historian Williamson Murray: it would completely change the characteristics of conflict, as well as transform state and society.
