Transcending Space and Time: The emerging urban morphosis around spaceports
… could be tailored for building cities around spaceports identifying various obstructions existing around them. And it is later tested with one of its kind – a potential growth site with its very own local contextual conditions. The distinctive design decisions and solutions provided consider …

Forecast Verification of the Current Icing Potential (CIP) to Predict Lightning Hazards at U.S. Spaceports
<p>Government spaceports employ extensive lightning detection networks that may not be available at commercial spaceports. Therefore, the Federal Aviation Administration identified the need for diagnosing the threat of triggered lightning without in-situ measurements. Anecdotal observations of the …

From the Earth to the Moon: Economic Viability of Commercial Spaceports & Science and Technology Planning for MIT Lunar Exploration
… to demand, there are 11 existing commercial spaceports in the United States and at least another six under consideration. While a spaceport can bring economic growth and STEM development to a region, it requires significant and sustained investments of public funding in an uncertain and …

How Geographic Proximity to the Kennedy Space Center Effects Attitudes Relating to NASA
… chance of generating support for NASA are spaceports due to the rocket launches they support serving as focusing events for NASA. Rather than focusing as past scholars have on specific regions, this research examines driving distance from the Kennedy Space Center to provide more detail …

Assessment of the potential for developing a micro-launcher industry in South Africa
… micro-launcher initiatives and the majority of spaceports in use are located in the northern hemisphere, and there are currently no operational spaceports in Africa. In this study the potential for developing a micro-launcher industry in South Africa is explored, building on the launch …

Building a 21st Century Multi-User Commercial Spaceport: Development and Application of the Spaceport Readiness Level Scale
<p>Commercial spaceports have arisen over the last decade and a half to support a growing commercial space marketplace. The introduction of expected suborbital launch capabilities for tourism and for orbital launch operations at an increased cadence has demonstrated a need for more capability at …

A Gap Analysis of Meteorological Requirements for Commercial Space Operators
… of the space industry and those living around spaceports; but, are they adequate? Perhaps the commercial space industry can turn to the commercial aviation industry to help answer that question. Throughout its history, the aviation industry has dealt with lessons learned from mishaps due to …

Air traffic management and conflict analysis for reusable launch vehicles
… of the launch markets. Increased utilization of Spaceports will increase the frequency of interruptions to normal airspace operations and new methods of Aircraft-RLV separation need to be examined to reduce the impact of these operations on the National Airspace System. In this work, the issues …

Redefining “Space Sustainability” for Launch Vehicles: Forecasting the Atmospheric Impact of the Commercial Space Launch Industry in 2050
… of heavy-lift launch vehicles across origin spaceports. We simulate the chemical interactions of the launch plumes with the atmosphere using the global atmospheric chemistry model GEOS-Chem High Performance (GCHP). Finally, we quantify the steady state impact of launch emissions on …

Tight Discrete Formulations to Enhance Solvability with Applications to Production, Telecommunications, and Air Transportation Problems
… (SUA) restrictions prompted by launches at spaceports or weather considerations, this model prescribes a set of flight-plans to be implemented. The model formulation seeks to minimize a delay and fuel cost based objective function, subject to the constraints that each flight is assigned one …
