Book Description
Federal Aviation Administration (FAA) regulations require the licensing of spaceports and launch vehicles, which includes the assessment of environmental impacts. The TRB Airport Cooperative Research Program’s ACRP Web-Only Document 51: Commercial Space Vehicle Emissions Modeling presents a user-friendly tool for practitioners to estimate the emissions associated with commercial space vehicle activity. Supplementary materials to the document include an Emissions Example Information & Users Guide, the RUMBLE application, and a RUMBLE User Guide.

Book Description
Abstract: "Commercial space launch vehicle activities are expected to continue to increase. As they begin testing and become operational, many noise issues as well as the effects from sonic booms will need to be evaluated. The Aviation Environmental Design Tool (AEDT) is designed to evaluate the effects of noise and emissions from aircraft, but doesn't have the ability to predict noise and sonic boom effects from commercial space operations. Two tools were developed in this project to predict noise and sonic boom to be used in the noise modeling evaluation process. RUMBLE 2.0 predicts rocket noise, and PCBoom4 was modified to predict sonic boom from commercial space operations. ACRP Research Report 183 is the user's guide for each tool, and ACRP Web-Only Document 33: Commercial Space Operations Noise and Sonic Boom Modeling and Analysis is the contractor's final report on the methodology and development of these tools."

Book Description
The lack of widespread education in space safety engineering and management has profound effects on project team effectiveness in integrating safety during design. On one side, it slows down the professional development of junior safety engineers, while on the other side it creates a sectarian attitude that isolates safety engineers from the rest of the project team. To speed up professional development, bridge the gap within the team, and prevent hampered communication and missed feedback, the entire project team needs to acquire and develop a shared culture of space safety principles and techniques.The second edition of Safety Design for Space Systems continues to address these issues with substantial updates to chapters such as battery safety, life support systems, robotic systems safety, and fire safety. This book also features new chapters on crew survivability design and nuclear space systems safety. Finally, the discussion of human rating concepts, safety-by-design principles, and safety management practices have also been revised and improved. With contributions from leading experts worldwide, this second edition represents an essential educational resource and reference tool for engineers and managers working on space projects. - Provides basic multidisciplinary knowledge on space systems safety design - Addresses how space safety engineering and management can be implemented in practice - Includes new chapters on crew survivability design and nuclear space systems safety - Fully revised and updated to reflect the latest developments in the field

Book Description
This report details the use of a modal emissions model to estimate the relative emissions of CO due to changes in vehicle operating characteristics on urban roadways. The Davis Institute for Transportation Studies Emissions Model (DITSEM) was selected to demonstrate the emissions characteristics of different freeway operating conditions. Instrumented vehicle data collected in Houston, Texas provides a set of operating parameters for which CO emissions are estimated. These estimates are calculated for different times of the day on the same facility to determine the relative emissions levels from a representative vehicle traveling on the freeway. The research team examined 10 samples along three roadways (two freeways, and one arterial). Implausible results were found in data exhibiting high average speeds (>60 mph) where average emissions rates were higher than those on the same roadway under congested conditions. This led to several conclusions of which the most important was that the DITSEM model not be used with samples where the percent of the driving cycle greater than 60 mph 2/sec exceeds 9%. This limit represents the highest value from which the model was derived for this variable. In addition, it is noted that the speed instrumentation was not able to provide sufficient precision for meaningful analysis with the available data.

Book Description
ACRP Research Report 180 provides guidance with regard to accounting for ground access vehicle (GAV) activity in airport emissions studies. This guidance will be of particular interest to airport environmental and transportation planners, air quality modelers, and regulatory agencies desiring clarity and consistency with regard to determining data needs based on study objectives and for collecting the data in an accurate, cost-effective manner.
