Donald Rapp - Personal Website
I have 50 years of post-doctoral experience. I am a true generalist. I am 50% scientist and 50% engineer. I have worked on an extremely wide variety of technical problems over the years and I have broad knowledge of things technical. I have a solid grounding in chemistry and physics and did fundamental work in these sciences for many years. In the second half of my career I worked on more applied problems, particularly in space technology and space mission design. I am an expert in requirements, architectures and transportation systems for space missions, with particular emphasis on impact of in situ resource utilization, and water resources. I have surveyed the wide field of global climate change energy and I am familiar with the entire literature of climatology. I am known far and wide in the NASA community as for my abilities to plan, organize and lead studies of broad technical systems. My services have been often sought in writing and reviewing major proposals for space ventures.

A human mission to Mars would be the pinnacle of Solar System exploration, representing not only an inspiring engineering achievement, but also the creation of a new era of expansion of humanity into space. Although NASA and others have developed scenarios for how such a mission might be carried out, many of the assumptions were optimistic and many details were left out. Because once embarked to Mars, there is no return to Earth for about 2.7 years, every system must be exquisitely reliable.
This book takes a critical view of the requirements for human missions to Mars from an engineering perspective. It discusses in detail all the technologies that need to be developed and demonstrated and examines the full range of elements critical to such missions, including recycling of life support consumables, radiation effects and shielding, aero-assisted orbit insertion and entry descent and landing amongst much else. The initial mass in low Earth orbit is used as a guide for Mission feasibility.
Lavishly illustrated, Human Missions to Mars is a highly readable yet realistic view of the possible future of the exploration of the Red Planet. For the first time it brings together a wide range of material currently fragmented in the literature, and presents a cogent argument against the overly-optimistic forecasts promulgated by NASA, the Mars Society and others. At the same time, it presents a plan to establish the technical basis for a credible human mission to Mars.

Series: Springer Praxis Books Environmental Sciences
by Donald Rapp, hardback, 410 pages, March 2008 ISBN: 978-3-540-76586-8; two 8-page color sections Second edition 2010 Third edition 2013
In ASSESSING CLIMATE CHANGE Donald Rapp has investigated a large body of scientific data relevant to climate change, approaching each element with necessary (but neutral) scientific skepticism. The chapters of the book attempt to answer a number of essential questions in relation to global warming and climate change. He begins by showing how the earth’s climate has varied in the past, discussing ice ages, the Holocene period since the end of the last ice age, particularly during the past 1000 years. He investigates the reliability of "proxies" for historical temperatures and assesses the hockey stick version of global temperatures for the past millennium. To do this effectively he looks carefully at how well near surface temperatures of land and ocean on earth have been monitored during the past 100 years or more, and looks at the utility and significance of a single global average temperature.
Topics such as the variability of the Sun and the Earth’s heat balance are discussed in considerable detail. The author also investigates how the current global warming trend compares with past fluctuations in earth’s climate and what is the likelihood that the warming trend we are experiencing now is primarily just another in a series of natural climate fluctuations as opposed to a direct result of human activities. A key factor in understanding what may happen in the future is to examine the credibility of the global climate models which claim that greenhouse gasses produce most of the temperature rise of the 20th Century, and forecast much greater impacts in the century ahead.
Finally, the book considers future global energy requirements, fossil fuel usage and carbon dioxide production, public policy relating to global warming, and agreements such as the Kyoto Protocol.

|Bubbles, Booms and Busts - The Rise and Fall of Financial Markets
by Donald Rapp, about 300 pages, published June, 2009 by Springer-Verlag/Copernicus Books
This book builds upon previous discussions of booms and busts, particularly those of John Kenneth Galbraith. The first part of the book describes that stages of buildup and collapse of financial manias in terms of human element. These are divided into speculations, bootstraps and swindles. Discussions are provided on the distribution of wealth in the US, the nature of inflation, the role of the Federal Reserve in promoting bubbles, tax history and policies, debt (federal, state, municipal and personal), banks and banking, pension plans, and valuation of common stock.
The book then goes on to describe specific boom/bubble/bust cycles with many examples including the Florida land boom of the 1920s, the bull market of the late 1920s, the depression of the 1930s, the savings and loan scandals of the 1980s, the great bull stock market of 1982 to 1995, the crash of 1987, the dot.com mania, the sub-prime fiasco of 2002-2007, and a number of other bubbles and swindles.
|Ice Ages and Interglacials
by Donald Rapp
This book studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth’s climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ice ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years).
The second edition of this book has been completely updated. It studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth's climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ices ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years).

|The Climate Debate
Most published books are one-sided in the climate debate between alarmists and skeptics. My book on the climate debate presents both sides of the debate with considerable technical detail and weighs the supporting evidence. It is found that in general, the data in climatology are very sparse and noisy. Yet climatologists seem willing to draw a dollar’s worth of conclusions from a penny’s worth of data. The sad truth is that we don’t really have good answers to the questions raised in the climate debate. My book shows why this is so. This new edition includes hundreds of references not included in the original version, and the book is expanded by more than 100 pages.
|Use of Extraterrestrial Resources for Human Space Missions to Moon or Mars (Springer Praxis Books / Astronautical Engineering) [Hardcover]
This book carries out approximate estimates of the costs of implementing ISRU on the Moon and Mars. It is found that no ISRU process on the Moon has much merit. ISRU on Mars can save a great deal of mass, but there is a significant cost in prospecting for resources and validating ISRU concepts. Mars ISRU might have merit, but not enough data are available to be certain. In addition, this book provides a detailed review of various ISRU technologies. This includes three approaches for Mars ISRU based on processing only the atmosphere: solid oxide electrolysis, reverse water gas shift reaction (RWGS), and absorbing water vapor directly from the atmosphere. It is not clear that any of these technologies are viable although the RWGS seems to have the best chance. An approach for combining hydrogen with the atmospheric resource is chemically very viable, but hydrogen is needed on Mars. This can be approached by bringing hydrogen from Earth or obtaining water from near-surface water deposits in the soil. Bringing hydrogen from Earth is problematic, so mining the regolith to obtain water seems to be the only way to go. This will require a sizable campaign to locate and validate useable water resources. Technologies for lunar ISRU are also reviewed, even though none of them provide significant benefits to near-term lunar missions. These include oxygen from lunar regolith, solar wind volatiles from regolith, and extraction of polar ice from permanently shaded craters.
