Donald A. Rapp

Donald Rapp has a Ph.D from the University of California and over 60 years of technical research experience. He was a full professor at the University of Texas and spent over 30 years at Caltech's Jet Propulsion Laboratory. In his early career he worked in chemical physics, producing a dozen citation classics with up to a thousand citations, and textbooks on quantum mechanics and statistical mechanics. Later, he worked on spacecraft technology leading to his book "Human Missions to Mars". Since about 2006 he has worked mainly on climate change, ice ages and human missions to Mars. His positions on many key issues are contrary to mainstream trends. In particular, he is highly doubtful that life ever existed on Mars and thinks the NASA Mars Program is a boondoggle. He is also skeptical of alarmist claims regarding the dangers of global warming but he is concerned about rising CO2. At age 88, he is still going strong with a new book coming out in February 2023.
