CHAPTER 4 Spacecraft Propulsion

In 1798, Thomas Robert Malthus published “An Essay on the Principle of Population”. Malthus wrote that population will always increase in a geometric progression. This growth will quickly outrun the food supply and lead to famine, war, and ill health. He suggested that the poor should not be helped. This relief would only lead to the growth of a more excessive population. As Britain began a period of global colonization this philosophy was applied to the Irish. As predicted, in the short run, a famine ensued in Ireland. The Malthusian philosophy has, however, proved not to hold in the longer run. New lands were colonized and new methods of farming were developed. In 1968, Stanford Professor Paul R. Ehrlich followed through on the ideas of Malthus in his book “The Population Bomb”. Ehrlich predicted that the population would overtake the food supply by the late 1970s. A mass starvation would ensue. Ehrlich’s predictions seemed to be more plausible than those of Malthus. In the 1970s there were no new lands available on which to offload the excess population. Newly engineered crops and energy intensive methods of farming held off Ehrlich’s catastrophe. An unexpected drop in the birthrate also helped to fend off the impending disaster.

In the 1960s many scientists were invited to predict what the world would look like at the end of the 20th Century. Environmental scientist James Ephraim Lovelock made his prediction. In the end, Lovelock was the only one who got it right. He earned considerable credibility as a result of the accuracy of his prediction. He has now stated that population growth, along with an energy intensive lifestyle, have now defeated the earth’s capacity to control its chemical and physical environment. He claims, in the second half of the 21st Century that the only inhabitable places on Earth will be at the poles. He has suggested that we should, “Enjoy life while you can!” Australian researcher Graham Turner has recently taken another look at this issue within a MIT funded study. Turner has also found that the world is on track for a disaster. He has concluded that world will run out of natural resources. Oil will peak by 2030 and the demand for food and services will rise. The energy intensive farming and food supply system will fail.

In the early 1900s it was believed that the next frontier would be space. Future populations would live in huge spinning space wheels. The rain forests of Venus would be a tropical paradise. Canals could be built, if they were not already there, to bring water from the poles of Mars to its equatorial regions. These projections were wrong. Space travel proved to be extraordinarily difficult. So difficult that, at this moment, the United States has no manned space program.

The first probes to Venus measured its surface temperate and its atmospheric pressure. The surface of Venus roasts at 900 degrees Fahrenheit. That’s hot enough to melt lead. The pressure on the surface is ninety atmospheres. Every now and then the whole surface of Venus turns over in a massive volcanic eruption.
