These programs are as follows: Smart Lander and Long-range Rover programs, sample return and Scout missions. NASA is promising to launch its first rover as early as 2009. Launching of this portable science laboratory would give the scientists a closer access to Mars’ surface. NASA also proposes to create a new line of small “Scout” missions whose launch is planned for 2007 already. In the framework of this mission, which might involve “airborne vehicles or small landers” (NASA), new panoramas would be opened for us. And the third program planned to be undertaken in the second decade of the century is the return mission of bringing Martian rocks and soil to Earth. This mission will help us study the actual essence of Mars and will make a great scientific break-through. (Mars exploration program)

This essay is intended to draw a comprehensive picture of life on Earth, the human journey, and energy's role. The references that support this essay are usually to works written for non-scientists or those of modest academic achievement so that non-scientists can study the same works without needing specialized scientific training. I am trying to in a tiny fraction of the global population. . My hope is that the energy issue can become that tiny fraction's focus. Properly educated, that group might be able to help catalyze an energy effort that can overcome the obstacles. That envisioned group may help humanity in many ways, but my primary goal is manifesting those technologies in the public sphere in a way that nobody risks life or livelihood. I have seen too many wrecked and prematurely ended lives (, ) and plan to avoid those fates, for both myself and the group’s members.
After I first published this essay in September 2014, I read Paul Boyer's , which surveyed the reactions of Americans to dropping atom bombs on Japan. I read it in relation to my studies regarding the , but what struck me was how similar the reactions to the bombs were to how people view FE today. The primary difference, of course, is that everybody acknowledges that nuclear bombs exist and have been used, while almost nobody acknowledges today that FE technology exists, through , , or . Another obvious difference is that the first use of atomic energy was vaporizing a couple of cities. While the initial American reaction was celebratory and euphoric, it quickly became evident that the USA would not hold a monopoly on nuclear weapons forever, and fears of nuclear attack became part of the fabric of American consciousness, and by 1946, nearly half of Americans were amenable to the idea of a world government that could prevent a nuclear holocaust.

This essay has presented Earth’s many changing faces during its journey. Earth had molten beginnings, was , and may have . Later, and and . Earth experienced swings from to conditions as atmospheric gases dramatically changed, continents moved, and vast and of complex life played out on land and sea. But the changes happened over timescales of millions and billions of years, not hundreds. No climate scientist will deny that carbon dioxide traps infrared radiation and warms Earth’s atmosphere. The vented enough carbon dioxide into the atmosphere to create 200 million years of Greenhouse Earth conditions, when reptiles ruled Earth. Volcanism waned and around 150-to-100 mya. By 35 mya, and the Antarctic ice sheet began forming. Every paleoclimate study I have seen places greenhouse gas (and primarily carbon dioxide) concentrations as the primary determinant of global surface temperatures, after the Sun's radiation, but the Sun's output is considered to have been exceptionally stable and has risen slowly over the eons. , usually by accentuating the carbon dioxide with a positive feedback effect that may have reached runaway conditions at times.

Economics is the study of humanity’s material well-being, but humans have rarely thought past their immediate economic self-interest, even when the long-term prospects were obviously suicidal, such as today’s global energy paradigm. Because environmental issues affect humanity’s material well-being, they are economic in nature. As can be seen so far in this essay, there was little awareness or seeming caring in early civilizations whether they were destroying the very foundations of their civilizations. Even if they did not care how much other life forms suffered, they did not seem to realize that it also meant that those oppressed and exterminated organisms and wrecked environments would not provide much benefit to humanity in the future, especially energy, whether it was food or wood.

In 508 BCE, Athens entered its classical period, which lasted for nearly two centuries. In those two centuries, so much was invented by Greek philosophers and proto-scientists that it has been studied by scholars for thousands of years. One provocative question that scholars have posed is why the Industrial Revolution did not begin with the Greeks. The answer seems to be along the lines of Classic Greeks not having the social organization or sufficient history of technological innovation before wars and environmental destruction ended the Greek experiment. The achievements of Greece over the millennium of their intellectual fecundity are far too many to explore in this essay, but briefly, the Greeks invented: , , , the , a monetized economy, thought, such as , while developing other branches to unprecedented sophistication, and , which included the idea that . Long after the Classic Greek period was over, Hellenic intellectuals and inventors kept making innovations that had major impacts on later civilizations, such as Heron of Alexandria (or some other Greeks) inventing the and .
