Will living in offworld space colonies ever be embraced by mainstream humanity? Of course, no one can accurately predict how the future will unfold, but by examining today’s knowledge, we can create plausible scenarios of how space development might take place during the 21st Century.
We begin our glance into this future by focusing on how research efforts promise to improve healthcare, as we trek through the current decade and into the 2020s. Biotech scientists hope to strengthen our bodies and minds and protect us from disease, including many of the damaging effects of aging. Video.
And expected molecular nanotech advances during this same period will enable building products and materials inexpensively, mimicking the ways that biology creates plants, animals, and us. Experts predict that by building goods labor-free with low materials costs, nanotech will improve wealth worldwide. Video.
With concerns over health and failing economies removed from the spotlight, by mid-century, space exploration is expected to take center stage, as many future watchers believe that a new era of world peace and prosperity will be achieved as countries begin collaborative efforts to develop the high frontier.
Intelsat Vice President Richard Dalbello sees the space industry as the jewel of our economy. "It drives innovation, creates jobs, and positions us to begin mankind's greatest dream – to explore other worlds."
Potential benefits from space exploration include asteroid mining that could yield new minerals and ores, and some entrepreneurs are talking of harnessing solar power in space and beaming unlimited energy back to Earth, which some believe might one day replace our dependency on fossil fuels.
However, to live in space will be demanding for those willing to leave Earth for a radically different world. Mars' extreme weather and killer solar rays will require domed or underground habitats.
Alternatively, many forward thinkers believe we could reengineer the genes of these brave pioneers making them immune to the effects of Mars' harsh climate. Of course, gene therapies like these cannot be performed today, but as medical technologies advance, they may become possible in the future.
Although these solutions might sound more like fiction than science, if, as many future watchers predict, humanity is destined to one day leave this comfortable third rock from the sun and develop new worlds to call home, radical technologies like these could one day become the reality of our times.
If we are to become a space faring society, we must learn to survive in hostile places. Mars could be a key stepping stone along that path, an alien world, yet one that is not too difficult to reach from Earth.
Another issue in exploring space is the vast distances that have to be covered. This means that great speeds and/or very long travel times are needed. The time required to reach other solar systems using even the most futuristic of tomorrow's propulsion methods range from decades to thousands of years.
Officials at NASA's Glenn Research Center have been searching for different options to manage these vast distances. Arc Millis, former manager of the now inactive Breakthrough Propulsion Physics Project, believes that one day, humans will develop means to break the light-speed barrier with new energies; and could even harness wormholes for instant access to faraway regions of the universe. Article explains.
Throughout history, great nations have been at the forefront of the frontiers of their time. Britain became great in the 17th century through its exploration and mastery of the seas. America's greatness in the 20th century stemmed from its domination of the air. For future generations, the frontier will be space.
Will we evolve into a space-faring civilization? NASA Glenn's Geoffrey Landis believes that within 50 years, Earthlings will break the light-speed barrier and begin scattering its citizens throughout the galaxy. As we trek deeper into the future, aided by technologies we cannot even imagine today, it is easy for this writer to believe that by the end of the 22nd Century, more humans will live in space than on Earth.
And of course we will always keep in touch with these hearty space pioneers, because sharing experiences of life in a strange new world will enrich us all. Comments welcome.
