I personal predict that within the next 25 years, space travel will either become possible, or very near close, private parties (Sir Richard Branson, etc.,) are striving hard to make that vision a reality as soon as possible. Since the days of Sputnik, the race has begun again!http://www.waaytv.com/news/local/story/Huntsville-Space-Professionals-Look-to-Commercial/Fl_t2yNVa0y1XQjZC2X4gw.cspx
Within the next 25 years, with these private companies emerging and putting in their bids for space travel, NASA will have to become a governing agency much like the FAA & DOT. They will have to become the regulator of the industry and ensure that all participants in space travel are held to the highest standards.
I can envision private companies taking on the roles of current airlines, consulting firms, safety companies, etc. I think that space travel will mirror the aviation world as we know it. Especially since Airline mega-monster VIRGIN ATLANTIC, Inc. is one of the leading companies in the race to space. http://www.virgingalactic.com/news/
With the new ISS space station fully operational, life in space is becoming the new query in many people’s mind. “What if we could live in space like they do in the movies?” Before the purpose was to explore the other planets, and our solar system. Now it could possibly be viewed as the newest fad or luxury.
It is my belief, that it would be more of a cost than a benefit. We would have to devote trust of our lives to environmental systems, like life support on “Star Trek”. We all know that there is no oxygen in space, and it’s so cold, that exposure triggers almost instant death. And think of all the $$$ that would be required to make a new world in space, compared to what we already have spent on making the world what it is today?
Career wise, I think it’s almost a no-brainer that Aviation-based careers would become the new “gold”. And it would open further opportunities to scientist and pave the way for new inventions, and endeavors for years to come.
