Don't Pack Your Things Even If We Found Another Planet Like Ours.

According to the Office of Management and Budget and the Air Force Almanac, when measured in real terms (adjusted for inflation), the figure is $790.0 billion, or an average of $15.818 billion dollars per year over its fifty year history (NASA's 2011 budget is on a continuing resolution of the 2010 budget at $18.724 billion

'Super-Earth,' 1 of 50 Newfound Alien Planets, Could Potentially Support Life
The potentially habitable super-Earth, officially called HD 85512 b, is estimated to be only 3.6 times more massive than Earth, and its parent star is located about 35 light-years away, making it relatively nearby. HD 85512 b was found to orbit at the edge of its star's habitable zone, which is a narrow region in which the distance is just right that liquid water could exist given the right conditions


Forget cost, political will and all the other variables — simply obtaining enough energy will take until 2196, according to Marc Millis, former head of NASA's Breakthrough Propulsion Physics Project and founder of the Tau Zero Foundation, which supports interstellar travel research.

Millis did plenty of extrapolating to reach this conclusion, which he presented at an astronomy meeting in Prague last fall and posted to the physics archive this week. He crunched 27 years of data on energy trends, mission energy requirements, individual energy use and even societal priorities, and chose two possible trips: An aimless interstellar colony ship, and a 75-year-long mission to Alpha Centauri.

Millis examined the energy required to launch the space shuttle during the past 30 years, which is a fraction of the nation’s total available energy. He assumes the same ratio will hold for interstellar flight, as
Technology Review’s arXiv blog explains.

For a 500-person ship on a one-way journey, Millis figures you would need at least an exajoule — that’s 1018 joules — which is just a little bit less than all the energy consumed by the entire world in one year. For an unmanned ship destined for Alpha Centauri, you would actually need more energy, because you’d want to slow it down upon arrival at our nearest neighboring star. This would require 1019 joules. Even without accounting for fuel, the 500-passenger ship wouldn’t be able to launch until around 2200 at the earliest, and the A. Centauri probe won’t be ready until around 2500.

Millis’ math is actually more optimistic than other studies, which have suggested you would need 100 times the world’s total energy output to cover that distance.


I loved space since a little boy and still do; "However, Americans are struggling to pay bills find work and find alternate fuel and energy sources. Now is not the time to search for alien life in space or search for an inhabitable planet 20 to 50 light years away. until we can reach the speed of light; 186,282.397 Miles per second in a vacuum. Man will never reach the speed of light. To give you an idea how fast the speed of light is; If we could do the speed of light it would take us less that 2 seconds to reach the moon. "http://www.freerepublic.com/focus/f-chat/1655089/posts"

I think God created the speed of light to keep us earth people from reaching other inhabitable planets considering what we have done to "the earth. Americas infrastructure is crumbling in every State. In American some people what to spend billions of dollars to see what is out there.

I suggest since they humans came from the stars and are part of those atoms, wait till you die you will return to the stars and see everything.
