		<description>NUCLEAR FUSION PARTICLE ENVIRONMENT

Just entering the microcosm of atom matter where it is able to absorb and emit energy, still having the possibility to obtain energy from the mass of matter which can be found everywhere.
Interestingly, E = mc²  does not contain any reference to a particular substance, but there is no need, for one gram of air, water or gram per gram of cosmic particles, is also a gram of mass.
So our new role is important to release any material amount of energy in mass that surrounds us and which we use or adapt to the devices and equipment built until now

Why this huge energy consumption?
To overcome the planet&#039;s gravitational field and allow a ship to travel in outer space
All bodies around the globe are attracted to Earth, the force of attraction called the gravity and acceleration with which these bodies attracted into the gravitational field is called gravitational acceleration g = 9.81 m/ s ².
Speed needed to escape Earth cosmic ship is 11000 m / s  and can be done with an amount of energy of 2,400 tons of fuel
Escape speed from Earth&#039;s surface is called the second cosmic speed.
With this speed of a ship lifts off from Earth&#039;s surface and escapes the planet&#039;s gravitational field.
Gravitational acceleration surface  of Mars is g = 3.75 m / s ² and have an escape speed of 5100 m / s which is equivalent to a fuel quantity of 1055 tons
For a trip to outer space or on Mars was built a Kennedy Space Center, a spaceship and made available energy 2400 tons of fuel - liquid oxygen and to overcome the gravitational field of Mars that has g = 3.75 m / s ²  and to return to Earth we need a space center, a spaceship and an energy of over 1055 tones of fuel - liquid oxygen

Stephen Hawking&#039;s Warning: Abandon Earth—Or Face Extinction
Let&#039;s face it: The planet is heating up, Earth&#039;s population is expanding at an exponential rate, and the the natural resources vital to our survival are running out faster than we can replace them with sustainable alternatives.
So, according to famed theoretical physicist Stephen Hawking, it&#039;s time to free ourselves from Mother Earth. 
&quot;I believe that the long-term future of the human race must be in space,&quot; 
&quot;It will be difficult enough to avoid disaster on planet Earth in the next hundred years, let alone the next thousand, or million. The human race shouldn&#039;t have all its eggs in one basket, or on one planet. Let&#039;s hope we can avoid dropping the basket until we have spread the load.&quot; 
Solution to travel in outer space with the same ease as we do by car, bus, streetcar, subway, train, boat or plane is:

		<description>Hey,

I&#039;ve searched a bit arround, it is sooo boring here(!), 
found this page and enjoyed a lot!

This is such a great sentence &quot;To me, NASA has always been the organization that paves the way. We should even be giving more money to NASA. They’re the ones, as a government agency, that can afford look into innovative technologies, groundbreaking technologies, things that push the limits of what we know, new types of propulsion, new ways of getting into space.&quot; 

I think, I&#039;ll set up something to this post at my small &lt;a href=&quot;http://www.zummondfliegen.de&quot; rel=&quot;nofollow&quot;&gt;zummondfliegen&lt;/a&gt; Blog, because this could be interessting for my readers, too!

Have a nice day :)</description>

		<description>Getit Rightplease?

Are you serious? You quote: &quot;So first, the SpaceX Falcon 9 LV and Dragon capsule have been designed as man rated from day one, &quot;

How can the Falcon9 be designed for &#039;man rating&#039; when SpaceX doesn&#039;t even have the man-rating requirements????</description>

		<description>It is said that those who don`t learn from history are doomed to repeat it.
At last some people are beginning to understand what Obama`s plan is all about ie. Phill Plait, Buzz Aldrin, Ferris Valyn, Charlie Bolden.  It is about saving human spaceflight not destroying it. Constellation would have would have ended it.
   You know when Apollo ended I was very disappointed and thought it was the end of human spaceflight. But the people who ended it were right not I. A cheaper way had to be found and the Shuttle was never it. I recently read an article on the solid rockets which was an eye opener. The refurbishing of these rockets was very labor intensive such that it is doubtful that they actually saved any money. The rest of it was just as expensive: A huge tank with which nothing could be done and which damaged tiles from ice build up. Verticle Intergration, a multimillion dollar crawler to get it out to site. Too expensive.
  SpaceX does things different: Horizontal integration, transporter erector, launch in an hour (not months), eventual reusability. The big cost plus boys, Boeing and Lockheed Martin, are finally going to have to do something to bring down costs or loose it all to SpaceX.
  To Jorge Salazar: I`ve surprised with the reaction of some people. It seems they`re not interested in space and ensuring that it happens or new ideas. They just choose sides without thought. You know I became interested in space when I was 8 years old and at 66 years of age I find it just as exciting as when I was 8.
Phil Plait has it all right but I hope he`s wrong about the compromising. I say Charlie forget about the heavy lifter. Leave that up to commercial space too. Delta has a heavy lifter and SpaceX has one on the drawing board. I think it time to think about a Real Space Ship one that never lands on Earth but stays in orbit where is refuelled and serviced. Going from Earth to Mars is a waste of money. Going from Earth Orbit to Mars is the way to go. This Space Ship would use Vasimr Ion engines to shorten travel times and Chemical rockets to initiate it`s voyage. Astronauts on their way to Mars would use commercial rocket to get to the space station transfer to their Real Space Ship equiped with a rotating boom for artificial gravity and away they go.

		<description>Just a few corrections that a 5 minute trip to Wikipedia or the SpaceX web site could have made un-needed.  I think it&#039;s great to have a discussion and share opinions, but ignoring facts either on purpose or out of laziness is not helpful to anyone.

So first, the SpaceX Falcon 9 LV and Dragon capsule have been designed as man rated from day one, and they comply with every NASA standard for human rating launch vehicles that is available.  Secondly, the Falcon 1 has had 5 flights, the first 3 did not reach a stable orbit, true, but they all had increasing levels of success which I feel is pretty reasonable for a brand new rocket from a brand new company.  The 4th and 5th flights of the falcon 1 were successful, so it seems like they have a pretty good design at this point although more flights would add to the confidence level.

Judging by the last update on the SpaceX web site, the first Falcon 9 launch should be sometime in the next month or two, so calling them &quot;nowhere near&quot; resupply of the ISS doesn&#039;t sound like the correct characterisation.</description>

		<description>Going commercial is good; going commercial via FLEX-UP is bad. Worse than bad it’s an outright OMG distraction and out right national tragedy! VSE is the key to robust focused future. We could have done VSE commercial we didn&#039;t have to chuck it all with the look but don&#039;t touch build but don&#039;t fly FLEX-UP. We just handed the high ground to the Chinese. ISS is a billion dollar relic of a blunder. A cluster of little tin cans. We&#039;ve been doing weightless LEO research for forty years first Mir then ISS look what it got us...nothing. VSE was intended to break this go no where cycle. FLEX-UP puts right back in it only now commercial is sucked into the black hole with NASA.</description>

		<description>Phil is exactly right about NASA&#039;s role. They developed the technology to put humans in space back in the 60s. The next logical step would have been to hand that off to private industry to turn into spaceliners. Instead, NASA wanted to protect their Apollo workforce, so they sold us the Space Shuttle. They promised a system that would fly weekly at a cost of $100 per pound to orbit. This resulted in the decimation of the space launch industry. Only after the Challenger accident did we start to look at commercial alternatives, and we&#039;ve been playing catch-up with the rest of the world ever since.

We cancelled Apollo simply because we could not afford it. We would have had to cancel Constellation eventually for the same reason. Better to do it now when we still have a chance to invest in the technologies that will make a real difference later.</description>

		<description>If Obama were such a big fan of privatization, he wouldn&#039;t have nationalized banks and automobile companies, and wouldn&#039;t have tried to nationalize health care.  Space exploration is not a priority for this president, and it&#039;s fascinating to watch even brilliant minds such as Phil&#039;s failing to get beyond their political bias.</description>
