I do hope you are being sarcastic GHI,and you do know that we went to the moon.

 That being said,I dont think it will be in our lifetime that we send a human to mars..Takes about what,6 months or so to get there,by the time they do get there,neg G's will have affected strength,and I can just see someone stepping off the steps and breaking a leg..Not to mention the radiation which is flying through space to cause injury.

 I dont really see a space outpost on the moon either.I mean even IF they do get a plan together to start sending material up there to start constructing,it will be at least a century before it is completed.(READ AS) being able to stay for any extended length of time,6mos. to a year on the moon.And the cost..trillions

 I do appreciate the curiosity of men to want to accomplish these things,they are indeed grand,but reality has to step in and men have to give real,legitimate thought to just what it is they are saying...


 Mankind will never get out of the solar system,we just dont have the technology to go faster than the speed of light,it is impossible,it will never happen..And when you consider the nearest stars are thousands of light years away,well,here again is where reality steps in..

 I am ALL for exploring space with unmanned spacecraft,launching HUGE telescopes,experiments,etc..etc..


 But when it is all said and done.Space is just too hazardous to man.

  I love what the united states has accomplished in space,or for that matter any country curious enough to go up and take a look. But frankly,With all the redtape,the trillions of  dollars it would cost us,and not to mention the ability of man to really pollute just about everything we touch,I just cant see it.

 I know,I know,men were pessimistic about many things which have now come to pass,so please dont bother wasting your time typing that others also said such negative things about flying,or rockets going into space,or the horse being replaced,etc..etc..

  I actually am optimistic that we will find out many great things in working in space,and if it does come to pass,like people going to mars,I say well done.But it will not be done anytime soon.

the earth is flat, if you sail too far you will fall off the edge. That is if the sea monsters don't get you first.

Until I read this, I was going to say just that ;).  In fact I will anyway, just cause I feel like it :D.  But seriously, a few hundred years ago people probably could not possibly conceive how we would ever, EVER be able to fly.  Now flying is basically commonplace.  In those few hundred years, people haven't changed that much: we're more advanced technologically, but we're still short-sighted and rather closed-minded(sp?) about the future - just because we can't imagine a way to do something doesn't mean we can't do it.

Also, about your last paragraph: I agree completely lol.

BTW, Mars is just slightly bigger than the Moon and has similar gravity. People tend to think it's about like Earth, but it's very much NOT so. Wanna build a base? Pick 4 days vs 5 months and something that has been done vs something that hasn't....

Actually, Mars is about twice the size of the Moon, and has about twice the gravity.  And it has a substantial atmosphere, unlike the Moon.

Dragon,

Keep in mind propulsion models like electrodynamic drives that have high specific impulse but low thrust-to-weight ratios become much more feasible once you no longer have to worry about escaping atmosphere (highly efficient drives like electrodynamic/static don't have the thrust to escape atmosphere). The capability of greater fuel efficiency under these propulsion models would at least appear to lead to a quicker return on the investment than if conventional chemical rockets were used.

Dragon is correct.  Indisputable.

No i'm not sarcastic, i used to believe 100% in Moon landing, i still believe but i have some doubts,in last 5-10 years i've been watching and reading from  Mythbusters to Discovery magazines all kind of questions without answers about Moon landing. And about 11% of Americans don't believe it, why should i ?

In my opinion the first nut we need to crack is fully-reusable-single-stage-to-orbit. The most expensive part of any space flight is getting it off the ground and into orbit.

They had it figured out 30 years ago..  Why hasn't NASA acquired the technology and run with it?

"Actually, Mars is about twice the size of the Moon, and has about twice the gravity.  And it has a substantial atmosphere, unlike the Moon"

Okay, I am a tad uncareful, but Mars only has 1/10th of Earth's mass, 38% of the gravity, and 1% of the atmospheric pressure. Which is pretty...close to nothing. Size compares such:


Has a looong way to be earth like. And the moons?

Or rocks....escape velocity 40 and 20 km/h. Don't go too much on the trampolin there :D

Anyway, Mars is more interesting. It's just that it's that much further away, and not as big as most think, and.... there's soon 40 years since we were on the moon....

 Idiots are those who believe without searching,  i've seen those 19th century quality pics above in news this year. There was technology 30 years ago,to read "Pravda" newspaper in Red Square,through thick atmosphere from satelite orbiting 200 miles above, and this blurry pics taken by NASA  in 2009  prove what?

That you'd complain about us spending as much on a disposable moon probe as a spy satellite, if we did.

It proves we have satellites circling the earth and not the moon.

You need to do more research.  Alpha Centauri is 4.37 light years from our solar system.  Not "thousands of light years".   :rolleyes:

Additionally, there are physics models showing that warp drive IS a theoretical possibility, we just haven't reached that technological stage to be able to do it (subspace folding a'la Star Trek CAN work, we just don't have the technology to do so yet).
