Answer 1

There are several different ways to get into space, but we currently only have tried one of them.

The most common way to get into space is using a rocket. As mentioned before, this is very expensive (about $10,000 per pound). Since I weight almost 200 pounds, it would cost $2,000,000 just to get me into orbit. Other people say that the commericial sector can do this cheaper (such as Space Ship One - Burt Raton), but they haven't gone into orbit, just a simple up and down flight, only reaching 3,000 mph (17,500 mph is needed for orbit) and then you need a way to get back without burning up in the atomosphere. Every time you add something else to the ship, it gets heavier and makes it more expensive to get going fast.

Another way to go up to space that hasn't been tried yet, but many of the big companies (Lockheed and Boeing) are helping NASA work on a Scramjet. A scramjet works by scooping up the oxygen in the atomosphere and squeezing it while adding hydrogen and burning it. Since it doesn't require the oxygen to be carried, it can make the spacecraft/plane much lighter and get it going about Mach 10 (I think that's around 7,500 mph). Then conventional rockets (but smaller) can be used to boost it the remaining distance if you are trying to get into low earth orbit. Or if you are using it as a passenger jet, you don't need the rockets and can just cruise around the globe. So a flight to opposite side of the world would only take a couple hours. To get to low Earth orbit, might cost as little as $1000 per pound, so I'd only need $200,000 for that flight to get me up there.

The last method I know of seems a bit like science fiction, but actually might be the best approach yet. The Space Elevator is simply attaching a really strong ribbon about 3 feet wide to the Earth and extending it out 64,000 miles (if I remember correctly). Then a "climber" (kind of like a car) would travel up and down the ribbon. Up until recently there wasn't any material strong enough to do this, but in 1991 carbon nanotubes were discovered and are strong and light enough to do the job. But building the ribbon is still a difficulty. But the mission plan looks pretty solid and the expected cost to deploy the ribbon and use it is about $11 billion. They expect the cost to go down to $100 per pound, which would mean I only need $20,000 to get into low earth orbit. But what's even better is that the space elevator can actually put me further out to the La Grange points between the Earth and Moon, or actually put me on course to land on the moon. There are still plenty of people that think this is somewhat crazy, but having reviewed lots of material on it, I believe that the planners have thought of nearly everything and that it seems worth it, especially for the long term pay-off and safety.

Answer 2

I believe we have the technology to do such things. However the things that stop us is the incredible amount of stupidity of having to be "first" with any discovery.

It is ironic... our parents teach us that it is good to share (and punish us if we don't)... but when it comes to research, science, and technology it is considered a terrible crime to share technology and research with another scientist (worse if they are in different countries).

The other thing that halts us is our economy. The amount of money "needed" for this sort of project is extremely high. The value of everything has shot up to where it is almost impossible to live a healthy life, yet the returns (paychecks and similar) have not changed with this rise.

It's like this... when I was 10 I could take a doller and go buy myself a can of coke and a small bag of chips for myself and a friend, and still have change. 30 years later (today) that same dollar won't even buy either the small bag of chips or the can of coke (both being now over a dollar in cost).

Answer 3

Currently it cost about $10,000/ pound to put something into orbit. We can put as much as we want into orbit the big problem is money. With out that, nothing goes into space, nothing goes to the moon.

That is NASA's problem right now. Politicians think NASA can do anything regardless of their budget.

Answer 4

We have the technology, but not enough good spellers or grammarians. That's the best way.

Answer 5

Yes! all you need is a realy BIG sling shot and a cyote to help you set it up!

Answer 6

keep away from cotote coz road runner faster, use ACME. com
