The

Future

of

Space

In the movies, humans often explore deep space.

They travel faster than the speed of light. Landing

on strange planets and meeting aliens is all in a

days work.

In real life, technology is limited. But scientists

are searching for habitable planets. They are

looking for signs of intelligent life . And they are

working on making space travel much faster so we

can travel greater distances. But three things need

to happen before we can travel into deep space as

they do in the movies. First, we need to travel much

faster. But we cant go far without fuel. And fuel

is heavy. Somehow, we must power long-distance

voyages without running out of fuel. And finally,

we need to power the space vehicle once its in

space. Today, scientists are focused on making

breakthroughs on these three problems.

What breakthroughs in

technology will help us

travel deeper into space?

What new technologies

will help us build better

space vehicles?

What might we find as we

travel into space in the

22nd century?

Its hard to say what will happen. Not even the

National Aeronautics and Space Administration

(NASA) plans more than years ahead! But all the

ideas in this book are based on real science. Life today

is very different than it was a hundred years ago. And

its hard to know what will happen in the next hundred

years. One thing is certain. Much of what is science

fiction today will be reality tomorrow.

How Far

Weve Gone

The space probe Voyager

has traveled farther than any

other spacecraft from Earth.

It took over years for it

to reach the edge of our

solar system.

Voyager

How Far is Far?

A light-year is equal to the distance light

travels in one year, about 5.8 trillion miles.

Proxima Centauri

4.2 light-years away from Earth

moon

0.0000000406

light-years from

the sun

sun

0.000016 light-years from Earth

New Technology

New inventions can be simple or complex. But the

best ones make our lives easier. They allow us to do

things we couldnt do before. Today, we no longer rely

solely on telescopes to learn about space. Now, we can

send rockets into space. We can land robots on distant

planets. Humans can live on space stations. And this is

just the beginning.

New technology comes from new ideas. Nearly every

invention requires creativity. Mistakes will be made.

But there will also be successes. Scientists are merging

current technology with imagination. They plan to invent

technology that is out of this world!

Futurists

Futurists are people who

take what we know today

and try to imagine where it

might lead in the future. Not

everything they come up with

happens, of course. But their

ideas often guide research

going forward.

Past Predictions

In the past, futurists predicted that by today we

would have:

flying cars

computers in every home

time machines

electronic money

cities in the sky

shopping by computer

artificial human organs

intelligence pills

Which of their predictions have come true so far?
