Why should mankind explore space? Why should money, time and effort be spent

exploring

and

researching

something

with

so

few

apparent

benefits?

Why

should

resources be spent on space rather than on conditions and people on Earth? These are

questions that, understandably, are very often asked.

Perhaps the best answer lies in our genetic makeup(

基因构成

) as human beings.

What drove our ancestors to move from the trees into the plains, and on into all

possible areas and environments? The wider the spread of a species, the better its

chance of survival. Perhaps the best reason for exploring space is this genetic

tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any

dangers in surrounding areas can be identified and prepared for. Without knowledge,

we may be completely destroyed by the danger. With knowledge, we can lessen its

effects.

Exploration also allows minerals and other potential (

潜在的

) resources to be

found. Even if we have no immediate need of them, they will perhaps be useful later.

Resources may be more than physical possessions. Knowledge or techniques have been

- 2 -

acquired

through

exploration.

The

techniques

may

have

medical

applications

which

can

improve the length or quality of our lives. We have already benefited from other

spin-offs

including

improvements

in

earthquake

prediction,

in

satellites

for

weather

forecasting

and

in

communications

systems.

Even

non-stick

pans

and

mirrored

sunglasses

are

by-products

(

副产品

) of

technological

developments

in

the

space,

the

chance to save ourselves might not exist.

While many resources are spent on what seems a small return, the exploration of

space allows

creative, brave

and

intelligent members

of our

species

to

focus

on what

may serve to save us. While space may hold many wonders and explanations of how the

universe was formed or how it works, it also holds dangers. The danger exists, but

knowledge can help human being to survive. Without the ability to reach out across

space, the chance to save ourselves might not exist.

While

Earth

is

the

only

planet

known

to

support

life,

surely

the

adaptive

ability

of

humans

would

allow

us

to

live

on

other

planets.

It

is

true

that

the

lifestyle

would

be different, but human life and cultures have adapted in the past and surely could

in the future.
