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

researching something with so few obvious 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(文明) 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(物质财产). Knowledge or techniques have been gained 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 industry!.

    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(适应的) 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.
