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 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.
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 beings 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.
