why is it important to explore space


3) It brings about great discoveries From the thermal space blanket, used today by marathon runners at the end of races, to the portable vacuum cleaners we now have in our homes, space research has bequeathed surprising and pleasing innovations that we non-astronauts use every day. 4) It inspires younger generations You could either ask a child, Would you like to become an aeronautical engineer whose job it is to design a plane 20 per cent more efficient than the previous model?. Or you could ask, Would you like to become an aeronautical engineer whose job it is to design a spaceship that could fly to Mars?. Guess which question is more likely to inspire him or her to study and dream of achieving great things? 5) We need new raw materials There s been much talk of private companies, intent on extracting raw materials from asteroids, turning space material into ready cash. But there s no need to go so far as asteroids in the search for the raw materials we need on Earth. The moon, for example, is rich in helium-3, a very rare isotope on Earth that is used mostly for nuclear-fusion research. On the moon, you can also find europium and tantalum, elements always needed in the field of electronics and in the construction of solar panels. 6) It guarantees us greater world security The political role of surveillance satellites in studying the military movements of countries is well-known.


Securing a seat in the front row of space research allows military superpowers like the US, Russia and China to monitor the moves of rival countries and prevent, for instance, the race for the possession of a вsliceв of space and the resources it offers (think of the moon, for example). The US, the Soviet Union and China signed an international agreement in 1967, which prevents any claims of sovereignty upon a portion of outer space, and prohibits the placing of nuclear arms in the Earth s orbit, on the moon, or on other celestial bodies. 7) It sets an example of peaceful collaboration Many positive collaborations between nations emerge from space exploration, from the subdivision of costs to the sharing of technological resources that guarantee the safety of astronauts (think of the Russian shuttles that have taken even Americans into space). To be sure, international political events can impact on the long-term plans of various space agencies, but, so far, they haven t managed to undermine the friendship and group spirit on board the ISS. 8) It could answer that eternal question are we alone in the universe?

So far, the Kepler space telescope has unveiled a long list of other Earths beyond our solar system, situated in inhabitable belts around their respective stars. They are all potentially hospitable for life. In 2018, the James Webb space telescope will take on the mantle of chief hunter of worlds, and it could perhaps find an Earth-twin able to host forms of alien life. 9) It responds to an age-old desire There are indeed practical and economic reasons to explore space, as outlined above. But there are other, less overtly rational reasons, too. For a start, there is a motive underpinning peopleвs willingness to risk their lives exploring space: that is, the thirst for exploration, which, for time immemorial, has characterised humanity. Without this thirst, our ancestors would never have left Africa, let alone set foot on the moon. And we would never have gone to a comet, as last yearвs Rosetta mission did, to search for the origins of life. 10) We need to colonise space There s been enough damage done to this planet. Very soon, if we want the human race to survive, we will need to colonise another planet.

According to a 2012 UN Programme for the Environment report, the Earth can sustain a population of eight-to-16 billion at most. Considering that we have already surpassed seven billion, before long we might have to look at new worlds on which to establish ourselves. It is a search that has already begun.

Satellite technology has revolutionized our planet in almost every way. Weather satellites help us track developing hurricanes, allowing meteorologists to warn people days in advance. That saves thousands of lives. Communication satellites allow us instant access to information all over the world using radio, television, and phones. Some people credit in part the fall of the Soviet Union to ease of information access; the people in those countries saw what the rest of the world was doing, accelerating the process of reform. GPS satellites allow us to track ships, airplanes, and even people who may be lost or in need of help.
