In 1987,,the first artificial satellite in the world was created and successfully lauched.In 2003,the NASA rover Spirit landed on Mars,.In 2013,Chsang e 3 Rover landed on the moon.In the latest years,most great powers all over the world has never stopped their step to explore space with a huge investment.Some people may wonder dose it really make any sense to spend billions of dollars on space exploration.The answer is definitely yes.Space expllorationi is exactly a good investment for the following five reasons.

1. It is rootly resulted in human beings thirst for knowledge about unknown things.Exploration is human beings natural interest and flying is human beings natural habbit.Though in the beginning of 2003,space shuttle Colombia wrecked.No matter succeed or fail,people are always eager to space exploration.The essential difference between humans and animals is that people keep thinking,exploring and developing.Confronted with questions like where did I come from and where should I go such ultimate philosophical questions,,we can not easily find answers in the real world then we may put our eyes to the space.

2. People can develop only by challenging unknown things.Thanks to space sxploration,the ecience technology in many other fileds is largely improved,such as meteorology,communication and GPS,HPC,micro electronics and many other fields.Even the medical

detecting and monitoring equipment,MMR are originated from the space exploration.If there is no space exploration,we can live without mobile phones,microwave oven and many other thingd.To the general public,,space exploration seems like a thing far away from our daily life.But in fact,,space exploration is closely related to our everyday life.It provides us with new products and technology.

3. Space is human beings future.Our civilization is developed by the consumption of resources.With the resource on earth exhausting,,our speed of resource consumption becomes faster and faster.One day we should use up all resource and we can only ask for resource from space..The resource in the universe are in great abundance.Earth is humans cradle,but we can not be rstrivted to the cradle,but to walk out of the cradle.

4. Space exploration is closely related with national defense security.Missilery largely depends on space exploration and satellite technology is vital to strategic reconnaissance ability.And it will also accelerate our nations technology level.
