People usually have divided opinions on whether space expedition, which costs a lot of money, is worth exploring. Through space research, people can have a chance to understand better about our universe and the Earth, while it takes tremendous amount of cash, which may result in a waste of money eventually.
When it comes to the advantage of space exploration, people can gain knowledge about the universe where we live in. By carrying out research about space, the birth of the Earth or the history of the universe will become clear, providing people with understanding of our origin and prediction about the future of the Earth. For example, Mars is one of the most popular subjects of space exploration because it is the most similar planet with the Earth, which means people can get some hints of the life in there later.
However, there are several drawbacks of space studies. Since space is an unexplored place, no one knows what happens in there. If there is an unpredictable accident in the spaceship sent to space, tremendous amount of money used for making the ship and fostering astronauts will become meaningless. Also, before exploring the outer space with a huge budget, governments should spend money on more urgent issues such as social health care. There are many people who lack basic things like food or shelter, so governments must deal with these issues first.
In conclusion, space has been a subject of curiosity for humankind since the discovery of its existence. Through space exploration, people gain a number of useful information for understanding our universe. However, it takes a huge amount of money, which can be used in other social matters.
