Breakthrough

Breakthrough is a very difficult topic, luckily, in reading class, there is also a similar work. Then I don't need to think too much and I still have enough information.

The most contributed person I want to introduce is Robert Goddard, was the American scientist. I don’t know whether he is very famous or not, but he is known as the father of modern rocket propulsion, the inventor of the liquid-fueled rockets in 1909 and a control mechanism for rocket apparatus. He is contributed because his invention helps humans to have a chance to go to space. In the past, the problem of engine and fuel were the main problems but he invented liquid- fueled rocket, this brings the exploration to the space a big step forward. After people can go to space, they can build space station, which help some experiments and people to detect the space. People can detect the weather more accurate because we have satellites in the space. People can have information from other countries because the satellites receive and send different messages in and out. People have lots of advantages because Robert Goddard has invented liquid-fueled rockets to bring people and equipments to the space.

I really think that he is a great person because his invention really help in different areas. Many people can get advantages from his invention.
