Question

    Studying the moon is not just about exploring (探索) space. By studying the moon, scientists have created new technologies (科技). Later, they used these technologies to create some cool inventions. These inventions help us live better lives. What are they? Let’s find out!

Nike Air

In 1960s, NASA scientists used a special material (材料) to make astronauts’ helmets (头盔). This material makes the helmets lighter. Later, scientist used this material to make shoes. This is the Nike Air. Such shoes are good for running. They are light and stable (稳定的).

Vacuum cleaner

Is there a vacuum cleaner in your home? It uses space technology. During the 1960s, NASA made a kind of drill (电钻). Astronauts used the drill to take rocks from the moon. Later, scientists used this technology to make vacuum cleaners.

Firefighters’ breathing systems

Astronauts may have some emergencies (紧急情况) in space. For example, they might find it hard to breathe (呼吸) in their spacesuits. Scientists made a special breathing system to solve this problem. Firefighters on Earth still use this same breathing system.

Plant study

One day, we may go to the moon. What would we eat there? Scientists have studied plants. They want to grow plants in liquid (液体) instead of soil. Plants can be a kind of food. They can also provide oxygen (氧气) and water. Some day, we may use them to make food on Earth.
