Some people wonder why countries spend millions of dollars on space projects.
有些人不明白為什么國家要在太空項目上投入數百萬美元。
They want to know how space research helps people on earth.
他們想知道太空項目如何幫助到地球上的人們。
Actually, space technology helps people on earth every day.
實際上，太空技術每天都在幫助地球上的人們。
This is called "spin-off technology".
它被稱為"衍生技術"。
Spin-off technology is space technology that is now used on earth.
衍生技術是目前應用到地球上的航天工程技術。
In early space programs, such as the Apollo missions of the 1960s and 1970s,
從20世紀60年代和70年代的阿波羅計劃等早期太空計劃，
and in the Space Shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space.
到如今的航天飛機計劃，科學家們為航天員研發了在月球上和太空中使用的物品。
We now use some of these objects every day.
其中有些物品我們如今每天都在使用。
For example, we have Quartz Crystal clocks and watches accurate to within one minute a year.
例如，我們使用的每年誤差不超過1分鐘的石英水晶鐘表和手表。
We purify the water we drink with the water filter designed for the astronauts'use in space.
我們用濾水器凈化飲用水，而濾水器是專為航天員在太空中使用而設計的。
The cordless, hand-held tools we use in our homes,
我們家中所使用的無線手提工具，
such as vacuum cleaners, flashlights, drills came from the technology of these early space programs.
比如真空吸塵器、手電筒和鉆頭，都來自于早期太空項目里的技術。
On cold winter days, we can stay warm with battery-operated gloves and socks, and especially made coats and jackets.
在寒冷的冬天，我們可以用電池供電的手套和襪子和特殊設計的外套夾克來保暖。
All of these clothes are similar to the spacesuit designs
這些衣服的設計和宇航服的設計相似。
that kept astronauts comfortable in the temperatures of the moon, and are spin-offs from space technology.
宇航服是為了使航天員在月球的溫度下保持舒適。這些設計都是航天工程技術的衍生品。
These products are only a few examples of the many ways space technology helps us in our everyday lives.
這些產品僅僅是航天技術惠及我們日常生活方方面面的幾個例子。
No one knows how new spin-off technology from the International Space Station will help us in the future.
沒有人知道來自國際空間站的新的衍生技術未來會如何造福人類。
