Some people
wonder why countries spend millions of dollars on space projects. They want to
know how space research helps people on Earth. Actually, space technology helps
people on Earth every day. This is called "spinoff technology".
Spinoff technology is space technology that is now used on Earth.
In early space
programs, such as the Apollo missions(任务) of the
1960s and 1970s, and in the space shuttle missions today, scientists developed
objects for the astronauts to use on the moon and in space. We now use some of
these objects every day. For example, we have Quartz clocks and watches with an
accuracy of one minute a year. We purify the water we drink with a water
filter(过滤器) designed for the astronauts' use in space.
The cordless, hand-held tools we use in our homes, such as cleaners,
flashlights, drills, and irons came from the technology of these early space
programs.
On cold winter
days, we can stay warm with battery - operated shoes and socks, and insulated(绝缘的) coats and jackets. All of these clothes are similar to the
spacesuit designs that keep astronauts comfortable in the temperatures of the
moon, and are spinoffs from space technology.
These
products are only a few examples of the many ways space technology helps us in
our everyday life. No one knows how new spinoff technology from the
International Space Station will help us in the future.
