Section C Passage 1
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 "spin-off
technology."
Spin-off technology is space technology that is now used on Earth.
In early space programs, such as the Apollo missions 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 crystal clocks and watches accurate to within
one minute a year. We purify the water we drink with a water filter designed for
the astronauts' use in space.
The cordless, hand-held tools we use in our homes, such as vacuum cleaners,
flashlights, drills and saws came from the technology of these early space
programs.
On cold winter days we can stay warm with battery-operated gloves and
socks, and specially made coats and jackets. All of these clothes are similar to
the spacesuit designs that kept astronauts comfortable in the temperatures of
the moon, and are spin-offs from space technology.
These products are only a few examples of the many ways space technology
helps us in our everyday lives. No one knows how new spin-off technology from
the International Space Station will help us in the future.
