阅读理解Technology (技术)for space travel made our life on Earth better in many ways.Let's look at things we wouldn't have without space travel.
·Camera phones
In the 1990s NASA (美国国家航空航天局)made cameras small enough to fit on spacecraft.The technology is now used in cell phone cameras so that we can take selfies.
Sports shoes
There wouldn't be Nike Air trainers if we didn't go to space.The shock-absorbing(减震的) materials of the shoes come from space suits.
·Water cleaning system
In the 1960s,NASA created a technology to clean astronauts' drinking water.It is now widely used to clean water in swimming pools.
·Wireless (无线的)headset
Astronauts could easily get tangled up in wires,so NASA made wireless,hands-free headsets.
Astronauts can then move while talking and listening.
·Dust busters (手持吸尘器)
Astronauts hoped to collect samples on the moon.A company created a tool to help them do that.
The company then used this technology to make the dust buster in 1979.
·Computer mouse
In the past,you needed to type in codes(代码)in your computer to make it work for you.In 1968, a NASA researcher tried to make computers on spaceships easier to use,and this led to the creation of the mouse.
