Lesson 4 Technology and Our Lives
Space Technology for Everyday Use
Did you ____ that many technologies around us originated from space technology?
You may not ____ realized it, but we have been enjoying the enormous benefits of space technology in our daily lives for a long time.
Let’s see how some examples of it have been invented and integrated ____ our daily lives already.
Memory foam
Memory foam was initially ____ to minimize the effects of the force of gravity on astronauts during takeoff and landing.
Memory foam absorbs shock by changing its shape in ____ to pressure, and it can change its shape to match the body shape of an astronaut.
Once the pressure is lifted, memory foam gradually returns to ____ original shape, as if it remembered its original form.
Because ____ this characteristic, it is called “memory” foam.
It provides astronauts with improved protection and comfort when they are ____ their seats.
Since memory foam was first introduced into the public domain, it has been used in ____ number of products such as beds and sofas.
Water purifier
Today’s ____ purifier also originated from space technology.
While planning their human space exploration program, NASA scientists realized ____ it was impossible to load a sufficient amount of clean water into a spacecraft.
Then, they hit upon an idea that wastewater could be ____ once harmful bacteria were removed.
So they developed a ____ purification system that could successfully kill off bacteria.
Continued research led to the invention of a better water purification system that uses cartridges for longer missions ____ did not need to be replaced frequently.
This water purifying technique was developed for several decades and ____ marketed for domestic use.
Air purifier
Another everyday item developed from space technology is the ____ purifier.
A reliable source of food was vital for ____ in space.
In order to get fresh food, astronauts ____ to cultivate crops in the spacecraft.
____ there was a major obstacle.
____ plants grow, ethylene gas is produced.
It accelerates the aging of plants and the ____ of fruits.
____ it was impossible to exchange gas for clean air while in space, scientists developed an air purification system to remove the gas.
Although the goal was to eliminate ethylene, ____ system could get rid of other unwanted things from the air, too.
A private company recognized the potential of the air purification system and obtained a license ____ develop and commercialize it.
Wireless headset
The fourth invention is the wireless ____
It was devised after ____ unexpected incident NASA had experienced.
The second manned spacecraft launched by ____ U.S. completed its mission and successfully landed in the Atlantic Ocean.
The command pilot was waiting for the recovery ____ that would get him and the capsule from the ocean.
Everything was going smoothly until ____ the capsule started to leak.
Water flooded into the cabin before the team arrived, and ____ pilot had to escape, abandoning all of the spacecraft’s radio communications equipment.
This ____ him from communicating with the recovery team.
He was left floating in ____ ocean until he succeeded in visibly getting the rescue helicopter’s attention.
After this accident, NASA and a partner company developed helmets equipped with a ____ system that could communicate with a designated base station.
Later, wireless headsets using ____ system were introduced to the world.
These ____ Bluetooth technology has been incorporated into wireless headsets.
Now ____ can connect headsets wirelessly with mobile digital devices such as smartphones and laptops.
In our daily lives, there are ____ other inventions that have their origins in space technology including the smartphone camera and the computer mouse.
____ firms as well as government organizations have invested heavily in space technology for space exploration.
Therefore, we can expect ____ our future lives will be significantly influenced by space technology that has not yet been invented.
