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