It was the former Soviet Union that successfully orbited the earth.
Everyone won the space race. So far, the whole country of the United States has been affected.

Sending a man to the moon for the first time,
The United States finally got a stage in the "space race"
Sexual victory.
Since then,
Although the former Soviet Union gave up its manned moon landing competition with the United States, it was ahead of the United States in space station technology.
Embarked on its own unique road to space. near

Although the "space race" in 2000 had a strong political and military background, it was a guest.
It has greatly promoted the scientific and technological progress of mankind, similar to the invention of nuclear weapons.
And transformed into nuclear power technology, the resulting high-tech and products are rapid.
The conversion to civilian use has benefited us a lot.
From space food to instant noodles and vegetables
Open the vegetable bag of instant noodles, there are some dried vegetable leaves scattered inside.
Onions and carrots. These dried vegetable leaves are what we often call dehydrated vegetables, which remove excess water from vegetables, while fresh vegetables
Chlorophyll and vitamins contained in it can still be retained, which is convenient for storage, preservation, transportation and sales. People in the Apollo program
For the first time, scientists used this technology to let astronauts eat space food containing vegetables. Now you can also enjoy this dehydrated vegetable.
Yes, although I don't like instant noodles very much.
artificial heart
Space technology is always first applied to the research of civil frontier science, especially in the field of life-saving medicine. All kinds at present
Transplantation is very common, and the technology of liver and kidney transplantation is improving day by day. However, if you can't find a suitable heart source, wait for the patient's wishes.
This is death.

A Jewish hospital in Louisville, Kentucky, USA successfully replaced a patient with terminal heart disease.
Artificial heart, this is the first successful artificial heart transplant in the world. The technology of artificial heart comes from the space shuttle.
With the development of fuel pump technology, this miniature heart pump has brought new life to dozens of people.
Car navigation
If you drive in a strange city,
You must want someone to show you the way,
However, pedestrians are often the result.
I don't know. Then what should I do? Now, the combination of satellite signals and map data is displayed on a small screen.
The device can determine the position of the car at any time and help the driver to confirm the road accurately. Install the receiver on the car.
Global (satellite) positioning system
(Global Positioning System)
System) equipment, as long as you find the place you want to go on the electronic map, the electronic map combined with satellite signals can be calculated.
Tell you the shortest route.
If the car has the function of self-driving, it can be borrowed like the current civil aviation plane.

Go anywhere you want.
Purification of water and air
In the Apollo moon landing program,
The moon landing spacecraft will take a long time to fly.
The water and air carried are very limited,
this
All the necessities of life need to be recycled to meet the demand.
Water purification technology has given today's urban sewage treatment technology and seawater desalination.
Technology has a great influence. Air purification technology is very different from the technology of making oxygen in submarines, which emphasizes recycling and energy saving.
Keep it longer. These technologies are of great practical significance to our increasingly polluted earth.
Space technology and happy life
China's Shenzhou VI manned spacecraft will be launched soon. be like

One of the greatest technological advances of this century, space technology.
Art has written a series of legends on the road of human exploration of the universe. Every major breakthrough in space technology will lead to
Profound changes in productive forces and great progress in human society. Space-is quietly moving from a field that can only be imagined in the past.
Into people's real lives.
Explore the mysteries of the universe
Find out the family background of the earth
People not only use space technology to look up at space, but also bend down to observe us.

Monitoring and other services provide farmers with crop yield estimation and pest prediction, and also provide fishermen with fish location information.
