航空发展对未来的影响英语作文

Future development prospects of China's aviation industry

Manned space flight is the development of space technology to

a higher stage. However, due to the great difference between

manned space technology and unmanned space technology, which

is mainly reflected in three aspects: safety, complexity and high cost,

it has not shown a particularly obvious use since the first astronaut

went to heaven in 1961. However, in the foreseeable future, the

urgent problems facing mankind, such as resource depletion and

rapid population growth, can only be solved by opening up the

earth and expanding human living space. Even in contemporary

times, the development of manned spaceflight can also play the

following roles:

First of all, it can reflect a country's comprehensive national

strength and enhance its international prestige. Because the level

and achievements of aerospace technology are a comprehensive

reflection of a country's economic, scientific and technological

strength. Manned space flight is the development of space

technology to a higher stage, and the breakthrough of manned

space flight -- sending astronauts into space and safely returning

with domestic manned spacecraft is a symbol of a country's strong

comprehensive national strength. The development of manned

spaceflight depends on advanced technology, developed industrial

foundation and strong economic strength. So far, only Russia and

the United States have achieved manned space flight. Although

other countries with a certain aerospace technology foundation or

strong economic strength want to get involved in manned space,

they are unable to do so, so they can only resort to cooperation with

them, contribute money, and use Russian and American manned

spacecraft to send their astronauts into space, in order to gradually

join the world "manned space club". Comrade Deng Xiaoping once

said: without two bombs and one satellite, China will not have the

status of a great power. Therefore, the entry of Chinese astronauts

into space can also attract the attention of the world, improve

China's international status, inspire the national spirit and enhance

the cohesion of the whole people, just as China had "two bombs

and one satellite" in the 1960s and 1970s.

Secondly, it can reflect the achievements in many fields of

modern science and technology, and put forward new development

needs for various fields of modern science and technology, which

can greatly promote the development of the whole science and

technology, and will contribute to the training and cultivation of

Aerospace Science and technology talents. For example, in terms of

the development and operation of manned spacecraft itself, it puts

forward high requirements for technologies such as communication,

remote sensing, propulsion, measurement, materials, computers,

system engineering, automatic control, environmental control and

life support, which greatly promotes the progress of these

technologies.

Moreover, the development of manned spaceflight can

promote the development of space resources and benefit mankind

on earth. The high and remote position of manned spacecraft and

the special environment of microgravity can provide an ideal

experimental place for scientific research. It is playing an important

role in promoting life science and biotechnology, microgravity

science and application, and is expected to make breakthroughs in

some frontier disciplines and bring great benefits to mankind. Some

countries have made remarkable achievements in the fields of space

pharmaceutical, space breeding and space material processing, and

are preparing to build space factories, with unlimited efficiency and

benefits.

Finally, manned space flight has great military potential. Using

manned spacecraft can accomplish reconnaissance and surveillance

tasks well; Flexibly deploy, repair and assemble large military

satellites; Safely and continuously command and control ground

military forces; It can also be used as a testing ground for special

weapons. For example, as early as December 1965, the astronauts

on the US Gemini 7 spacecraft used infrared remote sensors to

monitor and track the launch of a submarine launched missile, and

the information obtained was faster than that reported by the

observers on the submarine. During the first and second Gulf wars,

astronauts on Mir space station and international space station

carried out a lot of observation activities in the theater and obtained

a lot of useful information.

It is understood that China's manned spaceflight will implement

the "three-step" development strategy. On the basis of successfully

launching an unmanned test spacecraft, China has sent astronauts

into space, achieving a historic breakthrough in manned space flight.

However, this is only the first step. In the second step, in addition to

continuing to carry out earth observation and space tests with

manned spacecraft, the focus will be on extravehicular activities,

space rendezvous and docking tests, and the launch of long-term

autonomous flight and short-term manned space laboratories, so as

to build a complete supporting large-scale space engineering

system as soon as possible and solve the problem of space

applications on a certain scale. The third step is to build a larger

space station with long-term care. So as to strengthen the research

of Pacific Space and narrow the gap with the United States and

Russia. Realize your dream of becoming a powerful country.
