The burning of aircraft and rocket fuels produces significant amounts of carbon dioxide. Carbon dioxide is among the greenhouse gases at the root of global warming. In spite of international agreements to cut emissions, including the Paris Agreement, carbon emissions from aviation fuel continue to rise each year. To reduce this part of the carbon emissions, on the one hand, we need to develop more environmentally friendly fuels. On the other hand, we also need to optimize engine design and improve fuel combustion efficiency.

Nitrogen oxides from aircraft and rocket combustion also have a serious impact on the atmosphere. These nitrogen oxides react with atmospheric water and oxygen to form nitric acid and nitrates, which are the main components of acid rain. At the same time, these nitrates are also key substances in the formation of photochemical smog in the atmosphere, which seriously affects air quality.

In addition, the noise pollution generated by rocket launches and aircraft takeoff and landing can not be ignored. The rocket launch will produce a huge noise at the moment, which will have a serious impact on the living and working environment of the surrounding residents. The noise of airplane landing and takeoff will disrupt the quality of life and rest of residents, leading to a decrease in sleep quality and the risk of developing cardiovascular diseases over the long term.

While the advancement of research into aviation-related fuels is progressing in a more eco-sustainable and efficient direction, including bio-fuels and hydrogen fuels, however, the research and development of these fuels are costly, and their promotion and implementation of these fuels are still facing numerous obstacles.

The consumption of conventional materials such as steel is also a problem that cannot be ignored. Aerospace spacecraft require a lot of high-quality steel and other metal materials to manufacture. The mining and processing of these materials consumes a lot of energy and also produces a lot of waste and pollutants. In addition, the production and use of these materials have a relatively large impact on the environment, and more environmentally friendly production methods and use methods need to be adopted.

The use of rare earth elemental elements is an issue. Rare earth elements are indispensable and key materials in aerospace technology, such as the manufacture of advanced turbine engines that require large quantities of rare earth elements. However, the reserves of rare earth elements are limited, and excessive exploitation will lead to resource depletion. Moreover, the exploitation and use of rare earth elements will also have a serious impact on the environment, such as destroying vegetation and polluting water sources.

● Economic Challenge

The development of the aerospace industry does require a large amount of economic investment. This field covers everything from the manufacture of aircraft the launch of rockets, to the implementation of space missions, and each step requires huge financial support. Aircraft manufacturing is a typical example. It requires a large amount of capital investment, including research and development, prototype manufacturing, test verification, production line construction, and other aspects. These require strong financial strength and long-term investment commitments.

At the same time, the commercialization of the aerospace sector also needs to be supported by the market to achieve sustainable growth. As technology advances and market competition intensifies, the aerospace sector needs to constantly innovate and improve to maintain its leadership and profitability. This requires the aerospace sector to be able to effectively communicate and cooperate with the market, understand market needs and changes, and also need policy support to promote market competition and industry development.

Policy support can take many forms, such as providing research and development funding, tax incentives, market access, etc. These policies can help the aerospace sector attract more investment, expand the scale of the industry, and improve market competitiveness, thus promoting sustainable development in the sector.
