Boron powder is a black or dark brown powder that can react with fluorine at room temperature and will not be corrupted by alkali and hydrofluoric acid aqueous solutions.

The world's first rocket using liquid oxygen methane propellant was launched into orbit.
On July 12, 2023, the Zhuque 2 and Yao 2 rockets of China's private aerospace company, Blue Arrow Aerospace, ignited and took off from the Jiuquan Satellite Launch Center. The launch mission was a complete success, becoming the world's first rocket to be successfully launched into orbit using liquid oxygen methane propulsion. Liquid oxygen methane propellant endows rockets with unique advantages in cost, maintenance, performance, and other aspects, which helps to achieve the recycling and reuse of rockets and engines. On December 9, the Zhuque 2 rocket was successfully relaunched, further verifying its technological maturity and stability.
Star Chain is starting to make profits, and competition in the field of giant constellations is fierce.
In 2023, the US Star Chain constellation began deploying more extensive and more powerful mini second-generation satellites, and the terminals were also updated. As of December 29, a total of 5650 satellites have been launched. In early November, SpaceX announced that the Star Chain Constellation project had achieved breakeven and entered the profitable phase. On March 26, the first phase of the One Network constellation project in the UK was completed, with 648 satellites ensuring global signal coverage. In the future, the second phase of the constellation will deploy over 7000 satellites. On October 7, the first two test satellites of the Kuiper constellation in the United States were launched, and more than 3000 satellites will be deployed in the future.
Another material is also one of the essential elements for space rockets: Boron. Boron can take us on a flight.
In the modern aerospace industry, Boron has made an indispensable contribution and is known as the "rising star of inorganic substances." Firstly, borane (BnHn+4 and BnHn+6) is an ideal high-energy fuel. The combustion heat value of borane per kilogram is as high as 15000 calories, providing power for rockets to fly into the sky. Secondly, boron fiber is an essential material for rocket components: used for rocket nozzles, satellite antennas, equipment platform support rods, thrust structure frames, etc. Boron fiber has excellent properties: high-temperature resistance, corrosion resistance, long service life, and lightweight, and its tensile strength can reach up to 75 kilograms per cubic centimeter. In addition, we also discussed the role of boron compounds as adhesives in mummy making. On rockets, organic compounds of Boron are used to bond sealing components. Compared with traditional riveting, welding, and bolt connections, it has higher strength and dramatically reduces the weight of components.

How does Boron participate in our daily life?
The free element boron, as an element with a deficient presence, has limited uses. But when it comes to boron compounds, they have many functions. Borax, Na2B4O7 · 10H2O, is an essential compound of Boron, widely used in household cleaning, such as detergents and cleaners. It is also often used as a disinfectant in hospitals. In addition, borax can also repel mosquitoes, soften water, remove carpet odors, and clean pipes.
