As the founder of a leading domestic commercial rocket enterprise, Zhang Changwu and his colleagues successfully launched the world's first liquid oxygen methane carrier rocket into orbit, achieving substantial progress for China's carrier rocket and aerospace industry. The reusability of rockets is a process that evolves from scratch and then from existence to excellence. Zhang Changwu described to everyone a phenomenon that few are aware of: the boundaries of natural language are the boundaries of systems engineering. Landspace Technology Corporation (Landspace), founded by Zhang Changwu, is a leading enterprise in China engaged in the creation and operation of aerospace transportation systems. Established in 2015, it is a national high-tech enterprise and a member of the International Astronautical Federation (IAF). Guided by national strategies and oriented by market demands, the company is committed to developing medium and large launch vehicle series using liquid oxygen methane as propellant, providing cost-effective and highly reliable launch services for the global market. Landspace is the first private launch vehicle enterprise in China to obtain all access qualifications. On October 27, 2018, it completed China's first private launch vehicle launch. In July 2023, its independently developed Zhuque-2 became the world's first liquid oxygen methane launch vehicle to successfully reach orbit. In the same year, it achieved consecutive launch successes and carried commercial satellites. To date, Landspace has achieved 4 consecutive launch successes, and continues to focus on liquid oxygen methane rocket and reusable rocket technologies, aiming to achieve high payload, high-frequency and low-cost rocket launches, contributing to China's satellite networking program.
