ry, greatly improving China's ability to launch spacecraft and laying the foundation for developing new-generation carrier rockets and heavy-lift launch vehicles, said Wang Xiaojun, head of the CALT. As a milestone project upgrading China's launch vehicles, the development of the Long March-5 covered the most d

iversified engineering technologies and overcame the most difficult problems in the country's carrier rocket history, completing a massive scale of tasks along the way. The Long March-5 rocket, with completely independent intellectual property rights, uses more than 200 key technologies. It is more complex than a

ny previous Long March rocket, and its design workload was more than 3.5 times that of previous projects. China also built the largest simulation laboratory in Asia for its tests. Advanced digital technologies were applied in the design, analysis and tests of the Long March-5 rocket, which greatly shortened the

development cycle and decreased costs. More than 10,000 space engineers participated in the design, research and development of the Long March-5, which lasted for more than 10 years. Friday's launch marks the end of a fruitful year for China's aerospace sector. Left part of the combo photo shows the lander of t
