According to the "Our Space" public account, at 12:00 today, my country used the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center to successfully launch the satellite Internet technology test satellite. The satellite successfully entered the predetermined orbit, and the launch mission was a complete success.

The satellite is mainly used to conduct technical tests and verifications such as mobile broadband direct connection to satellites and space-to-ground network integration.

The Changerding rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is a normal-temperature liquid two-stage launch vehicle with single- and multi-satellite launch capabilities for different orbital requirements. Its sun-synchronous orbit carrying capacity is 1.3 tons.

It is understood that this launch mission successfully used a 3.8-meter-diameter composite satellite fairing. This type of fairing uses lightweight design and advanced material technology.Three major breakthroughs have been achieved compared with metal fairings of the same size:

Effectively expand the satellite payload envelope space and significantly improve mission adaptability;

The electromagnetic wave penetration performance is greatly improved to ensure the reliability of wireless communication links;

The inner surface is smooth and easy to clean, meeting the requirements of high-cleanliness aerospace environments.
