China's Long March-4B Successfully Launches Haiyang-2E Satellite

en.Wedoany.com Reported - At 07:46 on July 2, the Long March-4B carrier rocket ignited and lifted off from the Jiuquan Satellite Launch Center, subsequently sending the Haiyang-2E satellite into its predetermined orbit, marking a complete success for the launch mission.

The Haiyang-2E satellite, developed under the leadership of the Fifth Academy of China Aerospace Science and Technology Corporation (CASC), is primarily used for marine rights protection, disaster prevention and mitigation, marine resource development, and marine scientific research. This satellite will replace the Haiyang-2B satellite launched in 2018 and will form a network with the in-orbit Haiyang-2C and Haiyang-2D satellites, ushering in a new chapter for the second phase of China's marine dynamic environment satellite constellation, ensuring the continuous and stable operation of China's marine dynamic environment monitoring services.

The satellite continues the efficient comprehensive detection approach of the Haiyang-2 series satellites, with technological upgrades to its payloads, significantly enhancing its observation capabilities in coastal waters.

The Long March-4B rocket used for this launch mission is a room-temperature liquid three-stage carrier rocket developed under the leadership of the Eighth Academy of CASC. It is capable of launching various types of satellites with different orbital requirements and can perform single-satellite or multi-satellite launch missions, with a payload capacity of up to 2.5 tons to a 700-kilometer sun-synchronous orbit.

In this mission, the Long March-4B rocket adopted a parallel refueling mode for the first time under high-temperature conditions. During the mission, the launch site experienced hot and dry weather accompanied by strong winds and sandstorms. The rocket test team fully leveraged mature experience from previous summer launches, collaborating with the launch site system to conduct multiple rounds of calculations and tests, continuously refining prevention and control strategies to ensure the rocket's launch capability under extreme high-temperature conditions.

This launch marks the 654th flight of the Long March series carrier rockets.
