China launched a long March 2C recall during a Haiyang-1C maritime satellite delivery mission in space. The rocket took off at 23:15 EDT 6 September (11:15 local time / 03:15 GMT 7 September), 2018, from the Taiyuan Satellite Launch Center in China's Shanxi Province.
The launch was not announced with only a notice to airmen (NOTAM) issued Sept. 6 stating an imminent orbital mission. The confirmation of the successful launch took place three hours after takeoff by the official Xinhua News Agency.
"China has sent a new maritime satellite into orbit Friday to help better understand maritime waters and climate change" Xinhua reported.
Chinese officials have not revealed any details about orbital flight. However, since the satellite was delivered in a Sun-synchronous orbit (SSO) at an altitude of approximately 485 miles (780 kilometers), the mission probably lasted approximately 20-30 minutes between takeoff and payload deployment. .
Haiyang-1C was developed by China Spacesat Co., Ltd., a subsidiary of the Chinese Academy of Space Technology (THROW). It weighs approximately 444 kilograms and is based on the CAST968 platform, which includes two deployable solar batteries and batteries that can generate up to 510 watts of power. Its dimensions are: 4.6 x 3.6 x 3.13 feet (1.4 x 1.1 x 0.953 meters).
According to the China National Science, Technology and Industry Administration, Haiyang-1C is expected to operate for five years to monitor ocean color and water temperature, providing basic data for the research on the global ocean environment. It will also be used to study the resources and the environment of China's offshore waters, islands and coastal areas, as well as to assist with disaster relief and the sustainable use of ocean resources.
To carry out its scheduled tasks, Haiyang-1C is equipped with a medium-resolution optical imager called China Ocean Color and Temperature Scanner, as well as a multi-spectral push-pull CCD instrument called Coastal Zone. Imager.
Wang Lili, chief designer of Haiyang-1C, m said the spacecraft will be able to detect concentrations of chlorophyll and suspended sediment and dissolved organic matter, which can affect the color of the ocean as well as the sea surface temperatures. These data could help to study the resources and environments of fishing and aquaculture.
Haiyang-1C is the third satellite in the series. Haiyang-1A was launched in May 2002 with Haiyang-1B about five years later, in April 2007. Xinhua reported Haiyang-1C, with Haiyang-1D (scheduled for launch in 2019), is expected to improve China's oceanic remote sensing capability.
The Long March 2C propeller used for Friday's flight is a two-stage rocket developed by the China Academy of Launch Vehicle Technology. It is mainly used to send satellites in Low Earth Orbit (LEO) and SSO. The 42-foot (138-foot) launcher is capable of lifting payloads up to 3.85 metric tons to LEO and has a SSO capacity of up to 1.4 tons. For some missions, an optional third step may be included.
Friday's mission marked the 284th general launch of the Long March rocket series and the 24th China-led orbital flight in 2018. The country is currently targeted on 20 September 2018 for its next mission, which should see a Kuaizhou 1A rocket. deliver the Centispace-1 1S in an SSO.
