5 czerwca z kosmodromu Xichang wystartowała rakieta CZ-3A. Na orbitę geostacjonarną transferową (GTO) wyniesiony został satelita meteorologiczny Fengyun-2H.
Siedemnasty start orbitalny z Chin w 2018 roku rozpoczął się o godzinie 15:07 CEST. Lot zakończył się sukcesem i satelita został wprowadzony na orbitę GTO. Po czterech miesiącach samodzielnego lotu trafi na orbitę geostacjonarną nad 79 stopniem długości wschodniej. Satelita ma świadczyć usługi meteorologiczne dla Chińskiej Administracji Meteorologicznej przez co najmniej 4 lata. Obserwowane będą fragmenty Afryki, Bliski Wschód oraz Azja Centralna, regionów ważnych dla Chin z perspektywy ekspansji ekonomicznej w ramach programu “Jeden pas i jedna droga”.
Fengyun-2H należy do ostatniego z serii satelitów meteorologicznych rozwijanych od lat osiemdziesiątych a wynoszonych od 1997 roku. Satelity te są stabilizowane obrotem (100 rpm). Fengyun-2H waży 1380 kg. wyposażony jest w radiometr prowadzący obserwacje w świetle widzialnym i podczerwonym. Posiada również czujnik promieniowania X i cząstek wysokoenergetycznych do monitoringu tzw. pogody kosmicznej.
Co ciekawe po wyniesieniu satelity, górny stopień rakiety CZ-3A został zastosowany do przeprowadzenia eksperymentu zorganizowanego przez CALT, Chińską Akademię Technik Rakietowych. Na orbicie badano zachowanie ciekłego wodoru i tlenu w zbiornikach paliwowych. Wyniki mają zostać zastosowane do zaprojektowania nowych rakiet nośnych, w których paliwo kriogeniczne mogłoby zostać wykorzystane w parę godzin po starcie.

XICHANG, June 5 (Xinhua) -- China on Tuesday launched the new Fengyun-2H meteorological satellite to improve the accuracy of weather forecasting and provide better meteorological services to countries participating in the Belt and Road Initiative.
The Fengyun-2H was launched on a Long March-3A rocket at 9:07 p.m., Beijing Time, from the Xichang Satellite Launch Center in southwest China's Sichuan Province.
It was the 277th mission of the Long March rocket series.
A geostationary orbit satellite, the Fengyun-2H is the last in the Fengyun-2 series. The Fengyun-4 series will dominate China's new generation geostationary orbit meteorological satellites, said Zhao Jian, deputy director of the Department of System Engineering of China National Space Administration (CNSA).
In response to a request from the World Meteorological Organization (WMO) and the Asia-Pacific Space Cooperation Organization (APSCO), the position of Fengyun-2H will be changed from original 86.5 degrees east longitude to 79 degrees east longitude.
This means the Fengyun series satellites will be able to cover all the territory of China, as well as countries along the Belt and Road, the Indian Ocean and most African countries, according to the CNSA.
The adjustment will enable the Fengyun series satellites to acquire meteorological data over a wider range, improve weather forecasting accuracy and the ability to cope with climate change and mitigate losses caused by natural disasters, Zhao said.
Equipped with a scanning radiometer and space environment monitor, Fengyun-2H will provide real time cloud and water vapor images and space weather information to clients in the Asia-Pacific region, said Wei Caiying, chief commander of the ground application system of Fengyun-2H and deputy director of the National Satellite Meteorological Center.

(...) The SEM is a space weather instrument for charged particles at platform level. The instrument will count the number of electrons, protons and other charged particles hitting the platform.
The S-VISSR is an optomechanical system with scanning modes for normal scanning, optional scanning and single line scanning.
The telescope collects radiation during each scan and focuses it on the detectors in the focal plane using primary and secondary mirrors. The Si photodiode detector array has four elements mounted normal to the scan direction, providing 5 km wide instantaneous observation coverage on each scan line, matching the scan line width of the IR detectors with only one detector element.
The HgCdTe detectors are cooled by radiation coolers to a temperature of 100 K. A complete scan of 20º x 20º, covering the full Earth disk is obtained every 30 minutes by means of the spacecraft spin motion (100 rpm from E-W) and the step action (2500 steps from north to south) of the scan mirror.
The instrument will be used for determining the atmospheric temperature (column/profile), cloud liquid water (column/profile), cloud type, precipitation rate (liquid) at the surface, short-wave Earth surface bi-directional reflectance, sea surface temperature, ocean imagery, land surface temperature, vegetation type and land surface imagery.
The spacecraft during testing – Chinese State MediaFY-2H is also equipped with a solar X-ray detector for monitoring and early warning of solar flares (the Solar X-ray Monitor).
The development of the FY-2 geosynchronous meteorological satellite series began in the 1980s. (...)

(...) The China Meteorological Administration and other Chinese space authorities agreed to a request from the World Meteorological Organization and the Asia-Pacific Space Cooperation Organization to shift Fengyun 2H’s planned operating position westward from 86.5 degrees east to 79 degrees east, the Chinese weather agency said in a statement.
The location change will place Fengyun 2H over the Indian Ocean, giving the new satellite’s imager better coverage of Africa, the Middle East, and Central Asia, key focus regions for China’s “Belt and Road” foreign investment and infrastructure development initiative, intended to address the country’s long-term diplomatic, economic and military objectives.
