In-orbit test of China's first orbiting carbon observatory satellite has been successfully completed, according to China Meteorological Administration. The satellite transmits signals to the National Satellite Meteorological Center (NSMC) every 1.5 hours from its preset orbit 700 kilometers above Earth. The satellite, TanSat, was launched on December 22, 2016, and has been in space for more than eight months. As China's first mission to study carbon dioxide, the satellite examines carbon sources with extremely high precision, tracks the role of carbon dioxide in the carbon cycle, studies variability over time, and helps forecast long-term climate change caused by carbon dioxide emissions. Different from traditional meteorological satellites, TanSat detects the concentration of carbon dioxide by molecule absorption in the visible and near infrared, said NSMC Deputy Director Zhang Peng. Equipped with a modularized satellite platform, a hyperspectral carbon monoxide detector, and a multispectral cloud and aerosol detector, the satellite offers very accurate measurements. It has five modes of observation and is capable of examining from different angles. The results of the in-orbit test proved that every function of the craft is in good operation and each index of the satellite platform has met requirements, Zhang noted. Scientists will convert the magnetic signals received from the satellite into visible spectral signals, and then calculate the concentration of the carbon dioxide, Zhang said, adding that the data will be available for all researchers. fabric wristbandsjordan wristband rubberrubber bracelet makertrio spinnerswristband creationcustom sweatbands no minimumuv bracelet
PYONGYANG - The Democratic People's Republic of Korea (DPRK) said Saturday that the latest US-ROK (Republic of Korea) joint military drills were "unprecedentedly hideous and most adventurous ones" in several decades. In a military commentary, the official Korean Central News Agency said the US and ROK have made it public that all their joint military drills aimed to "remove the leadership" of the DPRK and "bring down its system." These exercises had "thrown away their deceptive veils as annual drills and defensive ones," it said. "The Key Resolve and Foal Eagle 17 joint military drills revealed that the new Trump administration, too, is resorting to the hostile policy toward the DPRK by use of force, tougher sanctions and pressure," it said. The US and ROK have just concluded two-month-long joint military drills involving 300,000 troops. The US has also sent its aircraft carrier task group USS Carl Vinson and a nuclear submarine to waters off the Korean peninsula, besides carrying out nuclear bomb dropping drills in ROK and test launching two intercontinental ballistic missile within one week from California to the Western Pacific over the past two weeks.
