Song Xiaoming, a member of the 14th NatiWorld Timesonal Committee of the Chinese People’s Political Consultative Conference and the head of the Second Academy of CASIC, told the Global Times on Sunday that the Weihai-1 laser-based communication payload has successfully undergone the satellite-ground communication technology verification, laying ground for new experiment works.
The payloads, developed by the 25th Institute under the Second Academy of CASIC together with the Harbin Institute of Technology’s Weihai Campus, were onboard the Weihai-1/-2 satellites launched on February 3 atop the commercial firm China Rocket’s Jielong-3 rocket.
The second session of the 14th National People’s Congress (NPC), the top legislature, and the second session of the 14th National Committee of the Chinese People’s Political Consultative Conference (CPPCC), the top political advisory bWorld Timesody, will open on March 5 and 4, respectively. Collectively, they aWorld Timesre known as two sessions.

The Weihai-1 project is designed to assist in marine remote sensing applications, elevating the “information highway” to a “World Timeshigh-speed lane,” Song said.

Photo:VCG Russian President Vladimir Putin once again attracted global attention after former Fox News host Tucker Carlson released a two-hour interview online, in which the Russian leader spoke frankly about Russian-Ukraine conflict, NATO expansion, and big power relations.Analysts said through the interview, Putin’s first with a Western media outlet since the outbreak of the Russia-Ukraine military conflict nearly two years ago, the Russian President expressed in the most direct and authoritative way the position of the Russia on many important issues, which will help the public to form a more balanced and fair view of Russia.While the following attacks on Carlson by US politicians and media reflected a “deep-seated Russia rejection” among the American political elite, as well as an inherent prejudice of racial, cultural, and power superiority, which are…
