China launched a high-power communications satellite Saturday on a mission to connect airline passengers, maritime vessels, and other users across China, Southeast Asia, and remote routes between the Asia-Pacific region and North America.<\/p>\n

The Chinasat 19, or Zhongxing 19, communications satellite lifted off on a Long March 3B rocket at 7:50 a.m. EDT (1150 GMT) Saturday from the Xichang launch base in Sichuan province of southwestern China.<\/p>\n

The Long March 3B took off powered by a core stage and booster engines fueled by toxic hydrazine. The rocket shed its strap-on boosters and core stage in the first three minutes of the flight, then a second stage took over to continue accelerating into space. A cryogenic third stage fueled by liquid hydrogen finished the job of placing the Chinasat 19 satellite into an elliptical, or oval-shaped, transfer orbit ranging between 136 miles (220 kilometers) nearly 22,250 miles (35,800 kilometers) in altitude.<\/p>\n

U.S. military tracking data confirmed the mission placed the Chinasat 19 satellite into the intended orbit, and Chinese officials declared the launch a success. Chinasat 19 will use its own propulsion to reach a circular geosynchronous orbit more than 22,000 miles over the equator, where it will take position over the Asia-Pacific region and orbit in lock-step with Earth\u2019s rotation.<\/p>\n

The Chinasat 19 satellite was built by the China Academy of Space Technology, or CAST, a state-owned aerospace contractor. Chinasat 19 is based on the enhanced DFH-4E satellite bus, a derivative of the DFH-4 platform used by dozens of Chinese satellites since 2006.<\/p>\n

Designed for a 15-year lifetime, Chinasat 19 is owned by China Satcom, which provides civilian communications services across the country. Chinasat 19 carries a Ka-band high-throughout communications payload designed for broadband internet services, and also hosts Ku-band and C-band transponders.<\/p>\n

Chinasat 19 will help replace coverage that was planned to be provided by Chinasat 18, a similar satellite that failed shortly after launch in 2019. The new satellite will offer a \u201cfast transmission rate and wide coverage,\u201d according to the China Aerospace Science and Technology Corp., or CASC, the top state-owned contractor in China\u2019s space program.<\/p>\n

Once operational, Chinasat 19 will connect users in eastern China, Southeast Asia, and most of the Pacific region including routes between Asia and North America for ships and airplanes.<\/p>\n
