THE Yuanwang-6 space-tracking ship returned to its homeport Monday after completing its telemetry, tracking and command (TT&C) tasks for the Tianzhou-2 cargo spacecraft and Shenzhou-12 manned spaceship missions. Yuanwang-6, China’s third-generation space-tracking ship, was at sea for 29 days, sailing more than 5,000 nautical miles for the two missions. On May 29, China launched Tianzhou-2. The cargo freighter, carrying supplies, equipment and propellant, successfully docked with the space station core module Tianhe on May 30. On June 17, China successfully launched Shenzhou-12, with three astronauts on board for space station construction. Yuanwang-6 has provided vital communication between the spacecraft and the ground. When the Shenzhou-12 spaceship, atop a Long March-2F carrier rocket, reached the TT&C range of Yuangwang-6 sailing in the Pacific Ocean at the time, the space-tracking ship discovered and captured the signals of the spaceship promptly. The tracking vessel helped Shenzhou-12 undertake several key moves, including orbit entry and unfolding of solar panels, providing significant data support for the missions. (CGTN) |
