China's Long March 5 Rocket Returns To Flight

schwit1 shares a report from Space.com: China's biggest rocket, the Long March 5, returned to flight for the first time since a 2017 failure Friday (Dec. 27) in a dazzling nighttime launch for the Chinese space program. The Long March 5 Y3 rocket lifted off at 8:45 p.m. Beijing Time carrying the experimental Shijian 20 communications satellite into a geosynchronous orbit. The satellite, which weighs a reported 8 metric tons, is China's heaviest and most advanced satellite to date, according to state media reports. The successful launch is the first Long March 5 since a first-stage booster failure in 2017 destroyed the Shijian 18 satellite. The failure prompted redesigns in the rocket's first-stage engines, which led to a two-year gap between missions. The first Long March 5 rocket lifted off in 2016. The Long March 5 is an essential booster for China's space ambitions. The heavy-lift booster will be the one to launch China's space station modules into orbit, as well as a Mars lander in 2020 and the Chang'e 5 moon sample-return mission. China is also expected to use a version of the Long March 5, called the Long March 5B, to launch a new crewed spacecraft -- the successor to its current Shenzhou crew capsule.
