Failure of one of the 2 YF-77 engines that power the 1st stage of the Long March 5 led to the loss of a mission in July 2017, seeing the launcher grounded for over 900 days. It made a successful return-to-flight in December.https://spacenews.com/successful-long-march-5-launch-opens-way-for-chinas-major-space-plans/ …
China's Mars mission, which is its first independent interplanetary mission, is seemingly on course for launch. Long March 5 launcher seems ready, parachutes tested, landing systems passed testing, ground stations & support ready.https://spectrum.ieee.org/tech-talk/aerospace/robotic-exploration/china-says-its-mars-landing-technology-is-ready-for-2020 …
