![]() The launch was planned to take place at around 10:00 UTC on 3 November 2016, but several issues, involving an oxygen vent and chilling of the engines, were detected during the preparation, causing a delay of nearly three hours. The final production and testing of the first CZ-5 rocket to be launched into orbit were completed at its Tianjin manufacturing facility on or about 16 August 2016 and the various segments of the rocket were shipped to the launch center on Hainan island shortly thereafter. The maiden flight of the CZ-5 was initially scheduled for 2014, but this subsequently slipped to 2016. The first production CZ-5 was shipped from the port of Tianjin in North China to Wenchang Space Launch Site on Hainan Island on 20 September 2015 for launch rehearsals. The first photos of a CZ-5, undergoing tests, were released in March 2015. In July 2012, a new 1200 kN thrust LOX/ kerosene engine to be used on the Long March 5 boosters was test-fired by China. At the time, the new rocket was expected to be manufactured at a facility in Tianjin, a coastal city near Beijing, while launch was expected to occur at the new Wenchang Space Launch Site in the southernmost island province of Hainan. ![]() Formal approval of the Long March 5 program occurred in 2007 following two decades of feasibility studies when funding was finally granted by the Chinese government. Ĭhina's main objective for initiating the new CZ-5 program in 2007 was in anticipation of its future requirement for larger LEO and GTO payload capacities during the next 20–30 years period. Additionally, China had been able to secure some international launch contracts by offering package deals that bundle launch vehicles with Chinese satellites, thereby circumventing the effects of U.S. Growing domestic demand for launch services has also allowed China's state launch provider to maintain a healthy manifest. Since 2010, Long March launches (all versions) have made up 15–25% of the global launch totals. History Rendering of Long March 5 and 5B Proposal and development Īfter an interval of almost two and a half years, the Long March 5 vehicle's return to flight mission (third launch) successfully occurred on 27 December 2019 with the launch and placement of the experimental Shijian-20 communications satellite into geostationary transfer orbit, thereby paving the way for the successful launch of Tianwen 1 Mars mission, lunar Chang'e 5 sample-return mission, and the modular space station, all of which require the lifting capabilities of a heavy lift launch vehicle. The second CZ-5 rocket, launched on 2 July 2017, failed due to an engine problem in the first stage. The first CZ-5 launched from Wenchang Space Launch Site on 3 November 2016 and placed its payload in a suboptimal but workable initial orbit. It is currently the most powerful member of the Long March rocket family and the world's fourth most powerful orbital launch vehicle currently in operation, trailing the Delta IV Heavy, Falcon Heavy, and the Space Launch System. The Long March 5 roughly matches the capabilities of American NSSL heavy-lift launch vehicles such as the Delta IV Heavy. ![]() The maximum payload capacities are approximately 25,000 kg (55,000 lb) to low Earth orbit (for CZ-5B) and approximately 14,000 kg (31,000 lb) to geostationary transfer orbit (for CZ-5). There are currently two CZ-5 variants: CZ-5 and CZ-5B. ![]() It is the fifth iteration of the Long March rocket family. It is the first Chinese launch vehicle designed to use exclusively non- hypergolic liquid propellants. Long March 5 ( LM-5 Chinese: 长征五号 pinyin: Chángzhēng wǔ hào), or Changzheng 5 ( CZ-5), and also by its nickname " Pang-Wu" (胖五, " Fat-Five"), is a Chinese heavy-lift launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT).
