China is one step closer to Mars.
China launched yesterday (Friday 27 Dec 2019) a Long March-5 rocket, one of the most powerful launchers in the world, a crucial stage in the Chinese space program, notably for a mission to Mars scheduled for 2020. This Lomgue March rocket -5 left the site of Wenchang, in the tropical island of Hainan, at 8:45 pm local time, according to images broadcast live by the state television CCTV. The Chinese launcher, equivalent to the European Ariane-5 rocket, the American Delta IV Heavy, or the Russian Proton M., is one of the fundamental links of the Chinese space program, planning a mission to the red planet in 2020 and a space station by 2022.

WENCHANG, Hainan, December 28 (Xinhua) - China launched the third Long March-5, the country's largest carrier rocket, from the Wenchang Space Launch Center in south China's Hainan province on Friday evening .
The rocket, Long March-5 Y3, took off from the launch center at 8:45 p.m. Beijing time, carrying the Shijian-20 technology experiment satellite. This more than eight-ton satellite is the heaviest and most advanced communications satellite in the country.
About 2,220 seconds later, the satellite entered its planned orbit.
Wu Yanhua, deputy director of China's National Space Administration, said the launch was a success.
The successful launch lays the groundwork for a future series of space projects for the country, including exploring Mars, returning lunar samples, and building a space station, said Wu.
The Shijian-20 satellite will be used to test important technologies for DFH-5, a large next-generation platform for large satellites, and to provide communication and broadcast services, said Wu.
The Long March-5 is a two-stage rocket capable of carrying a payload of 25 tonnes, equivalent to the weight of 16 cars, in low Earth orbit, 14 tonnes in geostationary transfer orbit, eight tonnes in orbit Earth-Moon transfer, or five tonnes in Earth-Mars transfer orbit. Its capacity is more than twice that of the main Longue Marche family rockets currently in service. With an upper stage, the rocket is capable of sending probes to explore Jupiter and other planets in the solar system, according to the China Aerospace Science and Technology Corporation (CASC).
The Long March-5 launched its inaugural on November 3, 2016 from Wenchang. However, the second large rocket, Longue Marche-5 Y2, failed on July 2, 2017, due to a malfunction that occurred less than six minutes after takeoff.
The research team identified the cause of the failure, a problem with the rocket's first stage engine. "We have made improvements in engine concept, materials and technology," said Li Dong, chief designer of the Long March-5 rocket at the Chinese Academy of Launch Vehicle Technology in China, noting at the CASC.
The rocket is approximately 57 meters high, the equivalent of a 20-story building, with a central stage of five meters in diameter and four thrusters of 3.35 meters in diameter. The Long March-5 is much larger than China's previous carrier rockets. It has a takeoff weight of around 870 tonnes and a thrust of over 1,000 tonnes.
The four thrusters, developed by the Shanghai Academy of Space Flight Technologies, which is dependent on the CASC, support more than 90% of the take-off weight.
The rocket uses environmentally friendly fuels, including kerosene, liquid hydrogen and liquid oxygen.
