Long March 5 are heavy rockets developed by China to be a cornerstone of its space ambitions. It can carry weights of up to 55,000lbs into low Earth orbit, and 31,000 into geostationary orbit. The two stage rocket is similar in capability to the US Delta IV Heavy - and is regarded as the third most powerful rocket in the world after the Delta and SpaceX's Flacon Heavy. It is 187ft high, 16ft in diameter and weighs an incredible 1,883,900lbs. Seven of the rockets have been launched - with one failure back in July 2017. China has another seven launches planned - including two more delivering parts to an under construction space station in 2022.
