The year 2018 was the busiest one for launches in decades. There were a total of 111 completely successful launches out of 114 attempts. It was the highest total since 1990, when 124 launches were conducted.
China set a new record for launches in 2018. The nation launched 39 times with 38 successes in a year that saw a private Chinese company fail in the country’s first ever orbital launch attempt.

The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)

In recent weeks, Chinese officials have revealed more details about the investigation into the Long March 5 launch failure last year as well as their ambitious launch plans for this year, which include a landing on the far side of the moon.
Long March 5 will be returned to flight in the second half of 2018, according to Bao Weimin, head of the Science and Technology Committee of the China Aerospace Science and Technology Corporation (CASC). Engineers have identified the cause of a launch failure that occurred last July and are working to verify it, he said.
With the successful maiden flight of its heavy-lift Long March 5 booster on Thursday, China has debuted four new launch vehicles in just under 14 months.
The list includes two new boosters — Long March 6 and Long March 11 — that are designed to serve the growing small-satellite launch market. The Long March 7 launcher is a medium-lift booster designed to replace several existing boosters.
China debuted the new medium-lift Long March 7 launch vehicle on Saturday from its new Wenchang Space Launch Center. It was the first launch from the new coastal spaceport.
The new booster carried a scaled-down version of a next-generation space vehicle designed to carry Chinese astronauts into Earth orbit and deep space. The spacecraft is set to land autonomously in Inner Mongolia after orbiting the Earth.
The two-stage Long March 7 is capable of launching 13,500 kg (29,800 lb) in low Earth orbit and 5,500 kg (12,100 lb) into sun synchronous orbit. The stages are powered by liquid oxygen and kerosene, which are cleaner than the hypergolic fuels that power older Long March boosters.
The new rocket is designed to replace the Long March 2 and Long March 3 boosters. The first stage is based on the Long March 2F rocket that is used to launch cosmonauts into space aboard Shenzhou spacecraft. The new booster shares engines with the Long March 5 and Long March 6 rockets.
