China recently used the 251st launch of a Long March 2C carrier rocket to put three Yaogan 30-1 electro-magnetic sensory satellites developed by the Chinese Academy of Sciences into orbit, a resumption of space launches after a major failure in July, said China Aerospace Science and Technology Corp, the major contractor of the country's space programs.

This launch confirms that efforts to improve its rockets' quality have borne fruit, a result sure to bring confidence to its workers, the company noted.

The July failure meant the country had to postpone several key missions, including the Chang'e 5 lunar expedition.

The Long March 5 has a liftoff weight of 869 metric tons, a maximum payload of 25 tons to low-Earth orbit and a max payload of 14 tons to a geosynchronous transfer orbit. Its payload capacity is about 2.5 times bigger than any other Chinese rocket.

The rocket's first flight was carried out in November, 2016. Scientists wish to use the rocket to send large probes to the moon, Mars and Jupiter. They also plan to use it to transport parts for a manned space station beginning around 2019.
