The idea is not new — in the 70-ies of the last century this technology has been considered by the USA and the USSR, but due to various technical problems and has not received wide distribution. That such research and development are in China, did Tongyu, head of the missile unit of the Chinese Academy of rocketry.
As a launch pad you intend to use strategic aircraft Y-20 or similar for the transport, manufacturing and the supply of which began last summer. The capacity of this aircraft is 66 tons, so in theory to take on Board as cargo solid fuel booster, he is quite capable. If the project goes ahead, it will help when you start to do without a spaceport and significantly reduce the time required to prepare the launch.

the History of evolution has repeatedly witnessed the eternal debate about what was first – the egg or the chicken — however one of the most interesting mysteries is: was there life before the advent of nucleic acids? In the new study, scientists have provided evidence that primitive biochemistry was able to appear and grow without phosphates – one of the most important and key structural components of nucleic acids that are included in our genetic chemistry — which adds weight to the assumptions, according to which before the appearance of life could be metabolism.
