China's "Space ferry Bus" will be the first to take off this year

Xinhua, the National Committee of the CPPCC, Aerospace Technology Group, China Launch Vehicle Technology Research Institute Party secretary Liang 3rd, said in an interview with reporters, China's first space ferry vehicle will be flying this year, in the future exploration, such as deep space exploration mission, in orbit transfer, space debris clean-up and other orbital services in new materials The field of space test, such as new technology verification, will play an important role. Liang, China's launch Vehicle Technology Research Institute of the expedition to the top level, the first flight this year is imminent. The upper level is an autonomous independent vehicle that is launched into a quasi-Earth orbit or orbit by a base-level carrier, capable of further sending payloads from a quasi-Earth orbit or Earth orbit into a predetermined work orbit or a predetermined space position. From the late 80, our country has developed a multi-type solid propellant upper level, a total of 10 flights, all achieved a complete success. But the previous level was designed to meet a single task, the expedition of the upper level at the same time has a variety of characteristics, by the rocket designer called the real meaning of the space ferry vehicle. Liang Introduction, the development of the expedition of the first stage of the use of liquid propellant, on the track working time of 6.5 hours. The launch of the space ferry vehicle will greatly enhance the task adaptability of China's launcher. It is understood that the above level by the world's universal attention, up to now, the world's largest space research and development of the top level of more than dozens of species. "The four characteristics of space ferry vehicles" Both the carrier and the technical characteristics of the spacecraft, is in the launch vehicle or the re-use of the vehicle, the increase of relatively independent level or multi-level, can rely on their own power to carry the spacecraft to continue the flight. Can be started multiple times. After launching the launch vehicle into space, the shuttle vehicle can be ignited several times to meet the needs of different launch missions. Long working hours. Longer than the launch vehicle working hours, can reach several hours, days or even dozens of days. Different passengers can be sent to different destinations. In space, the space shuttle bus relay rockets continue to perform missions that can be transported directly to the work site through changes in the flight track that will carry one or more spacecraft.
