Oriented to the demands of national major strategies,economic and social development,CASC will continue to improve the integration of satellite applications into emerging areas,and support the economic development of key regions.The application of the BeiDou system will be extended to value added services from system integration with further efforts in the civil aviation industry,meanwhile expanding into other critical industries including energy and emergency.Making advantages with ground-space integration and comprehensive applications of satellite communications,navigation and remote sensing,CASC will focus on the opportunities of industrial and local governmental intelligence upgrades,building an integrated production system and supplying solutions for operational integrated applications.

CASC will carry out multiple commercial launch missions for the deployment of PIESAT-1,Jilin 1,GeeSAT and CentiSpace constellations,while publishing officially the information on available launch capacity,providing launch and piggyback opportunities for commercial customers as well as a quick,stable and reliable “one-stop” launching service to various kinds of customers to promote the healthy development of China’s commercial space sector.

DIFFICULTIES IN SPACE STATION TASK

MA Tao,an official from CASC announced that as the manned space station project enters the application and development phase,China’s Space Station has transferred to the normalized operation mode,China will complete launches of one cargo,two crewed and two return missions in 2023.

China’s T-shaped space station was completed on November 3,2022,and is orbiting normally in space as a complex with the Shenzhou 15 crewed spaceship and Tianzhou 5 cargo ship.The three-module space station will operate with the T-shape as the basic configuration for the long term,and extravehicular activities of astronauts and goods will be conducted aboard to support programs related to space science,materials and technical experiments.At the same time,maintenance and technical upgrade of the space station infrastructure will be arranged.Three “firsts” will be conducted in 2023,including the extravehicular payload support for a cascaded large and a small robotic arm,the payload installation by the smaller robotic arm and the extravehicular activities of astronauts and goods simultaneously.Tasks including in-orbit propellant refilling,electric propulsion testing and application and updates of several software systems will also be conducted in 2023.It is very difficult to implement this year’s in-orbit tasks for the space station and payload support,so it is a heavy task for ground support and development.

As for the crewed spaceship missions,the R&D for the spaceships remains at high intensity with several ships being developed in parallel.It has become normal to launch a spaceship every six months.According to the schedule,Shenzhou 16 and Shenzhou 17 crewed spaceships will be launched this year and a Tianzhou 6 cargo spacecraft will deliver supplies to the space station,including living necessities for astronauts on-board,test equipment and consumables for long-stays in space.

HEAVY LAUNCH VEHICLE PROJECT

China’s heavy launch vehicle development has always been a concern.An expert from the China Academy of Launch Vehicle Technology under CASC disclosed that the general concept of the seriation in configuration of the heavy launch vehicle has been clarified and the concept appraisals for systems such as TT&C at the launch site are under going.The conditions for project approval have been met and they will apply for project establishment.

The heavy launch vehicle can be used in many fields for a range of coverage,providing basic support for the implementation of large scale deep space explorations,such as building of a lunar scientific station,exploitation and utilization of lunar resources as well as construction of a research station on Mars and crewed Mars exploration.

China’s heavy rocket adopts three stages in serial as the basic configuration,with the launch capacity for the Earth-moon transfer orbit of 50 tons for deep space exploration missions.The 11-meter high carrier rocket has a 10-meter class rocket body diameter and has a lift-off weight of 4000 tons,giving a liftoff thrust of 6000 tons.The first stage is reusable.Based on the basic configuration,a two-stage serial configuration without the third stage is capable of carrying out near Earth orbit missions with a LEO launch capacity of 150 tons.In the future,the critical technologies for reuse of the second stage after orbital reentry will reach a breakthrough to develop a heavy launch vehicle with reusable ability.

The critical technology research and concept appraisals for the heavy launch vehicle were approved in June 2016.12 topics have been completed with critical technical breakthroughs,and are scheduled for final acceptance this year.Relying on the updated results achieved,the engineering development of the heavy launch vehicle might be finished 10 years after the project approval on the condition of all guarantees are in place in a timely manner.
