1. China’s Manned Space Engineering Program

In September 1992, Chinese government made a decision to implement the manned

space engineering project and prescribed a “Three-step Strategy” of development

1. China’s Manned Space Engineering Program

• The first step is to launch a manned spaceship, set up primarily integrated

experimental manned spacecraft engineering, and carry out space

experiments.

• The second step is to make technology breakthroughs in Extravehicular

Activities as well as space rendezvous and docking of the program, launch

the space lab, and provide a solution for space utilization of a certain scale

with man-tending on a short-term basis.

• The third step is to establish a space station, and provide a solution for

space utilization of larger scale with man-tending on a long-term basis.

Tiangong2 ,3 (or Spacelab) and several Shenzhou spaceships are planned before 2016.

1. China’s Manned Space Engineering Program

It is planned that around 2020, China will build a space station. Core

Module, Laboratory Cabin Module I, Laboratory Cabin Module II,

Spaceship (SZ series), and the Cargo together, will compose the whole

space station system.

2. GESSA (CSU)

GESSA (General Establishment of Space Science and Application, Chinese Academy of Sciences) was founded in 1993. On behalf of the Chinese Academy of Sciences (CAS), it participates the China’s Manned Space Engineering, acting as an organizer, coordinator and integrator of the Space Utility System of China’s Manned Space Engineering. Institutes and universities inside and outside CAS have been involved in the Space Utility System.

2. Introduction of GESSA

Chinese Academy of Sciences recently made the organization GESSA a legal person status, and it has a new name:

Technology and Engineering Center for Space Utilization,

Chinese Academy of Sciences (CSU, CAS)

(http://www.csu.cas.cn/)

Add: No 9, Deng Zhuang South Road,

HaiDian District, Beijing,100094, China

5. Utilization Planning for the

China’s Space Station

- 3rd step

• Since 2009, Under the leadership and organization of Chinese

Manned Space Engineering Office(CMSEO), GESSA began to

organize the utilization planning for the China’s Space Station.

• Hundreds of space utilization proposals suggested by more than 70

universities and institutes were received.

• Hundreds of research projects are chosen to be the candidate ones

now.

• A series of facilities and platforms were considered as the

infrastructure to support the experiments in different discipline of

space utilization.
