Research Framework and Progress
in High-Technology R&D
Space Science and Technology
CAS has proposed and is actively engaged
in a series of important space missions,
such as the Chinese Manned Space Engineering
(CMSE) program and the Chinese
Lunar Exploration Program (CLEP). CAS
also undertook and successfully completed
the task of payload development for a series
of application satellites for the study of
meteorology, the environment, the ocean,
and land resources.
As the leading organization for the Space
Utility System of the Chinese Manned Space
Engineering Program, CAS carries out scientific
experiments and related research on
the Tiangong (TG)-1 and Shenzhou (SZ)-8
space platforms. On TG-1, space material
science facilities and space environment
monitors were installed. A colloidal crystal
growth experiment was performed and, for
the first time in China, the image data remotely
transmitted. In the reentry capsule
of SZ-8, 17 space life science experiments
were conducted in a cooperative Sino-German
project, including 10 Chinese, six German,
and one joint experiment. This project
is under the framework of a governmental
agreement between the two countries, to
conduct the space life science experiments
in a German incubator loaded on the SZ-8
spacecraft. The experiments cover studies
on animal, plants, and microbial materials.
In June 2011, Chang’e (CE)-2 completed
its lunar exploration mission. On August 25
of that year, it entered into the Lagrangian
2 point orbit to carry out extended tests
and outer space environment exploration.
On September 15, it sent back the first scientific
data from over 1,720,000 km away.
Two months later, full coverage high quality
moon maps and images with seven-meter
resolution had been generated and validated
by experts. The data quality and image
resolution were of the highest standard
Research
In order to meet the national strategic demands and keep abreast of global advances in science and technology, the
mission of high-technology research at the Chinese Academy of Sciences (CAS) is to carry out strategic, innovative, and
forward-looking studies, promote breakthroughs in key technologies and integrated innovation, provide systematic solutions,
and consequently make contributions to the development of information technology, space technology, advanced
manufacturing, new materials, and energy-related technologies.
Since the implementation of the Knowledge Innovation Program in 1998, a long-term approach for Development Strategy
Research has been formulated in the field of high technology at CAS. Two guiding plans, the 11th Five-Year Plan
(2006–2010) and the 12th Five-Year Plan (2011–2015), are already in place. Inspired by the Innovation 2020 Program, a
list of Strategic Priority Research Programs such as the Strategic Priority Research Program in Space Science, have been
prioritized and a number of high-technology R&D centers have been established.
and the image quality, data consistency, and data integrity allowed for the
creation of some of the best digital maps of the moon to date. CAS scientists
played integral roles in the mission, including the data retrieval and
processing, very long baseline interferometric navigation, image generation
and analysis, and other landmark scientific achievements.
A series of significant achievements have come out of the space environment
exploration program for the Meridian Project. The Meridian Project,
which was initiated by the National Space Science Center, an institute
within CAS, included 95 observation facilities already in existence. The first
sounding rocket was launched on May 7, 2011. In initial trial operations,
empirical space observation data has been collected and analyzed from
over 3.5 million data points. Preliminary space weather observation data
were also collected, such as an intense disturbance of the ionosphere
detected by the Meridian Project on March 11, 2011 following the Japan
earthquake. The effect of solar storms on the geospace environment above
China has been observed many times, with the most intense magnetic
storm since 2007 observed on August 6, 2011. Space weather forecasts
and real-time warnings based on data from the Meridian Project contributed
to the successful launches of both TG-1 and SZ-8.
Information Technology
Progress has already been made in applied technologies such as All-IP
networks, micro-nano sensors and systems, wireless sensor networks,
broadband wireless mobile multimedia, high performance computing, and
intelligent robots.
China’s first manned 7,000 m submersible, “Jiaolong,” successfully finished
its 5,000 m undersea trial in July 2011. Its maximum depth capacity
of 5,188 m is a record for China-made manned submersibles. As one of
the major developers of the “Jiaolong,” CAS was in charge of the R&D and
technical support of the acoustics and control systems. The function and
performance of the communication sonar out-performs its global peers.
Both seabed topography and side-scan sonar pictures can be obtained using
the high resolution bathymetric side-scan sonar, internationally regarded
as of the highest quality. The control system has sophisticated functionality,
including cruise control, navigation, and the integrated display of information.
The control parameters of the submersible can be adjusted in real time
using dynamic modeling. Accurate dynamic positioning—functionality not
previously seen in manned submersibles of this kind—and automatic long
distance cruising are included (Figure 1).
The Institute of Process Engineering (IPE) has been devoted to the
study of multiscale phenomena for nearly 30 years, with a particular focus
on meso-scales at different levels, namely material, reactor, and system.
A unique stability-constrained meso-scale modeling approach, the
EMMS Paradigm, was developed and gradually refined (1–2), applying the
