China is quickly and quietly becoming a dominant space power. Ash Dove-Jay explores what the Chinese have already achieved, what do they plan to do, and what distinguishes them from other spacefaring nations.
Next year, the Chinese National Space Administration (CNSA) marks its 25th anniversary. Since 1993 it has matured at an incredible pace. In terms of its breadth and depth of capabilities, CNSA already rivals ESA and is perhaps a decade behind NASA, entities that were established 42 and 60 years ago respectively.
The backbone of CNSA is its main contractor, the state-owned Chinese Aerospace Science and Technology Corporation (CASC). CASC has revenues in excess of £34 billion, nearly 200,000 employees, and is predominately focused on space engineering in one form or another. To give a sense of scale, that is equivalent to Lockheed Martin and Northrop Grumman combined.
Over the past decade, CNSA and CASC have successfully launched more than 150 orbital rockets, which carried around 200 spacecraft and satellites. Two of the spacecraft launched were Tiangong-1 and 2 (Heavenly Palace 1 and 2), small test-bed space stations that demonstrated a suite of technologies and capabilities, and hosted three of the five manned space missions launched. Three of the spacecraft launched were their Chang’e family of lunar probes. Chang’e-3 dispensed a lander and the very successful Yutu (Jade Rabbit) lunar rover, and Chang’e-2 went on deeper into space to conduct a flyby mission, passing within 3km of the 9.5km-wide asteroid 4179 Toutatis.
China has also brought online major space based infrastructure, including satellite television, weather forecasting and – most notably – its own GPS service using the BeiDou navigation satellite system. Though originally looking to cooperate with Europe on the Galileo satellite navigation programme, China, dissatisfied with its level of involvement, in 2006 decided to develop its own system independently.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
