China ' s Chang E lunar exploration program
In January 2004, the project of China's lunar exploration was approved to set up, opening the curtain of China's deep space exploration. Exploring the Moon is a milestone of China space cause following artificial satellites and manned spaceflight. China ' s lunar exploration program is named Chang e Project . Chang e is a heroine in a Chinese fairy tale Chang e Flying to the Moon well known nationwide. Chang E Project comprises three development phases: orbiting about, landing on and returning from the Moon. The first phase of the project is to launch a lunar orbiter round the Moon by 2006 to carry out lunar exploration. The second phase is to launch a lunar rover to realize soft landing on the lunar surface from 2007 through 2010. The third phase is to send a lunar rover onto the lunar surface and then return to the Earth after exploring and collecting lunar samples. The first step is to develop and launch the lunar orbiter Chang e 1 and set up an initial system of the lunar exploration engineering at the same time.
T he scientific and engineering objectives of Chang'e 1 are as follows: The scientific objectives: 1. To obtain three-dimensional images of the lunar surface; 2. To analyze the distribution of 14 useful elements and materials below the lunar surface; 3. To probe the features of lunar soil; and 4. To explore the space environment between the Moon and the Earth , and above the lunar surface. The engineering objectives: 1. Developing and launching the China's first lunar probe; 2. Mastering the basic technologies for exploration in lunar orbit; 3. Conducting lunar scientific exploration; 4. Forming an initial space engineering system for lunar exploration; 5. Accumulating experience for later lunar exploration projects.
Cha n g E -1 is planned to be the first of a series of Chinese missions to the Moon. The spacecraft will launch in late 2007 on a CZ-3 A booster and orbit the Moon for a year to test the technology for future missions and to study the lunar environment and surface regolith. The orbiter is based on the DFH-3 Comsat bus and will have a mass of roughly 2000 kg, 150 kg of which will be the scientific payload. The payload will include a stereo camera system to map the lunar surface, an altimeter to measure the distance between the spacecraft and the surface, a gamma/X-ray spectrometer to study the overall composition and radioactive components of the Moon, a microwave radiometer to map the thickness of the lunar regolith
