China's first lunar orbiter was launched into space today and is expected to reach orbit around the Moon by the beginning of November. The satellite, named Chang'e 1, after a Chinese goddess, will spend a year in orbit to test the technology and to study the lunar environment and its surface features in preparation for future missions. China's long-term mission plans for the Moon include sending an unmanned rover in 2012 and, by 2020, a manned mission to assemble a permanent space lab.
According to NASA's National Space Science Data Center (NSSDC), to obtain scientific objectives, the Chinese satellite will include five types of instruments: a stereo camera system, to map the lunar surface; an altimeter, to measure the topography; 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; and a system of space environment monitors, to collect data on the solar wind and near-lunar region.
The launch of the lunar orbiter signifies an important step in China's hope of gaining a more substantial presence in space, but it also has many experts and analysts wondering whether a space race may be looming. The Chinese government and the chief commander of the orbiter project have made official statements saying that they have no intention of engaging in a space race with other Asian countries, including Japan and India, or with the United States and Russia.
Japan launched a lunar orbiter in September, and the United States and India have plans to launch lunar orbiters in 2008.
