Chinese press, thousands of tourists and space experts from Japan, Germany, Italy and other countries have gathered at China’s Xichang Satellite Launch Center in southwestern Sichuan Province on Tuesday, October 23 to witness the historic moment-the launch of the nation’s first moon orbiter (人造卫星), which is scheduled to take place at 6:05 p.m.on Wednesday．

Space center experts were worried earlier in the day when Xichang experienced an unexpected rainfall from about 4:05 a.m．till 7:10 a.m．on Wednesday, but they were able to breathe a sigh of relief when the weather cleared．Both national and local meteorological observatories (气象台)forecast cloudy weather for the launch site on Wednesday afternoon．However they said they believed it would not affect the launch mission, an opinion which was shared by technological staff at the site．     

Local villagers within a radius of 2.5 km of the launch site and under the trajectory(轨道) of the carrier have been told to move to safe areas two hours prior to the planned launch．Tourists have been charged 800 yuan (105 U.S.dollars) to witness the launch of China’s first lunar satellite．A local travel agency has said that the two observation platforms are capable of holding 2,000, but it is not known how many people paid for the chance．

The moon orbiter, Chang’e-1, named after a legendary Chinese goddess who flew to the moon, and the carrier Long March 3A have passed all pre-launch tests．     

China hopes to become the 17th nation to join the International Space Station (ISS) project, and carried out its first piloted space flight in October 2003, making it only the third country in the world after the Soviet Union and the United States to have sent men into space．In October 2005, China completed its second manned space flight, with two astronauts on board．

One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states.” said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.

In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 “Toubon law” in France, but the idea has been copied in many countries since then. Such efforts to govern language use are often dismissed as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.

It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but there has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.

The need to protect national languages is, for most western Europeans, a recent phenomenon—especially the need to ensure that English does not unnecessarily take over too many fields. Public communication, education and new modes of communication promoted by technology, may be key fields to defend.
