Chinanews, Beijing, Oct 17 – Chang'e No. 1 satellite and the carrier rocket that will be used to send Chang'e into space have been placed in the Xichang Satellite Launching Center. At present, the satellite has been injected with enough fuels and has been connected to the carrier rocket, said Zhang Qingwei, director of the Commission of Science, Technology and Industry for National Defense, on Tuesday.In the next step, scientists will test to make sure that the satellite, the carrier rocket and all the launching system can function well. Since this will be the first time for China to send a satellite to the moon, some tasks which will be carried out in the moon will be difficult to be simulated on the earth. The moon is located some 380,000 kilometers away from the earth, it might be difficult for scientists to monitor exactly the flying speed, the location and the shape of the satellite in space during the launch. “This requires that scientists should have a high skill in accomplishing the tasks, ” Zhang said.To cite an example, Zhang said when the satellite shifts from the earth orbit to the moon orbit, scientists should be able to make the satellite stop at the last point so that it can make the transition correctly. If scientists can't do it in time, the satellite might then fly out of the moon orbit. In order to make sure that everything can go well as planned, scientists are still doing research about this.“In order to avoid these risks, we have devoted more efforts to analyzing the possible technical risks and we have to work out several hundred different schemes to counter them. At the same time, we will try to make use of some global space network resources to make sure that the launching can be a success,” Zhang noted.“Although there might be great risks, we are still confident that the launching can be successful. We hope that people from all walks of life can understand us and support our work,” Zhang said.Three years ago, China approved Chang'e No. 1 moon probe project. Over the past three years, Chinese scientists and engineers have worked hard to obtain several key technologies related with the project. The Chang’e No.1 moon probe satellite is expected to be launched in late October, Zhang said.
