The lunar-landing is the continuation of manned spaceflight engineering. Comparing with the manned airship engineering, it requires more credibility and sweepingness, and it needs more funds. On the basis of China´s achievements and foreign countries´ experiences, the paper brings forward the idea of using the existing transportation technology to sent the launch vehicles and cosmonauts to the near-earth orbit in batches, assembling the components together on the space-launch platform, and then launching them to the moon. The paper also discusses the space-launch platform and the launching way.
