2003年10月16日，中國第一架載人宇宙飛船安全返回地面。這標志著中國成為世界上第三個成功將人類送上太空的國家。對于中國來說，這是在航天科技上的巨大突破。與無人飛船相比，載人飛船因有人類的直接參與而在技術上有一些特殊要求，這包括環境控制、應急救生、人工控制、安全返回、高可靠性等。
答案
The safe return of China’s first manned spaceship on October 16, 2003 has made China the third country in the world that has successfully sent a man into space. For China, this has been a huge breakthrough in space technology. Unlike the unmanned spaceship, the manned spaceship, which involves direct participation of human beings, must meet some special technological requirements, including environmental control, emergency lifesaving, manual control, safe return, high reliability, etc.
