嫦娥五号“挖土”归来！中国探月工程嫦娥五号任务取得圆满成功
胡喆 8 小时前 新华社北京12月17日电（记者胡喆、彭韵佳）12月17日凌晨，嫦娥五号返回器携带月球样品，采用半弹道跳跃方式再入返回，在内蒙古四子王旗预定区域安全着陆。 随着嫦娥五号返回器圆满完成月球“挖土”，带着月球“土特产”顺利回家，北京航天飞行控制中心嫦娥五号任务飞控现场旋即成为一片欢乐的海洋，大家纷纷欢呼、拥抱，互致祝贺。 探月工程总指挥、国家航天局局长张克俭宣布：“探月工程嫦娥五号任务取得圆满成功！” 历经23天，嫦娥五号闯过地月转移、近月制动、环月飞行、月面着陆、自动采样、月面起飞、月轨交会对接、再入返回等多个难关，成功携带月球样品返回地球，完成了这次意义非凡的太空之旅。 “嫦娥五号任务既是收官之作，更是奠基之作。”嫦娥五号任务新闻发言人、国家航天局探月与航天工程中心副主任裴照宇表示，嫦娥五号任务是我国探月工程“绕、落、回”三步走中“回”这一步的主任务，成功实现了月球表面采样返回。 探月工程是《国家中长期科学和技术发展规划纲要（2006-2020年）》确定的16个国家科技重大专项之一。自立项以来，国家航天局组织全国2000多家单位、数十万名科技工作者，团结协作、集智攻关，高质量高效益完成六次探测任务，实现“六战六捷”。 揽月而归，踏梦而行。作为我国复杂度最高、技术跨度最大的航天系统工程，嫦娥五号任务实现了我国首次月面采样与封装、月面起飞、月球轨道交会对接、携带样品再入返回等多项重大突破，其成功实施标志着我国探月工程“绕、落、回”三步走规划如期完成。（完）
欢迎!嫦娥五号回家了! Commentary: China's new samples a fresh start for lunar research, space exploration Quan Xiaoshu,Yu Fei 3 小时前  © Provided by N.C.N. LimitedTechnical personnel shake hands to celebrate the landing of the return capsule of China's Chang'e-5 probe at Beijing Aerospace Control Center in Beijing, capital of China, Dec. 17, 2020. (Xinhua/Jin Liwang)by Xinhua writers Quan Xiaoshu, Yu Fei BEIJING, Dec. 17 (Xinhua) -- The successful re-entry and landing of the Chang'e-5 capsule on Thursday has enabled China to obtain its first lunar samples, marking a new start for the moon and planetary research.The major goal of Chang'e-5 was to get things back. This will improve understanding of the state, temperature, material content and other important information of the moon. No matter how far China goes into the space, it always stays true to its original target -- unveiling the secrets of the universe and contributing to humanity's peaceful use of space.The Chang'e-5 probe, comprising an orbiter, a lander, an ascender and a returner, was launched on Nov. 24. Its lander-ascender combination touched down on the north of the Mons Rumker in Oceanus Procellarum, also known as the Ocean of Storms, on Dec. 1, where it used drills to collect subsurface samples and a robotic arm to grab samples directly from the surface. The landing site was wisely picked. Mons Rumker, never sampled before, is geologically younger than the sampling areas of the U.S. and the Soviet missions. Scientists believe the new samples could help fill an important gap in their understanding of the moon's volcanic activity and evolution.Adopting a complicated technological approach, the Chang'e-5 mission overcame many technological challenges, including China's first spacecraft liftoff from an extraterrestrial body and first unmanned rendezvous and docking in lunar orbit. China views these efforts as part of the world's lunar exploration. It chose a different landing site and is promising to share its samples to enrich knowledge about the moon. Some foreign scientists have shown special interest.The exploration is not for commercial purposes, but for international scientific research. Humanity shall explore the moon together, as it will eventually involve large projects requiring international cooperation. The mission will lay an important foundation for China's future manned lunar landing and deep space exploration. Next, China plans to explore the South Pole of the moon for water-ice resources and is considering an initiative for joint efforts to build an international lunar research station.Rocket pioneer Konstantin E. Tsiolkovsky once said Earth is the cradle of humanity, but one cannot remain in the cradle forever. Almost a century later, humans have taken only a few steps forward into the space, let alone the vast universe. No one knows what risks Earth will face in the future, and a "backup planet" is yet to be found. It might be too remote to think about problems like a doomsday crisis and interstellar migration, but it will be promising for humanity if competent and responsible countries, including China, continue to develop space technologies and promote space exploration.
