  继上次“LIA大咖聊”活动结束后,同学们反响十分热烈,纷纷表示意犹未尽,想要更多的了解太空探索方面的知识。为了丰富同学们在疫情期间的课外活动,拓展科技视野,增强民族自豪感。2022年12月8日,我们荣幸邀请到了中国运载火箭技术研究院的现任高级工程师——刘元春博士来到本次“LIA大咖聊”,为同学们带来火星探索方面最前沿的知识。

  After the last "LIA Stars Talk", our students responded enthusiastically and expressed their desire to know more about space exploration. To furthur enrich students' extracurricular activities during the time of COVID-19, expand their scientific and technological vision and enhance their national pride, on December 8, 2022, we were honored to invite Dr. Liu Yuanchun, the current senior engineer of the China Academy of Launch Vehicle Technology, to our Talk to bring the most cutting-edge knowledge of Mars exploration to the students.

  刘博士首先为同学们讲解了人类坚持火星探索的理由:通过对比地球和火星,可以发现火星作为太阳系中同时具有有岩石表层和大气层的类地行星,有可能和地球一样存在孕育生命的条件,同时它相比其他太阳系中的行星离地球更近,是人类探索地外生命和宜居星球的最佳去处。

  Dr. Liu first explained the reason why we insist on Mars exploration: by comparing Earth and Mars, we can find that Mars, as an earth-like planet in the solar system having both a rock surface and an atmosphere, Mars may have the same conditions as Earth to breed life. At the same time, it is closer to the Earth than other planets in the solar system, and is the best place for humans to explore possible extraterrestrial life and habitable planets.

  紧接着,刘博士与同学们分享了人类探索火星的历程。如同探月一样,人类对火星的探索也分为三个阶段:1960-1970年,火星探测器仅能完成拍照和探测大气参数等简单任务;1970-1990年,探测器可以环绕火星旋转并着陆进行简单的探测活动;1990年至今,探测器可以可以完成样本采集等复杂探测活动,并开始寻找水和生命存在的迹象。

  Dr. Liu also shared with students the course of human exploration of Mars. Like lunar exploration, human exploration of Mars can also be divided into three stages: from 1960 to 1970, Mars probes could only complete simple tasks such as taking pictures and detecting atmospheric parameters; From 1970 to 1990, the probe could orbit Mars and land for simple exploration activities; Since 1990, the detector has been able to complete complex detection activities such as sample collection, and began to look for signs of water and life.

  最后,刘博士着重介绍了中国在火星探测活动中的重要成就。随着苏联解体和中国火箭运载技术的提高,中国接替苏联,和美国一起成为了火星探索领域的“主角”。“天问一号”火星探测器的成功发射标志着我国首次实现地火转移轨道探测器发射;首次实现行星际飞行;首次实现地外行星软着陆;首次实现地外行星表面巡视探测;首次实现4亿公里距离的测控通信;首次获取第一手的火星科学数据,是我国在航天领域又一次伟大的突破。

  At the end, Dr. Liu highlighted China's achievements in Mars exploration. With the disintegration of the Soviet Union and the improvement of China's rocket technology, China succeeded the Soviet Union and became the "leading role" in the field of Mars exploration together with the United States. The successful launch of the "Tianwen 1" Mars probe marked the first time that China has realized the launch of the Earth fire transfer orbit probe; The first interplanetary flight; The first soft landing of an extraterrestrial planet; The first time to realize the inspection and detection of the surface of extraterrestrial planets; The first time to realize the measurement and control communication of 400 million kilometers and the first-hand Martian scientific data for the first time which was another great breakthrough in China's space exploration.

  活动结束后,本次活动的组织者、学生成长中心的升学指导负责人赵明老师和同学们一起对刘博士表示了衷心的感谢。参与活动的10年级同学也收获颇丰,哈佛班的田同学说道,这次活动唤醒了她对宇宙的兴趣,让她看到了人类面对航天探索的各种困难时的勇气,更加让她自豪的是我国的火星探索技术已经达到了可以和美国一较高下的地步,在疫情面前科学家们也没有停下前进的步伐,这种不畏艰难、坚持到底的信念深深打动了她,在学习到航天知识的同时增强了民族自豪感,如同注入了一针强心剂。让我们一起期待下一次的“LIA大咖聊”,找到自己在世界的位置!

  After the activity, Ms. Ming Zhao, Head of COG Office and the organizer of the activity, together with our students expressed their heartfelt thanks to Dr. Liu. The 10th grade students who participated in the activity also gained much from this sharing. Tian from Harvard class said that this talk had awakened her interest in Space and showed her the courage of humans when facing various challenges in space exploration. What made her more proud was that China's Mars exploration technology had reached a level that is comparable to the United States, and scientists had not stopped moving forward in the face of COVID-19. She was deeply moved by the belief of persistency and never ending spirit. While learning more aerospace knowledge, it also enhanced her pride for her nation. Let's look forward to the next "LIA Stars Talk" and find our place in the global world!
