7月5日至7日,2019年软件定义卫星高峰论坛在山东日照举行。据报道,中国将在2020年探测到火星,并通过火星卫星,火星登陆器和火星联合探测火星,而目前的火星探测器已经准备就绪。

火星探测的主要科学问题是探测火星上的生命活动信息,并有望在该领域取得突破;其次是本体科学研究,如火星磁层,电离层和大气探测以及环境科学;三是探索火星长期转型和未来建立第二个人类栖息地的前景。

欧阳自远在论坛上发表演讲《迎接第一个100年,中国的深空探测》。支付一个机翼飞行太阳射击

在论坛上,欧阳资源介绍说,中国将在2020年探测到火星。人类已经探测到火星45次,但只有18次成功,成功率仅为40%。

“为什么?火星探测并不意味着什么时候你想要发射。它只有26个月的机会。你失去了这个机会,对不起,两年零两个月再次发射,否则你无法获得火星。“

欧阳自远介绍说,地球是在太阳周围365天,而火星在太阳周围约有687天。 “有时候地球位于太阳的一侧,火星位于太阳的另一边,你无法到达火星。所以一定要赶上某个关键时刻,也就是说,当地球有一定的时候与火星的角度,在地球上发射。探测器只能飞到火星轨道,至少持续七个月。“

He introduced that this time China explored Mars, "There will be a Mars satellite flying around Mars, a Mars lander, and a Mars. These three things realize the joint exploration of Mars in the world, and the Mars is ready." ."

Pieces and the environment, the origin of life and the exploration of extraterrestrial life.

The second is to accumulate data for Mars ontology science. Including Mars magnetosphere, ionosphere and atmosphere detection and environmental science; Martian topography and division; Mars surface material composition and distribution, geological features and tectonic division; Mars internal structure, composition, intrinsic magnetic field detection; Mars and comparative planet Learning, the origin and evolution of Mars, the origin and evolution of the solar system.

The third is to explore the long-term transformation of Mars and the prospect of establishing a second habitat for mankind in the future. Its overall goal is to serve the sustainable development of human society.

"Scientists are worried about the future of mankind, because our planet is subject to too many natural threats, coupled with some of human behavior, the future is likely to destroy the earth can not be liable. So we must find an object in the solar system To explore whether it can be turned into a second earth, allowing humans to move a lot to it. At present, the only possible celestial body is Mars."

Ouyang Ziyuan introduced that there are many ancient river beds on the surface of Mars, which proves that Mars used to have rivers. The northern part of Mars is a large ocean.

xx火星研究中的一个重要问题是火星的脱水机制:火星上的水是否会流失?还是冻结后埋在地下?他说,之前的观测和理论研究表明,太阳风与火星大气之间的相互作用只能导致其表面30%的水分流失(McKay和Stoker,1989)。

欧阳自远说,他没有找到任何(火星)生命存在的证据。今天,国际会议,火星最大的理想是改造火星,为人类,保持自己的物种。科学的任务是为人类命运共同体的未来创造更多的可能性。

他说:“通过几个世纪的卓越努力,人类已经将火星,一个荒芜的星球变成了一片蓝天,绿色平原,蓝色湖泊和生态环境的新世界。地球 - 火星将成为一个人类社会。姊妹社区继续发展。“
