伊拉克拥有“毁灭性武器”是一个连美国总统都已经承认的弥天大谎;最近因特网又爆出一段81分钟的美国本土视频——“9·11恐怖大骗局”。揭露了至少42个铁证,证明这一起骇人听闻的事件竟然是美国利益集团一手策划的惊天阴谋!现在,美国再一次故伎重演,为了堵住美国纳税人的嘴,为了掩饰美国在月球领域寻水的失败,竞又编造出一起所谓的“月球水体”的闹剧。 相似文献

1969年11月14日。当“阿波罗12”号飞船飞向月球时,遭遇了若干不明飞行物。两个UFO“陪伴”飞船飞行了大约24万千米的距离。那次登月任务非常成功,登月舱安全地降落在了月球风暴海附近。“阿波罗12”号的任务指挥官查尔斯·康拉德后来无法隐藏他心中的快乐:“我们非常幸运!它们待我们真客气!” 相似文献

水冰作为月球的重要资源,是未来月球科研站以及月球基地建设和运行的基本保障,开展月球水冰资源综合开发技术研究是目前各航天大国的关注热点之一。本文调研了有关月球水冰的探测和研究成果,阐述了月球水冰的赋存状态与分布特征,详细分析了月球水冰资源在开采提取、分离纯化、储存运输和分解利用等环节的技术方案,并简要评述了各个方案的优缺点。结合中国未来国际月球科研站的建设规划与美国以建立月球基地为目标的阿尔忒弥斯(Artemis)计划,评价分析了适宜开展月球水冰资源综合开发的地区和可行的技术方案,为中国在月球两极地区的水冰资源开发利用方案提供参考。 相似文献

在40年前,美国宇航员阿姆斯特朗在月球上跨出第一步时说:“这是我跨出的一小步,却是整个人类跨出的一大步。”毫无疑问,人类迈向太空的步伐正在加快,这不,有人已经提出新的计划——移民到火星上去吧! 相似文献

In accordance with the United Nations Outer Space Treaties [United Nations, Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, UN doc A/RES/34/68, resolution 38/68 of December 1979], currently maintained and promulgated by the Committee on Space Research [COSPAR Planetary Protection Panel, Planetary Protection Policy accepted by the COSPAR Council and Bureau, 20 October 2002, amended 24 March 2005, http://www.cosparhq.org/scistr/PPPolicy.htm], missions exploring the Solar system must meet planetary protection requirements. Planetary protection aims to protect celestial bodies from terrestrial contamination and to protect the Earth environment from potential biological contamination carried by returned samples or space systems that have been in contact with an extraterrestrial environment. From an exobiology perspective, Mars is one of the major targets, and several missions are currently in operation, in transit, or scheduled for its exploration. Some of them include payloads dedicated to the detection of life or traces of life. The next step, over the coming years, will be to return samples from Mars to Earth, with a view to increasing our knowledge in preparation for the first manned mission that is likely to take place within the next few decades. Robotic missions to Mars shall meet planetary protection specifications, currently well documented, and planetary protection programs are implemented in a very reliable manner given that experience in the field spans some 40 years. With regards to sample return missions, a set of stringent requirements has been approved by COSPAR [COSPAR Planetary Protection Panel, Planetary Protection Policy accepted by the COSPAR Council and Bureau, 20 October 2002, amended 24 March 2005, http://www.cosparhq.org/scistr/PPPolicy.htm], and technical challenges must now be overcome in order to preserve the Earth’s biosphere from any eventual contamination risk. In addition to the human dimension of the mission, sending astronauts to Mars will entail meeting all these constraints. Astronauts present huge sources of contamination for Mars and are also potential carriers of biohazardous material on their return to Earth. If they were to have the misfortune of being contaminated, they themselves would become a biohazard, and, as a consequence, in addition to the technical constraints, human and ethical considerations must also be taken into account. 相似文献

美国东部时间2016年9月8日,美国航空航天局(NASA)的“起源、光谱释义、资源识别、安全、风化层”探测器(OSIRIS-REx,以下简称“奥西里斯”探测器)成功发射,其有两方面最为突出:一是将小行星贝努作为探测目标是经过了许多科学家的研究和精密论证,科学目标选得非常好;二是“接触即离”(TAG)的取样方式取得了很大的突破,但也具有巨大的风险性,该方式可能成为未来探测小行星的重要方式,方式新颖,无可挑剔。 相似文献

The human exposure in space depends on the three factors: the flight trajectory, its date and duration and the cyclogram of the cosmonaut's activities. In the near-Earth orbits the daily dose varies within the limits of (1.5-5.0) 10(-4) Gy day-1 and greatly increases if the altitude increases. The mean daily quality factor is 1.6-2.0. Strong solar proton events in the orbits with the inclination of < 52 degrees result in the dose rate increase up to 2-3 cGy day-1. On the surface of the orbital spacecrafts the daily dose reaches 2 Gy. The neutron dose depends on the shielding mass distribution varying within the limits of 6%-30% of the charged particles dose. In deep space the dose is mainly formed by the galactic and solar cosmic rays(GCR,SCR). Behind the shielding of 2-3 g cm-2 Al the GCR dose varies in the range of (20-30) 10(-5) Gy day-1. The SCR dose can reach hundreds of cSv. 相似文献

Looking at the chance of the next apparition of the Halley comet in 1986, ISAS decided to send a first Japasanese interplanetary spacecraft for the study of cometary hydrogen coma and solar wind. The Planet-A spacecraft which carries VUV imaging camera and solar wind plasma analyser will be launched in August 1985 and flyby the Halley comet in early March 1986 with the distance of several million kilometers from the comet nucleus. This mission is not only self-consistent but collaborative with other space mission as well as earth-bound observations. In the present paper, the Planet-A mission to Halley is described with brief explanation of the spacecraft. 相似文献

小行星是太阳系内类似行星的一种天体,环绕太阳运动,但体积和质量比行星小得多。至今为止在太阳系内已经发现了70多万颗小行星,不过只有少数的小行星直径大于100千米。最大的小行星是谷神星,直径约950千米。不过近年来又发现一些小行星比谷神星还要大,如2004年发现的一颗小行星直径甚至达到1800千米。直径超过240千米的小行 相似文献
