2013年12月2日凌晨,骨灰级航天控果果不远千里抵达西昌卫星发射中心,会同数千名游客齐聚观景台.现场的大多数游客都是一等一的航天发烧友或科技爱好者,对我国探月工程了如指掌.这次果果有幸现场观看“嫦娥三号”的发射过程感到无比开心和激动!我国载人探月三部曲“绕、落、回”中的“落月”工程完美收官,标志着中国载人航天事业已进入“嫦娥工程”二期阶段.果果结合她所掌握的航天技术中的化学知识,引导同学们共同了解我国探月工程中的几个焦点问题.【问是一】月球到地球的平均距离约为3.8×10~5km,为了满足运载过程中的能量需求,运载火箭所用的燃料是什么?“嫦娥三号”是我国航天领域迄今最为复杂、难度
In the early hours of December 2, 2013, astronautic astronauts arrived at the Xichang Satellite Launch Center not far from where thousands of tourists gathered at the observation deck. Most of the tourists on the scene are first-class space enthusiasts or technology lovers Who are well aware of the lunar exploration project in our country and were fortunate enough to watch the launch of Chang’e III this happy fruit and excitement! The Trilogy of Manned Exploration Moon in Our Country The project of “Lost Moon” ended the second phase of the project, marking that China’s manned space project has entered the second phase of “Chang’e Project.” Fruit and fruit combined with the chemistry knowledge in aerospace technology at its disposal to guide the students to understand together Q: Is the average lunar-to-earth distance about 3.8 × 10 ~ 5km, in order to meet the energy needs of the carrying process, what is the rocket fuel used? “Chang’e No. 3 ”is by far the most complicated and difficult space in China’s aerospace field
