NASA英文主题PPT文稿
When it comes to NASA, I believe we are not unfamiliar to it. NASA often appears in many of the Hollywood science fiction movies, for example, Star Wars, Galaxy guard, Gravity and so on. The NASA in the film is always the omnipotent, but what does the NASA in the real world look like? Next let me to lead you to uncover the mystery of NASA.
谈到NASA，相信大家对它并不感到陌生。NASA经常出现在众多好莱坞科幻电影当中，比如，星球大战，银河护卫队，地心引力等等。但是电影中的NASA 总是显得无所不能，那么现实世界中的NASA是什么样子的呢？接下来让我来带领大家揭开NASA的神秘面纱。

美国国家航空航天局（NASA）是美国联邦政府行政部门的一个独立机构，负责民用航天计划以及航空航天研究。国家航空航天局自成立以来在探索空间方面取得了许多成就。
?X-15 rocket plane (1959–68)
The X-15 set speed and altitude records in the early 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. X-15设置速度和高度记录在20世纪60年代初，到达外层空间的边缘，并返回用于飞机和航天器设计的有价值的数据。
Project Mercury (1959–63)
Project Mercury started in 1958 as NASA's inheritance of the U.S. Air Force's Man In Space Soonest program objective to make the first single-astronaut flights into Earth orbit.
项目水星于1958年开始，作为美国航空航天局的继承美国空军的太空人计划目标，使第一个单宇宙航空器飞行到地球轨道。
Project Gemini (1961–66)
Based on studies to grow the Mercury spacecraft capabilities to long-duration flights, developing space rendezvous techniques, and precision Earth landing。
根据将水星航天器的能力发展成长时间飞行，发展空间会合技术和精确地球着陆的研究
Project Apollo (1961–72)
The Apollo program was the third human spaceflight program carried out by the NASA with President John F. Kennedy's national goal of "landing a man on the Moon and returning him safely to the Earth".

Skylab was the United States' first and only independently built space station. It included a laboratory for studying the effects of microgravity, and a solar observatory.
Skylab是美国第一个也是唯一独立建造的空间站。它包括一个研究微重力效应的实验室和一个太阳观测台。
Space Shuttle program (1972–2011)
The Space Shuttle became the major focus of NASA in the late 1970s and the 1980s. Planned as a frequently launchable and mostly reusable spaceship across from space
and earthInternational Space Station (1993–present)
航天飞机成为美国航天局在20世纪70年代末和80年代的主要焦点。计划作为一个经常可发射和大多数可重复使用的太空飞船从空间和地球
The ISS programme is a joint project among five participating space agencies: NASA, Roskosmos, JAXA, ESA, and CSA. As the largest artificial body in orbit, the ISS can often be seen at the appropriate time with the naked eye from Earth.
ISS计划是五个参与空间机构之间的联合项目：NASA，Roskosmos，JAXA，欧空局和CSA。作为在轨道上最大的人造物体，ISS通常可以在适当的时候用肉眼从地球上看到。
In all,NASA in the real world is not as powerful as the NASA in the film, and there are many difficulties to be overcome in the exploration of space.现实世界中的NASA并没有像电影中的NASA那样的无所不能，在探索太空的路上，人类需要走的路还有很多。
