今年2月,我在燕山脚下的航天城,见到了研制“神舟”飞船的总指挥、39岁的袁家军。在飞船研制中心的总装车间,我看到了一个按1:1比例复制的“神舟”飞船模型,模型分为三段,袁家军介绍说:中段叫返回舱,是飞船的控制指挥中心;前段叫轨道舱,是航天员生活和做实验的地方;后段叫推进舱,为飞船在轨道飞行和返回地面时提供能源和动力。我见到的返回舱并不大,外观非常像一口平放的大钟,舱里是密密麻麻的仪器仪表。轨道舱远看是一个较大的圆柱体,里面就是一个小型“空间实验室”。今年1月,“神舟2号”返回舱落地,轨道舱仍留在太空翱翔。新华社曾报道说,轨道舱里载有一种叫“太阳伽玛射线探测器”的仪器已向地球发回信息。专家透露:太阳伽玛射线频繁出现,会引起无线电通讯中断,并会给太空行走的航天员带来生命危险。太阳伽玛射线探测器要完成的任务就是测出这种射线的活动规律,这对预防灾害有很大的作用。这种探测在我国是
In February this year, I was at Space City at the foot of Yanshan and saw the commander-in-chief of the “Shenzhou” spacecraft and 39-year-old Yuan Jiajun. In the assembly workshop of the spacecraft research center, I saw a “Shenzhou” spacecraft model copied in a ratio of 1: 1. The model is divided into three sections. According to Yuan Jiajun, the middle section is called the return capsule and is the control command center of the spacecraft. Called the orbital module, is where the astronauts live and experiment; the latter is called the propulsion module, which provides energy and power for the spacecraft to fly in orbit and return to the ground. I see the return capsule is not large, looks very much like a flat clock, the cabin is dense instruments. The orbital compartment is a large cylinder from afar, which is a small “space laboratory”. In January this year, “Shenzhou 2 ” returned to the landing, orbiting space still remain in space. Xinhua News Agency has reported that the orbital cabin contains a device called “Solar Gamma Ray Detector” that sends back information to Earth. Experts said: The frequent occurrence of solar gamma rays can cause radio interruptions and threaten astronauts in space. The task that the sun gamma ray detector must accomplish is to measure the law of activity of this kind of ray, this has very great function in disaster prevention. This exploration is in our country
