Space exploration began in 1957 with the launch of the first artificial satellite.

太空探险是随着1957年第一颗人造卫星的发射而启动的。

Dynamic model of satellite is built up with astronomic method, and a short-arch forecast arithmetic of satellite orbit in short arch with single site is given, which is of high precision when only angle data is available.

本文使用了天文方法建立了人造卫星运动的数学模型，给出了一种只使用单站短弧段测角数据对人造卫星轨道进行高精度预测的算法。

In this article, we will use this novel finite particle method to analyse several important and interesting dynamics problems in neat/insighting style, including the maximum and minimum period problem of the compound pendulum oscillation, plane impact problem and the spin and precession direction problems of the oblate and prolate satellites.

本文将透过先进的有限质点法，以极简的风格来分析几种重要而有趣的动力问题，包括复摆的最大及最小周期、刚体的角碰撞问题、薄碟型人造卫星公自转反向问题以及细长型人造卫星公自转同向问题。

In most cases, the satellite will rise in the west, cross the observer's meridian, and set in the east, although satellites in a polar orbit can rise or set in any part of the sky!

大多数情况下，人造卫星自观测者的西方升起，经过中天，然后在东方落下，虽然越极轨道人造卫星可以在天空的任意部分升起和落下！

Launched by the Soviets in 1957, the Sputnik was the first satellite in the world.

苏联人在一九五七年发射的人造卫星是世界上的第一颗人造卫星。

There often exist some components or subsystems fixed at the satellite main structure in stowed configuration during launch process due to the space limitation.These components or subsystems will be deployed by using deployment mechanismwhen the satellite reached the specified orbital with designed satellite attitude.

人造卫星内许多元件於发射期间，需要以摺叠方式固定在人造卫星主结构上，而当人造卫星运转至特定的轨道点及特定的卫星姿态后，才逐一地利用展开机构将上述的结构展开至特定位置。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
