Galileo Spacecraft

Galileo is the fifth spacecraft to visit Jupiter. It contains ten research instruments on a 15 ft long, 5200 lb framework. It launched a 744 lb, 34 inch diameter probe to Jupiter . The probe carried six instruments.

伽利略号是第第五艘访问木星的航天器。它搭载了十种科研仪器，这些仪器安装在一个15英尺长、重5200磅的框架上。它向木星发射了一个重744磅、直径34英寸的探测器。探测器携带了六种仪器。

The Galileo spacecraft is powered by a 500 watt plutonium power plant. It's rendevouz with Jupiter puts it too far from the sun to be effectively solar powered.

伽利略探测器由一台500瓦的钚动力装置供电。它与木星会合时，距离太阳太远，无法有效进行太阳能供电。

Galileo was launched in 1989 on a mission which would take it into orbit around Jupiter. Galileo passed asteroid Gaspra at 17,895 mph and passed within 1000 miles of the chunk of rock and iron. The signal took 23 minutes to travel the 255 million miles to earth. Two to 13 months were required to see the images because of the big antenna's failure. It passed closest to earth again in November 92 where it could use small antenna.

伽利略号于1989年发射，其任务是将其送入木星轨道。伽利略号以每小时17,895英里的速度飞过小行星Gaspra，并在其附近1000英里以内飞过。信号需要23分钟传送到地球。由于大型天线的故障，需要两到十三个月才能看到图像。它再次最接近地球是在1992年11月，当时它可以使用小天线。

Galileo's Jupiter mission was to launch a probe into the Jupiter atmosphere and then orbit the planet. The probe was designed to withstand pressures of at least 10 Earth atmospheres and was supposed to transmit information about the Jupiter atmosphere's composition, structure, hydrogen-helium ratio, lightning activity, thermal balance, and size of cloud particles.

伽利略号探测器的任务是将一个探测器送入木星大气层，然后绕木星轨道运行。该探测器设计成能够承受至少10个地球大气压，并且应传输关于木星大气层的成分、结构、氢-氦比例、闪电活动、热平衡以及云粒子大小的信息。
