如果有个漫游机器人在火星表面有信息传回地球，机器人会先将数据保存起来，等到卫星绕到了可以接收信号的轨道范围再发送出去；

For example, if a rover on Mars needs to send data to Earth, it would first need to store the data until it was within range of an orbiting satellite.

结束当天工作之前，漫游车会向“火星奥德赛”人造卫星发送照片以及他们所在地点的其他数据，卫星随后将信息转回任务控制中心。

Before shutting down each night, the rovers send pictures and other data of their positions to an orbiter called Mars Odyssey, which relays them back to mission control.

该飞行器虽然计划在火星上漫游数日，并仅进行3个月的信息传送，但是实际上探路者漫游了一个月，信息传送工作也进行了1年。

Although it was designed to roam the planet for a few days and transmitinformation for only three months, the Pathfinder roamed for a month andcontinued to send information for a year.
