这些卫星位于一个十分特殊的轨道，以便它们能每隔24小时环绕地球一周。
The satellites sit in a very special orbit that allows them to circle the Earth once in 24 hours.
“这是紧张的两周，不知道他们何时开始，但昨天晚上他们打来了卫星电话，说终于有了飞往南极点的飞机。” 克里斯汀说。
"It's been a stressful two weeks, not knowing when they would start, but they called last night by satellite phone to say they had finally got a plane to the pole," Christine said.
