Today, U.S. Space Command is tracking more than 40,000 objects in space and only about 5,000 of them are active satellites.

今天，美国太空司令部正在追踪太空中超过4万个物体，其中只有大约5000个是活跃的卫星。

The pilot who was tracking the object described it as being spherical and having a green afterburn.

跟踪该物体的飞行员将其描述为球形并有绿色余热。

A big part of LeoLabs mission is not just tracking objects in space, but actually making sure that satellites don't collide into each other.

LeoLabs 任务的很大一部分不仅仅是跟踪太空中的物体，而是确保卫星不会相互碰撞。

But equally, it's useless to use solar time while tracking objects in space, because the region you're observing would shift between say, 10: 00 PM one night and 10: 00 PM the next night.

但同样，在跟踪太空中的物体时使用太阳时是没有用的，因为您观察的区域会在前一天晚上 10: 00 到第二天晚上 10: 00 之间变化。
