很可能你看到的是一艘低轨宇宙飞船反射的太阳光，因为这些航天器每90分钟左右绕地球一圈。
What you are seeing, most likely, is a spacecraft in low Earth orbit reflecting back sunlight as it circles the Earth once every 90 minutes or so.
如果飞机有这样的速度，在一分钟多一点的时间内就能够绕地球一周。
At that velocity, an airplane could circle Earth in little more than a minute.
同样，OCO也会研究太阳反射光线中的二氧化碳和氧气特征光谱，它将于705公里的上空以99分钟绕地球一圈的速度飞行。
OCO will similarly study carbon dioxide and also oxygen signatures in reflected sunlight. It will fly at an average altitude of 705km and orbit the Earth about every 99 minutes.
