但与每天24小时盯着地球同一个区域的气象卫星不同，一般情况下泰拉和阿卡只能各获取一张有关墨西哥湾的白天视图。

But unlike weather satellites that look at the same region on Earth 24 hours a day, Terra and Aqua generally only get one daylight view each of the Gulf of Mexico.

泰拉的视图大约是在每天中午前不久，而阿卡则是中午过后不久。

Terra’s view is shortly before noon each day, and Aqua’s is shortly after.

大多数地球大观发布的有关浮油的图像是来自同时搭载于泰拉和阿卡卫星上的，叫做MODIS的传感器的数据的副本。

Most of the images of the oil slick that the Earth Observatory has published come from a sensor called MODIS, a copy of which flies on both the Terra and Aqua satellites.
