在赞扬航天飞机带来的成就和观察地球的独特视角时，我们提供了一个新的照片功能：每次飞行，都是地球的使命。
In tribute to those achievements and to the unique view of Earth that the shuttle has provided, we offer a new photo feature: Every Flight is a Mission to Planet Earth.
这项功能允许两位玩家在对方出着时进行观察。
This feature allows both players to see when the other player moves.
认识到这个软件的功能，第一时间的用户常常抱怨这种快乐而又颇具启示性的苦闷，因为频繁的地球旋转和从一个观察点换到另一个，甚至让用户感到晕头转向。
First-time usersoften report an exhilarating revelatory pang as they realise what the softwarecan do. As the globe spins and switches from one viewpoint to another, it caneven induce vertigo.
