But only two exomoons, or moons beyond our solar system, have been found.

但目前只发现了两颗系外卫星，即太阳系以外的卫星。

In a way, this is not surprising. Few astronomers would have bet against the existence of exomoons.

在某种程度上，这一点也不意外。几乎没有宇航员会打赌外星系不存在卫星。

If it can observe for long enough, it may turn up more candidate exomoons.

如果TESS的观测时间够长，或许可以发现更多候选系外行星。

If everything goes according to plan, the study of exomoons may follow the pattern seen with exoplanets, where an initial trickle turns rapidly into a flood.

如果一切按计划进行，系外行星的研究或许会遵循系外行星的模式—在这些系外行星上，最初的微妙移动迅速扩大。
