There has been no precipitation, as they know it, during their tenure here. It's odd, that two worlds, regardless of size, such mirror images in all other respects, don't share such simple phenomena as snow, sleet or rain. Furthering the strangeness is the fact that the vegetation thrives, despite seeming deprivation of water.

It's an accepted fact of life by now; there are much more pressing things to consider without worrying about what could merely be an environmental idiosyncrasy.

Only one passenger gives thanks for this small blessing on a daily basis, and her reasoning is sound.

She can't swim.
