Of relevance to my next book, Water, is the question of subglacial water.
Here’s reporting on a recent study that modeled glacial movement on Mars. It has been assumed that most glaciers on Mars have been frozen to their beds for quite some time. The question has been, did they ever move or have they always been stuck? This study suggests that they may have been able to move in the past, though more slowly than glaciers on Earth.
It’s an interesting piece, but doesn’t help my case. For Water, I need a significant reservoir of subglacial water in the present. This is where I’m going to have to exercise some creative license and claim that remnants of ancient vulcanism have kept my fictional ice sheet wet at the bottom. At some point in any work of science fiction, one must lean into the fiction part. This is where that happens for Water.
