Meanwhile, back on Mars... I’m checking out these stick-like figures. Each is about a quarter-inch long. Maybe they're crystals? Or they could be minerals that filled spaces where crystals dissolved away. Stay tuned! Science continues.

Layers of meaning! These rocks show the deep and shallow waters of an ancient Martian lake could've supported different kinds of microbes. This evenly layered rock imaged in 2014 by my Mastcam shows a pattern typical of a lake-floor sedimentary deposit near where flowing water entered a lake. Shallow and deep parts of an ancient Martian lake left different clues in mudstone formed from lakebed deposits. Credit: @nasa/NASAJPL-Caltech/MSSS
