Article Synopsis
- Sodium chloride (NaCl) is significant across various fields, including geochemistry and food production, and is one of the most prevalent salts in the cosmos.
- Researchers discovered a new form of NaCl, a metastable dihydrate, created by rapidly freezing a NaCl solution, which transforms into hydrohalite and ice Ih when heated above 190 K.
- This finding suggests that the presence of this new hydrate on icy celestial bodies, like Jupiter and Saturn's moons, could indicate areas where subsurface brines have recently frozen, highlighting potential targets for future space missions.
The European Space Agency (ESA) and Roscosmos ExoMars mission will launch the "Rosalind Franklin" rover in 2022 for a landing on Mars in 2023.The goals of the mission are to search for signs of past and present life on Mars, investigate the water/geochemical environment as a function of depth in the shallow subsurface, and characterize the surface environment. To meet these scientific objectives while minimizing the risk for landing, a 5-year-long landing site selection process was conducted by ESA, during which eight candidate sites were down selected to one: Oxia Planum.

These ridges are interpreted as depositional fluvial channels, now preserved as inverted topography. Here we use high-resolution image and topographic data sets to investigate the morphology of these depositional systems and show key examples of their relationships to associated fluvial landforms.
