  • A map of the stability of brines on Mars, obtained by combining thermodynamic and climate modelling, shows that some brines can stay liquid for longer than previously thought, particularly at high northern latitudes. However, they are not habitable to known terrestrial life, and can be explored without risk of biological contamination from Earth.

The 305 m radio telescope at the Arecibo Observatory withstood the storm, suffering only minor structural damage. Staff have worked diligently to return the site to full operations and provide vital services to the surrounding Puerto Rican community.
