➡ New study discovers that ‘flowing water’ on Mars may be sand and dust
================
▪️According to a study published in the journal Nature Geoscience, dark features earlier thought to be evidence of liquid water flowing on Mars may actually be granular flows comprising sand and dust.
▪️The new findings indicate that the water-restricted conditions on Mars would make it difficult for Earth-like life to exist near the surface of the planet. The study is based on observations made with the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
▪️The researchers had discovered narrow, down-slope trending surface features called Recurring Slope Lineae (RSL) on Mars in 2011. The features were found to be darker than their surroundings.
