Nasa's Curiosity Rover Data Boosts Hope for Liquid Water on Mars
Research from Nasa's Mars rover Curiosity has strengthened hopes that liquid water may exist near the surface of Mars, astrophysicists said on Monday.
The clue comes from the presence in the soil of calcium perchlorate, they said.
This is a type of salt that is highly absorbent and lowers the freezing point of water so that it remains liquid.
The compound is a signature of "very salty salt water a brine," according to the study, appearing in the scientific journal Nature.
