ESA's ExoMars Orbiter Reveals 'Smiley Face' Salt Deposit on Mars, Suggesting Evidence of Ancient Life
The European Space Agency's ExoMars Trace Gas Orbiter has captured an image of a unique salt deposit on Mars that has a smiley face shape. Scientists believe that this feature could be evidence of ancient life, as it represents the remains of lakes and rivers that once existed on the planet.
The discovery sheds light on Mars' past climate and raises the possibility that it may have supported life in the past, providing new insights into the history of the Red Planet and its potential habitability.
