A huge lake of salty water appears to be buried deep in Mars, raising the possibility of finding life on the red planet, scientists reported Wednesday.
The discovery, based on observations by a European spacecraft, generated excitement from experts. Water is essential to life as we know it, and scientists have long sought to prove that the liquid is present on Mars.
“If these researchers are right, this is the first time we’ve found evidence of a large water body on Mars,” said Cassie Stuurman, a geophysicist at the University of Texas who found signs of an enormous Martian ice deposit in 2016.
Scott Hubbard, a professor of astronautics at Stanford University who served as NASA’s first Mars program director in 2000, called it “tremendously exciting.”
“Our mantra back then was ‘follow the water.’ That was the one phrase that captured everything,” Hubbard said. “So this discovery, if it stands, is just thrilling because it’s the culmination of that philosophy.”
