Rock found on Mars could be evidence of ancient life, NASA says
The Perseverance Mars rover put scientists closer to discovery ancient life on Mars, according to NASA.
“It’s not life itself,” said Nicky Fox, associate administrator for NASA’s Science Mission Directorate, stressing that this is a potential biosignature, not proof of life. The lead author echoed that caution.
“We cannot claim this is more than a potential biosignature,” said Hurowitz. Other officials also underscored the stakes and the limits.
