NASA has already found signs of alien life on Mars but is still keeping it secret, a rogue scientist claims.
Barry DiGregorio, 71, believes rovers from the space agency captured snaps of alien fossils on two different occasions.
In 2018, Nasa’s Curiosity rover took images of what it said likely show crystal growth.
But DiGregorio accused Nasa of failing to investigate properly and spent two years researching the images himself.
The author, who wrote Discovery on Vera Rubin Ridge, Trace Fossils on Mars, then concluded they were “biogenic” – meaning they were produced by living organisms.
He theorised Nasa was staying tight-lipped to boost interest in its hopes of sending humans to the Red Planet in the 2030s .
DeGregorio, an honorary research fellow at Buckingham Centre for Astrobiology, now claims Nasa found yet more evidence of alien life on Mars.
He believes images snapped by the Perseverance rover in 2020 show signs of “worm-like” aliens who roamed its historic oceans.
The astrobiologist told The Sun: “I watched the rover coming down right on its landing site.
“You could see the engines just brushing all the dust aside for the rocks to become apparent, and the very first images it took were these rocks that had holes in them.
