Curiosity rover has snapped what may be trace fossils on the red planet, he says Geomicrobiologist Barry DiGregorio says they resemble features here on Earth Nasa is covering up the find so manned mission in 2030s can explore in depth, he claims Evidence of life on Mars is being covered up by Nasa , according to a researcher Barry DiGregorio at a Buckingham University. The agency’s space explorer, the Curiosity rover, has snapped what may be trace fossils created by soft-bodied creatures on the red planet, he says. An upcoming 'bombshell' report will reveal how Nasa is aware of the find and has chosen to keep it hidden from the public, the scientist claims. The controversial scientist believes the space agency could be ignoring the find because of its plans for a manned mission in the 2030s, when astronauts will explore Mars in more depth. However, according to Nasa, the shapes captured in images from Mars are simply rock crystals that are currently undergoing analysis.
