Case for Life on Mars: Biomarkers Found in the ALH84001 Martian Meteorite Again
New chemical and fossil evidence of ancient microbial life on Mars carried to Earth by the famous Allan Hills 84001 meteorite is now withstanding the test of time through utilzation of more highly advanced High Resolution Electron Microscopy confirms the remains of life —in the form of fossils—of bacteria-like lifeforms.
After having first burst into global mass media awarness with a press conference by President Bill Clinton in 1996 announcing the ancient life form from Mars, the Allan Hills 84001 meteorite encounted opposing theories among astrobiology scientists. But the new and more detailed data on magnetite crystals and carbonate discs now available largely counter a wide range of opposing theories on the ancient fossil bacteria-like lifeforms.
SpaceFlightNow has a detailed article on the new paper and other publications coming from the original NASA science team that advanced the ancient life theory on Mars contained within the Alan Hills 84001 meteorite.
In 1976 there was debate as to life on Mars as well and more than three decades later, scientists have concluded there was once and may still be large amounts of Mars water.
