Abstract:

This NASA website provides a summary of a study led by NASA's David McKay that may provide evidence for past life on Mars. McKay and his team found carbonate globule features on the ALH84001 meteorite that appear to be nanofossils. In addition, secondary mineral phases and hydrocarbons provide further evidence for past life. The website features color photographs as well as links to related web pages.
