Ancient life on Mars?
Article Abstract:
Scientists admit that the minerals, organic residue and bacteria-like structures found in a meteorite believed to originate from Mars does not provide conclusive proof that life once existed on the planet. The meteorite was discovered in 1984 but identified as one from Mars only in 1994.

Article Abstract:
Victor Baker, Robert Strom and their colleagues suggest that Mars could have episodically had an Earth-like atmosphere, an ocean and ice sheets. The planetary geologists believe this hypothesis would explain Martian surface features such as apparent ocean shorelines and giant channels.
