Bringing Martian samples to Earth -- preparations outlined in journal Astrobiology

New Rochelle, NY, August 13, 2008 A critical component of NASA's Mars exploration program involves bringing planetary samples back to Earth for in-depth analysis, plans for which are detailed in the latest issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The re...

Dig deeper to find Martian life

Probes designed to find life on Mars do not drill deep enough to find the living cells that scientists believe may exist well below the surface of Mars, according to research led by UCL (University College London). Although current drills may find essential tell-tale signs that life once existed on...

Relic of life in that Martian meteorite? A fresh look

Since the mid-1990s a great debate has raged over whether organic compounds and tiny globules of carbonate minerals imbedded in the Martian meteorite Allan Hills 84001 were processed by living creatures from the Red Planet. The materials have been under intense scrutiny ever since. Scientists at...
