Panspermia - A Radiating Experience
Berlin, Germany (SPX) Feb 07, 2006
In this interview with Astrobiology Magazine, Gerda Horneck of the German Aerospace Center discusses the effects of space radiation on life. She has spent her career studying the controversial concept of Panspermia � that life could be transported between different planets by meteorites. She has also looked at issues faced by human astronauts as they venture into space and explore other worlds.
Latching Onto Lichen
Moffett Field CA (SPX) Dec 06, 2005
Bacteria can often survive the harsh conditions of space, and their toughness and adaptability have made them key candidates for the transfer of life between planets. But in a recent study by European scientists, lichen survived a trip in space even better than bacteria do.
