NASA Urged to Keep Microbes From Mars AP

While Earth germs may not kill attacking Martians as they did in “War of the Worlds,” a new study is calling on NASA to prevent contamination of Mars with microbes from our planet. NASA is planning a return to the Moon and eventually to send manned spacecraft to Mars, and the National Research Council warned Monday that if life forms from Earth were able to survive the trip they could contaminate the Red Planet.
