Russia Tests Life From Mars Theory

One theory that scientists have been trying to test for a long time is wether life could have arrived on Earth from Mars. The theory is that meteorites could have brought life from Mars to Earth. The University of Aberdeen set out to test this theory by attaching a rock to an unmanned Russian spacecraft. The tested the effects of traveling through the atmosphere to gauge if life could have survived. 

Scientists concluded that life could have probably only survived in large meteorites. Th heat was would have been too extreme on small meteorites. While this does not affirm or negate the theory, scientists now have even more information available for their disposal.
