Kent physicists have tested what would happen if a piece of
rock containing microscopic fossils from Earth was launched into space and hit
the surface of the moon.
In order to
do this, Professor Mark Burchell and researchers from the University's Centre
for Astrophysics simulated the condition that fossilised diatoms -- microscopic
algae with detailed shells -- might have faced if travelling from earth to the
moon.
The team
turned fossil-filled rock into powder which was mixed with water and frozen to
replicate a meteoroid. The replica meteoroid was then fired into a bag of water
using a large gas-powered gun to allow it experience the impact of being
launched into orbit, whilst the rapid deceleration and high pressure as it hit
the water simulated how it might have smashed into the moon at high speed.
This
suggests that if earth meteorites are ever found on the moon -- in the same way
that we find lunar meteorites on earth -- then they may contain fossils from
Earth's past.
Although
this idea has existed for over a decade, the researchers have now shown by
simulating the 'explosion' that it may be possible. This could then shed light
on what life was like on Earth.
The research
has been published in Philosophical Transactions of the Royal Society A.
