Nice! ;) LOL

Subject: [meteorite-list] Panspermia, Reverse Panspermia & Life In Space
Hi list,
I know I've posted a lot today, but bear with me. I've been doing
some research since I found the article on the meteorite that Mars
rover Opportunity found on Mars earlier and it got me to thinking
about how it got there and where it was from. This led to more
research and more questions...
We know meteorites come from other celestial bodies, whether they be
from asteroids, comets, or planets. All types of meteorites have been
found on Earth but... What about the reverse?
We know it happens because we have lunar and martian meteorites here
on Earth. Over the last few months I've been reading about panspermia
and artificial planet seeding too which are very interesting topics.
You can imagine the force a huge asteroid would exert on the crust of
our planet during an impact event and would eject quite a bit of
material into space.
This all brings up some very interesting questions... If Panspermia
is a theory, then wouldn't reverse panspermia (life originating from
Earth) suggest it's very plausible and not just possible to seed life
on other planets from another by impact, travel and time?
Having said that let me illustrate a scenario. A huge asteroid
impacted Earth millions of years ago throwing millions of tons of
debris into our atmosphere. Some of this debris will escape Earth's
gravity and make it into space. How much is arguable. Wouldn't it be
possible for some microbe or bacteria to be preserved deep inside a
clump of Earth, and flash frozen in the iciness of space?
How many billions of bacteria, and microbes, or even insects have
been launched into space over the hundreds or even thousands of large
impacts the Earth has been subject to since the beginning of time?
Look at the jungles of South America and Africa and other tropical
regions. The density of life in any given square foot is higher than
on any other place on the planet. If a large Asteroid impacted this
region you can imagine the sheer numbers of "life forms" that escaped
Earth.
Survivability is the issue. If the microbe or "life form" is deep
enough within the stone, rock, or clump of earth, wouldn't it be
preserved. wouldn't this Earth rock act as a capsule to transport
life outside our own solar system? Current science tells us that the
temperature of the interior of a meteoroid entering our atmosphere is
relatively low. In fact it is usually ambient to space. In other
words cold! Frozen even. This is sufficient to allow a microbial life
form to survive isn't it? Look up Water Bear on Google...

Wouldn't this mean that there could be space rocks out there with
"life" within them right now? Life that came from Earth? And if
there's life out there that comes from Earth, it wouldn't take a
rocket scientist to guess that there might be other material out
there that might just have come from another habitable solar system.
I know these are big jumps and guesses, but isn't it possible
considering the sheer length of time, the age of our planet, and the
number of impact events over this time period on other celestial
bodies and planets?
I mean we are talking about billions of years here...
Your thoughts?
