haha, its all good. The only reason I knew that is that I have a popular mechanics magazine with a graph that shows every single shuttle launch from
1969 to 2004, and 98% percent of all those stopped at the point in the atmosphere where because of the effects of gravity, you can pretty much easily
get into a geosynchronous orbit around the earth without plummeting back to earth.
But thats a good question about the microbes around the shuttle. My only guess is there isnt that much mass for the microbes to accumulate on in that
layer of the sky. but your still under the Van Allen radiation belt
, which keeps some
pretty nasty cosmic rays from killing us instantly, or at least covering us with radiation.
The moon has virtually no atmosphere, and it gets bathed in cosmic rays all the time, which is why it would be alot safer to make a human facilitated
base on mars, because the atmosphere of mars acts in a similar way to the earths.
The main reason we dont need to send people off to study Titan or Venus or any other extrasolar planet or mass is because, simply put, robots do a
MUCH better job at collecting data and they are exponentially more efficient at data collection than any human (They dont sleep). If you where to take
the 9 month trip to mars, 95% of all the weight in your vessel would be food and water and stuff to make the trip not mind numbingly long. When we
send probes and data collectors, we dont have to worry about life support systems, air, water, heating and cooling, which makes us able to pretty much
fling a toy into space and let it send the numbers back to us.
