Watch your head! NASA is reporting that 2 old satellites crashed
yesterday over Siberia. 500 miles over Siberia that is. What I
find amazing are these factoids: - At the beginning of this year
there were roughly 17,000 pieces of manmade debris orbiting
Earth. - There are people with the title "orbital debris
expert". - orbital debris is now the biggest threat to a space
shuttle in flight, surpassing the dangers of liftoff and return
to Earth. So this begs the question: How the hell does a
satellite orbit anyway? Basically once it is placed in motion at
the right velocity - it falls towards the earth at the same rate
the earth curves. So, it never comes back to earth - eva! I love
stuff like this.
