RE: Debris Hits on Endeavour

Good idea, but not too likely. Certainly not impossible. Considering the 
odds of a hit from the Leonids (At 100 times the Geminids rate) was only 
expected to damage 1 or 2 of all the satellites out there (In actuality, no 
damage at all has been reported, but the highest rate was only comparable 
to what the Geminids produce, not the hoped for storm.) The threat from the 
Geminids should have been much less, despite the longer period of activity. 
Additionally, the Geminids only approach the earth at half the Leonid's 
speed, which means 1/4 the energy, right?. In defense of the Geminids 
however, they are among the densest particles of all annual meteor showers, 
more substantial than the  smaller, lighter Leonid storm particles. 
However, velocity is the most important determinator (sure, make up a word) 
of damage. In any case, those particles are mighty far apart, and the 
Shuttle is very small, ...lost in space.


However, I fear we may be drifting a bit off topic here... :-)

Hi all,

Endeavour was in orbit at the peak of the Geminids meteor shower.
Could explain some hits.
