    While the icesat has a 532 nm laser on board, another one to be launched is called cloudsat will
    also have a 532 nm laser on it:) So two lidar sat's.
    
    Also remember seeing awhile ago, nasa was going to do some satellite formation flying.
    
    I found the details of it at
    
    http://aqua.nasa.gov/docs/A-Train_Fact_Sheet.pdf
    
    For the seperation of cloudsat and calipso, they say seperated by no more then 15 seconds. Being
    in a 700 km orbit, and assuming they travel at 0.62 degrees per second when overhead, then that
    works out to be approx 10 degrees seperation between them. Now that should be cool to see, when
    you can see them.
