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. Kevin ===== COSPAR Site #1775 Long 75.6910 W, Lat 44.6062 N, altitude 100 metres __________________________________ Do you Yahoo!? Yahoo!
