Re: Galaxy 3C

Yes Raoul, and I completely forgot about the launch. I was going to watch it on line. They have had problems with the 702. The last I heard, they still didn’t know the exact cause of the reduced reflectivity of the concentrators. Some sort of outgassing that they can’t pin down. There was concern that the ion engines might be the cause, but the last I heard they didn’t know, or at least weren’t saying. Anyway they gave up on the concentrators and just added a panel on each wing to make up for the lost output. Seemed like a simple solution, but there’s more to it than that of course. Changes in weight, center of gravity, etc. etc. You have to revisit every system to see what effect that would have on them. I’m sure some fingers are crossed hoping they thought of everything.
