Rex just might be right, here
Not only is mister Milton-I'm-too-busy-to-have-a-heart-attack actually reworking his satellite plans on his own, which will mean the engineers have to work overtime to set things right - he's making the thing heavier. It's supposed to be light. Hence, carbon fiber - the preferred material for space. Plus, what difference does it make how many kilos the camera weighs? Rest mass is meaningless! It'll be in space, Milton. Weightless! If the bearings survives the launch, they'll hold the camera up just fine.
And what's with the gratuitous digs at the French (who, by the way, you hired)? The French have been putting satellites into space for almost 50 years (since 1965) and have a fine track record, with over 50% of the market for civilian launches plus holding the record for heaviest commercial payload.
Milton, my boy, you really ought to check into that hospital Rex is recommending for you. Before you ruin this multi-billion-dollar deal with your midnight doodling.
