No, the mirror adjustment screws (7 on each mirror) are apparently screwed all the way down so the mirrors are against stops. This would be to be able to handle the g forces from launching. They must all be unscrewed to the 1/2 inch point, then fine tuned. This would give each mirror the ability to move 1/2 inch up or down I suppose. This assumes a 1 inch range of travel. The mirror actuators move "as fast as grass grows" so it should take a few weeks to get them roughed into place. This could be done while it travels to L2 and does some more cooling down. Then there are a few months of tweaking I believe. This could be done with red light, which does not need the cool down.
