Yesterday we started losing people, after reaching our peak population. With all the half-wave plates installed, Sean and John departed. Insert assembly also started wrapping up.
And some of us set some equipment up in the Bemco chamer, for thermal/vacuum testing (round 2). Everything that flies must be tested to ensure it will survive.
