We've arrived in Houston! Updates soon to come on the first day's activities and surprise events. First, here's a look back on our last minute assembly and subsystem integration of our ratiometric fluorometer for microgravity flight. This device detects real-time calcium flux in bone cell culture...or any cell culture that is! We've already determined some interesting sample candidates to test for fluorescent properties (Sondra's hair made the top of the list!).
