On Garrett Reisman’s first flight on Endeavour in 2008, he packed his high school physics teacher’s rosary beads, a Christmas card from a friend who had died in the Sept. 11 attacks and a gold chain his late father wore. He also carried two pairs of wedding rings for his former California Institute of Technology professor Christopher Brennen. Reisman had met Brennen as a graduate student. When Brennen’s 21-year-old son died in a car accident, the two grew closer.
