 For me, the most powerful reminder that God was with me came in the form of the Eucharist. One of the most dangerous activities we do as astronauts are extravehicular activities. EVAs are spacewalks. And I've gone out the door of the International Space Station five times, spending 32 hours outside in the vacuum of space. And each morning of those spacewalks, before starting to get suited up in the quiet of my crew quarters, I received communion in the knowledge that no matter what happened over the next 15 hours, Jesus was with me.
