“We’ve got a whole host of things that could cause us to not get off on any given day,” mission manager Mike Sarafin told reporters at a Thursday evening news conference. “There’s no guarantee we’re going to get off (Saturday). But we’re going to show up, and we’re going to try, and we’re going to give it our best.”
