Behnken and Hurley are more than crewmates: they are also good friends. They entered the astronaut corps at the same time – the class of 2000; they both married astronauts; they were even in each other’s weddings.
Both flew twice to the International Space Station on separate space shuttle missions. Now they’re preparing to fly together – an experience that’s not just enjoyable, but helpful as well.
“We can think ahead in terms of what the other person is going to need, or what the other person is going to want, anticipate the next input, all those sorts of things, which really, in a test flight like this, goes a long way,” Behnken said. “You can really anticipate the other person’s reactions versus to have a, ‘Well, I don’t know, Doug. How do you feel about the next series of events?’ I already know the answers to those questions, and it makes a big difference when you’re doing something as critical as spaceflight.”
