Pre-flight NASA Interview with Scott Parazynski: any concern unfolding the solar arrays?

Is there any concern with redeploying those solar arrays? They had a little trouble getting them back in. But they did successfully get them back in with a little help from some EVA astronauts. Any concerns about unfolding them again?

Well, as the lead spacewalker on the flight it’s my job to worry, I suppose, and so there are a number of contingencies that we could find ourselves in, in terms of deploying those solar array wings. Our advantage is that in the deployment we can apply more tensioning force as the wings deploy. So it’s less likely that the solar array panels will bind up as they unfurl from the blanket boxes. But there certainly is potential and we trained, quite extensively, not only in the water – where we practice a lot of our spacewalking activities – but we have a 1g simulator here in Houston, at the Johnson Space Center, where we can actually get hands on with real solar array hardware.
