The first spacewalk as outlined by Parazynski in an interview
In a pre-flight interview, Parazynski was asked about the details of the first spacewalk.
We start out on flight day 4 with our first spacewalk; Doug Wheelock and I will go out the hatch together. It will be Doug’s first spacewalk. I’m looking forward to seeing him have that experience. Our first activity right off the bat will be to transfer an S-band antenna that will be returned to the ground for servicing and then flown back up, on a future flight as a spare. The reason we have to do it so early in the flight — it’s not our highest priority activity; it’s just that’s the only time the robotic arm is available and in position to support this activity. So we’ll pluck this off of the Z1 Truss through a handoff, we call it a leap frog maneuver. Doug will hand the SASA antenna to me; it’s about 10 feet, 8 to 10 feet in length. I’ll hold on to it, then he’ll jump into the space station robotic arm, I’ll hand it back to him, then he’ll take a beautiful ride down to the payload bay, while I translate hand over hand, to support him in installing that on the sidewall of the orbiter for return to Earth. Then we really get into the meat of our assembly activities. We’ll activate the Node 2 or Harmony module in the payload bay. First we’ll be translating a payload and grapple fixture that’s on a sidewall in the payload bay, and we’ll temporarily stow it on the front end of the, the node. And I’ll get a free ride to its installation location up on the Node. So we’ll just tether it in place up on the front of the Node and then we’ll go to the back of the payload bay and we’ll move some protective covers on the seals that we’ll mate to the, the Node 1, or Unity Module, while we’re up on station. We’ll also work with some power connectors, the launch activation cable on the front of the module and some other cables on the back of the Node. Once we’re completed with all our work in the payload bay, we’ll translate back up to the airlock and drop off some gear, and then we’ll head up to the P6 truss. Again, these are all independent, closely choreographed, tasks. I’ll begin demating the cooling umbilicals that have been connected between P6 and the Z1 truss for almost seven years now. So I’ll have to close those valves very carefully and stow them back on the Z1 truss. We’re hoping for no leaks, but since the valves have been operational for so long, that’s one area of concern that we don’t want to get any contamination. While I’m doing that, Doug will be up on the P6 truss about 10 or 15 feet higher than me, and he’ll be deploying a blanket over the, the radiator there. I will join him for the final activities associated with that radiator blanket. And then we’ll go to the top of the world, the top of the P6 truss, and we’ll be installing two protective thermal blankets on Sequential Shunt Units. They’re basically large power boxes, associated with each of the large P6 solar arrays. So we’ll put those blankets on, probably take a few pictures, I imagine, ’cause that vantage point up there is just spectacular, and that will be the completion of our first spacewalk.
