In particular, this arm has 7 degrees-of-freedom that makes the overall motion of the arm very complex so that, before you start driving the arm, you should be very familiar with all the position it can get.

But, what we need to get out of the first EVA is to have the arm completely unfolded and powered so that they can keep the temperature under control. That will really the call of the first EVA.

I started this whole endeavor really. And at the beginning we had the selection in Italy. And that was pretty much among people that had held previous experience in that particular satellite. So, I was in that, in a good position then.

During that space walk there will be some repositioning of the power so that the arm can be fully controlled by the robotic station that is in the Lab.

At that point, there will be the handover between the shuttle arm and the station arm so that the shuttle arm will take the cradle and put it into the cargo bay.

Well, we have two major goals. The most important one is to get the station arm on board the station, because that's this really milestone in the space station building since from now on they will be using this arm to continue building the space station.
