And then my chance really happened in 1996 when we added the second flight of the tether satellite.

And then I graduate two years later, in 1998, with my class. And, since then I've been here in Houston for training basically. And I was very happy to be assigned to this mission.

When this space walk will be completed, then the arm will be fully operational and ready for the next activity that will be pretty much the testing, the first flight testing of the space station arm.

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.

I was, I remember, I still remember when the first time I pointed the telescope at the sky and I saw Saturn with the rings. It was a beautiful image.

And so, I will be probably, since I am not involved in all the activity, I will have some spare time to devote to document all this busy part of the flight.

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.
