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.

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

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.

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.

Also we will be carrying food and clothes for the Expedition Two crew. And as well as spare parts for the EVA that will be conducted from the station in the following months.

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.
