And just when we were at the end of our design process there was the news that the Italian government and the U.S. government had signed an agreement to fly the first Italian astronaut on that flight.

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.

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.

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.

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.

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.
