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.

I remember; I was 15 years old when Neil Armstrong put feet in the moon.

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.

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.

For the first time in history all the major countries in the world are pushing together to reach this goal... building something in space that is really for all humankind.

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.

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.
