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

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.

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.

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 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.

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.
