Early as 8am we went to the ISA Space Geodesy Centre near Matera. Professor L. Garramone welcomed us and presented with a lot of teaching the basic principles of space geodesy and some of the many activities in which the center is involved: measuring the Earth-Moon distance, the size variations in the Earth's crust; monitoring tectonic plates, marine pollution in the Mediterranean Sea; management support and prevention of natural disasters; gravimetry etc. The listening was very attentive and we were allowed to visit some of the facilities.
