!!! Thank you all very much !!!

In a Science Class in School Ricardo and his Classmates sent Balloons to the Stratosphere equipped with different Measurement Instruments (Project 'Ikarus'). Below are Autographs from Astronauts and Cosmonauts, Aviators, NASA Staff and Nobel Laureates on a picture taken during the 'Ikarus' Flight in the Stratosphere (32 km). The Figure was used to center the Camera.
