  ABSTRACT: In the Italian high-schools the space is not a central argument: usually a student learn a little bit of astronomy in general courses of science, and, if the school is a scientific-oriented one, a student studies the law of gravitation with some astrodynamics application in the course of Physics. Every year the Department of Mathematics of the University of Pisa organizes an open week for high school students interested in mathematics and applications: several workshops on various themes are arranged by professors with the help of undergraduate students. In the last edition I held for a first time a workshop entitled ``From the Newton's apple to the space age: the mathematics in orbit'', in which I talked about the historical and conceptual development of celestial mechanics and astrodynamics, arriving to describe some research arguments, such as impact monitoring of near-Earth asteroids and orbit determination and correlation of space debris. Of course the workshop has been extremely interactive, leaving time to students to discuss and to try to solve exercises. In this presentation I would like to share this experience highlighting the educational methodologies used and the students' response, also discussing some ideas for future workshops of this kind.

  ABSTRACT: Juno is a NASA New Frontiers mission to the planet Jupiter, launched from Cape Canaveral on August 5, 2011. The spacecraft will arrive to Jupiter in 2016 and will be placed for one year in a polar high-eccentric orbit to study the composition of the planet, the gravity and the magnetic field, and the magnetosphere. The Italian Space Agency (ASI) contributed to the mission providing the radio science instrument KaT (Ka-Band Translator, developed by the University of Rome ``La Sapienza'' and Thales Alenia Space) used for the gravity experiment, which has the goal of studying the Jupiter's deep structure by mapping the planet's gravity. Such instrument takes advantage of synergies with a similar tool in development for BepiColombo, the ESA cornerstone mission to Mercury. The Celestial Mechanics Group of the University of Pisa and SpaceDyS s.r.l. are responsible, under an ASI contract, for the development of an orbit determination and parameters estimation software for processing the real data independently from NASA software ODP. We shall present the state of the art of such software highlighting the theoretical models used, the problems addressed and first results about the scientific goals obtained with simulated data.
