Walter Hohmann (1880-1945) in his book "The Attainability of Celestial Bodies" carried out seminal work on interplanetary  travel.
"Hohmann's great contribution to astronautical progress was the discovery of a new use for an old objec: the ellipse"
(William McLaughlin)

In the last decade the whole process of planning, selecting and realising a space mission has undergone substantial changes, in particular as concerning scientific missions. Large space projects, which needed typically 10 years realisation times (from proposal to launch) and budgets of the order of 500 M$, proved to lose momentum with respect to both, the fast advances in miniaturization and computer science, and the steady decrease of funding devoted to space activities. Thus all major space agencies have developed novel strategies in the light of the better-faster-cheaper paradygm. This resulted in the development of standard platforms and the reuse of existing payloads as well as in fully exploiting the possibility offered by small satellites and launchers in terms of reduced cost and development time.

Within this framework, experience has been gained in the many different aspects involved in the realisation of a space mission: developing general purposes tools for mission analysis for both near-earth (OPA - orbit perturbation analysis - software for high precision orbital evolution of high eccentricity and inclination telecom satellites) and interplanetary missions (modelling the Cassini/Huygens probe descent into the windy atmosphere of Titan); experiencing an operational environment (SAX, the Italian X-ray satellite launched in 1996); proposing new missions (MERCURY POLAR ORBITER, PIAZZI, LOCO, AROS, NEARER); participating to both the Science Teams (PIAZZI, MASTER) and the Study Teams (CASSINI, ISHTAR, SIMONE) in charge of bringing mission proposals to a phase-A level system study; following the management of space programs, in particular concerning the interrelations among the European Space Agency, the national agencies of the member states and the aerospace industrial community.
Relying on these experiences, specific studies are also carried out on topics directly connected to space mission design. As an example, the H-plot targeting strategy for missions aimed to the Near Earth Asteroids has been proposed for making more efficient the exchange of information between the science team and the technical counterpart: the choice of a suitable target in fact involves at the same level mission analysis and scientific considerations, which in turn implies the interaction among different methods and different communities. In this respect, the H-plot method has been successfully applied during the phase - A studies of the missions ISHTAR (a rendezvous mission for studying the internal structure of a NEA - proposed by Astrium Ltd) and SIMONE (a fleet of small satellites for NEA characterization - proposed by QinetiQ), selected by ESA after its ITT "NEO Space Mission Preparation".

As a member of the CELMEC meetings organising committe, is in charge of  the sessions devoted to spaceflight dynamics.
