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". http://www.esa.int/gsp/completed/neo/index.htm
