摘要

The long-term cooperation plan established by ESA and NASA in June 2009 has made further progress toconsolidate the two missions of the ExoMars project as the System PDR was held in December 2010 and theIndustry Consortium submitted a committing Price Proposal for the project C/D Phase in February this year.This paper addresses the ESA-led mission, to be launched in 2016, which comprises a Trace gas Orbiter (TGO), withscientific and data relay assets, and an Entry Descent and Landing Demonstrator Module (EDM).On January 2016 the ExoMars Spacecraft Composite (SCC) will be launched by an Atlas V 431 "type" vehicle, fromCape Canaveral Air Force Station (Florida, USA), into a Type-2 transfer trajectory to Mars which will be reached,after a cruise of about 9-month duration, on 16 October 2016.The EDM will be separated from the TGO and will coast autonomously for 3 days before crossing the EntryInterface Point (EIP) at 120 km from the Martian surface, from which it will perform the hyperbolic entry, descentand landing at its Meridiani Planum landing site (Longitude = 6.15 deg W, Latitude = 1.82 deg S).Twelve (12) hours after deploying the EDM, the TGO will execute the Orbiter Retargeting Manoeuvre (ORM) toraise the pericentre of the incoming hyperbola and avoid collision with Mars. This will be followed by the MarsOrbit Insertion (MOI) which will put the TGO into a highly eccentric orbit with period of 4 sols.At the second apocentre of the insertion orbit, 6 sols after MOI, an inclination change manoeuvre (ICM) will takeplace to reach 74 deg, the target inclination of the science (and data relay) orbit; at the next pericentre, 8 sols afterMOI, the Apocentre Lowering Manoeuvre (ALM) will be performed in order to reduce the orbital period to 1-sol.Further reduction of the apoares will be then achieved by aerobraking over a period of several months, to reach thefinal science and data relay circular orbit at an altitude of about 400 km in which detection, characterisation andsource- localisation of the Mars atmospheric trace gases will be performed for a period of one Martian year.The science mission will have to be interrupted for few days in January 2019, to overview the arrival of the ESANASAjoint Rover mission, to be launched in 2018.After that, the science mission and the Rover data relay mission will continue in parallel until, nominally, end of July2019, followed by further relay operations for future ESA-NASA missions to Mars through the end of the year 2022.
