  2. Political Status • C-MIN 2008 Decision: • In November 2008, ESA member states indicated they would subscribe 850 M€ for the ExoMars mission, to be launched in 2016; • Together with the national investments for instruments, this corresponds to approximately 1 B€ (1.3 B$) • Also in November 2008, ESA member states made a long-term commitment to European Mars exploration: • MREP: Mars Robotic Exploration Programme • – Up to 40 M€ (50 M$) available for studies leading to a series of missions to Mars. • – Programme to be based on international cooperation —first and foremost with the USA.

  4. Mars Robotic Exploration Programme • A joint ESA-NASA Mars exploration programme: • Aim is a long-term European Mars exploration line of ~200-300 M€ per year. • More science and technology opportunities; • International cooperation has a programme stabilisation effect; • Measurement objectives can be spread over several missions; • Scenario under consideration: • 2016: ExoMars, ESA-led exobiology rover mission; • 2018: TBD NASA-led rover mission, with likely focus on exobiology in continuation of ExoMars; • 2020: Network of landers dedicated to geophysics and environment;

  5. ExoMars International Status • International cooperation has been mandated from the very start for ExoMars; • – From the very beginning: • – US contribution to organics detection instruments on the Rover; • – Cross support with Russia for ExoMars – Phobos/Grunt. • Situation is now evolving —following slides.

  6. Financial Realities • The 850 M€ for ExoMars is less (approx. 85 %) of the request made by ESA to member states; • – The mission as proposed would require contributions (from all sources, national and international) in excess of 1.2 B€. • – In an ESA optional programme there is no mechanism available to make up financial shortfalls (e.g. unlike BepiColombo where money can be moved from other missions). • – Accordingly, not only is international cooperation necessary, but some descoping of mission capabilities is unavoidable.

  7. Ongoing ExoMars Actions • Intensive mission analysis work taking place with NASA, focusing on a restructured joint mission in 2016 within new concept of long-term cooperation; • Series of meetings with Russia to discuss the possible provision of a launcher and potential science contributions; • Major review of payload under way —to set priorities and assess readiness— some instrument descoping is inevitable. • Major project review (Interim-PDR) will be completed in March 2009. • – Its aim is to consolidate the mission design and technology development work carried out so far.

  8. 1200 M€ • 1200 M€ • ESA: •  ESA: • NASA: •  NASA: • US contributions to Rover instruments • US contributions to Rover instruments • Cooperation for ExoMars • Previous Baseline • Possible New Baseline • Previous Baseline • Possible New Baseline • – Launcher • – Launcher • US data relay • Data relay carrier • 75 M$ • 75 M$ • + Launcher • + Launcher • Russia: •  Russia: • + Launcher • + Launcher
